Abstract

A charger is configured to charge a power storage device. An ECU is configured to control charging of the power storage device by the charger. While charging of the power storage device is not executed, the ECU operates in a sleep mode in which power consumption is smaller than that in a wakeup mode in which charging control is being executed, until a pilot signal is detected. After charging of the power storage device is ended, the ECU operates in an intermittent activation mode in which a wait mode and the wakeup mode are regularly switched to each other, until stoppage of oscillation of the pilot signal is detected.

Claims

1. A charging control apparatus for a vehicle configured in such a manner that a power storage device mounted on the vehicle is chargeable by a power supply located externally to the vehicle, comprising:

a charging device configured to charge said power storage device; and

a controller configured to control charging of said power storage device by said charging device,

while charging of said power storage device is not executed,

said controller operating in a sleep mode in which power consumption is smaller than that in a normal mode in which charging control is being executed, before a predetermined first signal indicating a user'"'"'s intention to request charging is detected,

said controller operating in an intermittent activation mode in which said sleep mode and said normal mode are switched to each other, after charging of said power storage device is ended, until a predetermined second signal indicating a user'"'"'s intention to end charging is detected.

2. The charging control apparatus for a vehicle according to claim 1, wherein said controller operates in a first sleep mode in which a main clock is stopped and said first signal is to be accepted as hard interrupt, until said first signal is detected, and said controller in said intermittent activation mode regularly switches between a second sleep mode in which said main clock is operated and said normal mode.

3. The charging control apparatus for a vehicle according to claim 2, wherein

said controller switches to said normal mode in response to detection of said first signal during said first sleep mode,

said controller switches to said intermittent activation mode in response to ending of charging of said power storage device, and

said controller switches to said first sleep mode in response to detection of said second signal.

4. The charging control apparatus for a vehicle according to claim 1, wherein said first signal is a pilot signal which is input to said vehicle in response to connection, to said vehicle, of a charging cable for transmitting electric power from said power supply to said vehicle.

5. The charging control apparatus for a vehicle according to claim 1, wherein said first signal is a signal indicating that a charging cable for transmitting electric power from said power supply to said vehicle is being connected to said vehicle.

6. The charging control apparatus for a vehicle according to claim 1, wherein said first signal is a signal indicating that a lid of said vehicle to be connected with a charging cable for transmitting electric power from said power supply to said vehicle has become an open state.

7. The charging control apparatus for a vehicle according to claim 1, wherein

in response to connection, to said vehicle, of a charging cable for transmitting electric power from said power supply to said vehicle, a pilot signal is input to said vehicle, and

said second signal is that said pilot signal does not oscillate or is not input.

8. The charging control apparatus for a vehicle according to claim 1, wherein said second signal is a signal indicating that a charging cable for transmitting electric power from said power supply to said vehicle is not being connected to said vehicle.

9. The charging control apparatus for a vehicle according to claim 1, wherein said second signal is a signal indicating that a lid of said vehicle to be connected with a charging cable for transmitting electric power from said power supply to said vehicle has become a closed state.

10. A vehicle comprising:

a charging control apparatus for a vehicle recited in claim 1; and

a power storage device charged by said charging control apparatus.
