Summary of the Invention

Problems to be Solved by the Invention

[0004] In the above-described vehicle, when it is possible to supply power from the vehicle to a predetermined facility as an external load and cooling or heating of the power storage device is required, consideration has not been given to how to perform cooling or heating of the power storage device. If cooling or heating of the power storage device is constantly performed by power supply from the power storage device, the usage frequency of the power storage device is high, and there is a possibility that deterioration of the power storage device is promoted.

[0005] The main object of the present disclosure is to suppress deterioration of the power storage device.

Means for Solving the Problems

[0006] The present disclosure has taken the following means to achieve the above main object.

[0007] [1] The vehicles disclosed herein are A vehicle comprising a power storage device, a temperature control device capable of adjusting the temperature of the power storage device, and a processing device, The processing device determines, when it is possible to supply power from the vehicle to a predetermined facility and cooling or heating of the energy storage device is necessary, whether to cool or heat the energy storage device by supplying power from the energy storage device to the temperature control device, or to cool or heat the energy storage device using the energy of the predetermined facility. This is the gist of it.

[0008] In the vehicle of this disclosure, the processing unit determines whether to cool or heat the energy storage device by supplying power from the energy storage device to the temperature control device, or by using the energy of the designated facility, when the vehicle can supply power to a designated facility and cooling or heating of the energy storage device is necessary. This suppresses the deterioration of the energy storage device compared to when the energy storage device is constantly cooled or heated by supplying power from the energy storage device to the temperature control device when cooling or heating of the energy storage device is necessary. This is considered particularly useful for vehicles parked for long periods in the parking lot of a designated facility. When the processing unit determines that it will cool or heat the energy storage device by supplying power from the energy storage device to the temperature control device, it may also activate the temperature control device using power supplied from the energy storage device. Furthermore, when the processing unit determines that it will cool or heat the energy storage device using the energy of the designated facility, it may also notify the designated facility of this decision.

[0009] [2] In the vehicle of the present disclosure (the vehicle described in [1] above), the cooling or heating of the energy storage device using the energy of the predetermined facility may be the cooling or heating of the energy storage device by supplying power from the predetermined facility to the temperature control device. Alternatively, the heating of the energy storage device using the energy of the predetermined facility may be the heating of the energy storage device using the waste heat of the predetermined facility.

[0010] [3] In the case of the vehicle in this instance (the vehicle described in [2] above), the processing device may determine to cool or heat the energy storage device by supplying power from the energy storage device to the temperature control device when the vehicle is able to supply power to the predetermined facility and cooling or heating of the energy storage device is required, and the surplus amount of the power generation related value related to the power generated by the predetermined facility relative to the power consumption related to the power consumption of the predetermined facility is less than a threshold, and when the surplus amount is equal to or greater than the threshold, the processing device may determine to cool or heat the energy storage device by supplying power from the predetermined facility to the temperature control device. In this way, it is possible to determine, based on the surplus amount, whether to cool or heat the energy storage device by supplying power from the energy storage device to the temperature control device, or to cool or heat the energy storage device by supplying power from the predetermined facility to the temperature control device. Here, "consumption related value" includes not only power consumption, but also the power demand in the first predetermined time up to the present and the predicted power demand value for the second predetermined time from the present. "Power generation-related values" include not only the power generated, but also the amount of power generated during the first predetermined time period up to the present, and the predicted amount of power generated during the second predetermined time period from the present. "Surplus" includes surplus power generated, surplus power generated, and the predicted amount of surplus power generated, as described later.

[0011] [4] In a vehicle of the present disclosure (a vehicle as described in any of [1] to [3] above), the processing device may determine whether cooling or heating of the energy storage device is necessary based on the temperature of the energy storage device when the vehicle is not supplying power to the predetermined facility and / or during power supply.

[0012] [5] In a vehicle of the present disclosure (a vehicle as described in any of [1] to [4] above), the processing device may set the allowable energy storage ratio range of the energy storage devices of the one or more charging / discharging vehicles to a first range when the difference between a power demand-related value related to the power demand of the predetermined facility and a power generation-related value related to the amount of power generated by the predetermined facility is within the range of the total charging / discharging capacity of the energy storage devices of one or more charging / discharging vehicles, including the vehicle itself, which are capable of exchanging power with the predetermined facility. When the difference is outside the range of the total charging / discharging capacity, the allowable energy storage ratio range of the energy storage devices of the one or more charging / discharging vehicles to a second range which is wider than the first range. Therefore, when the difference is within the range of the total charging / discharging capacity, the allowable energy storage ratio range is set to a first range, which suppresses the deterioration of the energy storage devices compared to when the allowable energy storage ratio range is set to a second range. Furthermore, when the difference value is outside the range of the total charging and supplying capacity, the allowable energy storage ratio range is set to the second range, making it easier to cover the difference value through the exchange of power between the designated facility and the vehicle compared to when the allowable energy storage ratio range is set to the first range. Here, "power demand-related values" include not only the power demand in the first predetermined time up to the present, but also the predicted power demand for the second predetermined time from the present. "Power generation-related values" include not only the power generated in the first predetermined time up to the present, but also the predicted power generation for the second predetermined time from the present. "Difference value" includes the surplus power generation, surplus power demand, predicted surplus power generation, and predicted surplus power demand, which will be described later.

[0013] [6] In a vehicle of the present disclosure (a vehicle as described in any of [1] to [5] above), the processing device may, when a first ratio obtained by dividing the total power supply capacity of the energy storage devices of one or more charging / discharging vehicles, including the vehicle itself, by a power demand-related value related to the power demand of the predetermined facility is less than a first ratio threshold, the processing device may limit the power supplied when the energy storage devices of the charging / discharging vehicles supply power to the predetermined facility compared to when the first ratio is equal to or greater than the first ratio threshold; and when a second ratio obtained by dividing the total charging capacity of the energy storage devices of one or more charging / discharging vehicles by a power generation-related value related to the amount of power generated at the predetermined facility is less than a second ratio threshold, the processing device may limit the power supplied when the energy storage devices of the charging / discharging vehicles are charged by power supplied from the predetermined facility compared to when the second ratio is equal to or greater than the second ratio threshold. Therefore, when the first ratio is less than the first ratio threshold, the power supply is limited compared to when the first ratio is equal to or greater than the first ratio threshold, and when the second ratio is less than the second ratio threshold, the charging power is limited compared to when the second ratio is equal to or greater than the second ratio threshold, thus suppressing the deterioration of the energy storage device. As mentioned above, "power demand-related values" include not only power demand but also power demand forecast values. "Power generation-related values" include not only power generation but also power generation forecast values.

[0014] [7] The facilities specified in this disclosure are: A predetermined facility equipped with a processing device, The processing device is capable of supplying power to the predetermined facility from a vehicle equipped with a power storage device and a temperature control device capable of adjusting the temperature of the power storage device, and when cooling or heating of the power storage device is required, it determines whether to cool or heat the power storage device by supplying power from the power storage device to the temperature control device, or to cool or heat the power storage device using the energy of the predetermined facility. This is the gist of it.

[0015] In the designated facility of this disclosure, the processing device can supply power to the designated facility from a vehicle equipped with a power storage device and a temperature control device capable of adjusting the temperature of the power storage device, and when cooling or heating of the power storage device is required, it determines whether to cool or heat the power storage device by supplying power from the power storage device to the temperature control device, or to cool or heat the power storage device using the energy of the designated facility. This allows the device to determine (select) whether to cool or heat the power storage device by supplying power from the power storage device to the temperature control device, or to cool or heat the power storage device using the energy of the designated facility. As a result, when cooling or heating of the power storage device is required, the deterioration of the power storage device can be suppressed compared to when cooling or heating of the power storage device is constantly performed by supplying power from the power storage device.

[0016] [8] The processing system of this disclosure is A vehicle equipped with an energy storage device, a temperature control device capable of adjusting the temperature of the energy storage device, and a first processing device, A predetermined facility equipped with a second processing device, A processing system comprising, The first or second processing unit determines, when it is possible to supply power from the vehicle to the predetermined facility and cooling or heating of the energy storage device is necessary, whether to cool or heat the energy storage device by supplying power from the energy storage device to the temperature control device, or to cool or heat the energy storage device using the energy of the predetermined facility. This is the gist of it.

[0017] In the processing system of the present disclosure, when the first processing device or the second processing device can supply power from the vehicle to a predetermined facility and cooling or warming of the power storage device is required, it determines whether to cool or warm the power storage device by supplying power from the power storage device to the temperature control device, or to cool or warm the power storage device using the energy of the predetermined facility. Thereby, it is possible to determine (select) whether to cool or warm the power storage device by supplying power from the power storage device to the temperature control device, or to cool or warm the power storage device using the energy of the predetermined facility. As a result, when cooling or warming of the power storage device is required, deterioration of the power storage device can be suppressed as compared with the case where cooling or warming of the power storage device by supplying power from the power storage device is always performed.

Embodiments for Carrying Out the Invention

[0019] Embodiments of the present disclosure will be described with reference to the drawings. FIG. 1 is a schematic configuration diagram of a processing system 10 according to this embodiment. As shown in the figure, the processing system 10 of this embodiment includes an airport facility 20 as a predetermined facility and a plurality of vehicles 40. The plurality of vehicles 40 are parked in the parking lot of the airport facility 20. Further, the plurality of vehicles 40 participate in a virtual power plant (VPP), that is, they can exchange power with the airport facility 20. Note that the number of vehicles 40 participating in the VPP may be one.

[0020] The airport facility 20 includes a power generation system 22, a plurality of facility-side connectors 24, and a facility processing device 30. The power generation system 22 and the plurality of facility-side connectors 24 are connected via a power line 23. Various electrical loads (devices) within the airport facility 20 and the power grid outside the airport facility 20 are also connected to the power line 23.

[0021] The power generation system 22 is configured as a power generation system using solar power and has solar panels, a power storage device, and a converter. The solar panels generate electricity using sunlight. The power storage device is configured as, for example, a lithium-ion secondary battery or a NAS secondary battery and is connected to the same power line together with the solar panels and the converter. The converter converts the DC power from the solar panels and the power storage device into AC power and supplies it to the power line 23. The plurality of facility-side connectors 24 are each configured to be connectable to the vehicle-side connectors 46 of the vehicles 40.

[0022] The facility processing unit 30 comprises a computer 31, a storage device 32, and a communication device 33. The computer 31, the storage device 32, and the communication device 33 are connected to each other via communication lines. The computer 31 has a CPU, ROM, RAM, flash memory, input / output ports, and communication ports. The computer 31 receives input for the power generation Pg of the power generation system 22 and the power consumption Pd of the airport facility 20. The computer 31 controls the power generation system 22. The computer 31 calculates the power generation amount Qg and predicted power generation amount Qges of the power generation system 22, and the power demand Qd and predicted power demand Qdes of the airport facility 20.

[0023] The power generation amount Qg of the power generation system 22 is the power generation amount (electrical energy) of the power generation system 22 during a predetermined time T1 up to the present, and is calculated as the time-integrated value of the power generated by the power generation system 22 Pg during the predetermined time T1 up to the present. The predicted power generation amount Qges of the power generation system 22 is the predicted power generation amount of the power generation system 22 during a predetermined time T2 from the present, and is calculated based on at least one of the following: the power generated by the power generation system 22 Pg, the power generation amount Qg, the current amount of sunlight, temperature, and wind speed, and the predicted amount of sunlight, temperature, and wind speed during the predetermined time T2 from the present.

[0024] The power demand Qd of airport facility 20 is the power demand (amount of electricity consumed) of airport facility 20 during a predetermined time T1 up to the present, and is calculated as the time-integrated value of the power consumption Pd of airport facility 20 during the predetermined time T1 up to the present. The predicted power demand Qdes of airport facility 20 is the predicted power demand of airport facility 20 during a predetermined time T2 from the present, and is calculated based on at least one of the following: the power consumption Pd of airport facility 20, the power demand Qd, the current number of users of airport facility 20, the scheduled arrival and departure times of aircraft at airport facility 20 during the predetermined time T2 from the present, or the predicted number of users of airport facility 20.

[0025] The storage device 32 is configured as a large-capacity storage device such as an SSD or a hard disk. The communication device 33 communicates with the outside of the facility processing device 30, for example, with each vehicle 40.

[0026] Each vehicle 40 is configured as an electric vehicle having a driving motor and an energy storage device 42, a hybrid vehicle having a driving motor, an engine and an energy storage device 42, or a fuel cell vehicle having a driving motor, an energy storage device 42 and a fuel cell. In addition to the energy storage device 42, each vehicle 40 is equipped with a temperature control device 44, a vehicle-side connector 46, a bidirectional charging device 48 and a vehicle processing device 50.

[0027] The energy storage device 42 is configured as, for example, a lithium-ion secondary battery or a nickel-metal hydride secondary battery, and is capable of supplying power to the motor for driving. The temperature control device 44 has a fan and a heater, and cools or heats the energy storage device 42 by selectively operating the fan and heater. The vehicle-side connector 46 is configured to be connectable to the facility-side connector 24 of the airport facility 20.

[0028] The bidirectional charging device 48 is connected to a power line 43 connected to the energy storage device 42, a power line 45 connected to the temperature control device 44, and a power line 47 connected to the vehicle-side connector 46. The bidirectional charging device 48 supplies power from power line 47 to at least one of power line 43 and power line 45, or supplies power from power line 43 to at least one of power line 45 and power line 47. In other words, the operation of the bidirectional charging device 48 allows power to be supplied from one of the airport facilities 20 and the vehicle 40 to the other, and the temperature control device 44 can be operated by power supplied from one of the airport facilities 20 and the energy storage device 42. In this embodiment, the power of power lines 43 and 45 is DC power, and the power of power line 47 is AC power. Therefore, the bidirectional charging device 48 converts between DC power and AC power between power lines 43 and 45 and power line 47.

[0029] The vehicle processing unit 50 comprises a microcomputer (hereinafter referred to as "microcontroller") 51 and a communication device 52. The microcontroller 51 has a CPU, ROM, RAM, flash memory, input / output ports, and communication ports. The microcontroller 51 receives the voltage Vb, current Ib, and temperature Tb of the energy storage device 42 as input. The microcontroller 51 calculates the energy storage ratio (SOC) of the energy storage device 42 based on the current Ib of the energy storage device 42. The microcontroller 51 controls the temperature control device 44 and the bidirectional charging device 48. The ROM or flash memory of the microcontroller 51 stores the first allowable upper and lower limits Smax1, Smin1 and the second allowable upper and lower limits Smax2, Smin2 of the energy storage device 42. The first allowable upper and lower limits Smax1, Smin1 are the upper and lower limits of the allowable energy storage ratio range when the allowable energy storage ratio range of the energy storage device 42 is in the normal range as the first range (for example, the range used when the vehicle 40 is running). The permissible upper and lower limits Smax2 and Smin2 are the upper and lower limits of the permissible charge storage range when the permissible charge storage range of the charge storage device 42 is in an expanded range, which is a second range that is expanded from the normal range. The second permissible upper limit Smax2, the first permissible upper limit Smax, the first permissible lower limit Smin, and the second permissible lower limit Smin2 are set in this order from the largest to the smallest. The communication device 52 communicates with the outside of the vehicle processing device 50, for example, with airport facilities 20 or other vehicles 40.

[0030] Next, the operation of the processing system 10 will be described. Figure 2 is a flowchart showing an example of a first processing routine executed by the facility processing device 30 of the airport facility 20. Figure 3 is a flowchart showing an example of a second processing routine executed by the vehicle processing device 50 of each vehicle 40. These routines are executed repeatedly. They will be explained in order below.

[0031] When the processing routine shown in Figure 2 is executed, the computer 31 of the facility processing unit 30 first inputs the predicted power demand value Qdes for the airport facility 20, the predicted power generation value Qges for the power generation system 22 of the airport facility 20, the energy storage ratio SOC[k] of the energy storage device 42 of each vehicle 40 (k: a value corresponding to each vehicle 40), and the first allowable upper and lower limits Smax1[k], Smin1[k] and the second allowable upper and lower limits Smax2[k], Smin2[k] of the energy storage device 42 of each vehicle 40 (step S100). Here, the predicted power demand value Qdes for the airport facility 20 and the predicted power generation value Qges for the power generation system 22 of the airport facility 20 are input values ​​calculated by the facility processing unit 30. The charge storage ratio SOC[k] of the energy storage device 42 in each vehicle 40, as well as the first allowable upper and lower limits Smax1[k], Smin1[k] and the second allowable upper and lower limits Smax2[k], Smin2[k] of the energy storage device 42 in each vehicle 40, are input from each vehicle 40 via communication.

[0032] Next, the first and second charging capacities Cc1[k], Cc2[k] and the first and second power supply capacities Cd1[k], Cd2[k] for each vehicle 40 are calculated (step S110). Then, the first and second total charging capacities Cct1, Cct2 and the first and second total power supply capacities Cdt1, Cdt2 for all vehicles 40 are calculated (step S120).

[0033] Here, the first and second charging capacities Cc1[k] and Cc2[k] are the charging capacities (allowable charging energy of the energy storage device 42) of each vehicle 40 when the allowable energy storage ratio range of the energy storage device 42 for each vehicle 40 is set to the normal range and the expanded range, respectively. The first and second charging capacities Cc1[k] and Cc2[k] are calculated based on the values ​​ΔSh1[k] and ΔSh2[k] obtained by subtracting the energy storage ratio SOC[k] of the energy storage device 42 from the first and second allowable upper limits Smax1[k] and Smax2[k], respectively. For example, when the value ΔSh1[k] is positive, the first charging capacity Cc1[k] is set by converting the value ΔSh1[k] into energy, and when the value ΔSh1[k] is 0 or less, the first charging capacity Cc1[k] is set to 0. The same applies to the second charging capacity Cc2[k]. The first and second charging capacities Cc1[k] and Cc2[k] of each vehicle 40 may be defined as energy amounts based on the allowable charging energy of the energy storage device 42 and the energy supplied to the temperature control device 44 when cooling or heating of the energy storage device 42 is required.

[0034] The first and second power supply capacities Cd1[k] and Cd2[k] are the power supply capacities (allowable power supply amount from vehicle 40 to airport facilities 20) of each vehicle 40 when the allowable power storage ratio range of the energy storage device 42 of each vehicle 40 is set to the normal range and the expanded range, respectively. The first and second power supply capacities Cd1[k] and Cd2[k] are calculated based on the values ​​ΔSl1[k] and ΔSl2[k] obtained by subtracting the first and second allowable lower limits Smin1[k] and Smin2[k] from the power storage ratio SOC[k] of the energy storage device 42, respectively. For example, when the value ΔSl1[k] is positive, the first power supply capacity Cd1[k] is set by converting the value ΔSl1[k] into energy, and when the value ΔSl1[k] is 0 or less, the first power supply capacity Cd1[k] is set to 0. The same applies to the second power supply capacity Cd2[k]. The first and second power supply capacities Cd1[k] and Cd2[k] of each vehicle 40 may be defined as energy based on the allowable amount of power supplied from the vehicle 40 to the airport facilities 20 and the amount of power supplied to the temperature control device 44 when cooling or heating of the energy storage device 42 is required.

[0035] The first and second total charging capacities Cc1 and Cc2 are the total charging capacity (allowable charging power of the energy storage device 42) of all vehicles 40, respectively, when the allowable charge ratio range of the energy storage device 42 for each vehicle 40 is set to the normal range and the expanded range. The first and second total charging capacities Cct1 and Cct2 are calculated as the cumulative values ​​of the first and second charging capacities Cc1[k] and Cc2[k] of each vehicle 40, respectively. The first and second total power supply capacities Cdt1 and Cdt2 are the total power supply capacity (allowable charging power to the airport facilities 20) of all vehicles 40, respectively, when the allowable charge ratio range of the energy storage device 42 for each vehicle 40 is set to the normal range and the expanded range. The first and second total power supply capacities Cdt1 and Cdt2 are calculated as the sum of the first and second power supply capacities Cd1[k] and Cd2[k] of each vehicle 40, respectively.

[0036] Then, it is determined whether the predicted power demand value Qdes of the airport facility 20 is greater than or equal to the predicted power generation value Qges of the power generation system 22 of the airport facility 20 (step S130). If it is determined that the predicted power demand value Qdes is greater than or equal to the predicted power generation value Qges, it is determined whether the predicted surplus power demand value (Qdes-Qges) obtained by subtracting the predicted power generation value Qges from the predicted power demand value Qdes is within the range of the first total power supply capacity Cdt1 (step S140). This process determines whether all of the predicted surplus power demand value (Qdes-Qges) can be supplied from each vehicle 40 to the airport facility 20, assuming that the allowable storage ratio range of the energy storage device 42 of each vehicle 40 is within the normal range.

[0037] In step S140, when it is determined that the predicted surplus power demand (Qdes-Qges) is within the range of the first total power supply capacity Cdt, the allowable power storage ratio range of the energy storage device 42 of each vehicle 40 is set to the normal range, and it is determined that all of the predicted surplus power demand (Qdes-Qges) can be supplied from each vehicle 40 to the airport facilities 20. At this time, the allowable power storage ratio range of the energy storage device 42 of each vehicle 40 is set to the normal range (step S160), and the first total power supply capacity Cct1,Cdt1 is set to the total power supply capacity Cct,Cdt for use in the processing of steps S200 and S230 described later (step S170).

[0038] If, in step S140, it is determined that the predicted surplus power demand (Qdes-Qges) is outside the range of the first total power supply capacity Cdt, then it is determined that it would be difficult to supply all of the predicted surplus power demand (Qdes-Qges) from each vehicle 40 to the airport facilities 20 if the allowable power storage ratio range of the power storage device 42 of each vehicle 40 is set to the normal range. In this case, the allowable power storage ratio range of the power storage device 42 of each vehicle 40 is expanded (step S180), and the second total power supply capacity Cct2,Cdt2 is set to the total power supply capacity Cct,Cdt (step S190).

[0039] If, in step S130, it is determined that the predicted power demand value Qdes is less than the predicted power generation value Qges, it is determined whether the predicted surplus power generation value (Qges-Qdes), obtained by subtracting the predicted power demand value Qdes from the predicted power generation value Qges, is within the range of the first total charging capacity Cct1 (step S150). This process determines whether it is possible to supply all of the predicted surplus power generation value (Qges-Qdes) from the airport facilities 20 to each vehicle 40, assuming that the allowable storage ratio range of the energy storage device 42 of each vehicle 40 is within the normal range.

[0040] In step S150, when it is determined that the predicted surplus power generation amount (Qges-Qdes) is within the range of the first total charging capacity Cct, the allowable storage ratio range of the energy storage device 42 of each vehicle 40 is set to the normal range, and it is determined that all of the predicted surplus power generation amount (Qges-Qdes) can be supplied from the airport facilities 20 to each vehicle 40. At this time, the allowable storage ratio range of the energy storage device 42 of each vehicle 40 is set to the normal range (step S160), and the first total charging capacity Cct1,Cdt1 is set to the total charging capacity Cct,Cdt (step S170).

[0041] If, in step S150, it is determined that the predicted surplus power generation amount (Qges-Qdes) is outside the range of the first total charging capacity Cdt, then it is determined that it would be difficult to supply all of the predicted surplus power generation amount (Qges-Qdes) from the airport facilities 20 to each vehicle 40 if the allowable storage ratio range of the energy storage devices 42 for each vehicle 40 is set to the normal range. In this case, the allowable storage ratio range of the energy storage devices 42 for each vehicle 40 is expanded (step S180), and the second total charging capacity Cct2,Cdt2 is set to the total charging capacity Cct,Cdt (step S190).

[0042] In step S170 or step S190, when the total charging and supplying capacity Cct,Cdt is set, it is determined whether the first ratio (Qdes / Cdt) obtained by dividing the predicted power demand value Qdes of the airport facility 20 by the total supplying capacity Cdt is greater than or equal to the threshold Rth1 (step S200). Here, the threshold Rth1 is used to determine whether the first ratio (Qdes / Cdt) is sufficiently large. If it is determined that the first ratio (Qdes / Cdt) is greater than or equal to the threshold Rth1, a relatively large value Pd1[k] is set for the allowable discharge power Pd[k] of the energy storage device 42 of each vehicle 40 (step S210). On the other hand, if it is determined that the first ratio (Qdes / Cdt) is less than the threshold Rth1, a value Pd2[k] smaller than the value Pd1[k] is set for the allowable discharge power Pd[k] of the energy storage device 42 of each vehicle 40 (step S220).

[0043] Next, it is determined whether the second ratio (Qges / Cct), obtained by dividing the predicted power generation value Qges of the power generation system 22 by the total charging capacity Cct, is greater than or equal to the threshold Rth2 (step S230). Here, the threshold Rth2 is used to determine whether the second ratio (Qges / Cct) is sufficiently large. If it is determined that the second ratio (Qges / Cct) is greater than or equal to the threshold Rth2, a relatively large value Pc1[k] is set as the allowable charging power Pc[k] of the energy storage device 42 of each vehicle 40 (step S240). On the other hand, if it is determined that the second ratio (Qges / Cct) is less than the threshold Rth2, a value Pc2[k] smaller than the value Pc1[k] is set as the allowable charging power Pc[k] of the energy storage device 42 of each vehicle 40 (step S250).

[0044] Then, the permissible charge ratio range and permissible charge / discharge power Pc[k],Pd[k] of the energy storage device 42 in each vehicle 40 are transmitted to each vehicle 40 (step S260), and this routine ends. In each vehicle 40, the vehicle processing device 50 sets the permissible charge ratio range and permissible charge / discharge power Pc[k],Pd[k] of the energy storage device 42 based on the information received from the airport facility 20.

[0045] The facility processing unit 30 of the airport facility 20 transmits a first request to each vehicle 40 for supplying power from the vehicle 40 to the airport facility 20, and a second request to each vehicle 40 for supplying power from the airport facility 20 to each vehicle 40, based on the relationship (magnitude relationship and absolute value of the difference) between the predicted power demand value Qdes and the predicted power generation value Qges. When the vehicle processing unit 50 of each vehicle 40 receives the first request, it controls the bidirectional charging device 48 so that power is supplied from the vehicle 40 to the airport facility 20 within the allowable ratio range of the energy storage device 42 and within the allowable discharge power range Pd[k]. When the vehicle processing unit 50 of each vehicle 40 receives the second request, it controls the bidirectional charging device 48 so that power is supplied from the airport facility 20 to the vehicle 40 within the allowable ratio range of the energy storage device 42 and within the allowable discharge power range Pc[k].

[0046] In this embodiment, when the predicted surplus power demand (Qdes-Qges) is outside the range of the first total power supply capacity Cdt, or when the predicted surplus power generation (Qges-Qdes) is outside the range of the first total charging capacity Cdt, the allowable power storage ratio range of the power storage device 42 of each vehicle 40 is expanded. As a result, in these cases, compared to when the allowable power storage ratio range is set to the normal range, it becomes easier to meet the predicted surplus power demand (Qdes-Qges) by supplying power from each vehicle 40 to the airport facilities 20, and it also becomes easier to meet the predicted surplus power generation (Qges-Qdes) by supplying power from the airport facilities 20 to each vehicle 40.

[0047] Furthermore, when the predicted surplus power demand (Qdes-Qges) is within the range of the first total power supply capacity Cdt, or when the predicted surplus power generation (Qges-Qdes) is within the range of the first total charging capacity Cdt, the allowable power storage ratio range of the energy storage device 42 for each vehicle 40 is set to the normal range. This makes it possible to suppress the deterioration of the energy storage device 42 even in these cases, compared to when the allowable power storage ratio range is set to the expanded range.

[0048] Furthermore, when the first ratio (Qdes / Cdt) is greater than or equal to the threshold Rth1, a relatively large value Pd1[k] is set for the allowable discharge power Pd[k] of the energy storage device 42 of each vehicle 40, and when the second ratio (Qges / Cct) is greater than or equal to the threshold Rth2, a relatively large value Pc1[k] is set for the allowable charging power Pc[k] of the energy storage device 42 of each vehicle 40. This makes it possible to supply power from each vehicle 40 to the airport facilities 20 and from the airport facilities 20 to each vehicle 40 with relatively large power.

[0049] In addition, when the first ratio (Qdes / Cdt) is less than the threshold Rth1, the allowable discharge power Pd[k] of the energy storage device 42 of each vehicle 40 is set to a value Pd2[k] which is smaller than the value Pd1[k], and when the second ratio (Qges / Cct) is less than the threshold Rth2, the allowable charging power Pc[k] of the energy storage device 42 of each vehicle 40 is set to a value Pc2[k] which is smaller than the value Pc1[k]. This limits the power supplied from each vehicle 40 to the airport facilities 20 and from the airport facilities 20 to each vehicle 40. As a result, the deterioration of the energy storage device 42 can be suppressed.

[0050] Next, the second processing routine in Figure 3 will be described. When this routine is executed, in each vehicle 40, the microcontroller 51 of the vehicle processing unit 50 first receives the power consumption Pd and power generation Pg of the airport facility 20, and the temperature Tb of the energy storage device 42 of the vehicle 40 (step S300). Here, the power consumption Pd and power generation Pg of the airport facility 20 are input from the airport facility 20 via communication. The temperature Tb is input from the value stored in the microcontroller 51.

[0051] Next, it is determined whether the temperature Tb of the energy storage device 42 is greater than or equal to the threshold Tbmin and less than or equal to the threshold Tbmax (step S310). Here, the threshold Tbmin is used to determine whether heating of the energy storage device 42 is necessary, and the threshold Tbmax is used to determine whether cooling of the energy storage device 42 is necessary.

[0052] If, in step S310, it is determined that the temperature Tb of the energy storage device 42 is greater than or equal to the threshold Tbmin and less than or equal to the threshold Tbmax, then it is determined that neither cooling nor heating of the energy storage device 42 is necessary, and this routine is terminated.

[0053] In step S310, if the temperature Tb of the energy storage device 42 is less than the threshold Tbmin, or if it is determined that the temperature Tb is higher than the threshold Tbmax, it is determined that cooling or heating of the energy storage device 42 is necessary. In this case, it is determined whether the surplus power generation (Pg-Pd), obtained by subtracting the power consumption Pd from the power generation Pg, is less than a positive threshold Pth (step S320). Here, the surplus power generation (Pg-Pd) can be positive, zero, or negative. The threshold Pth is used to determine whether the surplus power generation (Pg-Pd) is sufficiently large. The threshold Pth may be a constant value, or it may be a value obtained by dividing a constant value by the number of vehicles 40 participating in the VPP.

[0054] If, in step S320, it is determined that the surplus generated power (Pg-Pd) is less than the threshold Pth, then it is determined that the surplus generated power (Pg-Pd) is not very large. In this case, it is determined to cool or heat the energy storage device 42 by supplying power from the energy storage device 42 of the vehicle 40 (step S330), and the routine is terminated. In this case, the vehicle processing unit 50 controls the bidirectional charging device 48 so that power is supplied from the energy storage device 42 to the temperature control device 44 via the bidirectional charging device 48, and also controls the temperature control device 44 so that the fan or heater of the temperature control device 44 is activated. Furthermore, if the vehicle processing unit 50 receives a first request from the airport facility 20 to supply power from the vehicle 40 to the airport facility 20, it controls the bidirectional charging device 48 so that power is supplied from the energy storage device 42 to the temperature control device 44 and the airport facility 20 via the bidirectional charging device 48. Furthermore, in this case, when the vehicle processing unit 50 receives a second request from the airport facility 20 for supplying power to each vehicle 40 from the airport facility 20, it rejects the second request.

[0055] If, in step S320, it is determined that the surplus generated power (Pg-Pd) is greater than or equal to the threshold Pth, it is determined that the surplus generated power (Pg-Pd) is sufficiently large. In this case, it is determined to cool or heat the energy storage device 42 using power supplied from the airport facility 20 (step S340), and this routine is terminated. In this case, the vehicle processing unit 50 controls the bidirectional charging device 48 so that power is supplied to the temperature control device 44 from the airport facility 20 via the bidirectional charging device 48, and also controls the temperature control device 44 so that the fan or heater of the temperature control device 44 is activated. This makes it possible to effectively utilize the surplus generated power (Pg-Pd) to cool or heat the energy storage device 42. In this case, if the vehicle processing unit 50 receives a second request from the airport facility 20 to supply power to each vehicle 40 from the airport facility 20, it controls the bidirectional charging device 48 so that power is supplied to the energy storage device 42 and the temperature control device 44 from the airport facility 20 via the bidirectional charging device 48. Furthermore, in this case, when the vehicle processing unit 50 receives a first request from the airport facility 20 for supplying power from the vehicle 40 to the airport facility 20, it rejects the first request.

[0056] Figure 4 is an explanatory diagram illustrating an example of the conditions at different times for the generated power Pg and power consumption Pd of the airport facility 20, the temperature Tb of the energy storage device 42 of the vehicle 40, and the power supply when cooling or heating the energy storage device 42. As shown in the figure, when the temperature Tb of the energy storage device 42 is below the threshold Tbmin or above the threshold Tbmax during the time when the power consumption Pd is greater than the generated power Pg, the temperature control device 44 is activated by power supply from the energy storage device 42 to the temperature control device 44 to cool or heat the energy storage device 42. On the other hand, when the temperature Tb of the energy storage device 42 is above the threshold Tbmax during the time when the generated power Pg is somewhat greater than the power consumption Pd, the temperature control device 44 is activated by power supply from the airport facility 20 to the temperature control device 44 to cool the energy storage device 42. This allows for the effective use of surplus generated power (Pg-Pd) to cool the energy storage device 42.

[0057] In the vehicle 40 equipped with the processing system 10 of this embodiment described above, the vehicle processing device 50 determines that if the vehicle 40's energy storage device 42 needs to be cooled or heated and the surplus power generated by the airport facility 20 (Pg-Pd) is less than the threshold Pth, it will cool or heat the energy storage device 42 using power supplied from the vehicle 40's energy storage device 42. On the other hand, if the vehicle 40's energy storage device 42 needs to be cooled or heated and the surplus power generated (Pg-Pd) is equal to or greater than the threshold Pth, it will determine that it will cool or heat the energy storage device 42 using power supplied from the airport facility 20. This makes it possible to effectively utilize the surplus power generated (Pg-Pd) to cool or heat the energy storage device 42. In this way, the cooling or heating of the energy storage device 42 can be performed in a more appropriate manner. As a result, when cooling or heating of the energy storage device 42 is necessary, the deterioration of the energy storage device 42 can be suppressed compared to when the energy storage device 42 is constantly cooled or heated by power supplied from the energy storage device 42. This is considered particularly useful for vehicles 40 that are parked for long periods in the parking lot of the airport facility 20.

[0058] In the embodiment described above, the processing system 10 is capable of cooling or heating the vehicle's energy storage device 42 using power supplied from the airport facility 20. However, the processing system 10 only needs to be capable of cooling or heating the energy storage device 42 using energy from the airport facility 20. For example, the processing system 10 may be capable of heating the vehicle's energy storage device 42 using waste heat from the airport facility 20. Waste heat from the airport facility 20 can be, for example, waste heat generated by power generation in the power generation system 22. Heating the vehicle's energy storage device 42 using waste heat from the airport facility 20 can be done, for example, by heating the parking lot of the airport facility 20 with waste heat, or by blowing air heated by waste heat into the vehicle 40. In this case, when it is necessary to heat the energy storage device 42 of the vehicle 40, the system may determine whether to heat the energy storage device 42 of the vehicle 40 using power supplied from the vehicle 40's energy storage device 42, or to heat the energy storage device 42 using waste heat from the airport facility 20, depending on whether it is possible to heat the energy storage device 42 of the vehicle 40 using waste heat from the airport facility 20. The processing system 10 may also be capable of cooling the energy storage device 42 of the vehicle 40 using snow and ice heat from the airport facility 20. Cooling the energy storage device 42 of the vehicle 40 using snow and ice heat from the airport facility 20 can be done, for example, by cooling the parking lot of the airport facility 20 with snow and ice heat, or by blowing air cooled by snow and ice heat onto the vehicle 40. In this case, when cooling of the vehicle 40's energy storage device 42 is necessary, a decision may be made on whether to cool the vehicle 40's energy storage device 42 using power supplied from the vehicle 40's energy storage device 42, or to cool the energy storage device 42 using the snow and ice heat of the airport facility 20, based on whether or not it is possible to cool the vehicle 40's energy storage device 42 using the snow and ice heat of the airport facility 20.

[0059] In the above-described embodiment, the vehicle processing device 50 of the vehicle 40 determines, when cooling or heating of the vehicle 40's energy storage device 42 is necessary, whether to cool or heat the energy storage device 42 using surplus generated power (Pg-Pd) supplied from the vehicle 40's energy storage device 42, or to cool or heat the energy storage device 42 using power supplied from the airport facility 20. However, surplus power generation amount (Qg-Qd) may be used instead of surplus generated power (Pg-Pd). Alternatively, a predicted value of surplus power generation amount (Qges-Qdes) may be used.

[0060] In the embodiment described above, the second processing routine shown in Figure 3 is executed continuously by the vehicle processing unit 50 of the vehicle 40. However, the second processing routine may be executed only when power is not being supplied from the vehicle 40 to the airport facility 20. Alternatively, it may be executed only while power is being supplied from the vehicle 40 to the airport facility 20.

[0061] In the embodiment described above, the facility processing device 30 of the airport facility 20 sets the allowable storage ratio range of the energy storage device 42 of each vehicle 40 to the normal range or the expanded range based on whether the predicted surplus power demand (Qdes-Qges) is within the range of the first total power supply capacity Cdt, when the predicted power demand Qdes is equal to or greater than the predicted power generation Qges. Furthermore, when the predicted power demand Qdes is less than the predicted power generation Qges, the allowable storage ratio range of the energy storage device 42 of each vehicle 40 is set to the normal range or the expanded range based on whether the predicted surplus power generation (Qges-Qdes) is within the range of the first total charging capacity Cdt. However, when the power demand Qd is equal to or greater than the power generation Qg, the surplus power demand (Qd-Qg) may be used instead of the predicted surplus power demand (Qdes-Qges). Furthermore, when the power demand Qd is less than the power generation amount Qg, the surplus power generation amount (Qg-Qd) may be used instead of the predicted surplus power generation amount (Qges-Qdes). In addition, the facility processing device 30 may, regardless of these, fix the allowable energy storage ratio range of the energy storage device 42 of each vehicle 40 within the normal range or the expanded range.

[0062] In the embodiment described above, the facility processing device 30 of the airport facility 20 sets the allowable discharge power Pd[k] of the energy storage device 42 of each vehicle 40 to value Pd1[k] or value Pd2[k] based on a first ratio (Qdes / Cdt). However, the facility processing device 30 may use a ratio obtained by dividing the power demand Qd of the airport facility 20 by the total power supply capacity Cdt, instead of a ratio obtained by dividing the predicted power demand Qdes of the airport facility 20 by the total power supply capacity Cdt, as the first ratio. Alternatively, the facility processing device 30 may uniformly set the allowable discharge power Pd[k] to value Pd1[k] or value Pd2[k] regardless of the first ratio.

[0063] In the embodiment described above, the facility processing device 30 of the airport facility 20 sets the allowable charging power Pc[k] of the energy storage device 42 of each vehicle 40 to value Pc1[k] or value Pc2[k] based on a second ratio (Qges / Cct). However, the facility processing device 30 may use a ratio obtained by dividing the amount of power generated by the power generation system 22 Qg by the total charging capacity Cct, instead of a ratio obtained by dividing the predicted amount of power generated by the power generation system 22 Qges by the total charging capacity Cct, as the second ratio. Alternatively, the facility processing device 30 may uniformly set the allowable charging power Pc[k] to value Pc1[k] or value Pc2[k] regardless of the second ratio.

[0064] In the embodiment described above, the first processing routine shown in Figure 3 is executed by the facility processing device 30 of the airport facility 20. However, the first processing routine may also be executed by the vehicle processing device 50 of any of the vehicles 40. Alternatively, some of the processing in the first processing routine may be executed by the facility processing device 30, and the remaining processing may be executed by the vehicle processing device 50.

[0065] In the embodiment described above, the second processing routine shown in Figure 4 is executed by the vehicle processing device 50 of each vehicle 40. However, the second processing routine may also be executed for each vehicle 40 by the facility processing device 30 of the airport facility 20.

[0066] In the embodiment described above, the bidirectional charging device 48 of each vehicle 40 is configured to supply DC power to the temperature control device 44. However, the bidirectional charging device 48 may also be configured to supply AC power to the temperature control device 44.

[0067] In the embodiment described above, the power generation system 22 of the airport facility 20 is a solar power generation system. However, the power generation system 22 may be a power generation system that uses renewable energy other than solar power. Examples of renewable energy other than solar power include wind power, hydropower, geothermal energy, solar thermal energy, and biomass. Furthermore, the power generation system 22 may be a power generation system that uses energy other than renewable energy. Examples of energy other than renewable energy include nuclear energy and fossil fuels such as oil, coal, and natural gas. Moreover, the power generation system 22 may be a power generation system that combines at least two of these.

[0068] In the embodiment described above, the designated facility was assumed to be an airport facility 20. However, the designated facility may also be a railway station, a shopping center, a leisure facility, a hospital, a school, a port, or the like.

Surplus power generation, surplus power generation amount, and predicted surplus power generation amount correspond to "surplus amount of power generation-related values", surplus power generation amount, surplus power demand, predicted surplus power generation amount, and predicted surplus power demand amount correspond to "difference value between power demand-related value and power generation amount-related value", and the normal range and expanded range correspond to "first range" and "second range", respectively.
