[0008] An embodiment of the control device will be described below with reference to the drawings. <Overview of the charging and discharging system> As shown in Figure 1, the charging and discharging system 10 comprises a vehicle 20, a charging device 60, a portable terminal device 70, and a server 80. The charging and discharging system 10 is a system that controls the battery 23 mounted on the vehicle 20, which is an electric vehicle.

[0009] The vehicle 20 includes a connection port 21, a charge / discharge unit 22, and a battery 23. The connection port 21 can be connected to a connector that is connected to the power supply cable of the charging device 60. When the connector is connected to the connection port 21, the battery 23 is in a state where it can be charged and discharged.

[0010] Battery 23 stores power to drive a motor (not shown) which is the power source for the vehicle 20. The charge / discharge unit 22 is located between the connection port 21 and the power line connecting the battery 23. The charge / discharge unit 22 includes a relay that switches between connecting and disconnecting the power path from the connection port 21 to the battery 23, and a power conversion circuit. The charge / discharge unit 22 is configured to enable charging of the battery 23 from the charging device 60 and discharging of the battery 23 to the charging device 60.

[0011] The vehicle 20 includes a control device 30, an input device 40, and a communication device 50. The control device 30 controls the battery 23 by transmitting a control signal MS to the charge / discharge unit 22. The control device 30 includes a CPU 31 and a memory 32. The memory 32 stores an arbitration map MP containing an arbitration rule RL and an arbitration program PR. By the CPU 31 referring to the arbitration rule RL and executing the arbitration program PR, the control device 30 functions as an acquisition unit 30A, an arbitration unit 30B, an output unit 30C, and a mode identification unit 30D as shown in Figure 4. Details of the control device 30 will be described later.

[0012] As shown in Figure 1, the input device 40 inputs information entered by the user of the vehicle 20 to the control device 30. The input device 40 is, for example, a touch display. The input device 40 inputs information indicating the vehicle mode MD, which is the charging and discharging mode of the vehicle 20, to the control device 30. The input device 40 also inputs charge / discharge requests DS related to the charging and discharging of the vehicle 20 to the control device 30.

[0013] The communication device 50 communicates with the charging device 60, the mobile terminal device 70, and the server 80 via a wireless communication network. The communication device 50 inputs the information obtained from these devices to the control device 30.

[0014] The charging device 60 comprises a power supply circuit 61, a control module 62, an operation module 63, and a communication module 64. The charging device 60 is a so-called EVSE (Electric Vehicle Supply Equipment). The power supply circuit 61 is connected to the end of the power supply cable opposite the connector. The power supply circuit 61 is connected to an external power source 91. The power supply circuit 61 can input electricity from the power source 91 to the vehicle 20 via the power supply cable. The power supply circuit 61 is also connected to an external house 92. The power supply circuit 61 can input electricity from the vehicle 20 to the house 92.

[0015] The operation module 63 receives user input for the charging device 60. The operation module 63 is, for example, a touch display. The communication module 64 communicates with the vehicle 20's communication device 50 via a wireless communication network. Based on the operation signals received by the operation module 63, the control module 62 transmits a charge / discharge request DS related to the charging and discharging of the vehicle 20 from the communication module 64 to the vehicle 20.

[0016] The mobile terminal device 70 comprises a control module 71, an operation module 72, and a communication module 73. The operation module 72 receives operations from the user of the mobile terminal device 70. The operation module 72 is, for example, a touch display. The communication module 73 communicates with the communication device 50 of the vehicle 20 via a wireless communication network. Based on the operation signals received by the operation module 72, the control module 71 transmits a charge / discharge request DS regarding the charging and discharging of the vehicle 20 from the communication module 73 to the vehicle 20.

[0017] The server 80 includes a control module 81 and a communication module 82. The communication module 82 communicates with the communication device 50 of the vehicle 20 via a wireless communication network. The control module 81 performs charge and discharge control of the vehicle 20. In the present embodiment, the control module 81 performs charge and discharge control by utilizing the vehicle 20, which is an electric vehicle, as a resource of a so-called VPP (Virtual Power Plant). By performing charge and discharge control, the control module 81 transmits a charge and discharge request DS regarding the charge and discharge of the vehicle 20 from the communication module 82 to the vehicle 20. In the present embodiment, the plurality of devices that are the transmission sources of the charge and discharge request DS are the input device 40, the charging device 60, the portable terminal device 70, and the server 80.

[0018] <Specific example of charge and discharge request> Next, specific examples of the charge and discharge request DS acquired by the control device 30 from each device will be described. The charge and discharge request DS1 as the first specific example and the charge and discharge request DS2 as the second specific example will be described.

[0019] In the first specific example shown in FIG. 2, the charge and discharge request DS is a reservation request to start charge control at a predetermined time t1. The charge and discharge request DS1 includes a charge request CH and is a reservation request.

[0020] Specifically, in the first specific example, the unit price P of the electricity charge from time t1 to time t2 after time t1 is the unit price P1. The unit price P of the electricity charge from time t2 to time t3 after time t2 is a unit price P2 higher than the unit price P1. The unit price P of the electricity charge from time t3 to time t4 after time t3 is the unit price P1. The unit price P of the electricity charge from time t4 to time t5 after time t4 is the unit price P2. The unit price P of the electricity charge from time t5 to time t6 after time t5 is the unit price P2.

[0021] The charge / discharge request DS1 includes a charge request CH for the period from time t1 to time t2, a charge request CH for the period from time t3 to time t4, and a charge request CH for the period from time t5 to time t6. Furthermore, the charge / discharge request DS1 includes a non-request NC for no charging or discharging between time t2 and time t3, and a non-request NC for no charging or discharging between time t4 and time t5.

[0022] In this case, the charge / discharge request DS1 requests charging between time t1 and time t2, between time t3 and time t4, and between time t5 and time t6. On the other hand, the charge / discharge request DS1 does not request charging between time t2 and time t3, and between time t4 and time t5.

[0023] If the battery 23 is charged according to the charge / discharge request DS1, the charge level C of the battery 23 will increase from the charge level C1 at time t1 to the charge level C2 at time t6. Therefore, the charge / discharge request DS1 is a request that includes a period of time t1 to time t6 during which charging is requested and a period during which charging is not requested. Thus, the charge / discharge request DS1 initiates charging control at time t1. Therefore, the charge / discharge request DS1 is both a reservation request and a request for charging, which is performed according to the unit price P of the electricity charge.

[0024] In the second specific example shown in Figure 3, the charge / discharge request DS2 includes a charge request CH and a discharge request DCH. Furthermore, the charge / discharge request DS2 initiates discharge control at a predetermined time t11. In other words, the charge / discharge request DS2 is a reservation request.

[0025] The charge / discharge request DS2 includes a charge request CH for the period from time t11 to time t12 (after time t11), a discharge request DCH for the period from time t12 to time t13 (after time t12), and a charge request CH from time t13 onwards.

[0026] In this case, the charge / discharge request DS2 requests charging when time t11 arrives. The charge / discharge request DS2 requests discharging between time t11 and time t12. The charge / discharge request DS2 stops requesting discharging and requests charging when time t13 arrives.

[0027] Assuming that the battery 23 is charged according to the charge / discharge request DS2, the charge level C of the battery 23 gradually increases from time t11 until it is fully charged from time t11 to time t12. Then, at time t12, the battery 23 begins to discharge, and the charge level C of the battery 23 begins to decrease. Then, at time t13, the battery 23 begins to charge again, and the charge level C of the battery 23 begins to increase.

[0028] In the second specific example, because a large amount of electricity is used in the house 92 between time t12 and time t13, a discharge request DCH is reserved for the period between time t12 and time t13. Furthermore, the charge / discharge request DS2 includes a charge request CH between time t11 and time t12, and a charge request CH from time t13 onwards. Therefore, the charge / discharge request DS2 is a request to perform charge / discharge control, including discharge control, to meet the electricity usage in the house 92.

[0029] Thus, a charge / discharge request DS may include a charge request CH and a discharge request DCH within a predetermined period. Another example of a charge / discharge request DS is one in which charging is requested during multiple periods calculated to minimize carbon dioxide emissions within a predetermined period, and charging is not requested outside of those multiple periods. Another example of a charge / discharge request DS is one in which, when controlling the charging and discharging of multiple vehicles 20, the charging periods are set to be staggered for multiple vehicles 20 in order to sequentially charge from a single power source 91 to multiple vehicles 20.

[0030] <Functions of the control device using the mediation program> Next, we will describe each functional unit that operates when the CPU 31 executes the arbitration program PR.

[0031] As shown in Figure 4, the control device 30 includes an acquisition unit 30A, an arbitration unit 30B, an output unit 30C, and a mode identification unit 30D. In the following, when it is necessary to distinguish between multiple charge / discharge request DS, the charge / discharge request DS whose source device is the input device 40 will be designated as the first request D1. The charge / discharge request DS whose source device is the mobile terminal device 70 will be designated as the second request D2. The charge / discharge request DS whose source device is the charging device 60 will be designated as the third request D3. The charge / discharge request DS whose source device is the server 80 will be designated as the fourth request D4. Each charge / discharge request DS is assigned an ID that identifies the source device, for example.

[0032] The acquisition unit 30A acquires charge / discharge requests DS for the battery 23 from multiple devices. Specifically, the acquisition unit 30A acquires the first request D1 from the input device 40. The acquisition unit 30A acquires the third request D3 from the charging device 60 via the communication device 50. The acquisition unit 30A acquires the second request D2 from the mobile terminal device 70 via the communication device 50. The acquisition unit 30A acquires the fourth request D4 from the server 80 via the communication device 50. The acquisition unit 30A inputs the acquired charge / discharge requests DS to the arbitration unit 30B.

[0033] The mode identification unit 30D identifies the vehicle mode MD based on the information indicating the vehicle mode MD input from the input device 40. The mode identification unit 30D then inputs the information indicating the identified vehicle mode MD to the arbitration unit 30B.

[0034] The arbitration unit 30B arbitrates the multiple charge / discharge requests DS acquired by the acquisition unit 30A based on the device that transmitted the charge / discharge requests DS. The arbitration unit 30B arbitrates by referring to the arbitration rule RL. Details of the arbitration will be described later. The arbitration unit 30B then inputs the control request DC, which is the result of the arbitration, to the output unit 30C.

[0035] The output unit 30C outputs a control signal MS for controlling the battery 23 based on the control request DC. For example, based on the charge / discharge request DS arbitrated as the control request DC, the output unit 30C outputs time-series data of signals indicating charging ON, charging OFF, discharging ON, and discharging OFF to the battery 23 as a control signal MS to the charge / discharge unit 22.

[0036] <Mediation based on mediation rules> Next, we will describe the details of the arbitration performed by the arbitration unit 30B, based on the device that transmitted the charge / discharge request DS, with reference to the arbitration rule RL.

[0037] As shown in Figure 5, the arbitration map MP includes multiple vehicle modes MD and arbitration rules RL associated with each vehicle mode MD. Specifically, the first vehicle mode MD1 is associated with the first arbitration rule RL1. The first vehicle mode MD1 is a mode that prohibits external control. The first arbitration rule RL1 allows the selection of a charge / discharge request DS with input device 40 as the source device. On the other hand, the first arbitration rule RL1 prohibits the selection of a charge / discharge request DS with mobile terminal device 70, charging device 60, and server 80 as the source devices.

[0038] The second vehicle mode MD2 is associated with the second arbitration rule RL2. The second vehicle mode MD2 is a mode that permits the operation of the mobile terminal device 70. The second arbitration rule RL2 permits the selection of charge / discharge request DS with the input device 40 and the mobile terminal device 70 as the source devices. On the other hand, the second arbitration rule RL2 prohibits the selection of charge / discharge request DS with the charging device 60 and the server 80 as the source devices.

[0039] The third vehicle mode MD3 is associated with the third arbitration rule RL3. The third vehicle mode MD3 is a mode that only permits the operation of the charging device 60. On the other hand, the third arbitration rule RL3 prohibits the selection of charge / discharge request DS with the input device 40, the mobile terminal device 70, and the server 80 as the source devices.

[0040] The fourth vehicle mode MD4 is associated with the fourth arbitration rule RL4. The fourth vehicle mode MD4 is a mode that only allows operation of the server 80. On the other hand, the fourth arbitration rule RL4 prohibits the selection of charge / discharge request DS with the input device 40, charging device 60, and mobile terminal device 70 as the source devices.

[0041] As shown in Figure 6, each vehicle mode MD is further subdivided. Each vehicle mode MD includes a discharge-prohibition mode and a discharge-permitting mode. The arbitration rule RL associated with the discharge-prohibition mode permits charging while prohibiting discharging. The arbitration rule RL associated with the discharge-permitting mode permits both charging and discharging.

[0042] In other words, in this embodiment, the multiple vehicle modes MD include a discharge prohibition mode and a discharge permitting mode in the first vehicle mode MD1, and a discharge prohibition mode and a discharge permitting mode in the second vehicle mode MD2. Furthermore, the multiple vehicle modes MD also include a discharge prohibition mode and a discharge permitting mode in the third vehicle mode MD3, and a discharge prohibition mode and a discharge permitting mode in the fourth vehicle mode MD4.

[0043] As shown in Figure 4, the arbitration unit 30B refers to the arbitration rule RL associated with the vehicle mode MD based on the information indicating the vehicle mode MD obtained from the mode identification unit 30D. For example, when the vehicle mode MD is the first vehicle mode MD1, the arbitration unit 30B refers to the first arbitration rule RL1 associated with the first vehicle mode MD1.

[0044] Next, the arbitration unit 30B selects one charge / discharge request DS from the multiple charge / discharge requests DS obtained in accordance with the arbitration rule RL it referenced. For example, when the arbitration unit 30B references the first arbitration rule RL1, the arbitration unit 30B selects the first request D1 in which the transmitting device is the input device 40.

[0045] For example, when the arbitration unit 30B refers to the second arbitration rule RL2, the arbitration unit 30B selects the received charge / discharge request DS from among the first request D1, where the transmitting device is the input device 40, and the second request D2, where the transmitting device is the mobile terminal device 70. If both the first request D1 and the second request D2 are received, the arbitration unit 30B selects the charge / discharge request DS with the earlier control start time t.

[0046] For example, when the arbitration unit 30B refers to the third arbitration rule RL3, the arbitration unit 30B selects the third request D3 in which the source device is the charging device 60. For example, when the arbitration unit 30B refers to the fourth arbitration rule RL4, the arbitration unit 30B selects the fourth request D4 in which the source device is the server 80.

[0047] Next, the arbitration unit 30B determines whether the vehicle mode MD identified by the mode identification unit 30D is a discharge-prohibited mode or a discharge-allowed mode. If the identified vehicle mode MD is a discharge-prohibited mode, the arbitration unit 30B determines, as the arbitration result, that the selected first request D1 includes a discharge request DCH, and sets the control request DC to be a non-requested NC, meaning neither charging nor discharging occurs during the period in which the discharge request DCH is made. If the vehicle mode MD identified by the mode identification unit 30D is a discharge-allowed mode, the arbitration unit 30B determines, as the arbitration result, that the selected charge / discharge request DS is a control request DC, even if the selected charge / discharge request DS includes a discharge request DCH.

[0048] <Effects and Effects of the Embodiment> (1) In the above embodiment, for example, when the server 80 is performing charge / discharge control, after the server 80 outputs a fourth request D4, the user of the vehicle 20 may operate the input device 40, causing the input device 40 to output a first request D1. Also, for example, after the user of the vehicle 20 operates the mobile terminal device 70, causing the mobile terminal device 70 to output a second request D2, which is a reservation request, the user of the vehicle 20 may operate the charging device 60, causing the charging device 60 to output a third request D3. In this way, the control device 30 acquires multiple charge / discharge requests DS.

[0049] In this case, in the above embodiment, the arbitration unit 30B refers to the arbitration rule RL and arbitrates the multiple charge / discharge requests DS acquired by the acquisition unit 30A based on the transmitting device. Then, the output unit 30C outputs a control signal MS to the battery 23 to the charge / discharge unit 22 based on the control request DC which is the result of the arbitration by the arbitration unit 30B.

[0050] Therefore, the control device 30 controls the battery 23 based on the control request DC, which is the result of arbitration based on the device that transmitted the charge / discharge request DS. In other words, the battery 23 is not controlled based on a charge / discharge request DS obtained from a device not intended by the user. Thus, the control device 30 can suppress the control of the battery 23 based on a charge / discharge request DS from a device not intended by the user.

[0051] (2) The control device 30 stores arbitration rules RL associated with each of the multiple vehicle modes MD. The arbitration unit 30B arbitrates by selecting one charge / discharge request DS from among multiple charge / discharge requests DS according to the arbitration rule RL associated with the vehicle mode MD identified by the mode identification unit 30D. Therefore, the arbitration unit 30B can control the arbitration result for each vehicle mode MD.

[0052] (3) The arbitration rule RL indicates the device that sent the charge / discharge request DS that is prohibited from being selected. Therefore, the control device 30 can prevent the battery 23 from being controlled based on the charge / discharge request DS that is prohibited from being selected.

[0053] (4) Multiple vehicle modes MD include a discharge-prohibition mode and a discharge-permitting mode. When the vehicle mode MD identified by the mode identification unit 30D is the discharge-prohibition mode, the arbitration unit 30B, if the selected charge / discharge request DS includes a discharge request DCH, sets the control request DC as non-requested NC for the period during which the discharge request DCH is made as the arbitration result. Therefore, when the control device 30 is arbitrated according to the arbitration rule RL associated with the discharge-prohibition mode, it can suppress the discharge control of the battery 23 even if a discharge request DCH is made.

[0054] (5) The charge / discharge request DS is a reservation request. The mediation unit 30B mediates multiple charge / discharge request DS acquired by the acquisition unit 30A during periods when the battery 23 is not being charged or discharged. When a reservation request is made, multiple charge / discharge request DS can be input to the control device 30 without the user of the vehicle 20 having to perform simultaneous operations. Therefore, the above effect (1) is more easily obtained.

[0055] <Example of changes> The above embodiment can be implemented with the following modifications. The above embodiment and the following modifications can be combined with each other to the extent that they do not contradict each other technically.

[0056] The method by which the mode identification unit 30D identifies the vehicle mode MD is not limited to the example of the above embodiment. For example, the mode identification unit 30D may determine the vehicle mode MD based on the driving state of the vehicle 20. Specifically, when the vehicle 20 is driving, it may be identified as the fourth vehicle mode MD4. Also, when the position information of the vehicle 20 is within a specified distance from the position information of the charging device 60, it may be identified as the third vehicle mode MD3. Furthermore, the number of vehicle modes MD is not limited to the example of the above embodiment.

[0057] The control device 30 does not need to store arbitration rules RL associated with multiple vehicle modes MD. Multiple vehicle modes MD do not need to include a discharge prohibition mode and a discharge permitting mode. The control device 30 does not need to have a mode identification unit 30D. The control device 30 may store only one arbitration rule RL regardless of the vehicle mode MD. In this case, the arbitration unit 30B only needs to arbitrate according to the one arbitration rule RL.

[0058] The arbitration unit 30B does not need to arbitrate multiple charge / discharge requests DS according to the arbitration rule RL. The arbitration unit 30B only needs to arbitrate multiple charge / discharge requests DS based on the transmitting device at a minimum.

[0059] The arbitration unit 30B does not have to set the discharge request DCH among the charge / discharge requests DS as a control request DC that does not charge or discharge. In other words, the arbitration unit 30B may arbitrate by simply selecting one charge / discharge request DS from among multiple charge / discharge requests DS. Alternatively, for example, the arbitration unit 30B may select two charge / discharge requests DS from among multiple charge / discharge requests DS, and then select the charge / discharge request DS from the two selected charge / discharge requests DS that starts charging control from the earlier time t.

[0060] The arbitration rule RL does not have to indicate the device that sent the charge / discharge request DS that prohibits selection. For example, the arbitration rule RL may indicate the device that sent the charge / discharge request DS that prioritizes selection.

[0061] The charge / discharge request DS and control request DC are not limited to combinations of charge request CH, discharge request DCH, and non-request NC. For example, the charge / discharge request DS and control request DC may be a charge request CH regardless of the time period.

[0062] For example, the charge / discharge request DS and the control request DC may also request the amount of power to be charged together. Specifically, the charge / discharge request DS may be a reservation request from time t1 to charge with a specified amount of power.

[0063] Furthermore, when multiple charge / discharge requests DS are obtained, if the arbitration unit 30B selects a charge request CH with a different amount of power, it may set the control request DC, which is the result of the arbitration, as a charge request CH with a larger amount of power.

[0064] • The charge / discharge request DS does not have to be a reservation request. In this case, the arbitration unit 30B does not have to arbitrate multiple charge / discharge request DS acquired by the acquisition unit 30A during a period when the battery 23 is not being charged or discharged. For example, the arbitration unit 30B may arbitrate multiple charge / discharge request DS acquired by the arbitration unit 30B during a predetermined period. The predetermined period is, for example, one minute.

[0065] The control device 30 may be configured as a circuit including one or more processors that execute various processes according to a computer program (software). Alternatively, the control device 30 may be configured as a circuit including one or more dedicated hardware circuits, such as application-specific integrated circuits (ASICs), or a combination thereof, that execute at least some of the various processes. The processor includes a CPU and memory such as RAM and ROM. The memory stores program code or instructions configured to cause the CPU to execute processes. Memory, or computer-readable media, includes any available media accessible by a general-purpose or dedicated computer.

[0066] • The multiple devices are not limited to the examples of the above embodiments. For example, the multiple devices may not include some of the devices of the examples of the above embodiments. Also, for example, the multiple devices may include tools for the vehicle 20's maintenance workshop. [Explanation of Symbols]
