[0014] 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.

[0015] 1 conceptually illustrates a usage form of a system 5 in one embodiment. The system 5 includes a power generation device 80, a plurality of vehicles including a vehicle 10a, a vehicle 10b, a vehicle 10c, a vehicle 10d, and a vehicle 10e, power control devices 40 and 41, an integrated management device 50 and 51, a vehicle management device 60 and 61, a power control device 140, and a server 180.

[0016] The power consumer 70 and the power generation device 80 are connected to a power network 90. ​​The power generated by the power generation device 80 can be supplied to the power consumer 70 through the power network 90. ​​The power network 90 is, for example, an electric power system.

[0017] Vehicles 10a, 10b, 10c, 10d, and 10e are electric vehicles equipped with batteries 12a, 12b, 12c, 12d, and 12e, respectively, that store driving power for traveling the vehicles. In this embodiment, vehicles 10a, 10b, 10c, and 10de may be collectively referred to as "vehicles 10," and batteries 12a, 12b, 12c, and 12d may be collectively referred to as "batteries 12."

[0018] Vehicle 10 is deployed at business establishment 30. Business establishment 30 functions as a base for parking vehicle 10. Vehicle 10 may be, for example, a commercial vehicle, or a vehicle for transporting cargo such as merchandise handled at business establishment 30. Electricity is supplied to business establishment 30 through power network 90.

[0019] The power control device 40, the integrated management device 50, and the vehicle management device 60 are installed in the business establishment 30. The vehicle 10 is installed so as to be able to communicate with the vehicle management device 60 via a mobile communication network or the like. The business establishment 30 has a local power network within the business establishment, and power can be exchanged between the battery 12 equipped in the vehicle 10 and the battery 12 through a charging / discharging device installed in the business establishment 30. In other words, the vehicle 10 can be used for energy management at the business establishment 30. The battery 12 equipped in the vehicle 10 can exchange power with the power network 90 through the power network within the business establishment 30. The power control device 40 controls the charging and discharging of the vehicle 10 deployed in the business establishment 30 so as to at least meet the power demand within the business establishment 30.

[0020] The power control device 40, the integrated management device 50, and the vehicle management device 60 are managed, for example, at the business establishment 30. The power control device 40 and the integrated management device 50 are provided so that they can communicate with each other via a communication line. The integrated management device 50 and the vehicle management device 60 are provided so that they can communicate with each other via a communication line. The integrated management device 50 and the vehicle management device 60 may be provided outside the business establishment 30. The integrated management device 50 and the vehicle management device 60 may be provided so that they can communicate with each other via a communication line such as the Internet. One or both of the integrated management device 50 and the vehicle management device 60 may be realized by a server such as a cloud server.

[0021] The vehicle management device 60 determines the time at which the vehicle 10 departs from and returns to the business premises 30. The integrated management device 50 adjusts the time at which the vehicle 10 departs from and returns to the business premises 30 so as to meet the power demand at the business premises 30. For example, the integrated management device 50 adjusts the time at which the vehicle 10 departs from and returns to the business premises 30 so as to enable peak cutting of power demand at the business premises 30. The vehicle management device 60 manages the vehicle 10 based on the schedule for the vehicle 10 adjusted by the integrated management device 50. The power control device 40 controls the charging and discharging of the battery 12 equipped in the vehicle 10 based on the schedule for the vehicle 10 adjusted by the integrated management device 50.

[0022] The vehicle 10e is deployed at the business establishment 31. The business establishment 31 functions as a base for parking the vehicle 10e. The vehicle 10e may be a commercial vehicle, similar to the vehicle 10, or may be a vehicle for transporting cargo such as merchandise handled at the business establishment 30. Electricity is supplied to the business establishment 31 through a power network 90. ​​The power control device 41, the integrated management device 51, and the vehicle management device 61 are provided at the business establishment 31.

[0023] In the business establishment 31, the power control device 41, the integrated management device 51, and the vehicle management device 61 correspond to the power control device 40, the integrated management device 50, and the vehicle management device 60. The power control device 41, the integrated management device 51, and the vehicle management device 61 perform the same control as the power control device 40, the integrated management device 50, and the vehicle management device 60, except that the controlled object and / or the managed object are the business establishment 31 and / or the vehicle 10e. Therefore, explanations of the control relating to the power control device 41, the integrated management device 51, the vehicle management device 61, and the vehicle 10 will be omitted.

[0024] The power control device 140 communicates with the power control device 40 and the power control device 41 via a communication network 190 and supervises overall power control in the business establishments 30 and 31. For example, the power control device 140 collects information on power supply and demand from the power control device 40 and the power control device 41 and causes the power control device 40 and the power control device 41 to perform control so as to minimize the power cost for the business establishments 30 and 31 as a whole by adjusting the overall power supply and demand including power trading with the power network 90.

[0025] The power control device 140 is connected to the server 180 via a communication network 190. The server 180 is, for example, a server used by a power aggregator. The server 180 performs power trading in the power market. The power control device 140 can provide the server 180 with power resources that are aggregated and stored from the business establishment 30 and the vehicles deployed at the business establishment 30. The power control device 140 provides the power agreed upon by the server 180 by having the power control devices 40 and 41 control the charging and discharging of the batteries of the vehicles deployed at the business establishment 30 and 31. For example, the power control device 140 controls the charging and discharging of the battery 12 by the power control device 40 in response to a demand from the server 180, and provides power according to the demand.

[0026] 2 to 7, etc., the control related to the business establishment 30 will be mainly described. Specifically, the control related to the power control device 40, the integrated management device 50, the vehicle management device 60, and the vehicle 10 will be described. However, the control related to the business establishment 30 can be applied to the control related to the business establishment 31.

[0027] 2 shows an example of the system configuration of the vehicle management device 60. The vehicle management device 60 includes a processing unit 200, a storage unit 280, and a communication unit 290.

[0028] The processing unit 200 controls the communication unit 290. The communication unit 290 is responsible for communication between the vehicle 10 and the integrated management device 50. The processing unit 200 is realized by an arithmetic processing device including a processor. The memory units 280 are each realized by including a non-volatile memory medium. The processing unit 200 performs processing using information stored in the memory units 280. The processing unit 200 may be realized by a microcomputer including a CPU, ROM, RAM, I / O, buses, etc. The vehicle management device 60 may be realized by a computer.

[0029] In this embodiment, the vehicle management device 60 is implemented by a single computer. However, in other embodiments, the vehicle management device 60 may be implemented by multiple computers. At least some of the functions of the vehicle management device 60 may be implemented by one or more servers, such as a cloud server.

[0030] The processing unit 200 includes an acquisition unit 210, a planning unit 220, and a management unit 240. The planning unit 220 includes a selection unit 230.

[0031] The acquisition unit 210 acquires reservation information for reserving the use of a vehicle 10 from among a plurality of vehicles 10. The reservation information includes, for example, selection conditions for selecting the vehicle 10 to be used by the user and information specifying the importance of the selection conditions. The selection conditions include, for example, at least one of conditions for selecting the usage period of the vehicle 10 and conditions for selecting the vehicle type. The storage unit 280 stores the reservation information acquired by the acquisition unit 210.

[0032] The acquisition unit 210 further acquires information indicating the state of charge (SOC) and deterioration level of the battery 12 included in the vehicle 10. The information indicating the deterioration level may be, for example, a state of health (SOH). In addition to the SOH, examples of the information indicating the deterioration level of the battery 12 include an integrated value of the amount of power used by the battery 12.

[0033] The planning unit 220 creates a utilization plan for the vehicles 10 based on the reservation information stored in the storage unit 280. For example, the planning unit 220 creates a vehicle allocation plan indicating which users are to use the vehicles 10 based on the selection conditions stored in the storage unit 280. Specifically, the selection unit 230 included in the planning unit 220 creates the vehicle allocation plan by selecting the vehicles 10 to be used by the users.

[0034] The management unit 240 classifies and manages the multiple vehicles 10 into multiple groups based on a combination of the deterioration levels and charging rates of the multiple batteries provided in the multiple vehicles 10. In the planning unit 220, the selection unit 230 selects, based on the reservation information, vehicles 10 that use batteries 12 for operation from among the vehicles 10 classified into a first group of the multiple groups classified by the management unit 240. At this time, the selection unit 230 prioritizes the selection of vehicles 10 classified into a group with a lower deterioration level as vehicles 10 that use batteries 12 for operation. For example, the selection unit 230 prioritizes the selection of vehicles 10 that use batteries 12 for operation from among vehicles 10 that use batteries 12 for operation from among vehicles 10 that use batteries 12 for operation.

[0035] The communication unit 290 transmits the vehicle dispatch plan to the integrated management device 50. The communication unit 290 may further transmit at least a portion of the reservation information to the integrated management device 50. As will be described later, when the vehicle 10 used by a user is changed due to arbitration of conflicting reservations, the communication unit 290 may transmit a notification to the user who had reserved the changed vehicle 10, indicating that the vehicle 10 has been changed.

[0036] 3 shows an example of the system configuration of the central managing device 50. The central managing device 50 includes a processing unit 300, a storage unit 380, and a communication unit 390.

[0037] The processing unit 300 controls the communication unit 390. The communication unit 390 is responsible for communication between the power control device 140 and the integrated management device 50. The processing unit 300 is realized by an arithmetic processing device including a processor. The storage units 380 are each realized by including a non-volatile storage medium. The processing unit 300 performs processing using information stored in the storage unit 380. The processing unit 300 may be realized by a microcomputer including a CPU, ROM, RAM, I / O, buses, etc. The integrated management device 50 may be realized by a computer.

[0038] In this embodiment, the integrated managing device 50 is realized by including a single computer. However, in other embodiments, the integrated managing device 50 may be realized by multiple computers. At least some of the functions of the integrated managing device 50 may be realized by including one or more servers, such as a cloud server.

[0039] The processing unit 300 includes an acquisition unit 310, an arbitration unit 320, and a management unit 340. The arbitration unit 320 includes a selection unit 330.

[0040] The management unit 340 classifies and manages the multiple vehicles 10 into multiple groups based on a combination of the deterioration levels and charging rates of the multiple batteries 12 provided in the multiple vehicles 10. The selection unit 330 selects a vehicle 10 whose battery 12 is used for receiving and transmitting power to and from the power network from the vehicles 10 classified into a specific group of the multiple groups based on power supply and demand information in the power network. The power network is, for example, a power network within the business 30 and / or the power network 90. ​​The power supply and demand information in the power network 90 may be, for example, information regarding an upward demand response (DR), a downward DR, etc.

[0041] The management unit 340 manages the vehicles 10 by classifying them into multiple groups based on a combination of the deterioration level and charging rate of the battery 12, thereby reducing the computational load required to respond to the supply and demand of electricity in the power network while taking into account the deterioration of the battery 12.

[0042] The selection unit 330 preferentially selects a vehicle 10 classified into a group with a lower degree of deterioration as a vehicle 10 whose battery 12 is to be used for power exchange. Specifically, when it is necessary to supply power from the battery 12 to the power network, the selection unit 330 preferentially selects a vehicle 10 classified into a group with a lower degree of deterioration and a higher charging rate as a vehicle 10 whose battery 12 is to be used for power exchange. On the other hand, when it is necessary to supply power to the battery 12 from the power network, the selection unit 330 preferentially selects a vehicle 10 classified into a group with a lower degree of deterioration and a lower charging rate as a vehicle 10 whose battery 12 is to be used for power exchange.

[0043] The acquisition unit 310 acquires reservation information for reserving the use of a vehicle 10 from among a plurality of vehicles 10. The reservation information includes information indicating whether the battery 12 of the vehicle 10 will be used for (i) power transfer with the power network or (ii) operation of the vehicle 10. The acquisition unit 310 may acquire the reservation information for power transfer with the power network from the power control device 40. The acquisition unit 310 may acquire the reservation information for operation of the vehicle 10 from the vehicle management device 60. For example, the acquisition unit 310 may acquire the reservation information for operation of the vehicle 10 via the vehicle management device 60 and the communication unit 390.

[0044] Based on the reservation information, the selection unit 330 selects, from among the vehicles 10 classified into a first group of the plurality of groups, a vehicle 10 whose battery 12 is used for transferring power to and from the power network. Meanwhile, in the vehicle management device 60, the selection unit 230 selects, from among the vehicles 10 classified into a second group of the plurality of groups, a vehicle 10 whose battery 12 is used for operation of the vehicle 10. Here, the second group is a group whose deterioration level is lower than that of the first group. In other words, the selection unit 230 selects, as the vehicle 10 to be used for operation, a vehicle 10 whose battery 12 has a relatively low deterioration level, and the selection unit 330 selects, as the vehicle 10 whose battery 12 has a relatively high deterioration level, a vehicle 10 whose battery 12 is used for transferring power to and from the power network. Compared to when the battery 12 is used for transferring power to and from the power network, the load on the battery 12 when the vehicle 10 is traveling is greater, and the battery 12 often deteriorates more rapidly. Therefore, by selecting a vehicle 10 equipped with a battery 12 with a relatively low level of deterioration as the vehicle 10 to be used for operation, and selecting a vehicle 10 equipped with a battery 12 with a relatively high level of deterioration as the vehicle 10 whose battery 12 is used to exchange power with the power network, it is possible to prevent the deterioration of the battery 12 of a particular vehicle 10 from progressing.

[0045] 4 shows the execution sequence of the power control device 40, the integrated management device 50, and the vehicle management device 60. The processing in FIG. 4 shows the processing from creating a power plan and vehicle allocation plan for the next day the day before to executing various controls in accordance with the created plan.

[0046] As control related to the power control device 40, in S4010, at least one of the user of the power control device 40 and the power control device 140 sets constraints related to the power plan for the business establishment 30 and notifies the power control device 40. The power control device 140 may set constraints for the business establishment 30 so as to minimize the overall power costs for the business establishments 30 and 31. The user is a person or system that inputs information related to power management at the business establishment 30 to the power control device 40. The constraints are conditions that impose constraints on formulating the power plan. The constraints may include constraints necessary to meet power demand. The constraints include, for example, information on the current amount of power generation, the current amount of power consumption, and power rates. The amount of power generation is, for example, the amount of power generated by the power generation device 80. The amount of power consumption is the amount of power consumed at the business establishment 30. The power rates include the power purchase price and the power selling price. The power purchase price is, for example, a condition regarding the amount charged to the business establishment 30 as compensation for receiving power from the power network 90. ​​The power selling price is, for example, a condition regarding the amount of money that the business establishment 30 receives as compensation for supplying power to the power network 90.

[0047] In S4012, the power control device 40 creates a power plan for the business establishment 30 for the next day. The power plan includes the amount of power consumption for each time period in a day. The power plan determines how much power will be consumed in each time period at the business establishment 30. The amount of power consumption for each time period on the next day may be predicted from environmental information such as weather information for the next day and past performance data. The power plan may include peak shave information for performing peak shaving. The peak shave information may include information indicating how much power consumption should be reduced in which time period at the business establishment 30. The peak shave information may include information indicating how much power the business establishment 30 should receive from outside in which time period.

[0048] The power control device 40 may create an optimal power plan for the business 30. For example, the power control device 40 may create a power plan so that the amount of power received from the power network 90 at the business 30 is minimized. The power control device 40 may create a power plan so that the amount of money charged at the business 30 as compensation for receiving power from the power network 90 is minimized. The power control device 40 may create a power plan so that the amount of money obtained at the business 30 as compensation for supplying power to the power network 90 is maximized. In this way, the power control device 40 creates an optimal power plan as the power plan for the next day at the business 30 based on the constraints. This power plan determines the amount of power that needs to be received from outside during each time period on the next day. The amount of power that needs to be received from outside may be supplied from the battery 12 installed in the vehicle 10 parked at the business 30. The power control device 40 transmits the created power plan to the integrated management device 50.

[0049] As a control for the vehicle management device 60, in S4210, a user inputs reservation information for dispatching the vehicle 10. The contents of the reservation information will be specifically described with reference to FIG. 6. A user of the vehicle management device 60 is a person, system, etc. who uses the vehicle 10. The reservation information includes conditions that may be constraints when formulating a vehicle dispatch plan. The reservation information includes, for example, a departure point and destination, a departure time and an arrival time at the destination, and the type, capacity, and weight of cargo to be loaded on the vehicle 10. The departure point and destination determine from which location to which the vehicle 10 needs to travel. The departure time may be, for example, the time when the vehicle 10 departs from the business premises 30, and the arrival time may be, for example, the time when the vehicle 10 returns to the business premises 30. A time adjustment allowance indicating the amount of time by which the departure time and arrival time of the vehicle 10 can be changed may be set for the departure time and arrival time. The reservation information input in S4210 is transmitted to the vehicle management device 60 and also transmitted to the integrated management device 50 via the vehicle management device 60.

[0050] In S4212, the planning unit 220 of the vehicle management device 60 creates a vehicle allocation plan for the next day at the business establishment 30 based on the constraints notified by the user. For example, the planning unit 220 determines the vehicle 10 to be used for transporting people or cargo, the travel route of the vehicle 10, and the travel speed of the vehicle 10 so as to satisfy the transportation demand determined by the reservation information. The vehicle management device 60 transmits the created vehicle allocation plan to the integrated management device 50. At this time, the vehicle management device 60 transmits information indicating the SOC and SOH of the battery 12 of the vehicle 10 to the integrated management device 50 together with the vehicle allocation plan.

[0051] In S4110 , the acquisition unit 310 of the integrated management device 50 acquires the power plan transmitted from the power control device 40 , and the reservation information and vehicle allocation plan transmitted from the vehicle management device 60 .

[0052] In S4112, the arbitration unit 320 of the integrated management device 50 determines whether the power plan for the business establishment 30 is satisfied when the vehicle 10 is operated according to the vehicle allocation plan. For example, the vehicle allocation plan determines the period during which the vehicle 10 is predicted to be present at the business establishment 30. The arbitration unit 320 determines that the power plan is satisfied if, during a period during which the business establishment 30 needs to be supplied with power from an external source, it is predicted that the vehicle 10 will be able to receive power from the battery 12 equipped in the vehicle 10 present at the business establishment 30 during that period.

[0053] If the arbitration unit 320 determines that the power consumption plan cannot be met when vehicles are dispatched according to the vehicle dispatch plan, it determines how to modify the vehicle dispatch plan so that the power consumption plan can be met. For example, the arbitration unit 320 determines the amount of adjustment to the departure times and arrival times of the vehicles 10 in the vehicle dispatch plan.

[0054] The integrated management device 50 transmits correction information including the determined adjustment amounts of the departure times and return times to the vehicle management device 60. When the planning unit 220 of the vehicle management device 60 receives the correction information from the integrated management device 50, it corrects the vehicle allocation plan formulated in S4212 based on the correction information (S4213). For example, the planning unit 220 corrects the vehicle allocation plan so as to satisfy the reservation information based on the adjustment amounts of the departure times and return times received from the integrated management device 50. The vehicle management device 60 transmits the correction result of the vehicle allocation plan to the integrated management device 50. The integrated management device 50 and the vehicle management device 60 repeat the processes of S4112 and S4213 to determine a feasible vehicle allocation plan. In S4213, the planning unit 220 determines a route for the vehicle 10, and determines whether the departure time and arrival time specified in the reservation information can be met, and whether the vehicle 10 can return to the business establishment 30 without running out of power based on the SOC and power consumption rate of the vehicle 10, thereby determining a feasible vehicle dispatch plan. In addition, in S4112, the arbitration unit 320 may determine that the vehicle dispatch plan is feasible, on the condition that it is determined that a profit can be obtained overall, taking into consideration the amount of power cost reduction for the business establishment 30 that can be obtained when power is exchanged between the battery 12 and the business establishment 30 in accordance with the determined power plan, and the operating cost of the vehicle 10 and the availability rate of the vehicle 10 that are required when the vehicle 10 is operated in accordance with the vehicle dispatch plan.

[0055] Once the vehicle allocation plan is determined, the power control device 40 transmits the arbitration result including the vehicle allocation plan to the power control device 40. Upon receiving the arbitration result from the integrated management device 50, the power control device 40 reflects the arbitration result in the power plan (S4014) and notifies the user of the power plan finalized by reflecting the arbitration result (S4015). In S4016, the user and the power control device 140 execute control in accordance with the notified power plan. In S4018, the user and the power control device 140 execute performance processing related to the execution of the power plan. For example, the user executes a process of collecting and inputting performance data for power management, including performance data on the amount of power consumed in each time period. In S4020, the power control device 40 manages the performance data input by the user and the power control device 140 as history information. The power control device 40 may use the history information managed by the power control device 40 when later formulating a power plan.

[0056] The vehicle management device 60 finalizes the vehicle allocation plan finally determined in S4213 (S4214) and notifies the user of the finalized vehicle allocation plan via the communication unit 290. In S4216, the user controls the operation of the vehicles 10 in accordance with the notified vehicle allocation plan. In S4218, the user performs performance processing related to the execution of the vehicle allocation plan. For example, the user may perform a process of collecting and inputting driving performance data including driving data of each vehicle 10 and the remaining capacity of the battery 12. In S4220, the vehicle management device 60 manages the driving performance data input by the user as history information. Note that the vehicle management device 60 may use the history information managed by the vehicle management device 60 when later formulating a vehicle allocation plan.

[0057] FIG. 5 shows groups classified based on the combination of SOC and SOH of the battery 12.

[0058] The management unit 240 and the management unit 340 classify and manage the vehicles 10 into four groups, group A to group D, based on the SOC of the battery 12. Specifically, group A is a group with an SOC of 95% or more and 100% or less. group B is a group with an SOC of 61% or more and 94% or less. group C is a group with an SOC of 40% or more and 60% or less. group D is a group with an SOC of 39% or less.

[0059] The management unit 240 and the management unit 340 classify and manage the vehicles 10 into four groups, group a to group d, based on the SOH of the battery 12. Group a is a group with an SOH of 81% or more and 100% or less. Group b is a group with an SOH of 61% or more and 80% or less. Group c is a group with an SOH of 31% or more and 60% or less. Group d is a group with an SOH of 30% or less.

[0060] The management unit 240 and the management unit 340 classify and manage the vehicle 10 into one of 16 groups according to the combination of the group to which the SOC of the battery 12 belongs and the group to which the SOH of the battery 12 belongs. As an example, a vehicle 10 equipped with a battery 12 whose SOC is within the range of group B and whose SOH is within the range of group a is classified into group Ba. A vehicle 10 equipped with a battery 12 whose SOC is within the range of group B and whose SOH is within the range of group b is classified into group Bb.

[0061] When selecting a vehicle 10 to be used for receiving and sending power to and from the business establishment 30 or a vehicle 10 to be in operation, the selection unit 230 and the selection unit 330 give priority to selecting from among the vehicles 10 classified into a group with a higher SOH. In other words, when selecting a vehicle 10 to be used for receiving and sending power to and from the business establishment 30 or a vehicle 10 to be in operation, the selection unit 230 and the selection unit 330 give priority to selecting a vehicle 10 with a higher SOH. In other words, as shown in FIG. 5 , the higher the SOH, the higher the selection priority based on SOH.

[0062] As an example, the selection unit 230 may select the vehicle 10 to be used for operation from among the vehicles 10 classified into a group having an SOH of 31% or more. In other words, the selection unit 230 may select the vehicle 10 to be used for operation from among the vehicles 10 classified into a group other than group Ad, group Bd, group Cd, and group Dd.

[0063] When selecting a vehicle 10 to be used for power exchange with the business establishment 30 based on a downward demand response (DR), the selection unit 330 preferentially selects the vehicle 10 to be used for power exchange from among the vehicles 10 classified into a group with a higher SOC. In other words, when selecting a vehicle 10 to be used for power exchange with the business establishment 30 based on a downward DR, the selection unit 330 preferentially selects a vehicle 10 with a higher SOC. In other words, as shown in FIG. 5 , the higher the SOC, the higher the selection priority based on SOC. However, when selecting a vehicle 10 to be used for power exchange with the business establishment 30 based on a downward DR, the selection unit 330 does not select a vehicle 10 belonging to group D as a vehicle 10 to be used for power exchange with the business establishment 30.

[0064] In this way, when selecting a vehicle 10 to be used for power exchange with the business establishment 30 based on the downward DR, the selection unit 330 may select from among the vehicles 10 classified into a group with an SOC of 40% or more. In other words, the selection unit 330 may select a vehicle 10 to be used for power exchange from among vehicles 10 classified into a group other than group Da, group Db, group Dc, and group Dd.

[0065] When selecting a vehicle 10 to be used for power exchange with the business establishment 30 based on the increased DR, the selection unit 330 preferentially selects the vehicle 10 to be used for power exchange from among the vehicles 10 classified into a group with a lower SOC. In other words, when selecting a vehicle 10 to be used for power exchange with the business establishment 30 based on the increased DR, the selection unit 330 preferentially selects a vehicle 10 with a lower SOC. In other words, as shown in FIG. 5 , the lower the SOC, the higher the selection priority based on SOC. However, when selecting a vehicle 10 to be used for power exchange with the business establishment 30 based on the increased DR, the selection unit 330 does not select a vehicle 10 belonging to either group A or group B as a vehicle 10 to be used for power exchange with the business establishment 30.

[0066] In this way, when selecting a vehicle 10 to be used for power transfer with the business establishment 30 based on the increased DR, the selection unit 330 may select from among the vehicles 10 classified into a group with an SOC of 60% or less. In other words, the selection unit 330 may select a vehicle 10 to be used for power transfer from among vehicles 10 classified into group Ca, group Cb, group Cc, group Cd, group Da, group Db, group Dc, or group Dd.

[0067] FIG. 6 shows, in table format, a list of multiple reservation information items stored in the integrated management device 50 and the vehicle management device 60. Each piece of reservation information includes information indicating "user," "time change," "vehicle type change," "vehicle type specification," "departure point," "destination," "departure time," "arrival time," and "stay time." Of the information included in the reservation information, "vehicle type specification," "departure point," "destination," "departure time," "arrival time," and "stay time" are examples of selection conditions for the vehicle 10 used by the user. "Time change" and "vehicle change" are examples of information specifying the importance of the selection conditions.

[0068] "User" is the identification information of the person who uses the vehicle 10.

[0069] "Time change" is information indicating whether or not it is permitted to change the selection conditions related to the usage period. The selection conditions related to the usage period are "departure time," "arrival time," and "stay length," which will be described later. "Not permitted" for "Time change" indicates that it is not permitted to change the selection conditions related to the usage period. "Permitted" for "Time change" indicates that it is permitted to change the selection conditions related to the usage period. "Time change" is an example of information specifying the importance of the selection conditions related to the usage period.

[0070] "Vehicle type change" is information indicating whether it is permitted to change the selection conditions related to the type of vehicle (vehicle type) to be used. The selection conditions related to vehicle type are "vehicle type specification" described below. "Not permitted" for "Vehicle type change" indicates that it is not permitted to change the selection conditions related to vehicle type. "Permitted" for "Vehicle type change" indicates that it is permitted to change the selection conditions related to vehicle type. "Vehicle type change" is an example of information specifying the importance of the selection conditions related to vehicle type.

[0071] "Vehicle type designation" is designated when a specific vehicle type is desired to be used. "Vehicle type designation" is identification information of the vehicle type.

[0072] "Departure point" indicates the departure point of the vehicle 10. "Destination point" indicates the destination of the vehicle 10.

[0073] "Departure time" is the scheduled time when vehicle 10 departs from the departure point. "Arrival time" is the scheduled time when vehicle 10 arrives at the destination. "Stay time" indicates the length of time vehicle 10 will stay at the destination. As an example, "Stay time" in Figure 6 indicates the length of time the vehicle will stay at the destination in minutes. When the destination is a business establishment 30, the reservation information does not include "Stay time."

[0074] In the example of Figure 6, the reservation information for user A indicates that vehicle 10 will be used to depart from the office at 12:45, arrive at branch 1 at 12:55, stay at branch 1 for 10 minutes, depart branch 1 at 13:05, and arrive at business 30 at 13:15. This reservation specifies that changes in time and vehicle type are permitted.

[0075] In the example of Figure 6, the reservation information for user B indicates that the vehicle 10 will be used to depart from the office at 14:30, arrive at customer 1's location at 14:40, stay at customer 1's location for 10 minutes, depart customer 1's location at 14:50, and arrive at business 30 at 15:00. This reservation specifies that changes in time and vehicle type are permitted.

[0076] In the example of Figure 6, the reservation information for user C indicates that vehicle 10d will be used to depart from the office at 15:45, arrive at customer 2's location at 15:55, stay at customer 2's location for 10 minutes, depart customer 2's location at 16:05, and arrive at business 30 at 16:15. This reservation specifies that changes to the time and vehicle type are permitted.

[0077] When a conflict occurs in reservations, the arbitration unit 320 arbitrates the conflicting reservations based on the reservation information. For example, the arbitration unit 320 adjusts the conflicting reservations by adjusting the departure time and arrival time. Furthermore, the selection unit 330 of the arbitration unit 320 adjusts the conflicting reservations by selecting another vehicle 10 to be used by the user. The reservation information may further include, as a selection condition, information indicating a time adjustment allowance that indicates an allowable time for changing the departure time and / or the arrival time. The arbitration unit 320 may adjust the conflicting reservations by adjusting the departure time and / or the arrival time within the time adjustment allowance.

[0078] FIG. 7 shows the vehicle allocation plan and the power consumption plan before arbitration is performed, and the vehicle allocation plan and the power consumption plan after arbitration of the vehicle allocation plan and the power consumption plan is performed.

[0079] Here, it is assumed that vehicles 10a, 10b, and 10c are classified into group Ba, and vehicle 10d is classified into group Bb. The selection unit 230 selects vehicles 10a, 10b, and 10c classified into group Ba as vehicles 10 that should be operated for a relatively long period of time, and selects vehicle 10d as a vehicle 10 that should be operated for a relatively short period of time. In this way, the selection unit 230 selects vehicles 10 with a higher SOH as vehicles 10 that should be operated for a longer period of time.

[0080] 7, in the pre-arbitration vehicle dispatch plan prepared by the vehicle management device 60, vehicle 10a is scheduled to be used from 13:00 to 14:00 and from 15:30 to 16:30, as indicated by reference numerals 601 and 602. Furthermore, vehicle 10b is scheduled to be used from 13:30 to 15:00 and from 15:30 to 16:45, as indicated by reference numerals 603 and 604. Furthermore, vehicle 10c is scheduled to be used from 13:00 to 14:00 and from 14:30 to 15:45, as indicated by reference numerals 605 and 606. Furthermore, as shown by reference numerals 607, 608, and 609, the vehicle 10d is scheduled to be used during the periods of 12:45 to 13:15, 14:30 to 15:00, and 15:45 to 16:15.

[0081] As shown by reference numeral 610 in Fig. 7, the power plan created by the power control device 40 plans to use the battery 12 to supply power to the business establishment 30 from 13:00 to 16:00 in order to cut peak demand at the business establishment 30. Reservations based on the power plan and reservations based on the vehicle allocation plan conflict with each other for any of the vehicles 10a, 10b, 10c, and 10d. Therefore, the arbitration unit 320 arbitrates between the reservations based on the power plan and the reservations based on the vehicle allocation plan as follows.

[0082] Here, in the power plan, the amount of power to be supplied from battery 12 is specified as a selection condition other than the usage period for selecting vehicle 10 to be used, and it is set that changing the time for using vehicle 10 is not permitted (time change: not allowed). In this case, the selection unit 330 of the arbitration unit 320 selects vehicle 10d classified in group Bb as the vehicle 10 to be used for receiving and sending power to and from business establishment 30, on the condition that the specified amount of power can be supplied from battery 12d of vehicle 10d during the specified period, and determines that vehicles 10a, 10b, and 10c classified in group Ba are vehicles 10 to be used for operation.

[0083] As shown in FIG. 6, vehicle type changes are permitted for user A, user B, and user C's reservations for vehicle 10d. Because vehicle 10b has no reservations from 12:45 to 13:15, arbitration unit 320 determines that user A can change the vehicle to be used from 12:45 to 13:15 to vehicle 10b. Similarly, because vehicle 10a has no reservations from 14:30 to 15:00, arbitration unit 320 determines that user B can change the vehicle to be used from 14:30 to 15:00 to vehicle 10a. Similarly, because vehicle 10c has no reservations from 15:45 to 16:15, arbitration unit 320 determines that user C can change the vehicle to be used from 15:45 to 16:15 to vehicle 10c.

[0084] As a result of the above, the arbitration unit 320 changes the vehicle to be used for user A's reservation of vehicle 10d to vehicle 10b as shown by reference numeral 617, changes the vehicle to be used for user B's reservation of vehicle 10d to vehicle 10a as shown by reference numeral 618, and changes the vehicle to be used for user C's reservation of vehicle 10d to vehicle 10c as shown by reference numeral 619. Then, the selection unit 330 selects vehicle 10d as the vehicle to supply power to the business establishment 30 based on the power plan for the period from 1:00 PM to 4:00 PM as shown by reference numeral 620. Then, via the communication unit 290 of the vehicle management device 60, users A, B, and C are notified that the vehicles to be used have been changed to vehicle 10b, vehicle 10a, and vehicle 10c, respectively. This makes it possible to effectively use the battery 12 of vehicle 10 for peak shaving at the business establishment 30 within the range acceptable to users A, B, and C.

[0085] According to the system 5 of this embodiment, it is possible to select a vehicle 10 to be used taking into consideration the SOH. In particular, it is possible to give priority to vehicles 10 with a high SOH for use, thereby preventing the deterioration of the battery 12 of a specific vehicle 10 from progressing. Furthermore, by giving priority to the use of vehicles with a high SOH, the SOH naturally decreases, and the priority of use decreases accordingly. This makes it possible to reduce the deterioration of the batteries 12 of all of the multiple vehicles 10 in a relatively uniform manner. Consequently, it is possible to prevent the lifespan of a specific vehicle 10 from being shortened, and it becomes easier to manage the maintenance intervals of the multiple vehicles 10.

[0086] 8 shows an example of a computer 2000 in which multiple embodiments of the present invention may be embodied in whole or in part. A program installed on the computer 2000 may cause the computer 2000 to function as the system 5 or each part of the system 5 according to an embodiment, or as an apparatus or each part of the apparatus, such as the power control device 40 and the vehicle management device 60, perform operations associated with the system or each part of the system, or the apparatus or each part of the apparatus, and / or perform a process or steps of the process according to an embodiment. Such a program may be executed by the CPU 2012 to cause the computer 2000 to perform specific operations associated with some or all of the processing procedures and blocks of the block diagrams described herein.

[0087] The computer 2000 according to this embodiment includes a CPU 2012 and a RAM 2014, which are interconnected by a host controller 2010. The computer 2000 also includes a ROM 2026, a flash memory 2024, a communication interface 2022, and an input / output chip 2040. The ROM 2026, the flash memory 2024, the communication interface 2022, and the input / output chip 2040 are connected to the host controller 2010 via the input / output controller 2020.

[0088] The CPU 2012 operates according to programs stored in the ROM 2026 and RAM 2014, thereby controlling each unit.

[0089] The communication interface 2022 communicates with other electronic devices via a network. The flash memory 2024 stores programs and data used by the CPU 2012 in the computer 2000. The ROM 2026 stores a boot program and the like executed by the computer 2000 upon activation, and / or programs dependent on the hardware of the computer 2000. The input / output chip 2040 may also connect various input / output units such as a keyboard, mouse, and monitor to the input / output controller 2020 via input / output ports such as a serial port, a parallel port, a keyboard port, a mouse port, a monitor port, a USB port, an HDMI (registered trademark) port, etc.

[0090] The programs are provided via a computer-readable storage medium such as a CD-ROM, a DVD-ROM, or a memory card, or via a network. The RAM 2014, the ROM 2026, or the flash memory 2024 are examples of computer-readable storage media. The programs are installed in the flash memory 2024, the RAM 2014, or the ROM 2026 and executed by the CPU 2012. Information processing described in these programs is read by the computer 2000, and causes cooperation between the programs and the various types of hardware resources described above. An apparatus or a method may be configured by implementing operations or processing of information in accordance with the use of the computer 2000.

[0091] For example, when communication is performed between the computer 2000 and an external device, the CPU 2012 may execute a communication program loaded into the RAM 2014 and instruct the communication interface 2022 to perform communication processing based on the processing described in the communication program. Under the control of the CPU 2012, the communication interface 2022 reads transmission data stored in a transmission buffer processing area provided in a recording medium such as the RAM 2014 or flash memory 2024, transmits the read transmission data to a network, and writes received data received from the network to a reception buffer processing area or the like provided on the recording medium.

[0092] The CPU 2012 may also cause all or a necessary portion of a file or database stored on a recording medium such as the flash memory 2024 to be read into the RAM 2014, and perform various types of processing on the data on the RAM 2014. The CPU 2012 then writes the processed data back to the recording medium.

[0093] Various types of information, such as various types of programs, data, tables, and databases, may be stored on the recording medium and subjected to information processing. The CPU 2012 may perform various types of processing on data read from the RAM 2014, including various types of operations, information processing, conditional judgment, conditional branching, unconditional branching, information search / replacement, etc., as described herein and specified by the instruction sequences of the programs, and write the results back to the RAM 2014. The CPU 2012 may also search for information in a file, database, etc. on the recording medium. For example, if multiple entries each having an attribute value of a first attribute associated with an attribute value of a second attribute are stored on the recording medium, the CPU 2012 may search for an entry that matches a condition specified by the attribute value of the first attribute from among the multiple entries, read the attribute value of the second attribute stored in the entry, and thereby obtain the attribute value of the second attribute associated with the first attribute that satisfies a predetermined condition.

[0094] The above-described programs or software modules may be stored in a computer-readable storage medium on or near the computer 2000. A recording medium such as a hard disk or RAM provided in a server system connected to a dedicated communication network or the Internet can be used as the computer-readable storage medium. The programs stored in the computer-readable storage medium may be provided to the computer 2000 via a network.

[0095] A program installed in the computer 2000 and causing the computer 2000 to function as the integrated managing device 50 may act on the CPU 2012 or the like to cause the computer 2000 to function as each of the components of the integrated managing device 50.

These specific means then perform calculations or processing of information according to the intended use of the computer 2000 in this embodiment, thereby constructing a specific integrated managing device 50 according to the intended use.

[0096] A program installed on the computer 2000 and causing the computer 2000 to function as the vehicle management device 60 may act on the CPU 2012 or the like to cause the computer 2000 to function as each unit of the vehicle management device 60. When the information processing described in these programs is read into the computer 2000, it functions as each unit of the vehicle management device 60, which is a specific means formed by the software and the various hardware resources described above working together. These specific means then perform calculations or processing of information according to the intended use of the computer 2000 in this embodiment, thereby constructing a specific vehicle management device 60 according to the intended use.
