The boosted voltage is used to drive the first motor generator 41 and the second motor generator 42, and both high output and low power loss can be achieved. Step-down converter 32 steps down the voltage of power storage device 30 to a predetermined voltage (for example, DC288V to 12V) and applies it to load 33 such as an auxiliary battery, navigation device, or the like.

  The first inverter 43 and the second inverter 44 convert the high-voltage direct current boosted by the boost converter 31 into alternating current for supplying the first motor generator 41 and the second motor generator 42, respectively. Each inverter 43, 44 also functions to convert an alternating current generated by each motor generator 41, 42 into a direct current.

  The vehicle control ECU 10 is configured to be able to communicate with the engine ECU 2, the motor generator ECU 4, the power storage device ECU 3, the charger ECU 5, and the like. The vehicle control ECU 10 stores a unique management number (vehicle ID) that identifies the vehicle 1, and notifies the vehicle ID to the power feeder 50 via the communication device 9 when performing the power feeding operation.

  The vehicle control ECU 10 calculates an engine output and a motor torque according to the driving state based on signals from various sensors, and outputs a required value to each ECU to control the driving force of the driving wheels 23. The engine ECU 2 controls the power of the engine 20 by controlling the electronic throttle according to the engine output request from the vehicle control ECU 10. The motor generator ECU 4 controls the first motor generator 41, the second motor generator 42, the first inverter 43, the second inverter 44, and the boost converter 31 based on a signal from the vehicle control ECU 10.

  The control circuit 6 is configured to include a rectifier circuit and a step-up / step-down circuit, and converts high-frequency AC power obtained from an external system power supply or the like via the ground side power supply unit 51 and supplies it to the power storage device 30. The charger ECU 5 is a means for determining whether or not there is a power supply request to the vehicle-side power receiving unit 7, and is an electronic control device that controls charging / discharging of the power storage device 30.

  The power supply request includes a request for charging the power storage device 30 based on an operation of the user or the like while the vehicle is stopped, and a request for driving auxiliary equipment. It is satisfied when the charger ECU 5 determines that the power receiving unit 7 is located in a range where power can be supplied.

  The charger ECU 5 is configured to be communicable with various loads 33, 34 and the like via the vehicle control ECU 10, and is provided with a communication circuit 9 provided on the control circuit 52 on the ground side power feeding section 51 through the communication device 9 on the vehicle 1 side.

Processing is also performed.

  The switchboard 102 in the building 100 performs a function of allocating electric power such as an external system power supply to the loads 103, 104, 105, etc. of equipment used on the building side. This allocation function is performed by the building control device controlling the switchboard 102. The power feeder 50 can communicate various information with the communication device 9 in the vehicle 1 via the communication device 54.

  The vehicle 1 includes a power split mechanism 21 including a planetary gear mechanism. The power split mechanism 21 splits the power of the first motor generator 41, the second motor generator 42, and the engine 20.

  The first motor generator 41, the engine 20, and the second motor generator 42 are mechanically coupled to the sun gear, carrier, and ring gear of the power split mechanism 21, respectively. Drive wheels 23 are mechanically connected to the second motor generator 42 via the axles 22. The axle 22 is a shaft for transmitting the power output from the engine 20 and the second motor generator 42 to the drive wheels 23. A first inverter 43 and a second inverter 44 are connected to each of the first motor generator 41 and the second motor generator 42.

  The operation state of each part of the vehicle 1 in the above configuration will be described. The vehicle 1 travels only by the second motor generator 42 that operates by supplying power from the power storage device 30 until the power storage device 30 becomes a predetermined SOC (state of charge) or less. When the engine 1 is not efficient, such as when starting, when traveling at a very low speed, or traveling on a gentle downhill, the second motor that operates by supplying power from the power storage device 30 while the engine 20 is stopped. The vehicle travels only with the generator 42. During normal travel, the power of the engine 20 is divided into two paths, one driving the drive wheels 23 via the axle 22, and the other driving the first motor generator 41 to generate electric power. Driving the second motor generator 42 with the generated power assists the driving force of the engine 20. The vehicle control ECU 10 controls the engine 20, the first motor generator 41, and the second motor generator 42 so as to obtain the maximum efficiency. Further, at the time of acceleration, electric power is supplied from the power storage device 30 and a driving force by the second motor generator 42 is further added.

  At the time of deceleration and braking, the driving wheel 23 operates the second motor generator 42 as a generator to perform regenerative power generation. The regenerated power is stored in the power storage device 30. When the vehicle is stopped, the engine 20 and the motor generators 41 and 42 are stopped except during cooling, during engine warm-up, and during charging. During traveling when the power storage device 30 needs to be charged, the output of the engine 20 is increased, and surplus power generated by the first motor generator 41 is charged to the power storage device 30.

  Next, the operation | movement which concerns on the electric power feeding operation which an electric power feeding management apparatus implements is demonstrated with reference to FIG.3 and FIG.4. FIG. 3 is a flowchart showing a processing procedure of the power feeding operation in the vehicle 1. FIG. 4 is a flowchart showing a processing procedure of the power feeding operation in the power feeder 50. As shown in FIGS. 3 and 4, the vehicle 1 and the power feeder 50 communicate information with each other, and one performs the subsequent processing using information received from the other. For example, information communication is performed by transmitting and receiving data between the communication device 9 and the communication device 54.

  In the vehicle 1, the vehicle control ECU 10 determines in step 1 whether or not the vehicle 1 is in a parking completed state in which power can be supplied to charge the power storage device 30. That is, in the case of non-contact power feeding, it is determined whether or not the vehicle-side power receiving unit 7 is located in a range where power can be received from the ground-side power feeding unit 51. Then, the vehicle 1 is stopped, and it is determined whether or not the power feeding port on the power feeder 50 side and the power receiving port of the vehicle 1 are connected with a cable by plug connection or the like. If it is determined in step 1 that the parking is complete, it is determined in step 2 whether or not there is a power supply request for charging. This power supply request is satisfied, for example, when there is a charge request to the power storage device 30 or a drive request for auxiliary equipment based on an operation of a user or the like. If it is determined that there is a power supply request, the information “power supply request exists” is transmitted to the power feeder 50.

  In the power feeder 50, the power feeder ECU 53 determines in step 50 whether the start-up process for supplying power to the vehicle 1 has been completed. If it is determined in step 51 that the activation process is complete, then in step 51, it is confirmed based on the “power supply requested” information received from the vehicle 1 after step 2 that a power receiving vehicle exists. The process is executed, and information on “execution of vehicle confirmation process” is transmitted to the vehicle 1.

  In the vehicle 1, in step 3, a process of confirming the power supply destination power supply 50 is executed based on the “vehicle confirmation process execution” information received from the power supply 50 after step 51. Next, in step 4, the vehicle 1 The unique management number, that is, the vehicle ID information is transmitted to the power feeder 50.

  In step 52, power feeder 50 determines whether or not the information of “vehicle ID” has been received from vehicle 1 after step 4. If it is determined in step 52 that the “vehicle ID” information has been received, then in step 53, it is determined whether the vehicle 1 can be authenticated as a power supply target vehicle as a result of collating the vehicle ID. Information on “authentication permission / denial result” is transmitted. If it is determined that the authentication is not permitted, the process returns to step 52 to determine again whether or not the “vehicle ID” information is received.

  At this time, if it is determined that the received vehicle ID is an unauthorized vehicle ID, it is determined that authentication cannot be performed. The unauthorized vehicle ID is, for example, a vehicle that has been illegally modified, a vehicle registered as a stolen vehicle, or the like.

  In the vehicle 1, in step 5, it is determined whether or not the power feeder 50 has permitted the authentication of the vehicle 1 based on the “authentication permission rejection result” information received from the power feeder 50 (step 53). If the authentication is not permitted, the process returns to step 4 to transmit the “vehicle ID” information to the power feeder 50 again. In the case of authentication permission, the process proceeds to step 6, where preparation for receiving power necessary for receiving power in the vehicle 1 is completed and information on “ready for receiving power” is transmitted to the power feeder 50.

  The power feeder 50 receives the information “ready for power reception” from the vehicle 1, completes the power feed preparation necessary for the power feeding operation in the power feeder 50 in step 54, and sends the information “ready for power feed ready” to the vehicle 1. Send to.

  In the vehicle 1, the information “preparation for power feeding” is received from the power feeder 50 in step 7. Next, in step 8, information of “vehicle ID” and “power supply request” is transmitted to the power feeder 50.

  In the power feeder 50, if it is determined in step 55 that the information of “vehicle ID and power supply request command” is received from the vehicle 1 and it is determined in step 55 that the information of “vehicle ID and power supply request command” is received, the next step is performed. In 56, it is determined whether or not the received vehicle ID can be authenticated as an appropriate power supply target vehicle as a result of collating the received vehicle ID with the vehicle ID that has already been authenticated. Furthermore, information of “authentication permission / denial result” is transmitted to the vehicle 1. If it is determined that the authentication is not permitted, the process returns to step 55 to determine again whether or not the “vehicle ID and power supply request command” information is received.

  In the power feeder 50, when it is determined that the authentication can be performed in Step 56, the process proceeds to Step 57, and the power that can be supplied to the vehicle 1 that has been authenticated is calculated. Furthermore, the information of the calculated “power that can be supplied” is transmitted to the vehicle 1 for which permission is determined. The power that can be supplied is calculated based on, for example, a total power amount that is the power supply capability of the power supply 50 and a power supply schedule that includes the amount of power supplied by other vehicles, the power supply time, the power supply time, and the like. The calculated value is the amount of electric power that can be allocated to the vehicle 1 in consideration of the balance with other vehicles.

  In the vehicle 1, based on the “authentication permission rejection result” information (step 56) received from the power feeder 50, it is determined in step 9 whether or not the power feeder 50 permits the vehicle 1 to be authenticated. If the power feeder 50 determines that authentication is not permitted, the process ends without performing the power reception start process. If the authentication is permitted, the process proceeds to step 10 to prepare for the start of power reception.

  In the vehicle 1, information on “power that can be supplied” calculated in step 57 is received from the power supply 50, and in response to this, in step 10, a necessary amount of power that the vehicle 1 requests to receive power is calculated, and the power supply 50 Information of “required received power amount” is transmitted to The required amount of received power is obtained by inputting the SOC that the user wants to secure in the power storage device 30 or by calculating the amount of power required for driving the auxiliary equipment or traveling the vehicle.

  In the power feeder 50, the “necessary received power amount” information calculated in step 10 is received from the vehicle 1, and in response to this, power supply to the vehicle 1 is started in step 58. Then, this information is transmitted to the vehicle 1.

  In vehicle 1, power reception for charging power storage device 30 is started in step 11. Then, after the start of power reception, the “power supply start information” from the power feeder 50 is received, and the total amount of power received from the start of power reception is measured in step 12. Further, in step 13, “vehicle ID” and “total value information of received power amount after the start of power reception in the vehicle 1” are transmitted to the power feeder 50.

  The power feeder 50 receives the “vehicle ID” and the “total amount of received power amount information” from the vehicle 1, and in step 59, “determines whether the vehicle 1 can be authenticated as a power supply target vehicle” and “ “Determining whether or not the total value information of the received power matches the amount of power supplied to the vehicle 1 from the power feeder 50”. In this matching, in order to take into account measurement error, the amount of power lost in the power feeding or power receiving process, etc., when the difference between the power receiving power amount and the power feeding power amount is within a preset predetermined power amount, Both electric power amounts are determined to match. In step 59, consistency is determined by comparing a value obtained by adding the predetermined power amount α to the received power amount and the supplied power amount.

  If it is determined in step 59 that the two items match, the power supply operation is continued until it is determined in step 60 that the power supply end condition is satisfied. The case where the power supply end condition is satisfied is, for example, that the condition of the charge end SOC is satisfied.

  If it is determined in step 60 that the power supply end condition is not satisfied, the process returns to step 55, and the subsequent “authentication permission determination” and “consistency determination between received power amount and supplied power amount” are executed again, and an appropriate power supply operation is performed. Check if is done. If it is determined in step 60 that the power supply end condition is satisfied, a process for stopping the power supply operation is executed in step 61, and this flow is ended.

  If the power feeder 50 determines that the two items do not match in step 59, the power feeder 50 determines that the power supplied from the power feeder 50 is not properly received by the authenticated vehicle 1, and some problem occurs. It is considered to be. And the process which stops electric power feeding operation by step 63 is performed. Further, in step 64, the manager 56 managing the power feeder 50 and the external organization 60 are notified of such a problem via the communication device 54 and also notified to the vehicle 1. Thus, the notification unit 8 of the vehicle 1 informs the user of the current problem. After the notification in step 64, this flow is ended, and the user, the administrator of the power feeder 50, the security company, the external organization such as the police, etc. can take measures to solve the problem.

  The notification unit 8 of the vehicle 1 notifies the occupant of the vehicle 1 and the vicinity of the vehicle 1 of the occurrence of the problem by sound means, illumination means, or display means. In the case of sound, a horn or electronic sound at the time of opening / closing the door, in the case of lighting, lighting of headlights, room lamps, tail lamps, etc., and blinking of hazards, in the case of display, the instrument display located in front of the handle or in the center of the dashboard Display on a liquid crystal display placed on a part of the board.

  The vehicle 1 continues to receive power until it is determined in step 14 that the power supply end condition is satisfied. If it is determined in step 14 that the power supply termination condition is not satisfied, the process returns to step 8 and the subsequent “authentication permission determination by power feeder 50” and “measurement of received power amount” are executed again. If it is determined in step 14 that the power supply termination condition is satisfied, a process for stopping the power receiving operation is executed in step 15 and this flow is terminated.

  In the above flow, a timeout is set for communication between the vehicle 1 and the power feeder 50. Then, when the communication of information is not completed within a predetermined time, the power feeding operation may be interrupted.

  The effect which the electric power feeding management apparatus of this embodiment brings is demonstrated. The power supply management device manages a power supply operation for supplying power from the power feeder 50 to the vehicle 1 that stores power for traveling. The power supply management device authenticates the unique management information of the vehicle 1 during the power supply operation (step 56), and the amount of power supplied by the power supply 50 and the amount of power received by the vehicle 1 match. If it is confirmed, it is determined that power is continuously supplied to the same vehicle 1 from the start of the power supply operation, and the power supply operation is continued (step 59, step 60).

  According to this, during power supply operation, while authenticating that power is being supplied to the vehicle 1 that is a regular power supply target, power supply from the power feeder 50 is properly received by the vehicle 1 that is the power supply target. When it is confirmed that the power supply operation is correct, it is determined that the proper power supply operation is performed. By this determination, for example, it is possible to detect the act of charging by changing the power supply cable to another vehicle in the middle of the power supply operation, and other vehicles other than the properly authenticated vehicle 1 are charged. Can be prevented.

  Further, in the case of non-contact power feeding in which power is fed to the vehicle 1 in a non-contact manner using a method such as electromagnetic coupling or resonance without using a power feeding cable, a plurality of power receiving units are provided near the ground-side power feeding unit 51 of the power feeder 50.

According to this, during power feeding operation, it has been recognized that power feeding is being performed on a vehicle 1A different from the vehicle 1 that is a regular power feeding target, and the power feeding from the power feeder 50 depends on the vehicle to be fed. If any of the cases in which it is not possible to confirm that all the power is received, the power feeding operation is stopped and the inappropriate power feeding operation is terminated. For this reason, when an unauthorized power receiving action or a power feeding operation to a power feeding destination contrary to the intention of the user is performed, such a situation can be immediately resolved and the problem can be solved early.

  If any of the authentication approval / disapproval determination in step 56 and the consistency determination in step 59 is not established, the power supply management device is assigned to at least one of the user of the vehicle 1, the external engine 60, and the administrator of the power supply 50. Notification is made (step 64).

  According to this, during power feeding operation, it has been recognized that power feeding is being performed on a vehicle different from the vehicle 1 that is a regular power feeding target, and the power feeding from the power feeder 50 is performed by the vehicle 1 that is the power feeding target. If any of the cases where it is not possible to confirm that all the power is received, the occurrence of the problem is notified to at least one of the user, the external organization 60, and the manager of the power feeder 50. As a result, the user of the vehicle 1, the administrator of the power feeder 50, the security company, the external organization 60 such as the police can know the occurrence of the problem at an early stage. It becomes possible to take improvement measures at an early stage. Therefore, it is possible to improve the trouble situation reliably and promptly and improve the deterrent effect of acts such as unauthorized power reception.

FIG. 5 is a flowchart showing a processing procedure of the power feeding operation in the power feeder 50. The flow described in the second embodiment is a modification of the flow described in the first embodiment, and only the parts different from the first embodiment will be described below. Therefore, in the description of the present embodiment, FIGS. 3 and 4 are referred to as necessary.

  As shown in FIG. 5, in the power feeder 50, when it is determined that the authentication can be performed in step 56 of FIG. 4, it is determined in step 100 whether or not a plurality of authenticated vehicle IDs are received. Here, it is determined whether or not IDs corresponding to a plurality of vehicles whose power feeding should be managed have been received. If it is determined in step 100 that the IDs of the plurality of vehicles have not been received, the process proceeds to step 55 in FIG. 4, and thereafter, the process according to the flowchart in FIG. Conversely, if it is determined that the IDs of the plurality of vehicles have been received, in step 101, the received power amount is received from each of the plurality of vehicles.

  In step 102, it is determined whether or not the received power amount has been received from all of the plurality of vehicles. If it is determined in step 102 that all have not been received, the process returns to step 101. If it is determined that all have been received, the process proceeds to step 103. In step 103, the amount of power that can be supplied to the vehicle that has been authenticated is calculated.

  In step 104, it is determined whether or not “the amount of power that can be supplied” calculated in step 103 is equal to or greater than the “total amount of received power of all vehicles” confirmed in step 102. If the determination in step 104 is NO, in step 105, each vehicle is requested to change the amount of received power. The request for changing the received power amount at this time is to change the received power amount of each vehicle to a value such that the sum of all the received power amounts does not exceed the power supplyable power amount.

  In response to the change request in step 105, if there is an answer to the amount of received power from each vehicle, in step 106, the “power supplyable energy” in step 103 is changed to “the sum of the received power amounts of all vehicles”. It is determined whether or not. If the determination in step 106 is NO, the process proceeds to step 63 in FIG. 4, and thereafter, the process according to the flowchart in FIG. If the determination in step 106 is YES, the process proceeds to step 107 described later. According to these processes, even if there is a request exceeding the supply capacity of the power feeder 50 from a plurality of vehicles, it is possible to carry out appropriate power supply according to the supply capacity and to smoothly perform the power supply operation. it can.

  If the determination in step 104 is YES, power supply to the vehicle 1 is started in step 107. Then, this information is transmitted to the vehicle 1.

  The power feeder 50 receives the “vehicle ID” and “received power amount information” from each of the plurality of vehicles, and in step 108, “determines whether each vehicle can be authenticated as a power supply target vehicle” and “all "Determining whether or not the total value of the received power amount of the vehicle matches the amount of power supplied to the plurality of vehicles from the power feeder". In this matching, the difference between the total amount of received power and the amount of supplied power is within a predetermined amount of power set in advance in order to take into account measurement error and the amount of power lost in the process of feeding or receiving power. Therefore, it is determined that both electric power amounts match. In step 108, consistency is determined by comparing a value obtained by adding the predetermined power amount α to the total value of the received power amount and the power supply power amount.

  If it is determined in step 108 that the two items match, the power supply operation is continued until it is determined in step 109 that the power supply end condition is satisfied for all vehicles. The case where the power supply end condition is satisfied is, for example, that the condition of the charge end SOC is satisfied.

  If it is determined in step 109 that the power supply termination condition is not satisfied, the process returns to step 100 and the subsequent processes are executed again to check whether an appropriate power supply operation is performed. If it is determined in step 109 that the power supply end condition is satisfied, the process proceeds to step 61 in FIG. 4, a process for stopping the power supply operation is executed, and this flow is ended.

  If the power feeder 50 determines in step 108 that all the two items are not matched, the power feeder 50 determines that the power supplied from the power feeder 50 is not properly received by a plurality of authorized vehicles, and there is some problem. It is considered to have occurred. Then, the process proceeds to step 63 in FIG. 4, a process for stopping the power feeding operation is executed, and a process according to the flowchart in FIG. 4 is performed.

  According to the power supply management device of the present embodiment, even when a plurality of vehicles are used as power supply target vehicles, a power supply management device that can prevent unauthorized power supply and perform appropriate power supply can be obtained.
