[0018] The present invention will be described below through embodiments of the invention, but the following embodiments do not limit the scope of the invention according to the claims. Furthermore, not all of the combinations of features described in the embodiments are necessarily essential to the solution of the invention.

[0019] 1 conceptually illustrates a usage pattern of a system 100 in one embodiment. The system 100 includes a power generation device 20, a power control device 40, an integrated management device 50, and a vehicle management device 60. The system 100 is a vehicle management system that manages a vehicle 70a, a vehicle 70b, and a vehicle 70c.

[0020] The power generation device 20, the power control device 40, the integrated management device 50, and the vehicle management device 60 are provided corresponding to the business establishment 10. The business establishment 10 is, for example, a factory. The business establishment 10 may be any business establishment such as a factory, an office, a commercial facility, a station, etc.

[0021] In this embodiment, the vehicles 70a, 70b, and 70c may be collectively referred to as "vehicles 70." The vehicles 70 are equipped with a battery. For example, the vehicles 70 are vehicles equipped with a driving battery that stores driving power for driving. The vehicles 70 are, for example, electric vehicles.

[0022] Vehicle 70 is a vehicle used at business establishment 10. For example, vehicle 70 is a vehicle used by user 80a, user 80b, and user 80c who work at business establishment 10. Specifically, vehicle 70 can be used by user 80a to commute between user 80a's home 91 and business establishment 10, by user 80b to commute between user 80b's home 92 and business establishment 10, and by user 80c to commute between user 80c's home 93 and business establishment 10. In this embodiment, user 80a, user 80b, and user 80c may be collectively referred to as "user 80."

[0023] The power generation device 20 is, for example, a power generation device that uses renewable energy such as a solar power generation device. The power control device 40 adjusts the amount of power received from the power grid according to the power demand at the business establishment 10 and the amount of power generated by the power generation device 20 so as to meet the power demand at the business establishment 10. When a power surplus occurs at the business establishment 10, the power control device 40 charges the battery provided in the vehicle 70 with the surplus power.

[0024] The vehicle management device 60 manages the operation of vehicles 70 at the business establishment 10. The vehicle management device 60 manages which vehicle 70 each user 80 uses to commute to work. The integrated management device 50 arbitrates between the control of the vehicle management device 60 and the control of the power control device 40. For example, the integrated management device 50 controls the vehicle management device 60 to obtain operation information of the vehicle 70 executed by the vehicle management device 60, and provides information for the power control device 40 to determine how to use the battery equipped in the vehicle 70.

[0025] 2 is a schematic diagram showing a scene in which a user 80 uses a vehicle 70 to go home on Friday. In this embodiment, the business establishment 10 operates from Monday to Friday, and the business establishment 10 is not operational on Saturdays and Sundays. Since Saturdays and Sundays are not operational days for the business establishment 10, the demand for electricity at the business establishment 10 is low. Therefore, on Saturdays and Sundays, the power generation device 20 generates electricity, resulting in surplus electricity at the business establishment 10.

[0026] After work ends on Friday, the vehicle management device 60, in cooperation with the integrated management device 50 and the power control device 40, determines that when user 80 returns home, vehicle 70c will not be used, but will instead be kept at the business premises 10 on Saturday and Sunday. For example, the vehicle management device 60, in cooperation with the integrated management device 50 and the power control device 40, creates an operation plan such that on Friday, user 80a will use vehicle 70a to return home, and users 80b and 80c will use one vehicle 70b to return home. In addition, the vehicle management device 60, in cooperation with the integrated management device 50 and the power control device 40, creates an operation plan such that, when user 80a returns to work on Monday of the following week, user 80a will use vehicle 70a to go to work at the business premises 10, and users 80b and 80c will use one vehicle 70b to go to work at the business premises 10. Furthermore, the power control device 40 cooperates with the vehicle management device 60 and the integrated management device 50 to perform control so that the battery of the vehicle 70c is charged using surplus power generated by the power generation device 20 on Saturdays and Sundays.

[0027] According to the system 100, the batteries provided in the vehicles 70 used in the business establishment 10 can be efficiently operated, and surplus power generated on non-working days of the business establishment 10 can be effectively utilized.

[0028] FIG. 3 shows an example of a system configuration for realizing the control functions of the power control device 40, the integrated management device 50, and the vehicle management device 60 that constitute the system 100.

[0029] The power control device 40 includes a processing unit 48 and a storage unit 49. The processing unit 48 includes a prediction unit 42 and a charge / discharge control unit 44. The integrated management device 50 includes a processing unit 58 and a storage unit 59. The processing unit 58 includes a first prediction control unit 51, a second prediction control unit 52, a notification control unit 53, a selection control unit 56, and a charge / discharge control unit 54. The vehicle management device 60 includes a processing unit 68 and a storage unit 69. The processing unit 68 includes a selection unit 66 and a notification unit 63.

[0030] The processing unit 48, the processing unit 58, and the processing unit 68 are each realized by an arithmetic processing device including a processor. The storage unit 49, the storage unit 59, and the storage unit 69 are each realized by including a non-volatile storage medium. The processing unit 48 performs processing using information stored in the storage unit 49. The processing unit 58 performs processing using information stored in the storage unit 59. The processing unit 68 performs processing using information stored in the storage unit 69. The power control device 40, the integrated management device 50, and the vehicle management device 60 may be realized by a computer.

[0031] In this embodiment, the power control device 40, the integrated management device 50, and the vehicle management device 60 are each realized by separate computers. However, in other embodiments, the power control device 40, the integrated management device 50, and the vehicle management device 60 may be realized by a single computer. Furthermore, at least some of the functions of the power control device 40, the integrated management device 50, and the vehicle management device 60 may be realized by a server such as a cloud server.

[0032] In the integrated management device 50, the first prediction control unit 51 predicts the amount of surplus power generated at the business establishment 10 on non-working days of the business establishment 10. The second prediction control unit 52 predicts the power capacity that can be stored in each of the multiple vehicles 70 at the business establishment 10 on non-working days. For example, the first prediction control unit 51 causes the power control device 40 to predict the amount of surplus power generated at the business establishment 10 on non-working days of the business establishment 10. Furthermore, the second prediction control unit 52 causes the power control device 40 to predict the power capacity that can be stored in each of the multiple vehicles 70 at the business establishment 10 on non-working days. Note that the amount of surplus power generated at the business establishment may be predicted based on weather information and the amount of power consumed by the business establishment 10 in the past. The power capacity that can be stored in each of the multiple vehicles 70 may be predicted based on the amount of power consumed from batteries provided in the vehicles 70 during commuting.

[0033] In the power control device 40, the prediction unit 42 predicts the amount of surplus power that will be generated at the business establishment 10 on non-working days of the business establishment 10 based on instructions from the first prediction control unit 51. Furthermore, the prediction unit 42 predicts the power capacity that can be stored in each of the multiple vehicles 70 at the business establishment 10 on non-working days based on instructions from the second prediction control unit 52.

[0034] The selection control unit 56 of the integrated management device 50 selects from the plurality of vehicles 70 vehicles to be parked at the business establishment 10 on non-working days based on the amount of surplus electricity generated at the business establishment 10 on non-working days and the electricity capacity that can be stored in each of the plurality of vehicles 70 at the business establishment 10 on non-working days. For example, the selection control unit 56 causes the vehicle management device 60 to select from the plurality of vehicles 70 vehicles to be parked at the business establishment 10 on non-working days. In the vehicle management device 60, the selection unit 66 selects vehicles to be parked at the business establishment 10 on non-working days.

[0035] The selection control unit 56 may select from the plurality of vehicles 70 a number of vehicles corresponding to the amount of surplus electricity generated at the business establishment 10 on non-working days, based on the amount of surplus electricity generated at the business establishment 10 on non-working days and the power capacity that each of the plurality of vehicles 70 can store at the business establishment 10 on non-working days. For example, the selection control unit 56 may cause the vehicle management device 60 to select from the plurality of vehicles 70 a number of vehicles corresponding to the amount of surplus electricity generated at the business establishment 10 on non-working days. In the vehicle management device 60, the selection unit 66 may select a number of vehicles corresponding to the amount of surplus electricity generated at the business establishment 10 on non-working days.

[0036] The charge / discharge control unit 54 adjusts the amount of charge / discharge to the vehicles 70 to be parked on working days of the business establishment 10 so that the available capacity of the batteries equipped in the vehicles to be parked becomes equal to or less than a predetermined value before the non-working day. For example, the charge / discharge control unit 54 causes the power control device 40 to adjust the amount of charge / discharge to the vehicles 70 to be parked on working days of the business establishment 10. In the power control device 40, the charge / discharge control unit 44 adjusts the amount of charge / discharge to the vehicles 70 to be parked on working days of the business establishment 10 in response to instructions from the charge / discharge control unit 54 so that the available capacity of the batteries equipped in the vehicles to be parked becomes equal to or less than a predetermined value before the non-working day.

[0037] When the remaining capacity of the battery of a vehicle scheduled to be parked on an operating day of the business establishment 10 becomes higher than a predetermined value, the selection control unit 56 of the integrated management device 50 causes another vehicle 70 having a battery with a remaining capacity lower than the predetermined value to be selected from among the plurality of vehicles 70 as a new vehicle scheduled to be parked at the business establishment 10 on a non-operating day. The selection control unit 56 causes the vehicle management device 60 to select another vehicle 70 having a battery with a remaining capacity lower than a predetermined value as a new vehicle scheduled to be parked at the business establishment 10 on a non-operating day. In response to an instruction from the selection control unit 56, the selection unit 66 selects another vehicle 70 having a battery with a remaining capacity lower than a predetermined value from among the plurality of vehicles 70 as a new vehicle scheduled to be parked at the business establishment 10 on a non-operating day.

[0038] When the remaining battery capacity of a vehicle scheduled to be parked on an operating day of the business establishment 10 becomes higher than a predetermined value, the charge / discharge control unit 54 causes the vehicle scheduled to be parked to supply power to another vehicle 70 among the multiple vehicles 70 that has a battery with a remaining capacity lower than a predetermined value. For example, the charge / discharge control unit 54 causes the power control device 40 to supply power from the vehicle scheduled to be parked to another vehicle 70 among the multiple vehicles 70 that has a battery with a remaining capacity lower than a predetermined value. In response to instructions from the charge / discharge control unit 54, when the remaining battery capacity of a vehicle scheduled to be parked on an operating day of the business establishment 10 becomes higher than a predetermined value, the charge / discharge control unit 44 controls the supply of power from the vehicle scheduled to be parked to another vehicle 70 among the multiple vehicles 70 that has a battery with a remaining capacity lower than a predetermined value.

[0039] The notification control unit 53 notifies the user 80 of the vehicle to be stored to connect the vehicle 70 to the power supply system of the business 10 before the non-working day. The notification control unit 53 notifies the vehicle management device 60 to connect the vehicle 70 to the power supply system of the business 10 before the non-working day. In response to an instruction from the notification control unit 53, the notification unit 63 notifies the user 80 to connect the vehicle 70 to the power supply system of the business 10 before the non-working day. The notification unit 63 may notify the mobile terminal of the user 80 to connect the vehicle 70 to the power supply system of the business 10.

[0040] The selection control unit 56 selects, from among the users of the multiple vehicles 70, another vehicle 70 for the user of the vehicle to be parked to commute by ride-sharing on the days before and after the non-working day, based on the commuting routes of the users 80 of the multiple vehicles 70 and the remaining capacity of the batteries of the multiple vehicles 70. For example, the selection control unit 56 causes the vehicle management device 60 to select, from among the users of the multiple vehicles 70, another vehicle 70 for the user of the vehicle to be parked to commute by ride-sharing on the days before and after the non-working day. In response to an instruction from the selection control unit 56, the selection unit 66 selects, from among the users of the multiple vehicles 70, another vehicle 70 for the user of the vehicle to be parked to commute by ride-sharing on the days before and after the non-working day, based on the commuting routes of the users 80 of the multiple vehicles 70 and the remaining capacity of the batteries of the multiple vehicles 70. Information indicating the commuting routes of the users 80 may be stored in advance in the memory unit 69.

[0041] The selection control unit 56 causes the vehicle management device 60 to acquire information indicating a combination of users who wish to ride share among the users of the multiple vehicles 70, and selects other users who can ride share with the user of the vehicle 70 to be parked on the days before and after the non-working day based on the combination of users who wish to ride share. The selection control unit 56 causes the vehicle management device 60 to acquire information indicating a combination of users who wish to ride share among the users of the multiple vehicles 70, and selects other users who can ride share with the user of the vehicle 70 to be parked on the days before and after the non-working day based on the combination of users who wish to ride share. In response to an instruction from the selection control unit 56, the selection unit 66 causes the vehicle management device 60 to acquire information indicating a combination of users who wish to ride share among the users of the multiple vehicles 70, and selects other users who can ride share with the user of the vehicle 70 to be parked on the days before and after the non-working day based on the combination of users who wish to ride share.

[0042] Fig. 4 shows in tabular form the operation schedule of vehicle 70. In particular, the operation schedule in Fig. 4 shows a case where vehicle 70c is selected as a vehicle to be parked at business establishment 10 on Saturdays and Sundays.

[0043] Specifically, vehicle 70a is selected as the vehicle used by user 80a to commute to work both when coming in and when leaving work Monday through Friday. Meanwhile, vehicle 70b is selected as the vehicle used by users 80b and 80c to commute by rideshare when coming in to work on Monday and when leaving work on Friday, and is selected as the vehicle used by user 80b to commute to work when leaving work on Monday, when coming in and when leaving work from Tuesday through Thursday, and when coming in to work on Friday. Vehicle 70c is also selected as the vehicle used by user 80c to commute to work when leaving work on Monday, when coming in and when leaving work from Tuesday through Thursday, and when coming in to work on Friday, and is selected as the vehicle to be kept at business establishment 10 from after leaving work on Friday until before leaving work on the following Monday.

[0044] FIG. 5 shows a schematic diagram of the change over time for each day of the week in the amount of surplus power generated at the business establishment 10 and the change over time for each day of the week in the remaining capacity of the battery provided in the vehicle 70. In FIG.

[0045] Graph 400 shows the change over time in the amount of surplus power generated at business establishment 10 for each day of the week. The amount of power consumed by business establishment 10 on Saturdays and Sundays, which are non-working days for business establishment 10, is smaller than the power consumption range of business establishment 10 during the period from Monday to Friday, which are working days for business establishment 10. Therefore, the difference between the amount of power generated by power generation device 20 and the amount of power consumed by business establishment 10 is larger on non-working days for business establishment 10 than on working days for business establishment 10. Therefore, as shown in graph 400, the surplus power generated at business establishment 10 is generally larger on non-working days for business establishment 10 than on working days for business establishment 10.

[0046] Graph 410 shows the change over time for each day of the week in the remaining capacity of the battery equipped in vehicle 70a. Graph 420 shows the change over time for each day of the week in the remaining capacity of the battery equipped in vehicle 70b. Graph 430 shows the change over time for each day of the week in the remaining capacity of the battery equipped in vehicle 70c. The horizontal axes of graphs 400, 410, 420, and 430 represent the day of the week. The vertical axis of graph 400 represents the amount of surplus power generated at business establishment 10. The vertical axes of graphs 410, 420, and 430 represent the amount of remaining capacity of the batteries equipped in vehicle 70a, vehicle 70b, and vehicle 70c, respectively.

[0047] Graphs 410, 420, and 430 show the changes in remaining capacity when vehicle 70 is operated according to the operation schedule shown in Fig. 4. As shown in graph 410, charge / discharge control unit 54 causes power control device 40 to schedule charging of the battery of vehicle 70a with surplus power from business establishment 10 from Monday to Friday. This allows user 80a to use vehicle 70a for commuting from Monday to Friday.

[0048] Similarly, as shown in graph 420, the charge / discharge control unit 54 causes the power control device 40 to schedule charging of the battery of vehicle 70b with surplus power generated at the business establishment 10 from Monday to Friday. This allows user 80b to use the vehicle for commuting from Monday to Friday. In particular, on Monday, the remaining capacity becomes low due to users 80b and 80c commuting by rideshare, so the charge / discharge control unit 54 causes the power control device 40 to preferentially charge vehicle 70b on Monday.

[0049] As shown in graph 430, the charge / discharge control unit 54 causes the power control device 40 to schedule the remaining battery capacity of vehicle 70c to be equal to or greater than a predetermined remaining capacity value by the time work ends on Friday. For example, the charge / discharge control unit 54 causes the power control device 40 to schedule the remaining battery capacity of vehicle 70c to be equal to or less than a predetermined remaining capacity value by the time work ends on Friday. For example, as shown in graph 430, the charge control unit 54 schedules the charging of vehicle 70c so that the remaining battery capacity of vehicle 70c gradually decreases from the time work ends on Monday to the time work starts on Friday. This makes it possible to charge the battery of vehicle 70c with surplus power generated at business 10 on Saturdays and Sundays.

[0050] FIG. 6 shows the flow of processing for determining a vehicle to be stored.

[0051] In S662, the selection unit 66 acquires information indicating a combination of users who wish to commute by ride-sharing. For example, the selection unit 66 transmits recruitment information to a mobile device used by the user 80, inviting users 80 to commute by ride-sharing. When the user 80 receives the recruitment information on the mobile device, the user 80 sets information indicating other users 80 who wish to commute by ride-sharing. The mobile device of the user 80 transmits applicant information including information indicating the set other users 80 to the vehicle management device 60. As a result, the selection unit 66 acquires information indicating a combination of users who wish to commute by ride-sharing.

[0052] In S664, the selection unit 66 determines a combination of users who are eligible to commute by ride-sharing, based on the applicant information. For example, if user 80b wishes to commute by ride-sharing with user 80c, and user 80c wishes to commute by ride-sharing with user 80b, the selection unit 66 determines the combination of user 80c and user 80b as a combination of users who are eligible to commute by ride-sharing. User pair information indicating the user combination determined by the selection unit 66 is stored in the vehicle management device 60 and is used for operation management of the vehicle 70 and for the notification unit 63 to notify users 80 about ride-sharing.

[0053] In S666, the selection unit 66 selects a vehicle to be stored from among the vehicles 70 used by users 80 who are able to commute by ride-sharing. The selection unit 66 also selects a vehicle 70 in which the user 80 of the vehicle to be stored will ride together. Shared vehicle information indicating the vehicle 70 in which the user 80 of the stored vehicle selected by the selection unit 66 will ride together is stored in the vehicle management device 60, and is used for operational management of the vehicle 70 and for the notification unit 63 to notify the user 80 about the ride-sharing.

[0054] In S668, the vehicle management device 60 transmits to the integrated management device 50 parked vehicle information indicating the identification information of the vehicle to be parked selected in S666.

[0055] In S632, when the selection control unit 56 receives the parked vehicle information, it calculates the total value of the battery capacities of the parked vehicles.

[0056] In S602, the prediction unit 42 predicts the amount of surplus power that will be generated at the business establishment 10 on a non-operating day of the business establishment 10 based on instructions from the first prediction control unit 51. The prediction unit 42 predicts the amount of surplus power that will be generated at the business establishment 10 on a non-operating day based on actual data on past power consumption at the business establishment 10, weather forecasts for the area where the business establishment 10 is located, and the current date and time.

[0057] In S604, the prediction unit 42 calculates the battery capacity required in the business establishment 10. For example, the prediction unit 42 calculates the battery capacity required to store the surplus power amount.

[0058] In S606, the prediction unit 42 transmits to the central managing device 50 request information indicating the battery capacity calculated in S604.

[0059] When the integrated management device 50 receives the request information from the power control device 40, in S634 the selection control unit 56 compares the battery capacity requested by the request information with the total battery capacity of the vehicles to be parked. For example, the selection control unit 56 can calculate the total battery capacity of the vehicles to be parked based on the identification information of the vehicles to be parked and the predetermined stored battery capacity of the vehicles 70.

[0060] In S636, the selection control unit 56 determines whether the total battery capacity of the vehicles to be parked is insufficient for the battery capacity requested by the request information. For example, if the total battery capacity of the vehicles to be parked is equal to or greater than the battery capacity requested by the request information, the selection control unit 56 determines that the total battery capacity of the vehicles to be parked is not insufficient for the battery capacity requested by the request information. If the selection control unit 56 determines that the total battery capacity of the vehicles to be parked is not insufficient for the battery capacity requested by the request information, in S638, the selection control unit 56 confirms the vehicles to be parked, and in S640, transmits response information indicating the identification information of the vehicles to be parked and the total battery capacity of the vehicles to be parked to the power control device 40.

[0061] Upon receiving the response information from the integrated management device 50, in S608, the prediction unit 42 verifies the response information and determines the identification information of the vehicles to be parked and the total battery capacity of the vehicles to be parked. The prediction unit 42 stores information including the total battery capacity of the vehicles to be parked and the identification information of the vehicles to be parked as a parked vehicle database available for use on non-working days. The stored battery information is used to control the charge / discharge control unit 44.

[0062] In addition, if, in S636, the selection control unit 56 determines that the total battery capacity of the vehicles to be parked is insufficient compared to the battery capacity requested by the request information, in S642, it sends request information to the vehicle management device 60 to add more parked vehicles.

[0063] When the vehicle management device 60 receives the request information from the integrated management device 50, in S672, it acquires information indicating a new combination of users who wish to commute by ride-share. For example, similar to S662, the selection unit 66 transmits additional recruitment information to the mobile terminal of the user 80 to recruit additional users 80 who commute by ride-share, and receives additional applicant information from the mobile terminal of the user 80.

[0064] In S674, the selection unit 66 determines a new combination of users who are eligible to commute by ride-sharing based on the additional applicant information. The selection unit 66 also selects a vehicle to be stored from among the vehicles 70 used by users 80 who are eligible to commute by ride-sharing, and selects a vehicle 70 in which the user 80 of the stored vehicle will ride together. User pair information indicating the combination of users determined by the selection unit 66 and shared vehicle information indicating the vehicle 70 in which the user 80 of the stored vehicle selected by the selection unit 66 will ride together are stored in the vehicle management device 60 and used for operational management of the vehicles 70 and for notifying users 80 about ride-sharing.

[0065] In S678, the vehicle management device 60 transmits parked vehicle information indicating the identification information of the parked vehicle selected in S674 to the integrated management device 50. When the integrated control device 50 receives the parked vehicle information from the vehicle management device 60, in S638, it performs processing similar to S634 and S636 to determine the vehicle to be parked.

[0066] FIG. 7 shows the flow of processing on a working day at the business establishment 10.

[0067] In S762, when the user 80 arrives at work, the vehicle management device 60 performs a process for the user 80 to return the vehicle 70 to the business establishment 10. For example, the vehicle management device 60 authenticates the user 80 by referring to a database of employees working at the business establishment 10 (S764), and if the user 80 is authenticated, determines that the user 80 will return the vehicle 70.

[0068] In S766, the vehicle management device 60 refers to a vehicle database that manages the identification information of the vehicle 70, and authenticates the vehicle 70 that the user 80 has returned.

[0069] Once the authentication of the vehicle 70 is complete, in S767, the operation plan database for the vehicle 70 at the business establishment 10 is updated. The integrated management device 50 transmits vehicle information including identification information of the returned vehicle 70, the SoC (State of Charge) of the battery equipped in the vehicle 70, and charging request information until the next time the vehicle 70 is used to the power control device 40 (S768).

[0070] When the power control device 40 receives the vehicle information from the vehicle management device 60, in S702, it refers to the charge / discharge history database to obtain the charge / discharge history of the returned vehicle 70. The charge / discharge history database is a database that stores the charge / discharge history of each vehicle 70. The data of the charge / discharge history database is stored in the memory unit 49.

[0071] In S704, the charge / discharge control unit 44 refers to the parked vehicle database to check whether the returned vehicle 70 corresponds to a vehicle scheduled to be parked. Furthermore, if the returned vehicle 70 corresponds to a vehicle scheduled to be parked, the charge / discharge control unit 44 confirms that the SoC of the battery of the vehicle 70 does not exceed a predetermined value. Here, it is assumed that the SoC of the battery of the returned vehicle 70 does not exceed the predetermined value.

[0072] In S706, the charge / discharge control unit 44 refers to the current charging plan, and updates the charging plan for the vehicle 70 for at least the current day and subsequent operating days of the business establishment 10 based on the current charging plan and the comparison result. In S708, charging of the battery of the vehicle 70 is performed based on the updated charging plan. After performing charging control for the current day, the charge / discharge control unit 44 updates the charge / discharge history database based on the charging history performed on the vehicle 70 for the current day in S708 (S710). Furthermore, in S712, charge state information indicating the SoC of the battery of the vehicle 70 is transmitted to the vehicle management device 60. Note that the charging plan indicates, for example, the amount of charge to be applied to the battery provided in each vehicle 70 on each day of the week. The charging plan is planned by the charge / discharge control unit 44. The charging plan is updated by the charge / discharge control unit 44 every time the vehicle 70 moves. Data on the charging plan is stored in the storage unit 49.

[0073] When the vehicle management device 60 receives the charge state information from the power control device 40, it updates the SoC of the vehicle 70 (S769).

[0074] Next, when the user 80 clocks out, clock-out processing is performed for the vehicle 70 used to clock out. For example, the vehicle management device 60 acquires the identification information of the user 80 clocking out (S772), and then authenticates the user 80 clocking out by referring to the employee database working at the business establishment 10 (S774). If the user 80 is authenticated, it is determined that the user 80 will clock out using the vehicle 70. The employee database is a database that stores the identification information of employees. The data in the employee database is stored in the memory unit 69.

[0075] In S776, the vehicle management device 60 authenticates the vehicle 70 that the user 80 will use to leave work by referring to a vehicle database that manages the identification information of the vehicle 70. The vehicle database is a database that stores the identification information of the vehicle 70, the capacity of the battery provided in the vehicle 70, and the remaining capacity of the battery provided in the vehicle 70 in association with each other. The data in the vehicle database is stored in the memory unit 69.

[0076] In S778, the vehicle management device 60 refers to the operation plan database, compares it with the operation plan, and updates the operation plan database. Also, in S780, the vehicle management device 60 updates the vehicle database. For example, the vehicle management device 60 updates the status of the vehicle 70 used to clock out to "in use." Next, in S782, the vehicle management device 60 completes the authentication process for using the vehicle 70 to clock out.

[0077] FIG. 8 shows the flow of processing on a working day of the business establishment 10. Specifically, FIG. 8 explains the processing when a vehicle 70 returned to the business establishment 10 at the time of work arrival is a vehicle scheduled to be parked, and the SoC of the battery of the returned vehicle 70 exceeds a predetermined value. In particular, FIG. 8 shows the flow of processing when the battery of a vehicle scheduled to be parked is used to charge the battery of another vehicle 70. Note that, among the processing shown in FIG. 8, the same processing as that shown in FIG. 7 is assigned the same reference numeral as that in FIG. 7, and description thereof will be omitted.

[0078] If, in the matching process of S704, it is determined that the vehicle 70 returned to the business establishment 10 is a vehicle scheduled to be stored and that the SoC of the battery of the returned vehicle 70 exceeds a predetermined value, the power control device 40 sends notification information to the integrated management device 50 indicating that the SoC of the vehicle 70 scheduled to be stored exceeds a predetermined value (S805).

[0079] In S832, the integrated management device 50 determines whether the vehicle to be stored can be changed to another vehicle 70. Specifically, in S834, the integrated management device 50 transmits inquiry information to the vehicle management device 60 asking whether the vehicle to be stored can be changed to another vehicle 70. In S880, the vehicle management device 60 determines and processes whether to change the vehicle to be stored. Here, the vehicle management device 60 determines that the vehicle to be stored cannot be changed, and transmits response information to the integrated management device 50 indicating that the vehicle to be stored cannot be changed to another vehicle 70 (S882). The determination of whether the vehicle to be stored can be changed to another vehicle 70 will be described in relation to FIG. 9 etc.

[0080] When the integrated management device 50 receives response information from the vehicle management device 60 in S882 indicating that the vehicle to be parked cannot be changed to another vehicle 70, it sends response information to the power control device 40 indicating that the battery of the vehicle 70 to be parked will be discharged and the battery of the other vehicle 70 will be charged (S836).

[0081] When the power control device 40 receives the response information from the integrated management device 50 (S836), in S806, it acquires the current charging plan and updates the charging plan for the vehicle 70 for at least the current and subsequent operating days of the business establishment 10 based on the current charging plan and the response information received in S836. This charging plan includes a charge / discharge process for discharging the battery of the vehicle 70 that is to be parked and charging the battery of another vehicle 70.

[0082] FIG. 9 shows the flow of processing on an operating day of the business establishment 10. Specifically, FIG. 9 explains the processing when the vehicle 70 returned to the business establishment 10 at the time of work arrival is a vehicle scheduled to be stored, and the SoC of the battery of the returned vehicle 70 exceeds a predetermined value. In particular, FIG. 9 shows the flow of processing when the vehicle scheduled to be stored is changed to another vehicle 70. Note that, among the processing shown in FIG. 9, the same processing as the processing shown in FIG. 8 is assigned the same reference numerals as those assigned in FIG. 8, and description thereof will be omitted.

[0083] If, in the matching process of S704, it is determined that the vehicle 70 returned to the business establishment 10 is a vehicle scheduled to be stored and that the SoC of the battery of the returned vehicle 70 exceeds a predetermined value, the power control device 40 sends notification information to the integrated management device 50 indicating that the SoC of the vehicle 70 scheduled to be stored exceeds a predetermined value (S905).

[0084] In S930, the integrated management device 50 determines whether or not the vehicle to be stored can be changed to another vehicle 70 to the vehicle management device 60. Specifically, in S934, the integrated management device 50 transmits inquiry information as to whether or not the vehicle to be stored can be changed to another vehicle 70.

[0085] When the vehicle management device 60 receives the inquiry information, it refers to the operation plan database and determines whether the vehicle scheduled to be parked can be changed (S980). The vehicle management device 60 determines that the vehicle scheduled to be parked can be changed if there is a vehicle 70 whose SoC is lower than a predetermined value. Specifically, if there is a vehicle 70 whose SoC is lower than a predetermined value, the selection unit 66 selects the vehicle 70 whose SoC is lower than the predetermined value as a new vehicle scheduled to be parked, and updates the operation plan database with the selected vehicle 70 as the vehicle scheduled to be parked. The operation plan database is a database of plans indicating how the vehicle 70 will be used for commuting. The data in the operation plan database is stored in the memory unit 69.

[0086] In S982, the vehicle management device 60 transmits response information to the inquiry information to the integrated management device 50. The response information includes identification information of the vehicle 70 newly selected as a vehicle to be stored. The integrated management device 50 transmits the response information including the identification information of the vehicle 70 newly selected as a vehicle to be stored to the power control device 40 (S936).

[0087] When the power control device 40 receives the response information from the integrated management device 50, the charge / discharge control unit 44 updates the parked vehicle database in S920. In addition, the current charging plan is acquired, and the charging plan for the vehicle 70 for at least the current and subsequent operating days of the business establishment 10 is updated based on the current charging plan and the information on the vehicle to be parked that was newly registered in S920 (S922). The parked vehicle database is a database that stores identification information of the vehicle 70 selected as a vehicle to be parked. The data of the parked vehicle database is stored in the memory unit 49.
