Description

  The present invention relates to an energy transaction management device and an energy transaction for managing an energy transaction between a transaction requesting device that requests an energy transaction and a transaction response device that responds to an energy transaction request when a condition is satisfied. The present invention relates to a management system and an energy transaction management method and program.

An example of energy trading is electricity trading.
And in the accounting method of the electric power traded between charging / discharging facilities, such as a charging stand and an electric vehicle, a management apparatus measures the electric energy which the receiving side received, for example. And the method of charging based on the electric energy which the management apparatus measured is proposed. In other words, this method makes it possible to charge the traded power without directly exchanging power charges between the charging station and the charging / discharging equipment such as an electric vehicle, thereby improving the convenience of trading (for example, Patent Document 1).

JP 2010-79456 A

In such a power transaction, the billing of the amount of power to the power receiving side varies depending on the contract form with the power company on the power feeding side. For example, there is a contract form in which the price of the power charge varies depending on the time zone. For this reason, the user has to perform charging in consideration of a fee that varies for each time zone in addition to different fee settings for each business partner, and there is a problem that convenience for the user is reduced. This problem is the same in the case where it is desired to perform charging in a situation where the added value of point services or the like is not limited to the power rate but varies with time.
Further, since a mechanism capable of not only charging but also discharging has been developed in recent electric vehicles, not only power trading at the time of charging but also power trading at the time of discharging must be considered.
In the conventional method of calculating the amount of electric power, the power on the power supply side is calculated based on the declaration of the amount of power received by the power receiving side, so if there is a false declaration, etc. There is a problem that it is not possible to monitor and manage them from a fair standpoint.

  The main object of the present invention is to solve the above-described problems, and it is a main object of the present invention to realize an energy transaction management apparatus that improves user convenience.

The energy transaction management device according to the present invention is:
Energy transaction management that manages energy transactions between a transaction request device that has an energy storage mechanism and requests energy transactions and a transaction response device that responds to energy transaction requests when conditions are met A device,
A storage amount-specific condition information storage unit that stores a storage amount-specific condition information in which a plurality of energy storage amount levels are defined, and a storage amount-specific price range is defined as an energy transaction price range for each energy storage amount level;
A condition information storage unit by time zone that stores condition information by time zone in which a plurality of time zones are defined and a price zone by time zone is defined as a transaction price zone of energy for each time zone;
An information input unit for inputting a request time when the transaction requesting device requests an energy transaction, and a value of an energy storage amount of the transaction requesting device at the requesting time;
From the time zone condition information, a time zone condition information extraction unit that extracts a time zone price zone paired with a time zone corresponding to the request time;
In the accumulation amount condition information, the energy accumulation amount level matches the value of the energy accumulation amount of the transaction requesting device input by the information input unit, and the accumulation amount price range is the time period condition information extraction unit. A search unit that searches for a pair of energy storage amount level and storage amount price range that matches the time zone price range extracted by
When the search unit searches for a pair of energy storage amount level and storage amount-specific price range, the transaction request device is notified that a condition has been established between the transaction request device and the transaction response device. And a notification unit.

  Since the energy transaction management device according to the present invention extracts the price based on the time when the user conducts the transaction, for example, in the energy transaction in which the price fluctuates depending on the time zone, the convenience of the user can be improved. is there.

(Explanation of charge / discharge control system operation)
Next, the operation of the charge / discharge control system will be described.
Charging / discharging may be performed between electric vehicles. That is, the charging / discharging equipment 100 and the charging / discharging equipment 200 may be electric vehicles. However, the charging / discharging equipment 100 is a charging / discharging stand 1000 and the charging / discharging equipment 200 is an electric car 2000 hereinafter. To proceed.
In the drawing, the charging / discharging stand 1000 is also referred to as “ES (Electric Stand)”, and the electric vehicle 2000 is also referred to as “EV (Electric Vehicle)”.

(Preparation of setting information)
FIG. 2 is a diagram illustrating an example of the charge / discharge transaction condition information 421.
FIG. 3 is a diagram illustrating an example of the power transaction value information 423.
First, preparation of information stored in the information storage unit 320 will be described.
For example, the owner of the electric vehicle 2000 generates the charge / discharge transaction condition information 421 shown in FIG. 2 using a terminal such as the in-vehicle mechanism 260, a mobile phone, or a personal computer. The setting information input unit 340 of the center device 300 inputs the generated charge / discharge transaction condition information 421 from the terminal or the like via the network 900 and the communication unit 180c. The charge / discharge condition information storage unit 321 stores the charge / discharge transaction condition information 421 input by the setting information input unit 340.

  Further, for example, the owner of the charge / discharge station 1000 generates the power transaction value information 423 shown in FIG. 3 using a terminal such as a mobile phone or a personal computer. The setting information input unit 340 of the center apparatus 300 inputs the generated power transaction value information 423 from the terminal or the like via the network 900 and the communication unit 180c. The power transaction value storage unit 323 stores the power transaction value information 423 input by the setting information input unit 340.

As shown in FIG. 2, the charge / discharge transaction condition information 421 includes a charge / discharge facility ID (that is, an ID of the electric vehicle 2000), a type of charge / discharge, a remaining power level of the electric vehicle 2000, and a transaction condition for performing the transaction. It is.
Here, in the charge / discharge transaction condition information 421, a remaining power level (that is, an energy storage amount level) of a plurality of electric vehicles 2000 is defined. In the charge / discharge transaction condition information 421, transaction conditions (that is, a price range for each energy storage amount level as an energy transaction price range) are defined. Therefore, the charge / discharge transaction condition information 421 is an example of accumulation amount condition information.

Furthermore, the charge / discharge transaction condition information 421 includes the remaining power level (energy accumulation level) when the electric vehicle 2000 receives energy (that is, when charging) as an energy transaction, and the electric vehicle 2000 as an energy transaction. , A remaining power level (energy accumulation level) when energy is supplied (that is, when discharging) is defined.
In the description of the present embodiment, the remaining power level indicates the ratio (%) of the remaining power to the full capacity. (Here, the full amount is the amount of electricity stored when 100% of electricity is stored in the electricity storage mechanism.) However, the remaining electricity level may be defined by an absolute value (for example, “50 khw etc.”).

In FIG. 2, as an example of the electric vehicle 2000, only “EV001” is illustrated and other IDs are omitted, but the charge / discharge transaction condition information 421 includes other IDs (for example, “EV002”). And the like). That is, the charge / discharge condition information storage unit 321 stores the charge / discharge transaction condition information 421 in association with the identifier (ID) of the electric vehicle 2000 for each electric vehicle 2000 as shown in FIG.
Further, illustration of records having a remaining power level of 80% or more and description in the following specific examples are omitted.

As shown in FIG. 3, the power transaction value information 423 includes a charge / discharge facility ID (that is, the ID of the charge / discharge station 1000), a time zone, and a transaction value (sell price, buy price).
Here, in the power transaction value information 423, a plurality of time zones are defined, and a transaction value (that is, a price zone by time zone as an energy transaction price zone for each time zone) is defined. Therefore, the power transaction value information 423 is an example of time zone condition information.

In FIG. 3, only “ES500” is illustrated as an example of the charging / discharging stand 1000 and other IDs are omitted, but the power transaction value information 423 includes other IDs (for example, “ES600”). And the like). That is, the power transaction value storage unit 323 stores the power transaction value information 423 in association with the identifier (ID) of the charge / discharge station 1000 for each charge / discharge station 1000 as shown in FIG.
Here, the time zone may be defined for each date as shown in FIG. 3, and the date information may not be included. In the following description of specific examples, it is assumed that the transaction value does not vary depending on the date, and in particular, date information is omitted.

  In the example of the charge / discharge transaction condition information 421 in FIG. 2, the transaction condition is defined as a price range having a predetermined range, and in the example of the power transaction value information 423 in FIG. 3, the transaction value indicates a predetermined value. It is defined as a price. However, the transaction condition of the charge / discharge transaction condition information 421 may be a price indicating a predetermined value, and the transaction value of the power transaction value information 423 may be a price range having a predetermined range. Moreover, the price range in which the transaction conditions of the charge / discharge transaction condition information 421 and the transaction values of the power transaction value information 423 have a predetermined range may be used, or conversely, the transaction conditions and the power transaction value information of the charge / discharge transaction condition information 421. The transaction value 423 may be a price indicating a predetermined value.

(ID authentication)
FIG. 4 is a flowchart showing the charge / discharge transaction process.
Next, the charge / discharge transaction process will be described.
First, the charging / discharging stand 1000 (ES) and the electric vehicle 2000 (EV) connect each other and exchange each other's ID (S401 in FIG. 4).

Specifically, for example, the owner of the electric vehicle 2000 connects the connection unit 130b to the connection unit 130a of the charge / discharge stand 1000.
The connection management unit 115b of the electric vehicle 2000 acquires the ID of the electric vehicle 2000 stored in the charge / discharge facility ID storage unit 112b, and the connection unit 130b charges the ID of the electric vehicle 2000 acquired by the connection management unit 115b. It transmits to the connection part 130a of the discharge stand 1000. And the connection management part 115a of the charging / discharging stand 1000 acquires ID of the electric vehicle 2000 which the connection part 130a received.
When acquiring the ID of the electric vehicle 2000, the connection management unit 115a of the charge / discharge stand 1000 acquires the ID of the charge / discharge stand 1000 stored in the charge / discharge facility ID storage unit 112a. And the connection management part 115b of the electric vehicle 2000 acquires ID of the charging / discharging stand 1000 by the path | route reverse to the above.
For example, the ID of the electric vehicle 2000 may be an ID that can be identified by the charging / discharging stand 1000 or the center device 300, and a vehicle number, personal information of an ETC (registered trademark) card, or the like may be used.

  Then, the charging / discharging stand 1000 and the electric vehicle 2000 transmit the ID to the center device 300 (S402 in FIG. 4). That is, the center apparatus 300 is inquired whether the charge / discharge stand 1000 and the electric vehicle 2000 are chargeable / dischargeable transactions.

Specifically, the communication unit 180b of the electric vehicle 2000 transmits the ID of the charging / discharging stand 1000 acquired by the connection management unit 115b and the ID of the electric vehicle 2000 as an inquiry to the center device 300 via the network 900. To do. Here, information transmitted from the charging / discharging stand 1000 and the electric vehicle 2000 to the center apparatus 300 in order to obtain a determination regarding the transaction is referred to as “inquiry”.
Similarly, specifically, the communication unit 180a of the charging / discharging stand 1000 uses the ID of the electric vehicle 2000 and the ID of the charging / discharging stand 1000 acquired by the connection management unit 115a as inquiries, and transmits the center via the network 900. To device 300.

  And the authentication inquiry information storage part 322 of the center apparatus 300 is constant about the inquiry (ID of the charging / discharging stand 1000 and ID of the electric car 2000) transmitted from the communication part 180b of the electric car 2000 via the communication part 180c. Remember time. Similarly, the authentication inquiry information storage unit 322 stores the inquiry (the ID of the electric vehicle 2000 and the ID of the charge / discharge stand 1000) transmitted from the communication unit 180a of the charge / discharge stand 1000 for a certain period of time.

  In response to a new inquiry, the connection authentication unit 331, when the authentication inquiry information storage unit 322 already stores an inquiry in which the IDs of the charge / discharge stand 1000 and the electric vehicle 2000 match, It authenticates that the electric vehicle 2000 can be traded. Then, the communication unit 180c authenticates that the charging / discharging stand 1000 and the electric vehicle 2000 can be traded with the transmission destination of the new inquiry and the transmission destination of the inquiry stored in the authentication inquiry information storage unit 322. Information indicating that this has been done is transmitted (S403 in FIG. 4).

  For example, if the inquiry (the ID of the charge / discharge stand 1000 and the ID of the electric vehicle 2000) is transmitted from the electric vehicle 2000 prior to the charge / discharge station 1000, the authentication inquiry information storage unit 322 stores the inquiry from the electric vehicle 2000. To do. Next, when an inquiry is transmitted from the charging / discharging stand 1000, the connection authentication unit 331 makes an inquiry from the electric vehicle 2000 stored in the authentication inquiry information storage unit 322 and an inquiry from the new charging / discharging stand 1000. Compare. Then, if the IDs of the charging / discharging stand 1000 and the ID of the electric vehicle 2000 that are the same match each other, the connection authentication unit 331 authenticates that the charging / discharging stand 1000 and the electric vehicle 2000 can be traded.

Here, if there is no matching inquiry for a certain time, the connection authentication unit 331 does not perform authentication.
In addition, the authentication inquiry information storage unit 322 stores in advance IDs of an unauthorized charging / discharging stand 1000 that is not permitted to be connected and an electric vehicle 2000 (for example, a stolen electric vehicle 2000). Even when the ID is included in the inquiry, the connection authentication unit 331 does not perform authentication.
When the authentication is not performed, the communication unit 180c transmits information indicating that the authentication cannot be performed to one or both of the inquiry transmission destinations. The authentication inquiry information storage unit 322 discards the stored inquiry.
If the center device 300 does not authenticate, the connection management unit 115a of the charging / discharging stand 1000 and the connection management unit 115b of the electric vehicle 2000 prohibit charging / discharging transactions with the connection partner until the next authentication inquiry is successful. (“No” in S403 in FIG. 4).
On the other hand, if the center apparatus 300 authenticates, the process proceeds to the next process (“Yes” in S403 in FIG. 4).

(Establishment of transaction conditions)
In S404 to S407 of FIG. 4, the center apparatus 300 determines whether or not the mutual transaction conditions between the charge / discharge stand 1000 and the electric vehicle 2000 are satisfied.
Note that there are two examples of the determination method for establishing the transaction condition, for example. First, a first example will be described.

(First example of transaction condition establishment determination)
First, the charge / discharge control mechanism 120b of the electric vehicle 2000 acquires the remaining power amount of the power storage mechanism 150b. Here, the remaining power amount corresponds to the energy storage amount.
Then, the communication unit 180b sends the inquiry about the ID of the electric vehicle 2000, the remaining power of the power storage mechanism 150b, and the ID of the charge / discharge station 1000 of the connection partner to the center device 300 (S404 in FIG. 4).

At this time, the communication unit 180b can transmit the time information included in the inquiry. The time information may be a transmission time at which the communication unit 180b transmits an inquiry, or a time set by a user of the electric vehicle 2000 (for example, a time at which the user wants to charge / discharge the electric vehicle 2000). That is, this time can be said to be a request time when the electric vehicle 2000 requests a transaction.
In addition, the remaining power amount of the power storage mechanism 150b included in the inquiry is also the remaining power amount at a predetermined time or a predetermined date (for example, a time or date when the user wants to charge / discharge the electric vehicle 2000). The value estimated by the in-vehicle mechanism 260 may be used.

The setting information input unit 340, via the communication unit 180c, the ID of the electric vehicle 2000, the ID of the charging / discharging stand 1000 that the electric vehicle 2000 requests a transaction, and the request time that the electric vehicle 2000 requests an energy transaction. Then, the value of the remaining power amount of the electric vehicle 2000 at the requested time is input.
Note that the setting information input unit 340 may use the time indicated by the information included in the inquiry as the request time, or may use the time when the communication unit 180c receives the inquiry from the electric vehicle 2000 as the request time. The time when the unit 340 performs input may be set as the request time.
Here, the setting information input unit 340 will be described assuming that the time when the communication unit 180c receives an inquiry from the electric vehicle 2000 is input as the request time.

Then, transaction agent unit 332 refers to charge / discharge transaction condition information 421 and electric vehicle 2000 receives (charges) energy based on the remaining power level that matches the value of the remaining power input by setting information input unit 340. Or the type of transaction to supply (discharge) energy is determined (S405 in FIG. 4).
Here, transaction surrogate unit 332 refers to charge / discharge transaction condition information 421 corresponding to the ID of electric vehicle 2000 input by setting information input unit 340.

Further, the transaction agent unit 332 searches the charge / discharge transaction condition information 421 shown in FIG. 2 for a remaining power level that matches the value of the remaining power of the electric vehicle 2000 input by the setting information input unit 340.
Here, transaction surrogate unit 332 searches charge / discharge transaction condition information 421 corresponding to the ID of electric vehicle 2000 input by setting information input unit 340.

Then, the transaction agent unit 332 extracts transaction conditions corresponding to the searched remaining power level (S405 in FIG. 4).
The contents described in parentheses in S405 of FIG. 4 will be described in a second example of determination of establishment of transaction conditions described later.

Two specific examples will be described.
First, as a first specific example, for example, when the ID of the electric vehicle 2000 is “EV001” and the remaining power amount is 5%, this corresponds to D501 in FIG. It is determined that it is “charge”, and the transaction condition “100 yen / khw or less” is extracted.
Alternatively, as a second specific example, for example, when the ID of the electric vehicle 2000 is “EV001” and the remaining power amount is 75%, this corresponds to D505 in FIG. It is determined that it is “discharge”, and the transaction condition “20 yen / khw or more” is extracted.

Next, the transaction agent unit 332 extracts from the power transaction value information 423 a transaction value that is paired with a time zone corresponding to the requested time.
Here, the transaction agent unit 332 obtains the transaction value paired with the time zone corresponding to the requested time from the power transaction value information 423 corresponding to the ID of the charge / discharge station 1000 input by the setting information input unit 340. Extract (S406 in FIG. 4).
The contents described in parentheses in S406 of FIG. 4 will be described in a second example of determination of establishment of transaction conditions described later.

A specific example will be described.
Assuming that the request time of the first specific example is “7: 00: 00: 00”, the transaction agent unit 332 sets the transaction value (sell price) “30 yen / khw” and the transaction value (buy price) “10 yen / khw”. Extract.
Also, assuming that the request time of the second specific example is “12:00:00”, the transaction agent unit 332 extracts the transaction value (sell price) “impossible” and the transaction value (buy price) “50 yen / khw”. .
Here, “impossible” means that the charging / discharging stand 1000 does not perform a transaction during the corresponding time zone.

  Then, the transaction agent unit 332 determines whether or not the transaction condition extracted in S405 matches the transaction value extracted in S406. That is, it is determined whether or not the transaction conditions between the charging / discharging stand 1000 and the electric vehicle 2000 match (S407 in FIG. 4).

When it is determined that the transaction conditions are met, the communication unit 180c notifies the electric vehicle 2000 via the network 900 that the condition is established between the charge / discharge station 1000 and the electric vehicle 2000.
That is, when it is determined that the transaction conditions are met, the communication unit 180c notifies the inquiry from the electric vehicle 2000 that the transaction conditions have been established.
When it is determined that the transaction conditions are met, the communication unit 180c may notify the inquiry from the charge / discharge station 1000 that the transaction conditions have been established.

At this time, the communication unit 180c transmits information on the established transaction conditions and transaction values to the electric vehicle 2000.
And the charging / discharging control information storage part 111b of the electric vehicle 2000 memorize | stores the information of the established transaction conditions and transaction value.
On the other hand, when the transaction condition does not match, the communication unit 180c notifies the inquiry from the electric vehicle 2000 that the condition is not satisfied.
Note that, when the transaction conditions do not match, the communication unit 180c may notify the inquiry from the charging / discharging stand 1000 that the condition is not satisfied.

A specific example will be described.
The transaction condition of the first specific example is “100 yen / khw or less” and the type is “charge”. Therefore, the transaction agency 332 compares the transaction value (sale price) “30 yen / khw” with the transaction condition “100 yen / khw or less” and determines that the transaction value (sell price) matches the transaction condition (FIG. 4). S407 “Yes”).
The transaction condition of the second specific example is “20 yen / khw or more” and the type is “discharge”. Therefore, the transaction agent 332 compares the transaction value (buy price) “50 yen / khw” with the transaction condition “20 yen / khw or more” and determines that the transaction value (buy price) matches the transaction condition (FIG. 4). S407 “Yes”).

On the other hand, when the transaction conditions of the charging / discharging stand 1000 and the electric vehicle 2000 do not match, the electric vehicle 2000 makes an inquiry again after a predetermined time (“No” in S407 in FIG. 4). There may be a case where the transaction value is changed and it is determined that the transaction condition is met by the time until the inquiry is made again.
Here, the number of inquiries may be set in advance. If the transaction conditions between the charging / discharging stand 1000 and the electric vehicle 2000 do not match even if the number of inquiries is exceeded, the center device 300 searches for another charging / discharging stand 1000 by a method described later, and the electric vehicle 2000 can be notified.

  Moreover, it is also possible to set priorities in transaction conditions in advance, and when there are a plurality of conditions that match between the charge / discharge station 1000 and the electric vehicle 2000, the electric vehicle 2000 sets the transaction conditions with higher priority. It is possible to conduct transactions with priority.

(Second example of transaction condition establishment determination)
Next, the 2nd example of transaction condition establishment determination is demonstrated.
The process in S404 of FIG. 4 is the same as the first example of the transaction condition establishment determination.
And the transaction agent part 332 extracts the transaction value paired with the time slot | zone corresponding to a request | requirement time from the electric power transaction value information 423 (the bracket | parenthesis writing of S405 of FIG. 4).
Here, the transaction agent unit 332 obtains the transaction value paired with the time zone corresponding to the requested time from the power transaction value information 423 corresponding to the ID of the charge / discharge station 1000 input by the setting information input unit 340. Extract.

Next, transaction agent unit 332 refers to charge / discharge transaction condition information 421, and electric vehicle 2000 receives energy (charges) based on the remaining power level that matches the value of remaining power input by setting information input unit 340. ) Or energy supply (discharge) is determined (in parentheses in S406 in FIG. 4).
Here, transaction surrogate unit 332 refers to charge / discharge transaction condition information 421 corresponding to the ID of electric vehicle 2000 input by setting information input unit 340.

Furthermore, the transaction agent unit 332 searches the charge / discharge transaction condition information 421 shown in FIG. 2 for a transaction condition corresponding to the determined type and matching the transaction value extracted by the transaction agent unit 332 (FIG. 4 in S406).
Here, transaction surrogate unit 332 searches charge / discharge transaction condition information 421 corresponding to the ID of electric vehicle 2000 input by setting information input unit 340.

  Then, the transaction agent unit 332 determines whether or not the remaining power level paired with the searched transaction condition matches the value of the remaining power input by the setting information input unit 340 (FIG. 4). S407).

A specific example will be described.
The request time of the first specific example is “7: 00: 00: 00”. Therefore, the transaction agent 332 refers to the power transaction value information 423 in FIG. 3 and extracts the transaction value (sell price) “30 yen / khw” and the transaction value (buy price) “10 yen / khw” (FIG. 4). In S405).
Then, based on the remaining power “5%” of the electric vehicle 2000 of the first specific example, the transaction agent unit 332 refers to the charge / discharge transaction condition information 421 of FIG. 2 and determines that the type is “charge”. (In parentheses in S406 in FIG. 4).
Further, the transaction agent unit 332 refers to the charge / discharge transaction condition information 421 in FIG. 2 and sets “100 yen / khw” as the transaction condition of the type “Charge” and the transaction value (sale price) “30 yen / khw”. Search for “less than khw” (D501) and “less than 50 yen / khw” (D502) (in parentheses in S406 in FIG. 4).
Then, the transaction agent unit 332 includes the remaining power level paired with the transaction condition “less than 10%” (D501) and “less than 10% to less than 30%” (D502) in the first specific example. It is determined whether or not the remaining electric power amount of the electric vehicle 2000 matches “5%” (S407 in FIG. 4).
In the case of the first specific example, the transaction agent unit 332 determines that the remaining power level “less than 10%” matches the remaining power level “5%” (“Yes” in S407 in FIG. 4).

The request time of the second specific example is “12:00:00”. Therefore, the transaction agent 332 refers to the power transaction value information 423 in FIG. 3 and extracts the transaction value (sell price) “impossible” and the transaction value (buy price) “50 yen / khw” (in S405 of FIG. 4). Parentheses).
Then, based on the remaining power “75%” of the electric vehicle 2000 of the second specific example, the transaction agent unit 332 refers to the charge / discharge transaction condition information 421 of FIG. 2 and determines that the type is “discharge”. (In parentheses in S406 in FIG. 4).
Further, the transaction agent unit 332 refers to the charge / discharge transaction condition information 421 in FIG. 2, and the transaction condition “30 yen / khw” with the type “discharge” and the transaction value (buy price) “50 yen / khw”. Search for “more than khw” (D504) and “more than 20 yen / khw” (D505) (in parentheses in S406 in FIG. 4).
Then, the transaction agent unit 332 has the remaining power level paired with the transaction conditions “50% to less than 70%” (D504) and “70% to less than 80%” (D505). It is determined whether or not the remaining power amount “75%” of the electric vehicle 2000 of the specific example is matched (S407 in FIG. 4).
In the case of the second specific example, the transaction agent unit 332 determines that the remaining power level “70% to less than 80%” matches the remaining power level “75%” (“Yes” in S407 in FIG. 4).

As mentioned above, although the 1st example of transaction condition establishment determination and the 2nd example of transaction condition establishment determination were performed, both differ only in the order of processing, and transaction surrogate part 332 is substantially the same. Based on the same determination, the transaction condition establishment determination is performed.
That is, the transaction agent unit 332 matches the value of the remaining electric energy of the electric vehicle 2000 input by the setting information input unit 340 in the charge / discharge transaction condition information 421, and the transaction condition is determined by the transaction agent unit 332. A set of remaining power level and transaction conditions that match the extracted transaction value is searched. Then, the transaction agent unit 332 determines whether or not a combination of the remaining power level and transaction conditions has been searched.

A specific example will be described.
In the first specific example, the transaction surrogate unit 332 refers to the charge / discharge transaction condition information 421 in FIG. 2 and “less than 10%” as the remaining power level that matches the remaining power amount “5%” of the electric vehicle 2000. Search for. Then, the transaction agency 332 searches for “100 yen / khw or less” (D501) and “50 yen / khw or less” (D502) as transaction conditions that match the transaction value (selling price) “30 yen / khw”. To do. Then, the transaction agent unit 332 determines that the remaining power level “less than 10%” and the transaction condition “100 yen / khw or less” defined as a set in the charge / discharge transaction condition information 421 are retrieved.

  In the second specific example, the transaction surrogate unit 332 refers to the charge / discharge transaction condition information 421 in FIG. 2, and sets “70 to 80” as the remaining power level that matches the remaining power “75%” of the electric vehicle 2000. Search for less than%. Then, the transaction agent unit 332 searches for “30 yen / khw or more” (D504) and “20 yen / khw or more” (D505) as transaction conditions that match the transaction value (buy price) “50 yen / khw”. To do. Then, the transaction agent unit 332 determines that the remaining power level “70 to less than 80%” defined as a set in the charge / discharge transaction condition information 421 and the transaction condition “20 yen / khw or more” have been searched.

(Calculation of transaction volume)
When the transaction is established, transaction agency 332 calculates the transaction amount between electric vehicle 2000 and charge / discharge station 1000 (S408 in FIG. 4).

For example, it is assumed that the transaction agency 332 determines that the electric vehicle 2000 receives (charges) energy in the processing of S404 to S407 in FIG. 4 and searches for a combination of the remaining power level and transaction conditions.
In that case, transaction surrogate unit 332 is based on the remaining power level searched by transaction surrogate unit 332 among the remaining power levels when electric vehicle 2000 receives (charges) energy in charge / discharge transaction condition information 421. The remaining power level that is paired with the transaction condition that matches the transaction value extracted by the transaction proxy unit 332 is searched from among the remaining power levels that are greater than.
Then, when the corresponding remaining power level is searched, the transaction agent unit 332 determines the upper limit value of the maximum remaining power level among the searched remaining power levels and the remaining power input by the setting information input unit 340. The amount of energy (charge amount) received by the electric vehicle 2000 from the charge / discharge stand 1000 is determined using the difference from the value of.
Then, the transaction surrogate unit 332, when the corresponding remaining power level is not searched, the upper limit value in the remaining power level searched by the transaction proxy unit 332 and the value of the remaining power input by the setting information input unit 340 Is used to determine the amount of energy (charge amount) that the electric vehicle 2000 receives from the charge / discharge station 1000.

The first specific example will be described.
In the first specific example, the transaction agent unit 332 determines that the electric vehicle 2000 receives (charges) energy in the processes of S404 to S407 in FIG. 4, and the remaining power level is “less than 10%” and the transaction conditions. A set of “100 yen / khw or less” is searched.
And the transaction surrogate unit 332 has a remaining power level “less than 10% to less than 30%” higher than the searched remaining power level “less than 10%” (D501 in FIG. 2) among the remaining power levels in the case of charging ( D502) and “30% to less than 50%” (D503) are searched for a remaining power level that is paired with a transaction condition (sales price) “30 yen / khw”. Here, “50 yen / khw or less” (D502) matches the transaction value (sell price) “30 yen / khw”, but “20 yen / khw or less” (D503) is the transaction value (sell price) “30”. Does not match "yen / khw".
Therefore, the transaction agent unit 332 searches for the remaining power level “10% to less than 30%” (D502).

Then, since the corresponding remaining power level has been searched, the transaction agency 332 searches for the upper limit value “30%” in the maximum remaining power level “10% to less than 30%” (D502) among the searched remaining power levels. And “25%”, which is the difference between the remaining power amount of electric vehicle 2000 and “5%”, is determined as the amount of charge that electric vehicle 2000 receives from charging / discharging stand 1000.
Here, although the remaining power level is defined as “less than 30%”, the transaction agent unit 332 determines that the upper limit value indicated by the remaining power level is “30%” when calculating the transaction amount. .

  That is, in the first specific example, the transaction agent unit 332 refers to the charge / discharge transaction condition information 421, and “100 yen / khw or less” as a transaction condition that matches the transaction value (sale price) “30 yen / khw”. "(D501)" and "50 yen / khw or less" (D502). Then, the transaction agent unit 332 sets the remaining power level “less than 10%” (D501) and “less than 10% to less than 30%” (D502) paired with the transaction condition, which is the upper limit value “30%”. It can also be said that “25%”, which is the difference from the remaining power amount “5%” of the electric vehicle 2000, is calculated as the transaction amount.

For example, assuming that the transaction condition paired with the remaining power level “30% to less than 50%” (D503) matches the transaction value (selling price), the remaining power level “30% to less than 50%” Assume that (D503) and “10% to less than 30%” (D502) are searched as corresponding remaining power levels.
In this case, the transaction agent 332 determines that the maximum remaining power level among the searched remaining power levels is “30% to less than 50%” (D503), and “30% to less than 50%”. “45%”, which is the difference between the upper limit value “50%” and the remaining power amount “5%” of the electric vehicle 2000, is determined as the charge amount that the electric vehicle 2000 receives from the charging / discharging stand 1000.

  In addition, when the corresponding remaining power level is not searched, the transaction agent unit 332 obtains the upper limit value “10%” in the searched remaining power level “less than 10%” in the processing of S404 to S407 in FIG. “5%”, which is a difference from the remaining power amount “5%” of the electric vehicle 2000, is determined as the charge amount that the electric vehicle 2000 receives from the charge / discharge station 1000.

In addition, the following method may be sufficient as the process of calculation of the transaction amount of charge.
In the first specific example, the transaction agent unit 332 searches for a set of the remaining power level “less than 10%” and the transaction condition “100 yen / khw or less”. Then, the transaction agent 332 charges the electric vehicle 2000 from the charging / discharging stand 1000 to “5%”, which is the difference between the remaining electric power amount “5%” of the electric vehicle 2000 and the upper limit value “10%” indicated by the remaining electric power level. Calculated as transaction volume Here, although the remaining power level is defined as “less than 10%”, the transaction agent unit 332 determines that the upper limit value indicated by the remaining power level is “10%” when calculating the transaction amount. .

Furthermore, when the transaction for the calculated transaction amount is completed, the transaction agent unit 332 determines whether an additional transaction is established, and calculates the additional transaction amount when the transaction is established.
That is, when the calculated transaction amount “5%” is charged, the remaining power amount of the electric vehicle 2000 after the transaction is “10%”.
And although illustration is abbreviate | omitted, the transaction surrogate part 332 performs the process similar to S405-S407 of FIG. 4 inside S408, and determines whether a transaction is materialized, when remaining power is "10%". To do. In this case, the request time used in the processing of S404 to S407 in FIG.

  Transaction agent 332 searches for “10% to less than 30%” (D502) as the matching remaining power level, assuming that the remaining power of electric vehicle 2000 is “10%” after the transaction. Then, the transaction agency 332 searches for “100 yen / khw or less” (D501) and “50 yen / khw or less” (D502) as transaction conditions that match the transaction value (selling price) “30 yen / khw”. To do. Then, the transaction agent 332 searches for the remaining power level “10% to less than 30%” defined as a set in the charge / discharge transaction condition information 421 and the transaction condition “50 yen / khw or less” (D502). judge.

Then, the transaction agent unit 332 charges the electric vehicle 2000 from the charging / discharging stand 1000 with “20%”, which is the difference between the remaining power amount “10%” of the electric vehicle 2000 and the upper limit value “30%” indicated by the remaining power level. Calculated as transaction volume
That is, by summing up the transaction amount “5%” described above, the transaction agent 332 calculates “25%” as the transaction amount that the electric vehicle 2000 charges from the charge / discharge station 1000.

  Transaction agency 332 repeats the same processing in S408 of FIG. However, in the first specific example, when the remaining power amount of the electric vehicle 2000 becomes “30%”, the transaction conditions corresponding to the remaining power level “30% to less than 50%” (D503) in FIG. “20 yen / khw or less” does not match the transaction value (selling price) “30 yen / khw”. Therefore, the transaction agent unit 332 calculates “25%” described above as the final value of the transaction amount that the electric vehicle 2000 charges from the charge / discharge station 1000.

By the method described above, the transaction agent unit 332 calculates “25%” as the final value of the transaction amount that the electric vehicle 2000 charges from the charge / discharge station 1000.
Here, when the electric vehicle 2000 transmits an inquiry to the center device 300, the electric vehicle 2000 transmits together with the full information of the power storage mechanism 150b of the electric vehicle 2000. Furthermore, the information storage unit 320 of the center apparatus 300 can store information on the full capacity of the power storage mechanism 150b in advance in association with the ID of the electric vehicle 2000.
For example, assuming that the full capacity of the power storage mechanism 150b of the electric vehicle 2000 is “1000 khw”, the transaction agent unit 332 calculates “1000 khw × 25% × 30 yen = 7500 yen” as the amount to be charged. To do.
Here, the amount to be charged is, for example, an amount paid by the user of the electric vehicle 2000 to the owner of the charge / discharge station 1000, for example.

  The same applies to the processing when the electric vehicle 2000 is discharged to the charge / discharge stand 1000.

For example, it is assumed that the transaction agent 332 determines that the electric vehicle 2000 supplies (discharges) energy in the processing of S404 to S407 in FIG. 4 and searches for a combination of the remaining power level and transaction conditions.
In that case, transaction surrogate unit 332 uses the remaining power level searched by transaction surrogate unit 332 among the remaining power levels when electric vehicle 2000 supplies (discharges) energy in charge / discharge transaction condition information 421. The remaining power level that is paired with the transaction condition that matches the transaction value extracted by the transaction agency 332 is searched from among the remaining remaining power levels.
Then, when the corresponding remaining power level is searched, the transaction agency 332 searches for the lower limit value of the minimum remaining power level among the searched remaining power levels and the remaining power input by the setting information input unit 340. The amount of energy (discharge amount) that the electric vehicle 2000 supplies to the charging / discharging stand 1000 is determined using the difference from the above value.
Then, the transaction surrogate unit 332, when the corresponding remaining power level is not searched, the lower limit value in the remaining power level searched by the transaction proxy unit 332 and the value of the remaining power input by the setting information input unit 340 Is used to determine the amount of energy (discharge amount) that the electric vehicle 2000 supplies to the charging / discharging stand 1000.

The second specific example will be described.
In the second specific example, the transaction agent unit 332 determines that the electric vehicle 2000 supplies (discharges) energy in the processing of S404 to S407 in FIG. 4, and the remaining power level “70% to less than 80%”. And a search condition of “20 yen / khw or more”.
Then, the transaction agent unit 332 determines the transaction value from the remaining power levels that are smaller than the searched remaining power level “70% to less than 80%” (D505 in FIG. 2) among the remaining power levels in the case of discharge. (Bid price) The remaining electric power level paired with the transaction condition matching “50 yen / khw” is searched.
Here, the remaining power level lower than the searched remaining power level “70% to less than 80%” (D505 in FIG. 2) is only “50% to less than 70%” (D504), and “30 yen / “More than khw” matches the transaction price (buy price) “50 yen / khw”.
Therefore, the transaction agent unit 332 searches for the remaining power level “50% to less than 70%” (D504).

  Then, since the corresponding remaining power level has been searched, the transaction agency 332 searches for the lower limit value “50%” in the minimum remaining power level “50% to less than 70%” (D504) among the searched remaining power levels. And “25%”, which is the difference between the remaining power amount of electric vehicle 2000 and “75%”, is determined as the amount of discharge that electric vehicle 2000 supplies to charging / discharging stand 1000.

  That is, in the second specific example, the transaction agent unit 332 refers to the charge / discharge transaction condition information 421, and “30 yen / khw or more as a transaction condition that matches the transaction value (buy price)“ 50 yen / khw ”. "(D504)" and "20 yen / khw or more" (D505). And the transaction agency 332 is a lower limit value among the remaining power level “50% to less than 70%” (D504) and “70% to less than 80%” (D505) paired with the transaction conditions. It can be said that “25%”, which is the difference between a certain “50%” and the remaining electric power amount “75%” of the electric vehicle 2000, is calculated as the transaction amount.

Note that the charge / discharge transaction condition information 421 shown in FIG. 2 does not exist, but, for example, the charge / discharge transaction condition information 421 has a definition of “discharge” as the type and a remaining power level “30% to less than 50%”. Suppose that the paired transaction conditions match the transaction value (buy price) “50 yen / khw”.
In this case, the transaction agent unit 332 performs a transaction from among the remaining power levels in the case of discharging, from among the remaining power levels smaller than the searched remaining power level “70% to less than 80%” (D505 in FIG. 2). The remaining power level “50% to less than 70%” and “30% to less than 50%” are searched as the remaining power level paired with the transaction condition matching the value (buy price) “50 yen / khw”. .
Then, the transaction agent unit 332 determines that the minimum remaining power level is “30% to less than 50%” among the searched remaining power levels, and sets the lower limit value “30% to less than 50%”. “45%”, which is the difference between “30%” and the remaining power amount “75%” of the electric vehicle 2000, is determined as the discharge amount that the electric vehicle 2000 supplies to the charging / discharging stand 1000.

  When the corresponding remaining power level is not searched, the transaction agent unit 332 performs the processing of S404 to S407 in FIG. 4 to set the lower limit “70%” in the searched remaining power level “70% to less than 80%”. And “5%”, which is the difference between the remaining power amount of electric vehicle 2000 and “75%”, is determined as the amount of discharge that electric vehicle 2000 supplies to charging / discharging stand 1000.

In addition, the following method may be sufficient as the process of calculation of the transaction amount of discharge.
In the second specific example, the transaction agent unit 332 searches for a set of a remaining power level “70 to less than 80%” and a transaction condition “20 yen / khw or more”. Then, the transaction agent unit 332 transfers “5%”, which is the difference between the remaining electric power “75%” of the electric vehicle 2000 and the lower limit “70%” indicated by the remaining electric power level, from the electric vehicle 2000 to the charge / discharge station 1000. Calculated as transaction volume to be discharged.

Furthermore, when the transaction for the calculated transaction amount is completed, the transaction agent unit 332 determines whether an additional transaction is established, and calculates the additional transaction amount when the transaction is established.
That is, when the calculated transaction amount “5%” is discharged, the remaining power amount of the electric vehicle 2000 after the transaction becomes “70%”.
And although illustration is abbreviate | omitted like the above-mentioned, the transaction surrogate part 332 carries out the process similar to S405-S407 of FIG. Go to and judge. In this case, the request time used in the processing of S404 to S407 in FIG.

  Transaction surrogate unit 332 searches for “50% to less than 70%” (D504) as the matching remaining power level, assuming that the remaining power of electric vehicle 2000 is “70%” after the transaction. Here, although the remaining power level is defined as “50% to less than 70%”, the transaction agent unit 332 sets the upper limit value indicated by the remaining power level to “70%” when calculating the transaction amount. Judge.

  Then, the transaction agent unit 332 searches for “30 yen / khw or more” (D504) and “20 yen / khw or more” (D505) as transaction conditions that match the transaction value (buy price) “50 yen / khw”. To do. And the transaction agency 332 searches for the remaining power level “50% to less than 70%” defined as a set in the charge / discharge transaction condition information 421 and the transaction condition “30 yen / khw or more” (D504). judge.

Then, the transaction agent 332 transfers “20%”, which is the difference between the remaining power “70%” of the electric vehicle 2000 and the lower limit “50%” indicated by the remaining power level, from the electric vehicle 2000 to the charge / discharge station 1000. Calculated as transaction volume to be discharged.
That is, by summing up the transaction amount “5%” described above, the transaction agent unit 332 calculates “25%” as the transaction amount discharged from the electric vehicle 2000 to the charge / discharge station 1000.

  Transaction agency 332 repeats the same processing in S408 of FIG. However, in the second specific example, when the remaining power amount of the electric vehicle 2000 becomes “50%”, the charge / discharge transaction condition information 421 in FIG. There are no applicable transaction conditions. Therefore, the transaction agent unit 332 calculates the aforementioned “25%” as the final value of the transaction amount that is discharged from the electric vehicle 2000 to the charge / discharge station 1000.

By the method described above, transaction agency 332 calculates “25%” as the final value of the transaction amount that electric vehicle 2000 discharges from electric vehicle 2000 to charge / discharge station 1000.
Here, when the electric vehicle 2000 transmits an inquiry to the center device 300, the electric vehicle 2000 transmits together with the full information of the power storage mechanism 150b of the electric vehicle 2000. Furthermore, the information storage unit 320 of the center apparatus 300 can store information on the full capacity of the power storage mechanism 150b in advance in association with the ID of the electric vehicle 2000.
For example, assuming that the full capacity of the power storage mechanism 150b of the electric vehicle 2000 is “1000 khw”, the transaction agency 332 calculates “1000 khw × 25% × 50 yen = 12,500 yen” as the amount to be charged. To do.
Here, the amount to be charged is, for example, the amount that the owner of the charge / discharge station 1000 pays to the user of the electric vehicle 2000, for example.

The communication unit 180c transmits the transaction amount calculated by the above processing to the electric vehicle 2000. Further, the communication unit 180c transmits the calculated amount of the transaction amount to the electric vehicle 2000.
Note that the electric vehicle 2000 may perform this transaction amount calculation process. Furthermore, the electric vehicle 2000 may perform the calculation process of the amount.

(Start of transaction)
The transaction process of the electric vehicle 2000 with the charge / discharge station 1000 (S409 in FIG. 4) will be described.
In the following description, the case where the electric vehicle 2000 charges from the charging / discharging stand 1000 will be described. When discharging from the electric vehicle 2000 to the charging / discharging stand 1000, only the relationship between charging and discharging is different and the description is omitted.

When the electric vehicle 2000 is charged from the charging / discharging stand 1000, the charge / discharge control unit 116b of the electric vehicle 2000 instructs the charge / discharge control mechanism 120b to prepare for charging and sets the charging standby state.
Then, the charge / discharge control unit 116b transmits a discharge request corresponding to the calculated transaction amount to the charge / discharge stand 1000 via the connection unit 130b in response to the charge / discharge control mechanism 120b being in the charge standby state. To do.
The charge / discharge control unit 116a of the charge / discharge stand 1000 receives a discharge request and selects a device for discharging from any of the power storage mechanism 150a, the power generation mechanism 160, and the supply / demand control unit 170. Then, the charge / discharge control unit 116a instructs the charge / discharge control mechanism 120a to discharge, and the charge / discharge control mechanism 120a starts discharging.
The charge / discharge control unit 116b of the electric vehicle 2000 transmits a transaction start notification to the transaction monitoring unit 333 of the center device 300 via the communication unit 180b along with the discharge start of the charge / discharge stand 1000.

(Transaction monitoring)
When the transaction is started, the transaction monitoring unit 333 monitors whether the transaction between the charge / discharge station 1000 and the electric vehicle 2000 is fraudulent (S410 in FIG. 4).
That is, when the communication unit 180c notifies that the condition is established between the electric vehicle 2000 and the charging / discharging stand 1000, and energy (electricity) is traded between the electric vehicle 2000 and the charging / discharging stand 1000. The transaction monitoring unit 333 monitors whether the transaction between the charge / discharge station 1000 and the electric vehicle 2000 is fraudulent.

  Specifically, the charge / discharge monitoring unit 117b of the electric vehicle 2000 measures the charge amount that has been traded with the charge / discharge stand 1000, and transmits the measured charge amount to the center apparatus 300 via the communication unit 180b. The charge / discharge monitoring unit 117a of the charge / discharge stand 1000 measures the amount of discharge that has been traded with the electric vehicle 2000, and transmits the measured amount of discharge to the center device 300 via the communication unit 180a.

  Then, the setting information input unit 340 of the center device 300 inputs the charge / discharge stand 1000 measured by the electric vehicle 2000 and the value of the amount of energy that has been traded (charge amount) from the electric vehicle 2000. In addition, the setting information input unit 340 inputs the value of the amount of energy (discharge amount) that has been traded with the electric vehicle 2000 and measured from the charge / discharge stand 1000 from the charge / discharge stand 1000.

  Here, the transaction monitoring unit 333 of the center apparatus 300 may periodically inquire about the amount of energy that has been traded to the electric vehicle 2000 and the charge / discharge station 1000.

Then, the transaction monitoring unit 333 receives the value of the amount of energy (charge amount) input from the electric vehicle 2000 by the setting information input unit 340 and the energy input from the charging / discharging stand 1000 by the setting information input unit 340. The amount (discharge amount) is compared.
Here, the power transaction record storage unit 324 stores the input charge / discharge value.

Then, as a result of the comparison by the transaction monitoring unit 333, the communication unit 180c has a value of the amount of energy (charge amount) input from the electric vehicle 2000 and a value of the amount of energy (discharge amount) input from the charge / discharge stand 1000. If the difference between the two is equal to or greater than the threshold value, the electric vehicle 2000 and the charge / discharge station 1000 are instructed to stop the energy transaction. That is, when the difference between the transaction amounts measured by the charge / discharge station 1000 and the electric vehicle 2000 is equal to or greater than the threshold value, the transaction monitoring unit 333 considers that there is fraud (“No” in S410 in FIG. 4).
When the center device 300 instructs to stop the transaction, the charge / discharge monitoring unit 117a of the charge / discharge stand 1000 and the charge / discharge monitoring unit 117b of the electric vehicle 2000 stop charging / discharging.
Here, the threshold value is stored in the information storage unit 320, for example.
The threshold value is stored in the information storage unit 320 as “50 khw”, for example. When the difference between the value of the charge amount input from the electric vehicle 2000 and the value of the energy amount (discharge amount) input from the charge / discharge stand 1000 is equal to or greater than “50 khw”, the transaction monitoring unit 333 Instruct to stop trading energy.

  On the other hand, when the difference between the transaction amounts measured by the charge / discharge station 1000 and the electric vehicle 2000 is less than the threshold, the transaction monitoring unit 333 considers that there is no fraud (“Yes” in S410 of FIG. 4). And the electric vehicle 2000 and the charging / discharging stand 1000 continue a transaction.

Then, the charge / discharge monitoring unit 117b of the electric vehicle 2000 acquires the charge amount from the charge / discharge control mechanism 120b and monitors whether or not the calculated transaction amount has been reached (S411 in FIG. 4). The monitoring result is reported to the center apparatus 300 via the communication unit 180b.
If the monitoring result does not reach the calculated transaction volume, the electric vehicle 2000 and the charge / discharge station 1000 continue the transaction (“No” in S411 in FIG. 4).
Here, the charge / discharge monitoring unit 117a of the charge / discharge stand 1000 may acquire the discharge amount from the charge / discharge control mechanism 120a and report it to the center apparatus 300.

As a result of monitoring by the charge / discharge monitoring unit 117b, when the amount of charge / discharge reaches the calculated transaction amount (“Yes” in S411 in FIG. 4), the charge / discharge monitoring unit 117b Instruct to stop charging. Then, the charge / discharge monitoring unit 117b transmits a discharge stop instruction to the charge / discharge stand 1000 through the connection unit 130b.
Here, as a result of monitoring by the charge / discharge monitoring unit 117a of the charge / discharge stand 1000, the charge / discharge monitoring unit 117a may instruct the charge / discharge control unit 116a to stop discharging. Then, the charge / discharge monitoring unit 117a may transmit a charge stop instruction to the charge / discharge stand 1000 through the connection unit 130a.

The charge / discharge control unit 116b of the electric vehicle 2000 receives the charge stop instruction, transmits the charge stop instruction to the charge / discharge control mechanism 120b, stops charging, and simultaneously acquires the final remaining power amount from the charge / discharge control mechanism 120b. .
Furthermore, the charge / discharge control unit 116b notifies the transaction monitoring unit 333 of the center device 300 of the transaction completion via the communication unit 180b, and transmits the acquired remaining power amount.

The charge / discharge control unit 116a of the charge / discharge stand 1000 receives a discharge stop instruction, transmits a charge stop instruction to the charge / discharge control mechanism 120a, stops charging, and simultaneously obtains a final discharge amount from the charge / discharge control mechanism 120a. To do.
Furthermore, the charge / discharge control unit 116a notifies the transaction monitoring unit 333 of the center device 300 of the completion of the transaction via the communication unit 180a and transmits the acquired discharge amount.

  The transaction monitoring unit 333 of the center device 300 receives transaction completion notifications from the charge / discharge control unit 116b of the electric vehicle 2000 and the charge / discharge control unit 116a of the charge / discharge stand 1000, and the transaction actual value that has been sequentially reported. Tally. The transaction monitoring unit 333 confirms that there is no difference between the counting result and the final charge / discharge amount, and the transaction has been completed normally. And the electric power transaction result memory | storage part 325 memorize | stores a final transaction result (S412 of FIG. 4).

(Search for charge / discharge stand 1000)
Here, based on the inquiry from the electric vehicle 2000, the center device 300 can also search for the charge / discharge station 1000 that meets the transaction conditions.

First, the communication unit 180b of the electric vehicle 2000 transmits the ID of the electric vehicle 2000, the remaining power amount of the power storage mechanism 150b, and the request time as an inquiry to the center device 300.
Here, the request time is a time when the electric vehicle 2000 schedules a transaction with the charge / discharge station 1000, and the remaining power amount of the power storage mechanism 150b is an estimated value of the remaining power amount at the request time.
In this case, the setting information input unit 340 of the center device 300 inputs the information included in the inquiry (the time when the electric vehicle 2000 schedules a transaction with the charge / discharge station 1000) as the request time.

  Then, similarly to the above, the transaction agent unit 332 of the center device 300 refers to the charge / discharge transaction condition information 421 corresponding to the ID of the electric vehicle 2000, and extracts the type and transaction condition that match the remaining power.

  Further, the transaction agent unit 332 sets the transaction value that matches the extracted type, the extracted transaction condition, and the request time from all the power transaction value information 423 stored in the power transaction value storage unit 323. The ID is extracted in association with the ID.

Here, for example, the information storage unit 320 stores, for each of the plurality of charge / discharge stations 1000, the attributes (name, location, etc.) of the charge / discharge station 1000 associated with the ID of the charge / discharge station 1000. I can do it.
And the transaction agent part 332 refers to the information of the information storage part 320, and acquires the attribute of the charging / discharging stand 1000 corresponding to the extracted transaction value.
And the communication part 180c can transmit the information of the transaction value which the transaction agency part 332 extracted, and the attribute of the charging / discharging stand 1000 with respect to the electric vehicle 2000 with which the inquiry was made.
