<Overall configuration of EV management system>
FIG. 1 is a diagram showing an overall configuration example of the EV management system 1 according to the present embodiment. The EV management system 1 according to the present embodiment includes an EV management server 100, a station 200, and an EV 300. The EV300 is an electric vehicle (including a plug-in hybrid vehicle). In other words, the EV 300 is a vehicle that travels using the rechargeable battery 301.
In the present embodiment, the EV management system 1 and the EV management server 100 are used as an example of the information processing system.

The EV management server 100 is a server device that manages the operation of the mobility service of the EV 300. The EV management server 100 is provided, for example, as a server device of a company that provides the mobility service of the EV 300.
Here, the mobility service is a service in which the EV300 is used by the user according to the wishes of the user to earn a profit. For example, the case where the EV300 is used as a taxi or the rental car service of the EV300 is exemplified. Further, for example, a car sharing service, which is a service in which EV300s are shared among users, and a ride sharing service, in which a plurality of users ride together on one EV300, are exemplified.
In the following, as an example of the mobility service, an EV300 such as a rental car service or a car sharing service will be rented out. Further, in the following, a user of EV300 in the mobility service may be simply referred to as a “user”.

Here, the EV management server 100 uses information about the EV 300 vehicle (for example, a vehicle ID assigned to each EV 300 to identify the EV 300, a vehicle model of the EV 300, and an EV 300 for all the EV 300s prepared by the mobility service. Information such as performance) is retained.
Further, the EV management server 100 receives the position information of the EV 300 and the remaining amount of electric energy charged in the EV 300 (SOC (SOC)) from the EV 300 via a network such as the Internet at all times (for example, every 5 minutes) or as needed. Acquire various information such as State Of Charge)).
Further, the EV management server 100 receives a reservation for use of the EV 300 from the user via the user's terminal device or the like.
Then, the EV management server 100 manages the use of the EV 300 by the user and the charging (and discharging) of the EV 300 for each EV 300.

More specifically, for example, when the EV management server 100 uses the EV300 by the user, the usage fee for making the user use the EV300 (hereinafter referred to as "mobility fee") and the EV300 for the user. Manage the schedule to be used. The mobility fee is, for example, a usage fee per hour for each EV300.
Further, for example, the EV management server 100 manages the charging (and discharging) of the EV 300, for example, the remaining amount of electric energy charged in the EV 300, the timing of charging the EV 300, the time for charging the EV 300, and the like.

Further, the EV management server 100 acquires information on the supply and demand of electric power (hereinafter, referred to as “electric power supply and demand information”) from the resource aggregator 400. This electric power supply and demand information includes information on profits or profits obtained when the EV 300 is used to deal with the supply and demand of electric power. In other words, the power supply and demand information is, for example, the supply and demand of a power transmission and distribution company 500, a renewable energy power generation company (for example, a power generation company such as solar power generation and wind power generation) 600, and a retail electricity company 700. Information about incentives obtained by contributing to coordination. When the EV management server 100 acquires the power supply and demand information, the profit obtained by the mobility service (hereinafter referred to as "mobility profit") and the profit obtained by controlling the discharge or charge of the EV 300 according to the power supply and demand information (hereinafter referred to as "mobility profit"). , Called "electricity-related revenue") and identify mobility charges that maximize the sum.

Here, the resource aggregator 400 refers to the demands of each business operator regarding the power supply and demand such as the power transmission and distribution business operator 500, the renewable energy power generation business operator 600, and the retail electric power business operator 700, and the electric power owned by factories, offices, homes, and the like. It is a business operator that adjusts the supply and demand of electricity according to the demands of each business operator and pays compensation to those who cooperated with the demands.
For example, the resource aggregator 400 supplies electric power necessary for frequency adjustment and supply-demand balance adjustment to the power transmission and distribution business operator 500, and plans of business operators such as the renewable energy power generation business operator 600 and the retail electric power business operator 700. The electric power required to reduce the error between the value and the measured value is supplied to each business operator. In order to adjust the supply and demand of electric power, the resource aggregator 400 transmits the electric power supply and demand information and requests the EV management server 100 for the electric power supply and demand.

However, the acquisition destination from which the EV management server 100 acquires the power supply / demand information is not limited to the resource aggregator 400. For example, the EV management server 100 may directly acquire power supply and demand information from each business operator such as a power transmission and distribution business operator 500, a renewable energy power generation business operator 600, and a retail electric power business operator 700.

Further, unless otherwise specified, an example in which the EV management server 100 specifies a mobility charge based on the mobility revenue and the power-related revenue will be described below. However, the present embodiment is not limited to the configuration in which the mobility fee is specified based on the profit. For example, the EV management server 100 may specify the mobility charge based on the profit obtained from the mobility service and the profit obtained by controlling the discharge or charge of the EV 300 according to the power supply / demand information.

The station 200 is a place where the EV 300 can be rented and the EV 300 can be charged (or discharged).
For example, the user receives a loan of EV300 at the station 200. In addition, the user uses the rented EV300 and returns the EV300 to the station 200 after using it. The station 200 for renting the EV 300 and the station 200 for returning the EV 300 may be the same or different.
Further, the station 200 is provided with a charging / discharging facility 201 for charging and discharging the EV 300. When the administrator of the station 200 or the user who uses the EV 300 connects the EV 300 to the charging / discharging equipment 201, power is supplied from the charging / discharging equipment 201 to the EV 300 to charge the EV 300 or discharge the EV 300. Is done.

The EV 300 is a vehicle that travels using the rechargeable battery 301. The EV 300 is connected to the charging / discharging equipment 201 of the station 200 via a charging / discharging plug or the like to charge or discharge. In addition, the on-board unit (not shown) provided in the EV300 communicates with other devices such as the EV management server 100, and charges the EV300 with the position information of the EV300 acquired by GPS (Global Positioning System) or the like. Outputs various information such as the remaining amount of charged power.

In the example shown in FIG. 1, two stations 200 are shown, but the number of stations 200 is not limited to two. The EV management system 1 has a number of stations 200 managed by the EV management server 100. Further, the number of charge / discharge facilities 201 provided in the station 200 is not limited to two. Further, as for the EV300, there are as many EV300s as are prepared by the mobility service. The number of EV300 may be one.

<Hardware configuration of EV management server>
Next, the hardware configuration of the EV management server 100 according to the present embodiment will be described. FIG. 2 is a diagram showing a hardware configuration example of the EV management server 100 according to the present embodiment.

(Read Only Memory) 102 and a RAM (Random Access Memory) 103 used as a program execution area are provided.

Further, the EV management server 100 includes an HDD (Hard Disk Drive) 104 which is a storage area for storing various programs such as an OS (Operating System) and an application, input data for various programs, output data from various programs, and the like. Then, the program stored in the ROM 102, the HDD 104, or the like is read into the RAM 103 and executed by the CPU 101, whereby the function of the EV management server 100 is realized.
Further, the EV management server 100 includes a communication interface (communication I / F) 105 for communicating with the outside, a display mechanism 106 including a video memory, a display, and the like, and an input device 107 such as a keyboard, a mouse, and a touch panel. To be equipped with.

<Functional configuration of EV management server>
Next, the functional configuration of the EV management server 100 according to the present embodiment will be described. FIG. 3 is a diagram showing an example of the functional configuration of the EV management server 100 according to the present embodiment. The EV management server 100 includes a mobility temporary charge setting unit 111, a mobility vehicle utilization rate calculation unit 112, a mobility revenue calculation unit 113, a power supply / demand available number calculation unit 114, a power revenue calculation unit 115, a total revenue calculation unit 116, and a mobility charge output. A unit 117 is provided.

When the mobility temporary charge setting unit 111 acquires the power supply / demand information from the resource aggregator 400 or the like, the mobility temporary charge setting unit 111 sets a temporary mobility charge (hereinafter, referred to as “mobility temporary charge”).
Here, the mobility provisional charge setting unit 111 sets a predetermined number of mobility provisional charges. As will be described later, the predetermined number may be a number that can specify the mobility charge that maximizes the total revenue calculated by the revenue total calculation unit 116. In other words, any number may be sufficient as long as the relationship between the temporary mobility charge and the total revenue calculated by the total revenue calculation unit 116 can be grasped.

The mobility vehicle utilization rate calculation unit 112 calculates the utilization rate of the EV 300 used by the user for each temporary mobility charge. The utilization rate of the EV300 is the ratio of the EV300 that is predicted to be used by the user among all the EV300 prepared by the mobility service. In other words, the utilization rate of EV300 can be said to be an index showing the demand for mobility services.
For example, the correlation between the hourly mobility charge of one EV300 and the utilization rate is predetermined. In this correlation, for example, the lower the mobility charge, the higher the utilization rate of the EV300, and the higher the mobility charge, the lower the utilization rate of the EV300. The mobility vehicle utilization rate calculation unit 112 calculates the utilization rate of the EV 300 for each temporary mobility charge based on this correlation.

The mobility revenue calculation unit 113 calculates the mobility revenue when the EV 300 is used at the utilization rate calculated by the mobility vehicle utilization rate calculation unit 112 for each temporary mobility charge. In other words, the mobility revenue calculation unit 113 calculates the mobility revenue based on the demand of the EV 300 according to the temporary mobility charge.
For example, the mobility revenue calculation unit 113 multiplies the usage fee per hour of the EV300 by the number of EV300s used at the utilization rate calculated by the mobility vehicle utilization rate calculation unit 112, and one unit 1 Calculate mobility revenue per hour.

The electric power supply / supply available number calculation unit 114 calculates the number of EV 300s that can be used for the electric power supply / demand for each temporary mobility charge.
For example, the power supply / demand available number calculation unit 114 sets the EV300 that is not used in the mobility service as the EV300 that can be used for the power supply / demand. More specifically, for example, the power supply / demand available unit calculation unit 114 excludes all EV300s prepared by the mobility service, except for the EV300 used at the utilization rate calculated by the mobility vehicle utilization rate calculation unit 112. Calculate the number of EV300s that can be used for the supply and demand of electric power.

The electric power revenue calculation unit 115 calculates the electric power-related revenue obtained by the EV 300 that can be used for the supply and demand of electric power for each temporary mobility charge. Here, the electric power revenue calculation unit 115 calculates the electric power-related revenue obtained by controlling the discharge or charging of the EV 300 according to the electric power supply and demand information acquired from the resource aggregator 400 or the like for each temporary mobility charge.

For example, the electric power revenue calculation unit 115 acquires the information on the revenue obtained by providing the adjusting power capable of adjusting the supply and demand of electric power in a specific time zone from the electric power supply and demand information from the resource aggregator and the like. Here, the adjusting power is generally called a ΔkW value, and is a value for adjusting the frequency or the like to maintain the quality of electric power. As described above, electric power-related profits can be obtained by providing adjustment power to power transmission and distribution business operators 500, renewable energy power generation business operators 600, retail electricity business operators 700, etc. in accordance with requests from resource aggregators 400 and the like. Be done. Therefore, the electric power revenue calculation unit 115 calculates the electric power supply and demand revenue in consideration of the number of EV300s calculated by the electric power supply and demand available unit calculation unit 114 with respect to the electric power supply and demand information.

The total revenue calculation unit 116 calculates the total of the mobility revenue calculated by the mobility revenue calculation unit 113 and the power-related revenue calculated by the power revenue calculation unit 115 for each temporary mobility charge.

The mobility charge output unit 117 outputs information on the mobility charge when the total revenue calculated by the total revenue calculation unit 116 is maximum. When the output information is displayed on the screen, for example, the administrator of the EV management server 100 and the like are notified of the mobility charge information.
Here, the total revenue calculated by the total revenue calculation unit 116 changes according to the mobility temporary charge set by the mobility temporary charge setting unit 111. Therefore, the mobility charge output unit 117 is the revenue calculated by the total revenue calculation unit 116 based on the relationship between the mobility temporary charge set by the mobility temporary charge setting unit 111 and the total revenue calculated by the total revenue calculation unit 116. Identify the mobility charges that maximize the sum of. Then, the mobility charge output unit 117 outputs the specified mobility charge information. Further, the mobility charge output unit 117 may set the value of the specified mobility charge as the actual mobility charge.

Then, each functional unit constituting the EV management server 100 is realized by the cooperation of software and hardware resources. Specifically, for example, when the EV management server 100 is realized with the hardware configuration shown in FIG. 2, various programs stored in the ROM 102, the HDD 104, and the like are read into the RAM 103 and executed by the CPU 101. , Mobility temporary charge setting unit 111, mobility vehicle utilization rate calculation unit 112, mobility revenue calculation unit 113, power supply and demand available number calculation unit 114, power revenue calculation unit 115, total revenue calculation unit 116, mobility charge output unit shown in FIG. A functional unit such as 117 is realized.

Further, in the present embodiment, the mobility revenue calculation unit 113 is used as an example of the first calculation means. The electric power revenue calculation unit 115 is used as an example of the acquisition means, the calculation means, and the second calculation means. As an example of the output means, the mobility charge output unit 117 is used.

<Procedure for outputting mobility charge information>
Next, a processing procedure in which the EV management server 100 outputs mobility charge information will be described. FIG. 4 is a flowchart showing an example of a processing procedure for outputting mobility charge information.
Further, in the following, the processing step may be represented by the symbol “S”.

First, the EV management server 100 acquires the power supply / demand information by transmitting the power supply / demand information from the resource aggregator 400 or the like. Then, the mobility temporary charge setting unit 111 sets a predetermined number of mobility temporary charges (S101). Next, the mobility vehicle utilization rate calculation unit 112 calculates the utilization rate of the EV 300 used by the user for each temporary mobility charge set in S101 (S102).

Next, the mobility revenue calculation unit 113 calculates the mobility revenue when the EV 300 is used at the utilization rate calculated in S102 for each mobility provisional charge set in S101 (S103). Next, the power supply / demand available number calculation unit 114 calculates the number of EV300s that can be used for power supply / demand for each mobility provisional charge set in S101 (S104). Here, the electric power supply / supply available number calculation unit 114 is, for example, an EV 300 that can be used for the supply and demand of electric power, except for the EV 300 that is used at the utilization rate calculated in S102 from all the EV 300s prepared by the mobility service. Calculate the number of units.

Next, the electric power revenue calculation unit 115 calculates the electric power-related revenue obtained when the EV 300 is used for the electric power supply and demand according to the electric power supply and demand information acquired from the resource aggregator 400 and the like for each mobility temporary charge set in S101. .. (S105). Next, the revenue total calculation unit 116 calculates the total of the mobility revenue calculated in S103 and the power-related revenue calculated in S105 for each mobility provisional charge set in S101 (S106).

Next, the mobility charge output unit 117 outputs the mobility charge information when the total of the profits calculated in S106 is maximum (S107). Here, the mobility charge output unit 117 sets the mobility charge that maximizes the total revenue calculated in S106 based on the relationship between the temporary mobility charge set in S101 and the total revenue calculated in S106. Identify. Further, the mobility charge output unit 117 may set the value of the specified mobility charge as the actual mobility charge. Then, this processing flow ends.

<Specific example of processing to output mobility charge information>
Next, a specific example of the process in which the EV management server 100 outputs the mobility charge information will be described with reference to FIGS. 5 and 6.
The steps shown below (that is, the symbol "S") correspond to each step in FIG.

FIG. 5 is a diagram for explaining a specific example of the process of outputting the mobility charge information. In this example, there are 100 EV300s prepared by the mobility service.
Here, when the power supply / demand information is transmitted from the resource aggregator 400 or the like, the mobility temporary charge setting unit 111 sets a predetermined number of temporary mobility charges (S101). In this example, as shown in FIG. 5, the mobility temporary charge setting unit 111 has a mobility temporary charge of 100 to 1000 (yen / unit / h) for every 100 yen (that is, 100 per EV300 unit per hour. ~ 1000 yen usage fee) is set.

Next, the mobility vehicle utilization rate calculation unit 112 calculates the utilization rate of the EV 300 for each temporary mobility charge (S102). In this example, the correlation between the hourly usage fee of the EV300 and the ratio of the EV300 that is expected to be used when renting out at that usage fee is predetermined. The mobility vehicle utilization rate calculation unit 112 calculates the utilization rate of the EV 300 for each temporary mobility charge based on this correlation.
For example, as shown in FIG. 5, when the temporary mobility charge is 100 (yen / unit / h), the utilization rate of the EV300 is calculated to be 92%. In this example, the total number of EV300s prepared by the mobility service is 100, so the number of EV300s expected to be used by users when renting out EV300s at 100 (yen / unit / h) is 92. It becomes a stand.

Next, the mobility revenue calculation unit 113 calculates the mobility revenue for each temporary mobility charge (S103). In this example, the mobility revenue calculation unit 113 calculates the mobility revenue by multiplying the temporary mobility charge by the number of EV300s expected to be used by the user. For example, if the temporary mobility charge is 100 (yen / unit / h), the number of EV300s expected to be used by users is 92, so 100 (yen / unit / h) x 92 = 9200. It becomes (yen / h).

Next, the power supply / demand available number calculation unit 114 calculates the number of EV300s that can be used for power supply / demand for each temporary mobility charge (S104). In this example, the number of EV300s that can be used for power supply and demand, excluding the number of EV300s that are expected to be used in the mobility service from the number of EV300s prepared in the mobility service (100 in this example). Is calculated. For example, if the temporary mobility charge is 100 (yen / unit / h), the number of EV300s expected to be used by users is 92, so the number of EV300s that can be used for power supply and demand is eight. It becomes.

Next, the electric power revenue calculation unit 115 calculates the electric power-related revenue obtained when the EV 300 is used for the electric power supply and demand according to the electric power supply and demand information for each temporary mobility charge (S105).
For example, in the power supply and demand information acquired from the resource aggregator 400 or the like, the information that the profit of 50 (yen / ΔkW / h) can be obtained by providing the adjusting power (that is, the ΔkW value) in a specific time zone is received. Suppose. 50 (yen / ΔkW / h) means that the profit per hour of the adjusting power capable of supplying 1 kW of electric power within a predetermined time is 50 yen. Here, assuming that the discharge output per unit of the EV300 is 10 kW, a profit of 10 (kW / unit) x 50 (yen / ΔkW / h) = 500 (yen / unit / h) (that is, one unit of the EV300 1 unit). You can earn 500 yen per hour). For example, if the temporary mobility charge is 100 (yen / unit / h), the number of EV300s that can be used for power supply and demand is eight, so the power-related revenue is 500 (yen / unit / h) x 8 units. = 4000 (yen / h). The discharge output per EV 300 is determined by the performance of the charging / discharging equipment 201 used for discharging.

Next, the revenue total calculation unit 116 calculates the total of the mobility revenue and the power-related revenue for each mobility provisional charge (S106). For example, when the temporary mobility charge is 100 (yen / unit / h), the mobility revenue is 9200 (yen / h). The electric power-related revenue is 4000 (yen / h). Therefore, the total profit is 13200 (yen / h).

Next, the mobility charge output unit 117 specifies the mobility charge when the total revenue is maximized (S107).
FIG. 6 is a diagram showing an example of the relationship between revenue and temporary mobility charges.
In the example shown in FIG. 6, the vertical axis represents revenue (yen / h) and the horizontal axis represents temporary mobility charges (yen / unit / h). Here, the relationship between the mobility tentative charge and the mobility revenue, the relationship between the mobility tentative charge and the power-related revenue, and the relationship between the mobility tentative charge and the total revenue are shown. Then, when the temporary mobility charge is about 840 (yen / unit / h), the total revenue is maximized. Therefore, the mobility charge output unit 117 outputs the mobility charge information of about 840 (yen / unit / h). By outputting the mobility charge information, the administrator of the EV management server 100 and the like are notified of the mobility charge information. Further, the mobility charge output unit 117 may set the actual value of the mobility charge to about 840 (yen / unit / h).

In addition, when only mobility services are provided without earning electricity-related revenue, as shown in Fig. 6, the mobility fee is set to about 740 yen (yen / unit / h), and the mobility revenue is maximized. Become. On the other hand, when the EV300 not used in the mobility service is used for the supply and demand of electric power to obtain electric power-related revenue as in the present embodiment, the mobility fee is set to about 840 yen (yen / unit / h). Will maximize the sum of mobility revenue and electricity-related revenue.

In this example, in the power supply and demand information acquired from the resource aggregator 400 or the like, information that a profit of 50 (yen / ΔkW / h) can be obtained by providing the adjusting power (ΔkW value) in a specific time zone. I decided to receive it. However, it is conceivable that profits will be obtained by receiving power supply as adjustment power instead of supplying power as adjustment power. For example, when the electric power owned by the business operator becomes surplus, profit may be obtained by receiving the supply of the surplus electric power. In this way, the power supply and demand information may be used to receive information that profits can be obtained by receiving power supply as adjusting power (ΔkW value) at a specific time zone.

<Other examples of power supply and demand information>
Further, in the examples shown in FIGS. 5 and 6, it was decided to receive information on the profit obtained by the adjusting power capable of adjusting the supply and demand of electric power at a specific time zone based on the electric power supply and demand information. However, the revenue information of the power supply and demand information is not limited to the revenue information about such adjustment power.

(Example of profit from supply and demand of a certain amount of electricity)
For example, the EV management server 100 may acquire information on the profit obtained by supplying a certain amount of electric power to the wholesale electricity market at a specific time zone from the electric power supply and demand information acquired from the resource aggregator 400 or the like. The wholesale electricity market is a market in which the supply side that supplies electricity and the demand side such as an electricity retailer trade. Further, the electric power here is generally called a kWh value, and is the value of the actually generated electric power (kWh).

More specifically, for example, in the power supply and demand information acquired from the resource aggregator 400 or the power retailer, the information that the profit of 100 (yen / kWh) can be obtained by supplying power in a specific time zone is provided. Suppose you received it. Here, it is assumed that the discharge output per EV 300 is 6 kW, and the average electricity charge when the EV 300 is charged is 20 (yen / kWh). In this case, the power-related revenue is (100-20) (yen / kWh) x 6 (kW / unit) = 480 (yen / unit / h). That is, the profit obtained per hour for each EV300 is 480 yen.
The average electricity charge when the EV 300 is charged is calculated by averaging, for example, the electricity charges of all the EV 300s prepared by the mobility service in the past. Further, for example, the electricity charges for past charging of the EV 300 may be averaged and calculated for each EV 300.

In addition, in the examples shown in FIGS. 5 and 6, the power-related revenue per EV 300 is set to 500 (yen / unit / h). On the other hand, in this example, the electric power-related revenue per EV 300 is 480 (yen / unit / h). For example, as shown in FIG. 5, when the temporary mobility charge is 100 (yen / unit / h), the number of EV300s that can be used for supplying and receiving electric power is eight. Therefore, the power-related revenue in this case is 480 (yen / unit / h) x 8 units = 3840 (yen / h). Such power-related revenue may be calculated for each provisional mobility fee, and the mobility fee may be specified so as to maximize the total revenue.

Also, in this example, it was decided to earn profits by supplying electricity, but for example, it is also possible to earn profits by suppressing charging when the electricity rate is high and promoting charging when the electricity rate is low. Good. For example, suppose that the electricity supply and demand information receives information that the electricity rate is 50 (yen / kWh) higher than the standard value at a specific time zone. Further, the charging power per EV 300 is set to 6 kW. In this case, the profit from the cost reduction is 50 (yen / kWh) x 6 (kW / unit) = 300 (yen / unit / h). That is, the electric power-related profit obtained per hour for each EV300 is 300 yen.

(Example of profit from reduction of basic electricity charge)
For example, if you have a contract in which the basic charge is determined by the power peak for the past year, you can reduce the basic charge and make a profit by suppressing the power peak.
The power peak indicates the maximum demand power. For example, of the average power consumption every 30 minutes, the largest value in a month is the maximum power demand for that month, and the largest value in the maximum power demand for each month in the past year is the power peak, and the basic charge. Is determined.

For example, when the station 200 is provided in a shopping mall, there is a power load other than the EV 300 (for example, a building of the shopping mall) below the power receiving point. Then, the basic charge of the electric power of the entire electric power load below the receiving point is determined by the electric power peak of the entire electric power load in the past one year. Therefore, by discharging from the EV 300 or suppressing the charging of the EV 300 during the time zone of the power peak of the entire power load, the power peak is suppressed and the basic charge is reduced.

More specifically, for example, the EV management server 100 acquires power supply and demand information from an energy service provider or a resource aggregator 400 that monitors the entire power load of a shopping mall. In this power supply and demand information, it is predicted that the power peak of the shopping center will be set at a specific time, so by suppressing the power peak, the basic charge of the shopping mall will be reduced by 500 yen / kW. It contains information that it will be. Here, the discharge output per hour of each EV300 is set to 6 kW / h. In this case, the power-related revenue is 500 (yen / kW) x 6 (kW / unit / h) = 3000 (yen / unit / h). By discharging from the EV 300 in this way, the power peak of the entire power load of the shopping mall is suppressed, and the basic charge is reduced. As a result, the electric power-related profit obtained per hour for each EV300 is 3000 yen.

In addition, in the examples shown in FIGS. 5 and 6, the power-related revenue per EV 300 is set to 500 (yen / unit / h). On the other hand, in this example, the electric power-related revenue per EV 300 is 3000 (yen / unit / h). For example, as shown in FIG. 5, when the temporary mobility charge is 100 (yen / unit / h), the number of EV300s that can be used for supplying and receiving electric power is eight. Therefore, the power-related revenue in this case is 3000 (yen / unit / h) x 8 units = 24000 (yen / h). Such power-related revenue may be calculated for each provisional mobility fee, and the mobility fee may be specified so as to maximize the total revenue.

If there is a limit to the number of EV300s that can be discharged at the station 200 at the target power receiving point, the profit from the number of EV300s exceeding the limit cannot be obtained.
Further, in this example, an example in which the electric power peak is suppressed by discharging from the EV 300 has been described, but the electric power peak may be suppressed by suppressing the charging of the EV 300, and the benefit of reducing the basic charge may be obtained.

Further, as an example, the station 200 is provided in the shopping mall, but the place where the station 200 is provided may be a place where a power load other than the EV 300 exists below the power receiving point. For example, even if the station 200 is installed in a store with a rental car service building or the station 200 is installed in a mechanical parking lot, there is a power load other than the EV300 below the power receiving point, so that the power is supplied. It is possible to reduce the basic charge by suppressing peaks.

Further, the EV management server 100 may acquire a plurality of power supply and demand information. For example, the EV management server 100 can be obtained by supplying electric power supply and demand information from a resource aggregator 400 or the like to information on profits obtained by providing adjustment power to a power transmission and distribution operator 500, or by supplying electric power to the wholesale electricity market. Get revenue information. In this case, for example, the EV300 that can be used for the supply and demand of electric power is allocated to either the EV300 that provides adjustment power to the power transmission and distribution operator 500 or the EV300 that supplies electric power to the wholesale electricity market, and the respective profits are totaled. To calculate electricity-related revenue. Here, the EV 300 may be allocated so as to maximize the power-related profit.

<Modification example>
Next, a modified example of the present embodiment will be described.

(Other examples of mobility charges specified by the mobility charge output unit 117)
In the above example, the mobility charge output unit 117 specifies the mobility charge when the total revenue calculated by the total revenue calculation unit 116 is maximum. However, the mobility charge specified by the mobility charge output unit 117 is not limited to the one that maximizes the total revenue calculated by the total revenue calculation unit 116.

For example, the mobility charge output unit 117 may specify the mobility charge when the total revenue calculated by the total revenue calculation unit 116 is equal to or greater than a predetermined target value. In the example shown in FIG. 6, when the target value of the total revenue is set to 60,000 yen, the mobility charge in which the total revenue exceeds the target value is, for example, a charge in the range of about 720 to 920 (yen / vehicle / h). Is identified.

As described above, in the present embodiment, the mobility charge output unit 117 specifies the mobility charge when the total revenue calculated by the total revenue calculation unit 116 satisfies a predetermined condition. The predetermined conditions here are, for example, a condition that the total profit is maximized and a condition that the total profit is equal to or more than a predetermined target value.

In addition, the mobility charge output unit 117 may specify the mobility charge in consideration of other conditions as well as a predetermined condition for the total revenue. For example, as another condition, an upper limit may be set on the mobility charge so that the mobility charge does not become too high, or a lower limit may be set on the mobility charge so that the mobility charge does not become too low.

(Another example of calculating the number of EV300s that can be used for power supply and demand)
In the above example, the power supply / demand available number calculation unit 114 calculates the number of EV300s that can be used for power supply / demand, excluding the EV300 used in the mobility service, from all the EV300s prepared in the mobility service. That is, all EV300s that are not used in the mobility service are EV300s that can be used for the supply and demand of electric power. However, the present embodiment is not limited to such a configuration.

For example, the power supply / demand available unit calculation unit 114 satisfies a specific condition for obtaining power-related profits among all EV300s prepared in the mobility service, excluding the EV300 used in the mobility service. Let the EV300 be an EV300 that can be used for the supply and demand of electric power.

Specifically, for example, the power supply / demand available unit calculation unit 114 is used to obtain power-related revenue from all the EV300s prepared in the mobility service, excluding the EV300 used in the mobility service. At the designated time point, the EV300 in which the remaining amount of charging power of the rechargeable battery 301 is equal to or higher than a predetermined threshold value is defined as the EV300 that can be used for the supply and demand of power.
For example, in the power supply and demand information, when a power output of 6 kW is required for 30 minutes per EV 300, it cannot be used for power supply and demand unless the remaining charge power amount is at least 3 kWh or more. In this case, the power supply / demand available unit calculation unit 114 can use the EV300 whose remaining chargeable power of the rechargeable battery 301 is 3 kWh or more at the time specified for obtaining the power-related profit, and can use the EV300 for the power supply / demand. And.

The remaining amount of charging power of the rechargeable battery 301 may be calculated for the entire EV 300 or for each EV 300.
For example, the electric power supply / supply available number calculation unit 114 records the transition of the remaining amount of the charged electric energy in the entire EV 300, and calculates the statistics for each month, each day of the week, and each time zone. Based on this statistic, the number of EV300s for which the remaining amount of charging power is predicted to be equal to or higher than a predetermined threshold value is calculated.
Further, for example, the power supply / demand available number calculation unit 114 predicts the remaining amount of the charged electric energy of the EV 300 based on the schedule for renting the EV 300 and the schedule for charging the EV 300 for each EV 300. Then, for each EV 300, it is determined whether or not the remaining amount of charging power exceeds a predetermined threshold value.

Further, for example, the power supply / demand available unit calculation unit 114 is designated to obtain power-related revenue from all EV300s prepared in the mobility service, excluding the EV300 used in the mobility service. At this point, the EV 300 that can reach the station 200 may be the EV 300 that can be used for the supply and demand of electric power.
Specifically, for example, in the power supply and demand information, when it is required to supply power at 0:00 on March 1, 2019, the station 200 must be reached by 0:00 on March 1, 2019. For example, it cannot be used for the supply and demand of electricity. In this case, the power supply / demand available number calculation unit 114 sets the EV300 that can reach any station 200 by 0:00 on March 1, 2019 as the EV300 that can be used for power supply / demand.

Whether or not the station 200 can be reached may be calculated for the entire EV 300 or for each EV 300.
For example, the power supply / demand available unit calculation unit 114 records the position where each EV 300 exists in the entire EV 300, and calculates the statistics for each month, each day of the week, and each time zone. Based on this statistic, the number of EV300s predicted to arrive at the station 200 by the designated time point is calculated.
Further, for example, the electric power supply / supply available number calculation unit 114 determines whether or not the station 200 can arrive at each EV 300 based on the rental schedule of the EV 300. For example, it is determined that the EV 300, which is reserved for rent in the vicinity of the designated time point for obtaining power-related revenue, cannot reach the station 200 by the designated time point.
Here, when the power peak is suppressed to reduce the basic power charge, the EV 300 that can reach the station 200 at the target power receiving point is treated as the EV 300 that can be used for the supply and demand of power.

(Other examples when calculating the utilization rate of EV300)
Further, the mobility vehicle utilization rate calculation unit 112 may use information other than the mobility provisional charge together with the mobility provisional charge when calculating the utilization rate of the EV300 used by the user. Information other than the temporary mobility charge includes, for example, information such as the area where the EV300 is rented, the day of the week, the time of day, and the weather.

For example, the relationship between the temporary mobility charge and the utilization rate is predetermined for areas such as urban areas and rural areas. Specifically, for example, by comparing urban areas and rural areas, it is stipulated that in urban areas, the utilization rate tends to be difficult to decrease even if the temporary mobility charge is increased. The mobility vehicle utilization rate calculation unit 112 calculates the utilization rate of the EV 300 for each area based on the relationship between the temporary mobility charge and the utilization rate. Further, for example, the mobility vehicle utilization rate calculation unit 112 may record the usage fee when the EV 300 is used for each area, and calculate the utilization rate of the EV 300 for each area based on the recorded data. Good.

Further, for example, the relationship between the temporary mobility charge and the usage rate is predetermined for the date and time such as the day of the week and the time zone. Specifically, for example, comparing weekdays and weekends, it is defined that if the mobility provisional charges are the same, the utilization rate tends to be higher on weekdays than on weekends. Further, for example, by comparing midnight and daytime, it is determined that the utilization rate tends to be difficult to decrease at midnight even if the temporary mobility charge is increased. The mobility vehicle utilization rate calculation unit 112 calculates the utilization rate of the EV 300 according to the day of the week and the time zone based on the relationship between the temporary mobility charge and the utilization rate. Further, for example, the mobility vehicle utilization rate calculation unit 112 records the transition of the utilization rate of the EV300 for each day of the week and each time zone, and calculates the utilization rate of the EV300 according to the day of the week and the time zone based on the recorded data. You may.

Further, for example, the relationship between the temporary mobility charge and the utilization rate is predetermined for the weather such as rain or sunny weather. Specifically, for example, it is defined that the utilization rate tends to be difficult to decrease even if the temporary mobility charge is increased in the case of rain by comparing the case of rain and the case of sunny weather. The mobility vehicle utilization rate calculation unit 112 calculates the utilization rate of the EV 300 based on the relationship between the temporary mobility charge and the utilization rate. Further, for example, the mobility vehicle utilization rate calculation unit 112 may record the transition of the utilization rate of the EV 300 for each weather, and calculate the utilization rate of the EV 300 due to the weather based on the recorded data.

The mobility vehicle utilization rate calculation unit 112 may calculate the utilization rate by using a plurality of information such as the area where the EV300 is rented, the day of the week, the time zone, and the weather.
Further, the mobility vehicle utilization rate calculation unit 112 does not use the information on the temporary mobility charge, but based on the information such as the area where the EV300 is rented, the day of the week, the time zone, and the weather, the utilization rate of the EV300, in other words, the mobility service. Demand may be calculated. That is, the mobility vehicle utilization rate calculation unit 112 does not change the utilization rate for each temporary mobility charge, but changes the utilization rate of the EV300 according to information such as the area where the EV300 is rented, the day of the week, the time zone, and the weather. Good.

(Other examples of revenue units)
In the above example, the usage fee (yen / vehicle / h) per hour for each EV300 is used as the unit of mobility revenue, but the usage fee is not limited to the one converted into such time. .. For example, as the usage fee converted into the distance, the usage fee (yen / vehicle / km) per 1 km of the EV300 may be used. Further, the usage fee converted into time and the usage fee converted into distance may be combined. In addition, since the usage fee converted into time is used for the electric power-related revenue, when the mobility revenue and the electric power-related revenue are totaled, the usage fee converted into distance is converted into the usage fee converted into time.

(Other variants)
In the above example, the mobility charge output unit 117 specifies the mobility charge when the total revenue calculated by the total revenue calculation unit 116 satisfies a predetermined condition. However, in this embodiment, it is not necessary to calculate the total revenue.
For example, the mobility charge output unit 117 may specify the mobility charge based on the mobility revenue and the power-related revenue. For example, the mobility charge output unit 117 may output information on the mobility charge when both the mobility revenue and the power-related revenue are equal to or higher than the threshold value, or may set the mobility charge. Further, for example, the mobility charge output unit 117 may output information on the mobility charge when both the mobility revenue and the power-related revenue are within a certain range, or may set the mobility charge.

Further, the mobility charge output unit 117 may specify the mobility charge not by the mobility income but by the electric power-related income. That is, in the present embodiment, in order to change the mobility charge according to the electric power-related revenue, the mobility charge may be specified in consideration of the electric power-related revenue.
For example, the mobility charge output unit 117 can use the EV 300 if the power-related revenue obtained when a certain number of EV 300s are used for the power supply and demand is equal to or higher than the threshold value when the power supply and demand is requested by the power supply and demand information. In order to refrain from using the service, you may output a notification to raise the mobility fee to a certain amount or more. In addition, if the power-related revenue obtained when a certain number of EV300s are used for power supply and demand is less than the threshold value, a notification is output to the effect that the mobility fee will be reduced to less than a certain amount in order to promote the use of the EV300. You may.
Further, for example, the mobility charge output unit 117 may use a certain amount or more to refrain from using the EV300 if the electricity charge for charging the EV300 is less than the threshold value when the power supply / supply request is made based on the power supply / demand information. If the electricity charge for charging the EV300 is above the threshold, a notification will be output to the effect that the electricity charge will be reduced to less than a certain amount in order to promote the use of the EV300. You may do it.

Even in such a modification, the profit obtained from the mobility service and the power-related profit may be used instead of the mobility profit and the power-related profit.

Further, in the present embodiment, the station 200 is not limited to the configuration in which the charging / discharging equipment 201 corresponding to both charging and discharging is provided. The station 200 may be provided with equipment capable of charging or discharging at least one of them. Further, there may be a station 200 that is provided with a charger but not provided with a discharger, or there may be a station 200 that is provided with a charger but is not provided with a charger.

Further, in the present embodiment, a part of the functions of the EV management server 100 may be realized by another device. For example, the mobility temporary charge setting unit 111, the mobility vehicle utilization rate calculation unit 112, the mobility revenue calculation unit 113, the power supply / demand available number calculation unit 114, the power revenue calculation unit 115, the total revenue calculation unit 116, the mobility charge output unit 117, etc. Some processing may be executed by another device.
