Charging system for vehicle, method for charging vehicle, power supply system, and power supply method
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.
1. A charging system for a vehicle equipped with a power storage device and provided with an outlet drawing electric power from said power storage device and supplying the electric power drawn from said power storage device to an electronic apparatus outside the vehicle, a power cord of the electronic apparatus being detachable from the outlet, the power storage device being mounted on the vehicle, the system comprising:
a charging device configured to charge said power storage device in one of a first charging mode and a second charging mode such that electric power supplied in said second charging mode is greater than electric power supplied in said first charging mode; and
an indicating device configured to indicate a selection of said first charging mode to a user when the power cord of the electronic apparatus outside the vehicle is connected to said outlet.
2. The charging system for the vehicle according to claim 1 , wherein:
in said first charging mode, said charging device is configured to charge said power storage device by electric power supplied from a first power source, and
in said second charging mode, said charging device is configured to charge said power storage device by electric power supplied from a second power source that is 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.
5. The charging system for the vehicle according to claim 1 , wherein the indicating device indicating the selection of the first charging mode to the user when the power cord is connected to the outlet includes where the indicating device instructs the user to use the first charging mode instead of the second charging mode.
6. A method for charging a vehicle equipped with a power storage device and provided with an outlet drawing electric power from said power storage device and supplying the electric power drawn from the power storage device to an electronic apparatus outside the vehicle, a power cord of the electronic apparatus being detachable from the outlet, the power storage device being mounted on the vehicle, the method comprising the steps of:
determining a state of said power storage device; and
indicating one of a first charging mode and a second charging mode to a user such that electric power supplied in said second charging mode is greater than electric power supplied in said first charging mode and a selection of said first charging mode is indicated when the power cord of the electronic apparatus outside the vehicle is connected to said outlet.
7. The method according to claim 6 , wherein indicating the selection of the first charging mode to the user when the power cord is connected to the outlet includes instructing the user to use the first charging mode instead of the second charging mode.
