Abstract

A power management system includes a vehicle and a charging or discharging lane. The charging or discharging lane configured to execute at least one of charging or discharging of the vehicle in a non-contact manner. The vehicle is configured to acquire contract contents including a charging or discharging amount and a charging or discharging period. The vehicle is configured to execute the contract contents in a charging or discharging lane that is different from electric vehicle supply equipment set in the contract contents and is reachable before the charging or discharging period when the vehicle is predicted to, before a start of the charging or discharging period, be unable to execute the contract contents in the set electric vehicle supply equipment.

First claim

What is claimed is:

1. A power management system comprising:
a vehicle; and
a charging or discharging lane configured to execute at least one of charging or discharging of the vehicle in a non-contact manner,
wherein the vehicle is configured to:
acquire contract contents including a charging or discharging amount that defines at least one of a charging amount or a discharging amount, and a charging or discharging period that defines at least one of a charging period or a discharging period; and
execute the contract contents in a charging or discharging lane that is different from electric vehicle supply equipment set in the contract contents and is reachable before the charging or discharging period when the vehicle is predicted to, before a start of the charging or discharging period, be unable to execute the contract contents in the set electric vehicle supply equipment.

2. The power management system according to claim 1 , wherein the power management system is configured to, when the vehicle is predicted to, before the start of the charging or discharging period, be unable to execute the contract contents in the set electric vehicle supply equipment, guide a user of the vehicle to travel in the charging or discharging lane.

3. The power management system according to claim 1 , further comprising a server configured to communicate with the vehicle,
wherein the server is configured to, when the contract contents are executed in the charging or discharging lane which is reachable before the charging or discharging period, receive execution completion information indicating that the contract contents has been executed.

4. The power management system according to claim 3 , wherein the vehicle is configured to send the execution completion information to the server.

5. The power management system according to claim 4 , wherein the server is configured to, when the vehicle is predicted to, before the start of the charging or discharging period, be unable to execute the contract contents in the set electric vehicle supply equipment and be unable to reach the charging or discharging lane in which the contract contents are executable before the charging or discharging period, send a request signal for requesting a substitute vehicle chargeable or dischargeable in the charging or discharging lane to execute the charging or the discharging based on the contract contents of the vehicle.

6. The power management system according to claim 5 , wherein the substitute vehicle is configured to, upon receiving the request signal from the server, send, to the server, a response signal indicating whether to execute the charging or the discharging based on the contract contents of the vehicle.

7. The power management system according to claim 6 , wherein:
the server is configured to, upon receiving the response signal indicating that the charging or the discharging is executed based on the contract contents of the vehicle, send, to the vehicle, vehicle information indicating the substitute vehicle that has sent the response signal; and
the vehicle is configured to, upon receiving the vehicle information, give a user of the vehicle a notification indicating that the substitute vehicle executes the charging or the discharging based on the contract contents of the vehicle.

8. The power management system according to claim 6 , wherein the server is configured to, upon receiving the response signal indicating that the charging or the discharging is executed based on the contract contents of the vehicle, send, to the substitute vehicle, a request signal for requesting that the charging or the discharging be executed based on the contract contents of the vehicle.

9. The power management system according to claim 8 , wherein the substitute vehicle is configured to, upon receiving the request signal from the server, guide a user of the substitute vehicle to travel in the charging or discharging lane in which the charging or the discharging requested in the request signal is executed.

10. The power management system according to claim 1 , wherein the contract contents define the charging or discharging amount and the charging or discharging period, but do not define electric vehicle supply equipment in which the charging or the discharging is executed.

11. A vehicle comprising:
a power device in which charging or discharging is executed by a charging or discharging lane configured to execute at least one of the charging or the discharging of the vehicle in a non-contact manner; and
a processor configured to:
acquire contract contents including a charging or discharging amount that defines at least one of a charging amount or a discharging amount, and a charging or discharging period that defines at least one of a charging period or a discharging period; and
execute the contract contents in a charging or discharging lane that is different from electric vehicle supply equipment set in the contract contents and is reachable before the charging or discharging period when the vehicle is predicted to, before a start of the charging or discharging period, be unable to execute the contract contents in the set electric vehicle supply equipment.

12. A server comprising:
a communication interface configured to communicate with a vehicle; and
a processor, wherein:
the vehicle includes a power device in which charging or discharging is executed by a charging or discharging lane configured to execute at least one of the charging or the discharging of the vehicle in a non-contact manner, and is configured to
acquire contract contents including a charging or discharging amount that defines at least one of a charging amount or a discharging amount, and a charging or discharging period that defines at least one of a charging period or a discharging period, and
execute the contract contents in a charging or discharging lane that is different from electric vehicle supply equipment set in the contract contents and is reachable before the charging or discharging period when the vehicle is predicted to, before a start of the charging or discharging period, be unable to execute the contract contents in the set electric vehicle supply equipment; and

the processor is configured to, when the vehicle executes the contract contents in the charging or discharging lane, receive execution completion information indicating that the contract contents have been executed.
