(embodiment)
[1. Mechanism for transferring environmental value together with electric power using electric vehicles]
In general, power derived from renewable energy sources such as solar power and wind power is said to have a low impact on the environment, such as not emitting carbon dioxide in order to generate power, in addition to the value of the power itself. It is considered to have environmental value. For example, environmental value is considered to have a monetary value proportional to the amount of electricity. Therefore, when power derived from renewable energy is transferred from one owner to another, the environmental value of the power derived from renewable energy also accompanies the transfer from one owner to another. will be transferred to The environmental value of power derived from renewable energy in this embodiment may be determined, for example, based on the market price of the environmental value at the time the power is transferred.

FIG. 1 is a diagram for explaining a mechanism for transferring environmental value together with electric power using an electric vehicle according to an embodiment. In FIG. 1, the user U supplies power derived from photovoltaic power generated by a home-use photovoltaic power generator (hereinafter also referred to as a generator PV) installed in the user U's house. Charge the electric vehicle EV. Note that the generator PV may be installed in a place other than the residence (for example, the garden of the user U's residence) as long as the generator PV is managed by the user U.

At this time, the information processing system 1 (see FIG. 3), which will be described later, determines the amount of charge derived from the power generated by the generator PV, out of the amount of charge that is the amount of power charged in the electric vehicle EV of the user U. The charging amount derived from photovoltaic generation is associated with information about the user U and registered in the blockchain. Also, the amount of charge derived from photovoltaic power generation is considered to have an environmental value equivalent to the amount of electric power. Therefore, the information processing system 1 associates the environmental value corresponding to the amount of charge derived from photovoltaic power generation with the information about the user U and registers it in the blockchain.

Also, the user U moves the electric vehicle EV to a manager's store (for example, a large shopping mall, etc.) managed by another user (hereinafter also referred to as manager) different from the user U. Subsequently, the user U discharges the electric power charged in the electric vehicle EV of the user U to the charging/discharging facility installed at the manager's store. Note that the charging/discharging equipment may be installed in a place other than the administrator's store (for example, a parking lot of the administrator's store) as long as the charging/discharging equipment is managed by an administrator.

At this time, the information processing system 1, which will be described later, determines the amount of electric power discharged from the electric vehicle EV to the charging/discharging equipment installed in the manager's store. is transferred from the user U to the administrator. In addition, the information processing system 1 provides incentives (for example, points that can be used at the manager's store) to the user U as compensation for transferring the environmental value equivalent to the discharge amount derived from photovoltaic power generation to the manager. Give. Incentives given to users are not limited to points, and may be, for example, coupons, discount coupons, awards for transferring environmental value, and the like. Further, incentives are not limited to those that can be used at the manager's store, and may be those that can be used at places other than the manager's store. In the following, as an example of the incentive given to the user, a case of points that can be used at the manager store will be described.

In the example shown in FIG. 1, by giving an incentive of points to the user U as compensation for discharge to the manager's store, the administrator can provide the user with power derived from renewable energy that cannot be completely consumed by the manager. It is possible to prompt the store to discharge. In addition, by giving points that can be used at the manager's store, it is possible to motivate the user to visit the manager's store and try to discharge.

Note that FIG. 1 illustrates the generator PV for photovoltaic power generation as an example of the renewable energy power generation facility managed by the user U, but the renewable energy power generation facility managed by the user U is for photovoltaic power generation. is not limited to the generator PV. Specifically, the renewable energy power generation facility managed by the user U is any power generation facility that generates power using renewable energy such as wind power generation, biomass power generation, hydroelectric power generation, and geothermal power generation. good too.

Also, in FIG. 1 , the user U's electric vehicle has been described as an example of the user's U mobile charging device, but the user's U mobile charging device is not limited to the electric vehicle. Specifically, user U's mobile charging device may be a portable battery. For example, the user U charges the user U's battery pack (an example of a portable battery) with power derived from photovoltaic power generated by a household photovoltaic power generator installed in the user U's house. do. Then, the user U may carry the charged battery pack to the administrator's store by bicycle or the like, and discharge the power charged in the battery pack to the charging/discharging facility installed at the administrator's store. Also, the user U's mobile charging device may be an electric vehicle other than an electric vehicle. For example, the mobile charging device of the user U may be an electric mobile body such as an electric motorcycle (for example, an electric bicycle or an electric motorcycle), an electric wheelchair, an electric kickboard, or an autonomous mobile robot. A case where the user U's mobile charging device is an electric vehicle EV will be described below.

[2. Method of managing environmental value transactions using blockchain technology]
FIG. 2 is a diagram for explaining a method of managing environmental value transactions using blockchain technology according to the embodiment. The information processing system 1 (see FIG. 3), which will be described later, measures the amount of charge of power derived from renewable energy (hereinafter also referred to as the amount of charge derived from renewable energy) and the amount of discharge of power derived from renewable energy (hereinafter referred to as regeneration (also called discharge amount derived from possible energy) is managed by a smart contract on the blockchain. A smart contract is a function that automatically executes the set requirements by writing a program on the blockchain. The renewable energy-derived charge amount and the renewable energy-derived discharge amount in this embodiment are expressed as tokens on the blockchain. For example, the information processing system 1 can implement a smart contract using an Ethereum token interface standard called ERC20 (Ethereum Request for Comments: Token Standard #20).

FIG. 2 will now be described in association with FIG. 2, a meter (hereinafter also referred to as the first meter) for measuring the amount of power generated by the generator PV shown in FIG. , also referred to as a second meter) holds an address (hereinafter also referred to as a first address) on the blockchain linked to the meter pair. Also, the user U shown in FIG. 1 holds an address on the blockchain linked to the user U (hereinafter also referred to as a second address). In addition, the administrator's store shown in FIG. 1 holds an address (hereinafter also referred to as a third address) on the block chain linked to the administrator. In addition, the renewable energy-derived charge amount (in the example shown in FIG. 1, the photovoltaic power generation-derived charge amount) and the renewable energy-derived discharge amount (in the example shown in FIG. 1, the photovoltaic power generation-derived discharge amount) are is held as a balance at the address of

In FIG. 2, when the user U's electric vehicle EV is charged with the amount of charge derived from solar power generation in FIG. do. Subsequently, the information processing system 1 registers the issued environmental value token and the amount of charge derived from photovoltaic power generation in the first address associated with the meter pair. Also, the first address associated with the meter pair is associated with the second address associated with the user U (see FIG. 6). That is, when the information processing system 1 registers the environmental value token and the solar power generation-derived charging amount at the first address, the environmental value token and the solar power generation-derived charging amount are automatically associated with the second address associated with the user U. is registered.

After that, in FIG. 1, when the amount of discharge derived from photovoltaic power generation is discharged from the electric vehicle EV to the charge/discharge facility installed at the manager's store, the information processing system 1 sends the first address associated with the meter pair and the user U Of the environmental value tokens registered at the associated second address, the environmental value token indicating the environmental value equivalent to the discharge amount derived from the photovoltaic power generation is transferred to the third address associated with the administrator. Subsequently, the information processing system 1 sends a token (hereinafter referred to as , also called an administrator token). Subsequently, when the administrator token is issued, the information processing system 1 transfers the issued administrator token from the third address associated with the administrator to the second address associated with the user U.

In the example shown in Figure 2, the environment value token issued to the first address linked to the meter pair by using the characteristic of the blockchain that "it is guaranteed that the balance of the token cannot be transferred twice." It is possible to guarantee that the amount of discharge exceeding the amount recorded as is not considered to be transferred to others as environmental value.

In FIG. 2, the case where the information processing system 1 manages information about the renewable energy-derived charge amount and the renewable energy-derived discharge amount using blockchain technology has been described. Information about the renewable energy-derived charge amount and the renewable energy-derived discharge amount may be managed using technologies other than the chain. For example, if the information processing system 1 is a technology that makes it difficult to falsify information about the renewable energy-derived charge amount and the renewable energy-derived discharge amount, the renewable energy-derived charge amount can be obtained using any technology other than blockchain. and information on the renewable energy-derived discharge amount may be managed. For example, the information processing system 1 stores information about the renewable energy-derived charge amount and the renewable energy-derived discharge amount in a predetermined storage area (for example, the storage unit 120 of the information processing device 100, an external database, etc.) other than the blockchain. may be recorded.

[3. Configuration example of information processing system]

The power generation gateway device 10 acquires power generation information regarding the amount of power generated by the power generator PV managed by the user U from the first meter. Further, when the power generation gateway device 10 acquires the power generation information, the power generation gateway device 10 notifies the information processing device 100 of the acquired power generation information. For example, the power generation gateway device 10 transmits the power generation information in each time period divided by predetermined time intervals (for example, every 30 minutes) to the information processing device 100 at predetermined time intervals.

The charging gateway device 20 acquires charging information regarding the amount of charge in the electric vehicle EV of the user U from the second meter. In addition, when charging information is acquired, charging gateway device 20 notifies information processing device 100 of the acquired charging information. For example, the charging gateway device 20 transmits charging information in each time zone divided by predetermined time intervals (for example, every 30 minutes) to the information processing device 100 at predetermined time intervals.

The discharge gateway device 30 acquires from the third meter discharge information regarding the amount of discharge discharged from the electric vehicle EV of the user U to the charging/discharging facility installed in the manager's store. Further, when the discharge information is acquired, the discharge gateway device 30 notifies the information processing device 100 of the acquired discharge information. For example, the discharge gateway device 30 transmits discharge information to the information processing device 100 each time the user U completes one discharge.

The blockchain database 40 stores information about blockchains. For example, the blockchain database 40 stores information about a blockchain that records a history of transactions of power derived from renewable energy and a history of transactions of environmental value that is transferred together with the power derived from renewable energy.

The information processing device 100 provides power generation information about the amount of power generated by the generator PV, charging information about the amount of charge charged in the electric vehicle EV, and information about the amount of power discharged from the electric vehicle EV to the charging/discharging facility installed at the manager's store. It is an information processing device that collects discharge information related to the amount of discharge and records it in a blockchain. In addition, based on the collected information, the information processing apparatus 100 determines the amount of charge derived from renewable energy (the amount of charge derived from solar power generation in the example shown in FIG. 1) and the amount of discharge derived from renewable energy (in the example shown in FIG. , discharge amount derived from solar power generation) is calculated and recorded in the blockchain. The information processing apparatus 100 also displays the information registered in the blockchain on the screen so that the information can be browsed.

The communication unit 110 is realized by, for example, a NIC (Network Interface Card) or the like. The communication unit 110 is wired or wirelessly connected to the network N, and transmits and receives information to, for example, the power generation gateway device 10, the charging gateway device 20, the discharging gateway device 30, and the blockchain database 40.

The storage unit 120 is realized by, for example, a semiconductor memory device such as a RAM or flash memory, or a storage device such as a hard disk or an optical disk. For example, the storage unit 120 stores various programs (corresponding to an example of an information processing program).

Various operations are input to the input unit 130 by the user. For example, the input unit 130 may receive various operations from the user via a display surface (for example, the output unit 140) using a touch panel function. Further, the input unit 130 may receive various operations from buttons provided on the information processing device 100 or from a keyboard or mouse connected to the information processing device 100 .

The output unit 140 is, for example, a display screen realized by a liquid crystal display, an organic EL (Electro-Luminescence) display, or the like, and is a display device for displaying various information. The output unit 140 displays various information under the control of the control unit 150 . Note that when a touch panel is adopted for the information processing apparatus 100, the input unit 130 and the output unit 140 are integrated. Also, in the following description, the output unit 140 may be referred to as a screen.

The control unit 150 is a controller, and for example, various programs (information processing programs) stored in a storage device inside the information processing apparatus 100 are controlled by a CPU (Central Processing Unit), an MPU (Micro Processing Unit), or the like. (equivalent to one example) is implemented by executing the RAM as a work area. Also, the control unit 150 is a controller, and is implemented by an integrated circuit such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array).

As shown in FIG. 4, the control unit 150 includes an acquisition unit 151, a first calculation unit 152, a second calculation unit 153, a registration unit 154, and an output control unit 155, and performs information processing described below. achieve or perform the action of Note that the internal configuration of the control unit 150 is not limited to the configuration shown in FIG. 4, and may be another configuration as long as it performs information processing described later.

FIG. 5 is a diagram illustrating an overview of information processing by the information processing apparatus according to the embodiment; In FIG. 5, the acquisition unit 151 obtains power generation information about the amount of power generated by the generator PV, charge information about the amount of charge charged in the electric vehicle EV, Collect discharge information about the amount of discharge discharged.

In addition, in FIG. 5, the first calculator 152 determines, based on the amount of power generated by the generator PV and the amount of charge charged in the electric vehicle EV, that the amount of charge charged in the electric vehicle EV is calculates the amount of charge derived from photovoltaic power generation, which is the amount of charge derived from the power generated by . In addition, the registration unit 154 registers the calculated amount of charge derived from photovoltaic power generation in the blockchain.

In addition, in FIG. 5, the second calculation unit 153 is based on the amount of charge derived from solar power generation calculated by the first calculation unit 152 and the amount of discharge discharged from the electric vehicle EV to the charging/discharging equipment installed in the manager's store. Then, the amount of discharge derived from photovoltaic power generation, which is the amount of discharge derived from the power generated by the generator PV, is calculated out of the amount of discharge discharged to the charging/discharging equipment. In addition, the registration unit 154 registers the calculated discharge amount derived from photovoltaic power generation in the blockchain.

Further, in FIG. 5, the output control unit 155 displays the information registered in the blockchain by the registration unit 154 on the screen of the information processing apparatus 100 of each user so that the information can be browsed.

FIG. 6 is a diagram for explaining an example of a method for managing various meter IDs and the like according to the embodiment. In FIG. 6 , the acquisition unit 151 acquires the first meter ID that identifies the first meter and the power generation information regarding the amount of power generated by the power generator PV from the power generation gateway device 10 . For example, the acquiring unit 151 acquires the power generation information in each time period divided by predetermined time intervals (for example, every 30 minutes) at predetermined time intervals. Subsequently, when acquiring the first meter ID and the power generation information, the acquisition unit 151 associates the acquired first meter ID and the power generation information and registers them at the first address on the blockchain.

In addition, in FIG. 6 , the acquisition unit 151 acquires the second meter ID that identifies the second meter and the charge information regarding the charge amount of the electric vehicle EV of the user U from the charge gateway device 20 . For example, the acquisition unit 151 acquires the charging information in each time period divided by predetermined time (for example, every 30 minutes) at predetermined time intervals. Subsequently, when acquiring the second meter ID and the charging information, the acquiring unit 151 associates the acquired second meter ID with the charging information and registers them at the first address on the blockchain.

Here, as shown in the center of FIG. 6, the first address on the blockchain is associated with meter pair information, which is a pair of the first meter ID and the second meter ID. Also, the second address on the blockchain is associated with the user ID that identifies the user U and the third meter ID that identifies the third meter. Further, the meter pair information associated with the first address is associated with the user ID associated with the second address.

In this way, since the first meter ID and the second meter ID are linked to the user ID, it is possible to identify the user who owns the first meter or the second meter. Also, since the third meter ID is associated with the user ID, it is possible to identify the user who discharged the battery. A plurality of user IDs can be associated with one meter pair information.

Also, in FIG. 6, the acquiring unit 151 acquires the third meter ID that identifies the third meter and the discharge information regarding the amount of discharge from the user U's electric vehicle EV to the charging/discharging facility installed in the manager's store. Acquired from the discharge gateway device 30 . For example, the acquisition unit 151 acquires discharge information each time the user U completes one discharge. Subsequently, when acquiring the third meter ID and the discharge information, the acquiring unit 151 associates the acquired third meter ID and the discharge information and registers them at the second address on the block chain.

FIG. 7 is a diagram for explaining an example of a method for calculating a renewable energy-derived charge amount and an example of a measurement loss processing method according to the embodiment. In FIG. 7 , first, acquisition unit 151 determines whether or not a notification of the amount of power has been received from power generation gateway device 10 and charging gateway device 20 . When determining that the power amount notification has been received from the power generation gateway device 10 and the charging gateway device 20, the acquisition unit 151 determines whether or not the integrated value of the power generation amount and the integrated value of the charging amount at the time of the current notification have been acquired. .

When determining that the acquisition unit 151 has not acquired the integrated value of the power generation amount or the integrated value of the charged amount at the time of the current notification, the first calculation unit 152 ends the process. In the example shown in FIG. 7, the first calculation unit 152 obtains the integrated value of the power generation amount at the time of the current notification by the obtaining unit 151 at each time of 11:00, 13:00, 14:00, and 14:30. If it is determined that there is no, the process is terminated. Further, when the first calculation unit 152 determines that the acquisition unit 151 has not acquired the integrated value of the charging amount at the time of the current notification at each time of 12:00 and 13:00, the process ends.

On the other hand, if the first calculation unit 152 determines that the acquisition unit 151 has acquired the integrated value of the power generation amount at the time of the current notification and the integrated value of the charge amount at the time of the current notification, the first calculation unit 152 determines that the power generation amount at the time of the current notification acquired by the acquisition unit 151 (or The amount of power generation (or amount of charge) during the time slot is calculated by subtracting the integrated value of the amount of power generation (or amount of charge) at the time of the previous notification from the integrated value of the amount of charge. In the example shown in FIG. 7 , the first calculation unit 152 obtains the integrated power generation amount “20.0” and the charge amount integrated value “20. 180.0” is acquired. Subsequently, the first calculation unit 152 converts the integrated value of the power generation amount at the time of the current notification acquired by the acquisition unit 151 from “20. 0” is subtracted to calculate the power generation amount “10.0” in the time period from 9:30 to 10:00. Further, the first calculation unit 152 calculates the integrated value of the charge amount at the time of 9:30, which is the time of the previous notification, from the integrated value of the charge amount at the time of the current notification acquired by the acquisition unit 151, which is “150.0. 0” is subtracted to calculate the charge amount “30.0” in the time period from 9:30 to 10:00.

Here, in a certain time period, when the amount of charge in the electric vehicle EV is larger than the amount of power generated by the generator PV, the amount of charge in the electric vehicle EV is equal to the amount of power generated by the generator PV. It is considered that the battery is charged with two types of electric energy, ie, the electric energy generated and the electric energy generated by the power generating equipment other than the generator PV. Therefore, of the charge amount charged in the electric vehicle EV in a certain time period, the renewable energy-derived charge amount derived from the renewable energy generated by the generator PV matches the amount of power generated by the generator PV. should be.

Further, in another time zone, if the amount of charge charged in the electric vehicle EV is smaller than the amount of power generated by the generator PV, the amount of power generated by the generator PV is used to charge the electric vehicle EV. It is thought that the battery was used for two types of charging: the charging amount that was used for charging and the charging amount that was used for equipment other than the electric vehicle EV. Therefore, of the charging amount of the electric vehicle EV in a different time period, the renewable energy-derived charging amount derived from the renewable energy generated by the generator PV is the same as the charging amount of the electric vehicle EV. should match.

Therefore, the first calculation unit 152 compares the calculated differential power generation amount in the time slot with the differential charge amount in the time slot, and determines whether the difference in the power generation amount in the time slot or the differential charge amount in the time slot is smaller. The other value is calculated as the renewable energy-derived charge amount in the time slot. In the example shown in FIG. 7, the first calculator 152 compares the power generation amount “10.0” and the charge amount “30.0” in the time period from 9:30 to 10:00, and determines the smaller one. The value of the power generation amount “10.0” is calculated as the renewable energy-derived charge amount “10.0” in the time period from 9:30 to 10:00.

Further, when the acquisition unit 151 does not acquire the amount of power generation in the predetermined time period, the first calculation unit 152 calculates the difference in the amount of power generation in the time periods before and after the predetermined time period. It is calculated as the power generation amount in a time period including time periods before and after the predetermined time period. In the example shown in FIG. 7, the power generation amount in the time period from 10:30 to 11:00 is not acquired by the acquisition unit 151, so the first calculation unit 152 calculates the time period from 10:30 to 11:00. The amount of power generation in the time period from 11:00 to 11:30 after "40.0" and the power generation in the time period from 10:00 to 10:30 before the time period from 10:30 to 11:00 The difference "10.0" from the amount "30.0" is calculated as the power generation amount in the time period from 10:00 to 11:30.

Further, when the acquisition unit 151 does not acquire the accumulated charge amount value in the predetermined time period, the first calculation unit 152 calculates the difference in the charge amount in the time periods before and after the predetermined time period. It is calculated as the amount of charge in a time slot including the time slot and the time slots before and after the predetermined time slot. In the example illustrated in FIG. 7 , since the acquisition unit 151 did not acquire the charge amount in the time period from 11:30 to 12:00, the first calculation unit 152 The accumulated charge amount "210.0" in the time period from 12:00 to 12:30 after and the time period from 11:30 to 12:30 before the time period from 11:30 to 12:00 "15.0", which is the difference from the charge amount integrated value "195.0" at 11:30 to 12:30, is calculated as the charge amount in the time period from 11:30 to 12:30.

The registration unit 154 associates the renewable energy-derived charge amount calculated by the first calculation unit 152 with the meter pair information and registers them at the first address on the blockchain. Further, when the first calculation unit 152 calculates the renewable energy-derived charge amount, the registration unit 154 issues an environmental value token indicating an environmental value corresponding to the renewable energy-derived charge amount.
