Abstract

A server device includes a processor and a memory storing a program executed by the processor. The processor is configured to accept a tender for a transaction of electricity transfer in a parking lot, contract the transaction of electricity transfer corresponding to the tender, and perform charge control for charging at least one vehicle out of a plurality of vehicles located in the parking lot, the at least one vehicle having placed the tender.

First claim

What is claimed is:

1. A server device configured to conduct a transaction of electricity transfer using a charger in a parking lot, the server device comprising:
a processor; and
a memory storing a program executed by the processor,
wherein the processor is configured to:
accept a tender for the transaction of electricity transfer in the parking lot;
contract the transaction of electricity transfer corresponding to the tender; and
perform charge control for charging at least one vehicle for which the tender has been placed, out of a plurality of vehicles located in the parking lot, wherein
during a first time period, the transaction of electricity transfer is agreed upon for a first vehicle among the plurality of vehicles, wherein the first vehicle is in a first parking space of the parking lot, and
during a second time period following the first time period, the transaction of electricity transfer is agreed upon for the first vehicle in a second parking space of the parking lot, and a second vehicle among the plurality of vehicles that has agreed to the transaction of electricity transfer in the first parking space during the second time period exchanges parking spaces with the first vehicle such that the electricity transfer to the first vehicle will take place during the second time period in the first parking space and the electricity transfer to the second vehicle will take place during the second time period in the second parking space.

2. The server device according to claim 1 , wherein:
the charger includes a charging arm having a charging connector configured to be used for charging; and
the processor is configured to connect the charging connector to a charging port of the at least one vehicle by operating the charging arm according to the charge control.

3. The server device according to claim 1 , wherein:
the parking lot includes a transport device configured to transport each of the vehicles toward the charger; and
the processor is configured to transport the at least one vehicle toward the charger by operating the transport device according to the charge control.

4. The server device according to claim 1 , wherein the at least one vehicle is configured to operate according to the charge control to move toward the charger.

5. The server device according to claim 1 , wherein the processor is configured to transmit a contract result upon contracting the transaction of electricity transfer to a user terminal owned by a user of the at least one vehicle.

6. The server device according to claim 1 , wherein when the number of the vehicles wishing the transactions of electricity transfer is greater than the number of the chargers, the processor is configured to accept the tender from the at least one vehicle out of the vehicles.

7. The server device according to claim 1 , wherein the processor is configured to accept a reservation for the parking lot along with the tender.

8. The server device according to claim 1 , wherein when the tenders are accepted from the vehicles, the processor is configured to contract the transaction of electricity transfer corresponding to the tender by giving an incentive based on at least one of an amount of electricity and a charging time in the transaction of electricity transfer.

9. An electricity transaction system configured to conduct a transaction of electricity transfer using a charger in a parking lot, the electricity transaction system comprising:
the charger; and
a server device,
wherein the server device is configured to:
accept a tender for the transaction of electricity transfer in the parking lot;
contract the transaction of electricity transfer corresponding to the tender; and
perform charge control for charging at least one vehicle out of a plurality of vehicles located in the parking lot, the at least one vehicle having placed the tender, wherein
during a first time period, the transaction of electricity transfer is agreed upon for a first vehicle among the plurality of vehicles, wherein the first vehicle is in a first parking space of the parking lot, and
during a second time period following the first time period, the transaction of electricity transfer is agreed upon for the first vehicle in a second parking space of the parking lot, and a second vehicle among the plurality of vehicles that has agreed to the transaction of electricity transfer in the first parking space during the second time period exchanges parking spaces with the first vehicle such that the electricity transfer to the first vehicle will take place during the second time period in the first parking space and the electricity transfer to the second vehicle will take place during the second time period in the second parking space.
