Abstract

A server configured to communicate with a first vehicle and a second vehicle, each of the first vehicle and the second vehicle including a power storage device configured to be charged by wirelessly receiving electric power from a power transmission device arranged on a road during traveling, the server includes: a storage device that stores information on a power shortage area; and a processor configured to: acquire a destination of the first vehicle and a destination of the second vehicle; and limit a charging operation for the second vehicle when the destination of the first vehicle is included in the power shortage area stored in the storage device, the destination of the second vehicle is not included in the power shortage area, and the first vehicle is charged on the road.

First claim

What is claimed is:

1 . A server configured to communicate with a first vehicle and a second vehicle, each of the first vehicle and the second vehicle including a power storage device configured to be charged by wirelessly receiving electric power from a power transmission device arranged on a road during traveling,
the server comprising:
a storage device that stores information on a power shortage area and stores priority levels for areas included in the power shortage area; and
a processor configured to:
acquire a destination of the first vehicle and a destination of the second vehicle;
limit a charging operation for the second vehicle when the destination of the first vehicle is included in the power shortage area stored in the storage device, the destination of the second vehicle is not included in the power shortage area, and the first vehicle is charged on the road; and
when a plurality of vehicles is performing the charging operation on the road and the number of the vehicles exceeds a predetermined number:
acquire the priority levels for the destination of each of the vehicles, and
limit the charging operation for a vehicle of which the priority level for the destination is low as compared with the charging operation for a vehicle of which the priority level for the destination is high,

the vehicles having destinations set to the power shortage area and being configured to be charged by the electric power from the power transmission device.

2 . The server according to claim 1 , wherein:
the road includes a first lane where the power transmission device is arranged, and a second lane where the power transmission device is not arranged; and the processor is configured to limit the charging operation for the second vehicle by notifying the second vehicle of information for preventing entry into the first lane.

3 . The server according to claim 2 , wherein the processor is configured to, when the second vehicle is traveling in the first lane, limit the charging operation for the second vehicle by notifying the second vehicle of information for requesting the second vehicle to leave the first lane.

4 . The server according to claim 1 , wherein:
the road includes a first lane where the power transmission device is arranged, and a second lane where the power transmission device is not arranged; and the processor is configured to, when the second vehicle is traveling in the first lane, limit the charging operation for the second vehicle by notifying the second vehicle of information for requesting the second vehicle to leave the first lane.

5 . The server according to claim 1 , wherein the processor is configured to, when the second vehicle is performing the charging operation on the road, limit the charging operation for the second vehicle by transmitting a command to the power transmission device to reduce the electric power to be supplied to the second vehicle.

6 . The server according to claim 5 , wherein the processor is configured to, when the second vehicle is performing the charging operation on the road, limit the charging operation for the second vehicle by transmitting a command to the power transmission device to stop power supply to the second vehicle.

7 . The server according to claim 1 , wherein the processor is configured to, when the plurality of vehicles is performing the charging operation on the road and total electric power to be supplied to the vehicles exceeds suppliable electric power of the power transmission device:
acquire state of charge of each of the vehicles; and limit the charging operation for the vehicle of which the state of charge is high as compared with the charging operation for the vehicle of which the state of charge is low, the vehicles having destinations set to the power shortage area and being configured to wirelessly receive the electric power from the power transmission device.

8 . The server according to claim 1 , wherein:
the storage device stores a priority level for each area included in the power shortage area; and the processor is configured to, when the plurality of vehicles is performing the charging operation on the road and total electric power to be supplied to the vehicles exceeds suppliable electric power of the power transmission device:
acquire the priority level for the destination of each of the vehicles; and
limit the charging operation for the vehicle of which the priority level for the destination is low as compared with the charging operation for the vehicle of which the priority level for the destination is high,
the vehicles having destinations set to the power shortage area and being configured to be charged by the electric power from the power transmission device.

9 . The server according to claim 1 , wherein the processor is configured to, when the plurality of vehicles is performing the charging operation on the road and the number of the vehicles exceeds the predetermined number:
acquire state of charge of each of the vehicles; and limit the charging operation for a vehicle of which the state of charge is high as compared with the charging operation for a vehicle of which the state of charge is low, the vehicles having destinations set to the power shortage area and being configured to be charged by the electric power from the power transmission device.

10 . A power supply system comprising:
a power transmission device arranged on a road; a first vehicle and a second vehicle; and a server configured to communicate with the first vehicle and the second vehicle, wherein: each of the first vehicle and the second vehicle includes a power storage device configured to be charged with electric power wirelessly received from the power transmission device during traveling; the server includes:
a processor; and
a storage device that stores information on a power shortage area and stores priority levels for areas included in the power shortage area; and
the processor is configured to:
acquire a destination of the first vehicle and a destination of the second vehicle;
limit a charging operation for the second vehicle when the destination of the first vehicle is included in the power shortage area stored in the storage device, the destination of the second vehicle is not included in the power shortage area, and the first vehicle is charged on the road; and
when a plurality of vehicles is performing the charging operation on the road and the number of the vehicles exceeds a predetermined number:
acquire the priority levels for the destination of each of the vehicles, and
limit the charging operation for a vehicle of which the priority level for the destination is low as compared with the charging operation for a vehicle of which the priority level for the destination is high,

the vehicles having destinations set to the power shortage area and being configured to be charged by the electric power from the power transmission device.

11 . A vehicle configured to communicate with a server and wirelessly receive electric power from a power transmission device arranged on a road during traveling, the vehicle comprising:
a power reception device configured to receive the electric power from the power transmission device; a power storage device configured to be charged with the electric power received by the power reception device; and a processor, wherein: the server stores information on a power shortage area and stores priority levels for areas included in the power shortage area; and the processor is configured to, when a destination of the vehicle is included in the power shortage area acquired from the server and the power storage device is charged with t
