Abstract

A vehicle includes a first inlet to be connected to a commercial power source, a second inlet to be connected to a battery of an HEMS (Home Energy Management System) which supplies electric power greater than electric power supplied by the commercial power source, and an ECU. The ECU indicates one of the first inlet and the second inlet to a user in accordance with a state of a battery of the vehicle.

Claims

1. A charging system for a vehicle equipped with a power storage device and provided with an outlet for drawing electric power from said power storage device, comprising:

a charging device charging said power storage device in one of a first charging mode and a second charging mode in which electric power greater than electric power supplied in said first charging mode is supplied; and

an indicating device indicating said first charging mode, of said first charging mode and said second charging mode, to a user, when a power cord of an electronic apparatus is connected to said outlet.

2. The charging system for the vehicle according to claim 1, wherein

in said first charging mode, said power storage device is charged by electric power supplied from a first power source, and

in said second charging mode, said power storage device is charged by electric power supplied from a second power source different from said first power source.

3. The charging system for the vehicle according to claim 2, further comprising:

a first connection portion to be connected to said first power source; and

a second connection portion to be connected to said second power source,

wherein, when the power cord of said electronic apparatus is connected to said outlet, said indicating device indicates said first connection portion to the user.

4. The charging system for the vehicle according to claim 2, wherein

said first power source is a commercial power source, and

said second power source is a power storage device arranged outside said vehicle.

15. A power supply system, comprising:

a first supply device supplying electric power from a commercial power source to a vehicle in a first charging mode;

a second supply device supplying electric power from a power storage device to said vehicle in a second charging mode in which the electric power greater than the electric power supplied in said first charging mode is supplied; and

an indicating device indicating said second charging mode, of said first charging mode and said second charging mode, to a user, when said power storage device has a remaining capacity greater than a predetermined value.

17. The power supply system according to claim 15, wherein, when said power storage device has the remaining capacity greater than said predetermined value, said indicating device indicates said second supply device, of said first supply device and said second supply device, to the user.

16. A power supply system, comprising:

a first supply device supplying electric power from a commercial power source to a vehicle in a first charging mode;

a second supply device supplying electric power from a power storage device to said vehicle in a second charging mode in which the electric power greater than the electric power supplied in said first charging mode is supplied; and

an indicating device indicating said first charging mode, of said first charging mode and said second charging mode, to a user, when said power storage device has a remaining capacity smaller than a predetermined value.

19. The power supply system according to claim 16, wherein, when said power storage device has the remaining capacity smaller than said predetermined value, said indicating device indicates said first supply device, of said first supply device and said second supply device, to the user.

18. A power supply method, comprising the step of indicating, of a first charging mode and a second charging mode, said second charging mode to a user, when a power storage device has a remaining capacity greater than a predetermined value, said first charging mode being a charging mode in which electric power is supplied from a commercial power source to a vehicle, said second charging mode being a charging mode in which electric power greater than the electric power supplied in said first charging mode is supplied from said power storage device to said vehicle.

20. A power supply method, comprising the step of indicating, of a first charging mode and a second charging mode, said first charging mode to a user, when a power storage device has a remaining capacity smaller than a predetermined value, said first charging mode being a charging mode in which electric power is supplied from a commercial power source to a vehicle, said second charging mode being a charging mode in which electric power greater than the electric power supplied in said first charging mode is supplied from said power storage device to said vehicle.
