[0041] FIG. 5 is a sequence diagram showing an example of the operation of the information processing system 1. FIG. 5 shows a procedure of the coordinated operation by the server device 10, the vehicle 12, the charging / discharging device 14, and the energy resource 13 other than the charging / discharging device 14. In FIG. 5, various power loads 15 and distributed power sources 16 are collectively treated. The transmission and reception of information by the energy resource 13 in FIG. 5 is performed by a power conditioner, a smart meter, or the like that manages or controls the various power loads 15 and the distributed power sources 16. In addition, in FIG. 5, steps related to various information processing of the server device 10, the vehicle 12, and the charging / discharging device 14 are performed by the respective control units 23, 33, and 43. In addition, steps related to the transmission and reception of various information of the server device 10, the vehicle 12, and the charging / discharging device 14 are performed by the respective control units 23, 33, and 43 transmitting and receiving information to each other via the communication units 21, 31, and 41, respectively. In server device 10, vehicle 12, and charging / discharging device 14, control units 23, 33, and 43 respectively store the information transmitted and received in storage units 22, 32, and 42 as appropriate. Furthermore, control units 33 and 43 of vehicle 12 and charging / discharging device 14 respectively accept input of various information through input units 35 and 45, and output various information through output units 36 and 46.

[0042] The procedure of FIG. 5 may be performed, for example, at any time before the opening of the power purchasing market each day.

[0043] In step S500, the vehicle 12 transmits operation information to the server device 10. The operation information includes date, location information and time, connection time to a charging station, remaining battery level, history of power consumption, etc., guided route, and driver personal information. The operation information is transmitted to the server device at any timing, for example, any time before the start of the power purchasing market on each day.

[0044] In step S502, charging / discharging device 14 transmits power information to server device 10. The power information is a history of the amount of power consumed and the amount of power supplied by charging / discharging device 14, for example, over the most recent one to several days. The amount of power consumed is the amount of power supplied from grid 18 and consumed for charging vehicle 12. The amount of power supplied is the amount of power supplied to energy resource 13 by discharging battery 38 of vehicle 12.

[0045] In step S503, the energy resource 13 transmits power information to the server device 10. The power information is, for example, a history of the power consumption by the power load 15 and the power supply amount by the distributed power source 16 for the most recent one to several days. The power consumption amount is the amount of power supplied from the grid 18 and consumed by the power load 15. The power supply amount is the amount of power supplied to the energy resource 13 by generating power using a power generation device included in the distributed power source 16 or discharging a storage battery.

[0046] In step S504, the server device 10 creates or updates a charge / discharge plan for the vehicle 12 and the charge / discharge device 14, using the information received from the vehicle 12, the charge / discharge device 14, and the energy resource 13. Here, the detailed procedure of step S504 will be described with reference to Figures 6A and 6B.

[0047] 6A and 6B are flow charts showing the operation procedure performed by the control unit 23 of the server device 10 for creating or updating a charge / discharge plan.

[0048] In step S600 of FIG. 6A, the control unit 23 predicts the charging demand for each vehicle 12. The charging demand includes the charging amount, charging timing, and charging location for each vehicle 12. The control unit 23 predicts the charging amount and charging timing for each vehicle 12 based on the operation information using an arbitrary algorithm. For example, the control unit 23 predicts the driving route from the history of location information included in the operation information or a guided route. When making the prediction, the control unit 23 may take into account the characteristics of the day of the week. The driving route is, for example, a route for commuting to work or school, a route for traveling for business, etc. In addition, the control unit 23 derives the power consumption per unit distance from the distance of the past driving route and the transition of the remaining battery charge, and predicts the transition of the remaining battery charge from the distance of the predicted driving route and the most recent remaining battery charge using the result. Furthermore, the control unit 23 derives the remaining battery charge at which the driver determines that charging is necessary (for convenience, referred to as the remaining charge required) from the past connection time to the charging station and the remaining battery charge at that time. Furthermore, the control unit 23 predicts the time when the most recent battery remaining amount will reach the required charging amount as the charging timing, and derives the charging amount for bringing the required charging amount to a full charging state. Then, the control unit 23 derives the position of the charging / discharging device 14 that can be reached from the predicted driving route by the charging timing as the charging location. Alternatively, the control unit 23 may predict the optimal charging amount, charging timing, and charging location using a prediction model obtained by machine learning using the operation information of the vehicle 12 and the power information of the charging / discharging device 14 as teacher data.

[0049] In step S602, the control unit 23 predicts power consumption by the power load 15. The prediction of power consumption includes, for example, power consumption for each time period of one to several hours. The control unit 23 predicts power consumption based on power information from the energy resource 13 using any algorithm. For example, the control unit 23 predicts power consumption by taking into account the past transition of power consumption and day of the week characteristics. The power consumption by the power load 15 is, for example, power that cannot be covered by power from the distributed power source 16 and is supplied from the grid 18 and consumed. Alternatively, the control unit 23 may predict power consumption by the power load 15 using a prediction model obtained by machine learning using the power information from the energy resource 13 as training data.

[0050] In step S604, the control unit 23 creates a power consumption time table. The control unit 23 sums up the charge amount in the charging demand of one or more vehicles 12 and the power consumption amount by the power load 15 for each time period, and creates a power consumption time table for the entire community.

[0051] In step S606, the control unit 23 determines whether or not there is a time period in the power consumption timetable where the power consumption exceeds a standard. The standard is the power that can be consumed for each time period, and is obtained, for example, by dividing the amount of power to be purchased proportionally among the time periods. If the standard is not exceeded in any time period (No in step S606), the control unit 23 proceeds to step S626 in FIG. 6B. On the other hand, if the standard is exceeded in any time period (Yes in step S606), the control unit 23 proceeds to step S608.

[0052] In step S608, the control unit 23 searches for vehicles 12 for which the charging timing or the amount of charge can be changed among the charging demands of the vehicles 12. For example, the control unit 23 simulates the transition of the remaining battery charge when the charging timing is advanced or delayed for each vehicle 12, and determines that the charging timing can be changed if the vehicle can travel on the subsequent travel route with the remaining battery charge after charging, and that the charging timing cannot be changed if the vehicle cannot travel. Here, the travel route for which travel is determined whether or not the vehicle can travel includes, for example, a route to another charging / discharging device 14 in addition to the predicted travel route. Furthermore, the control unit 23 simulates the transition of the remaining battery charge when the amount of charge is changed for each vehicle 12, and determines that the amount of charge can be changed if the vehicle can travel on the subsequent travel route with the changed amount of charge, and that the amount of charge cannot be changed if the vehicle cannot travel.

[0053] If there is no vehicle 12 for which the charging timing or the charging amount can be changed (No in step S610), the control unit 23 proceeds to step S616 in Fig. 6B. On the other hand, if there is a vehicle 12 for which the charging timing or the charging amount can be changed (Yes in step S610), the control unit 23 proceeds to step S612.

[0054] In step S612, the control unit 23 changes the charging timing or the charging amount of the vehicle 12 for which the charging timing or the charging amount is changeable.

[0055] In step S614 in Fig. 6B, the control unit 23 determines whether the exceedance of the standard of the power consumption is resolved in the power consumption timetable after changing the charging timing or the charging amount of the vehicle 12. If the exceedance of the standard is resolved (Yes in step S614), the control unit 23 proceeds to step S626. On the other hand, if the exceedance is not resolved (No in step S614), the control unit 23 proceeds to step S616.

[0056] In step S616, the control unit 23 searches for vehicles 12 that can discharge among the vehicles 12. For example, the control unit 23 simulates the transition of the remaining battery charge when the battery 38 is discharged for each vehicle 12 during a time period in which the power consumption exceeds a reference value. At this time, the control unit 23 executes the simulation using an arbitrary number of patterns of discharge amounts. The control unit 23 determines that the vehicle 12 can discharge if it is capable of traveling the subsequent travel route with the remaining battery charge after discharging, or can travel and charge in another time period, and determines that the vehicle 12 cannot discharge if not. For example, the control unit 23 may shift the peak by temporarily charging power using the remaining capacity space of the battery 38 while securing the remaining battery charge required for traveling the predicted travel route, and discharging the battery 38 at the peak of power consumption of the entire community.

[0057] If there is no vehicle 12 capable of discharging (No in step S618), the control unit 23 proceeds to step S624. On the other hand, if there is a vehicle 12 capable of discharging (Yes in step S618), the control unit 23 proceeds to step S620.

[0058] In step S620, the control unit 23 incorporates a schedule of discharge by the vehicle 12 capable of discharging into the power consumption time table.

[0059] In step S622, control unit 23 determines whether the exceedance of the standard of power consumption has been resolved in the power consumption timetable after the scheduled discharge by vehicle 12 has been incorporated. If the exceedance has not been resolved (No in step S622), control unit 23 proceeds to step S624. On the other hand, if the exceedance of the standard has been resolved (Yes in step S622), control unit 23 proceeds to step S626.

[0060] In step S624, the control unit 23 executes a process for adding purchased power. In this case, the standard in the power consumption timetable is exceeded, and the exceeding of the standard is not resolved even if either or both of the charging timing or the charging amount are changed and / or a discharge schedule is incorporated, so that the control unit 23 executes a process for adding purchased power to cover the excess. This makes it possible to purchase power at a lower cost than when additional power is purchased after the power purchase market ends.

[0061] In step S626, the control unit 23 determines a charge / discharge plan for each vehicle 12 based on the power consumption timetable. The charge / discharge plan for the vehicle 12, i.e., the charge / discharge timing, charge / discharge amount, and charge / discharge location, is determined in any of the following cases: when no exceedance of the standard occurs in the initial power consumption timetable, when an exceedance occurs and the exceedance of the standard is resolved by changing the charge timing or charge amount, or by incorporating a discharge schedule, or when the exceedance of the standard is not resolved and purchased power is added.

[0062] In step S628, the control unit 23 uses the determined charge / discharge plan to update the prediction model for predicting the charging demand of the vehicle 12. By doing so, it is possible to improve the prediction accuracy.

[0063] Returning to FIG. 5, in step S505, the server device 10 transmits information on the charge / discharge plan to the vehicle 12. The charge / discharge plan includes information on the charge / discharge timing, the charge / discharge amount, and the charge / discharge location. The vehicle 12 presents the information on the charge / discharge plan to the driver, thereby encouraging the driver to execute the charge / discharge plan. The vehicle 12 may provide route guidance to the driver by incorporating the charge / discharge timing and the charge / discharge location into the guidance route.

[0064] In step S506, the server device 10 transmits information about the charge / discharge plan to the charge / discharge device 14 specified as the charge / discharge location in the charge / discharge plan. If the charge / discharge location is a parking lot or the like and the charging timing arrives while the vehicle is parked, the server device 10 transmits the charge / discharge plan to the charge / discharge device 14 installed in the parking lot and causes the charge / discharge device 14 to perform charging / discharging in accordance with the charge / discharge plan.

[0065] In step S507, the vehicle 12 and the charging / discharging device 14 charge or discharge the vehicle 12. Step S507 may be performed before or after the end of the power purchase market. For example, when the driver moves the vehicle 12 to a designated charging / discharging location and connects the vehicle 12 to the charging / discharging device 14 at the charging / discharging timing, the vehicle 12 and the charging / discharging device 14 charge or discharge the vehicle 12. The charging / discharging device 14 may notify the driver of the arrival of the charging / discharging timing by outputting an image or sound. Alternatively, when the charging / discharging timing arrives while the vehicle 12 is parked in a parking lot or the like, the driver parks the vehicle 12 with the vehicle 12 connected to the charging / discharging device 14, and the vehicle 12 and the charging / discharging device 14 charge or discharge when the charging / discharging timing arrives.

[0066] The information processing system 1 can execute the procedures of Fig. 5 and Fig. 6A and 6B any number of times, for example, before the power purchasing market ends. Even when the vehicle 12 starts moving and is moving, the server device 10 acquires operation information of the vehicle 12 at any time and updates the predicted charging demand, making it possible to update the charging and discharging plan to one that conforms to the actual power consumption of the vehicle 12. In addition, the vehicle 12 can be charged and discharged multiple times a day, for example. In this way, by leveling out the amount of power consumption required for charging the vehicle 12 and the timing of power consumption, it is possible to avoid a situation in which the power consumed exceeds the power purchased from the grid 18 for the entire community, making it possible to consume more efficiently.

[0067] In addition, server device 10 may create not only a charge / discharge plan for the current day of vehicle 12 but also a charge / discharge plan for the next day and thereafter, and transmit the method of the charge / discharge plan to vehicle 12 and charge / discharge device 14.

[0068] In addition, the server device 10 may obtain information on the power supply margin of the distributed power source 16 as power information from the energy resource 13, and if the peak in power consumption for the entire community cannot be resolved by charging and discharging in the vehicle 12 alone, the server device 10 may send an instruction to supply power to the distributed power source 16.

[0069] In the above-described embodiment, the processing and control programs that regulate the operation of the control unit 33 of the vehicle 12 and the control unit 43 of the charging / discharging device 14 may be stored in the memory unit 22 of the server device 10 or in a memory unit of another server device and downloaded to each device via the network 11, or may be stored in a non-transitory recording and storage medium that is readable by each device and read from the medium by each device.

[0070] In the above, the embodiment has been described based on the drawings and examples, but it should be noted that those skilled in the art can easily make various modifications and corrections based on the present disclosure. Therefore, it should be noted that these modifications and corrections are included in the scope of the present disclosure. For example, the functions included in each means, each step, etc. can be rearranged so as not to be logically inconsistent, and multiple means, steps, etc. can be combined into one or divided into one.
