Abstract

A server that receives an instruction related to timer charging in a vehicle from a user includes a communication device and a controller. The instruction from the user includes first data needed for determining a time schedule and second data indicating which one of alternating current charging and direct current charging is performed. The controller is configured to control the communication device to transmit the first data to the vehicle when the second data indicates the alternating current charging, and control the communication device to transmit the first data to a direct current electric power supply facility when the second data indicates the direct current charging.

Claims

1. A server configured to receive an instruction related to timer charging in a vehicle from a user, the server comprising:

a communication device configured to communicate with the vehicle and a direct current electric power supply facility as an electric power supply; and

a controller configured to control the communication device, wherein;

the timer charging is external charging that is executed in accordance with a time schedule;

the external charging is charging of a vehicle-mounted electric power storage device using electric power supplied from an electric power supply outside the vehicle;

the vehicle is configured to enable both of alternating current charging that is the external charging using alternating current electric power supplied from an alternating current electric power supply facility as the electric power supply, and direct current charging that is the external charging using direct current electric power supplied from the direct current electric power supply facility;

the instruction from the user includes first data needed for determining the time schedule and second data indicating which one of the alternating current charging and the direct current charging is performed; and

the controller is configured to

control the communication device to transmit the first data to the vehicle when the second data indicates the alternating current charging, and

control the communication device to transmit the first data to the direct current electric power supply facility when the second data indicates the direct current charging.

2. The server according to claim 1, wherein:

the communication device is configured to communicate with a communication terminal into which the user inputs the instruction; and

the server is configured to receive both of the first data and the second data from the communication terminal.

3. The server according to claim 1, wherein:

the communication device is configured to communicate with a communication terminal into which the user inputs the instruction; and

the server is configured to receive the first data from the communication terminal, and receive the second data from the vehicle.

4. The server according to claim 1, further comprising a storage device in which a vehicle identification and a direct current electric power supply facility identification are registered in association with each other.

5. The server according to claim 4, wherein:

the first data includes the vehicle identification and an expected departure time; and

the controller is configured to transmit the expected departure time to the direct current electric power supply facility registered in association with the vehicle identification when the second data indicates the direct current charging.

6. A charging system comprising:

a vehicle;

a direct current electric power supply facility configured to supply direct current electric power to the vehicle; and

a server configured to receive an instruction related to timer charging in the vehicle from a user, the server including a communication device configured to communicate with the vehicle and the direct current electric power supply facility, and a controller configured to control the communication device, wherein;

the timer charging is external charging that is executed in accordance with a time schedule;

the external charging is charging of a vehicle-mounted electric power storage device using electric power supplied from an electric power supply outside the vehicle;

the vehicle is configured to enable both of alternating current charging that is the external charging using alternating current electric power supplied from an alternating current electric power supply facility as the electric power supply, and direct current charging that is the external charging using direct current electric power supplied from the direct current electric power supply facility;

the instruction from the user includes first data needed for determining the time schedule and second data indicating which one of the alternating current charging and the direct current charging is performed; and

the controller of the server is configured to control the communication device to transmit the first data to the vehicle when the second data indicates the alternating current charging, and control the communication device to transmit the first data to the direct current electric power supply facility when the second data indicates the direct current charging.

7. The charging system according to claim 6, wherein:

the communication device is configured to communicate with a communication terminal into which the user inputs the instruction; and

the server is configured to receive both of the first data and the second data from the communication terminal.

8. The charging system according to claim 6, wherein:

the communication device is configured to communicate with a communication terminal into which the user inputs the instruction; and

the server is configured to receive the first data from the communication terminal, and receive the second data from the vehicle.

9. The charging system according to claim 6, wherein the server includes a storage device in which a vehicle identification and a direct current electric power supply facility identification are registered in association with each other.

10. The charging system according to claim 9, wherein:

the first data includes the vehicle identification and an expected departure time; and

the controller of the server is configured to transmit the expected departure time to the direct current electric power supply facility registered in association with the vehicle identification when the second data indicates the direct current charging.
