[0008] [Figure 1] 1 is a diagram showing an example of the configuration of a parking lot power generation system according to a first embodiment. [Diagram 2] FIG. 2 is a diagram showing an example of the operation of the parking lot power generation system according to the first embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] (First embodiment) First, the configuration of a parking lot power generation system 1 according to the first embodiment will be described with reference to Fig. 1. Fig. 1 is a diagram showing an example of the configuration of the parking lot power generation system 1 according to the first embodiment.

[0010] The parking lot power generation system 1 includes a plurality of cars 10 capable of generating electricity, a parking lot where the plurality of cars 10 can be parked, a power supply device 20 that accepts the supply of electricity generated by the plurality of cars 10, and an electricity consumer 30 that uses the electricity generated by the plurality of cars 10.

[0011] The car 10 is a vehicle equipped with a power generation device (for example, a generator for FC power generation). In this embodiment, the owner of the car 10 is an employee of the business. The owner of the car 10 may be a person who is not an employee of the business. The car 10 is a passenger vehicle such as an electric vehicle. The car 10 is not limited to a passenger vehicle, and may be a commercial vehicle such as a taxi or a delivery company, or may be a large truck or a trailer. The car 10 may also be a moped, motorcycle, or electric kick starter. In other words, the car 10 may be any mobile body that has a power generation function and a power storage function.

[0012] The parking lot is a power generation location for the multiple cars 10. In this embodiment, the parking lot is a parking lot for the business office to which the employees belong. The parking lot may be a supermarket parking lot. The reason why the power generation location is preferably a parking lot is that there is a space where the multiple cars 10 can be parked, and there are potential customers who will use a large amount of power near the parking lot. Since power transmission generates losses, it is preferable that the parking lot where the multiple cars 10 can be parked is as close as possible to the power usage destination 30. However, if the power transmission loss is ignored, the power may be sold to a power company. The power generation location for the multiple cars 10 is not limited to a parking lot. For example, the power generation location may be a remote area where the power transmission network is not sufficiently developed (for example, a roadside station or a tourist spot in a remote area). It takes a lot of effort to secure power by laying a power transmission line far away from a large-scale power plant such as a thermal power plant. However, in the parking lot power generation system 1, as long as the cars 10 can drive themselves, the multiple cars 10 can gather at the site to generate power and use the electricity.

[0013] The power supply device 20 includes an identification unit 21, a power supply acceptance unit 22, a power measurement unit 23, a power adjustment unit 24, a price payment unit 25, and a power measurement unit 26 for power sale. The identification unit 21 identifies the owner of the car 10 parked in the parking lot. The power supply receiving unit 22 can be connected to the vehicle 10 via a connector or the like, and receives power supply from the vehicle 10 whose owner has been identified. The power supply receiving unit 22 is also connected to a power adjustment unit 24, and supplies the received power to the power supply receiving unit 22. The power measuring unit 23 measures the amount of power (hereinafter, referred to as the amount of power supply) received from the vehicle 10. For example, the power measuring unit 23 is a device such as an integrating wattmeter. A plurality of units each including an identification unit 21, a power supply acceptance unit 22, and a power measurement unit 23 are installed in the parking lot.

[0014] The power adjustment unit 24 is connected to the multiple power supply receiving units 22, collects power supplied from the multiple vehicles 10, and adjusts the voltage and current of the collected power. The power adjustment unit 24 is, for example, a device such as a power conditioner. The power adjustment unit 24 is also connected to a general power transmission network that is connected to the power consumer 30, and transmits the power whose voltage and current have been adjusted to the general power transmission network.

[0015] The power-for-sale power measuring unit 26 measures the amount of supplied power whose voltage and current have been adjusted by the power adjusting unit 24. For example, the power-for-sale power measuring unit 26 is a device such as an integrating wattmeter.

[0016] The consideration payment unit 25 pays a consideration (e.g., money) to the owner of the vehicle 10 according to the amount of power supply of the vehicle 10 measured by the power measurement unit 23. The consideration payment unit 25 is configured to be installed in the power supply receiving unit 22, and pays a consideration to the owner of the vehicle 10 according to the amount of power supply at the time of power supply. The consideration payment unit 25 may be configured as a server, and may identify the owner of the vehicle 10 to which power has been supplied, and pay a consideration to the owner of the vehicle 10 according to the amount of power supply.

[0017] In this embodiment, the power consumer 30 is a business establishment to which an employee belongs. Note that the power consumer 30 may also be an ordinary home or the like.

[0018] Next, the operation of the parking lot power generation system 1 according to the first embodiment will be described with reference to Fig. 2. Fig. 2 is a flowchart showing the operation of the parking lot power generation system 1 according to the first embodiment. In the following example, the owner of the car 10 is an "employee." The parking lot is a "parking lot of the business establishment to which the employee belongs." The power consumer 30 is the "business establishment to which the employee belongs."

[0019] <Electricity flow> As shown in FIG. 2, in step S101, an employee comes to work in his / her own car 10 and parks the car 10 in a parking lot of the business establishment 30 to which the employee belongs. Then, the employee connects the car 10 to the power supply reception unit 22 of the power supply device 20. The employee inserts his / her employee ID card into the identification unit 21 of the power supply device 20. The employee may input an ID and a password into the identification unit 21. In step S102, the identification unit 21 of the power supply device 20 identifies the employee based on the input employee ID. When an ID and a password are input, the identification unit 21 may identify the employee based on the input ID and password.

[0020] Next, the vehicle 10 of the identified employee generates power and supplies the generated power (400V (AC)) to the power supply device 20. Specifically, the vehicle rectifies and boosts the generated power using an on-board inverter, and supplies the rectified and boosted power (400V (AC)) to the power supply device 20. In step S103, the power supply receiving unit 22 of the power supply device 20 receives the supply of power (400 V (AC)) generated from the vehicle 10. At this time, the power measuring unit 23 of the power supply device 20 measures the amount of supplied power.

[0021] Next, in step S104, the power adjustment unit 24 of the power supply device 20 collects the power received from the multiple vehicles 10 through the multiple power supply receiving units 22, and boosts the collected power of 400 V (AC) to 6600 V (AC). At this time, the power selling power measurement unit 26 measures the amount of power supply adjusted by the power adjustment unit 24.

[0022] Next, in step S105, the power adjustment unit 24 of the power supply device 20 transmits power to a general power grid connected to the business establishment 30. Next, in step S106, the on-board wattmeter of the business establishment 30 measures the amount of power transmitted from the power supply device 20 via the general power grid. In step S107, the business establishment 30 may purchase the power that is short of the power transmitted from the power supply device 20 from a power company or the like.

[0023] Next, in step S107, the column transformer of the business establishment 30 acquires the power measured by the on-board power meter and the purchased power, and reduces the acquired 6600V (AC) power to 100V power for general household appliances or 200V power for air conditioners. Finally, in step S108, the business establishment 30 uses the stepped-down power.

[0024] <Money flow> In step S201, when the consideration payment unit 25 of the power supply device 20 receives power supply from the vehicle 10, the consideration such as money is transferred from the business establishment 30 to the employee's salary account in accordance with the amount of power supply. Next, in step S202, the employee who owns the car 10 receives the payment.

[0025] In the above example, the voltage at the time of power generation of the vehicle 10 is not limited to 400V (AC). In addition, in step S104, the voltage converted by the power adjustment unit 24 of the power supply device 20 is not limited to 6600V (AC). In step S107, the voltage converted by the pole transformer of the business establishment 30 is not limited to 100V or 200V.

[0026] The parking lot power generation system 1 according to the first embodiment collects power supplied from a plurality of cars 10, adjusts the voltage and current of the collected power, and sells the power. The parking lot power generation system 1 also measures the amount of power supplied from the cars 10, and pays the owner of the car 10 a compensation in accordance with the measured amount of power supplied. Therefore, the parking lot power generation system 1 can generate added value even for parked cars, which was previously difficult to do because cars are parked most of the 24 hours a day.

[0027] Furthermore, when the parking lot power generation system 1 is used by an employee of a business establishment, the system can generate new profits from buying and selling the car 10 while the employee is parked during work hours. In other words, the parking lot power generation system 1 can promote the buying and selling of electricity as a welfare measure for employees belonging to the business establishment by carrying out the buying and selling of electricity in the parking lot of the business establishment. Furthermore, the parking lot power generation system 1 allows the business establishment to supplement its daytime peak power demand with the electricity generated by the car 10 of the employee who comes to work.

[0028] Each component of the parking lot power generation system 1 in the above-described embodiment is configured by hardware or software, or both, and may be configured by one piece of hardware or software, or may be configured by multiple pieces of hardware or software.
