Abstract

When a prescribed operation is performed during execution of AC charging, an ECU of a vehicle performs a charging stop process. The ECU determines whether or not a resume condition is satisfied during the charging stop process. When the resume condition is satisfied and when a charging connector is connected to an inlet, the ECU brings a locking device to a locked state and resumes the AC charging. When the resume condition is not satisfied or when the charging connector is not connected to the inlet, the ECU does not resume the AC charging.

First claim

What is claimed is:

1. A vehicle that performs external charging to charge a power storage device mounted on the vehicle, using electric power supplied through a charging cable from a power supply external to the vehicle, the vehicle comprising:
an inlet to which a connector provided in the charging cable is connectable;
a locking device that switches between a locked state and an unlocked state, the connector connected to the inlet being not able to be removed from the inlet in the locked state, the connector connected to the inlet being able to be removed from the inlet in the unlocked state; and
a controller that permits execution of the external charging when the locking device is in the locked state, wherein
when the controller detects that the connector is connected to the inlet, the controller brings the locking device to the locked state,
when a prescribed operation is performed during execution of the external charging, the controller brings the locking device to the unlocked state and stops the external charging, and
when a predetermined resume condition is satisfied within a prescribed time period after the external charging is stopped, and when the connector is connected to the inlet, the controller brings the locking device to the locked state and resumes the external charging.

2. The vehicle according to claim 1 , wherein
when the resume condition is not satisfied within the prescribed time period, the controller does not resume the external charging.

3. The vehicle according to claim 1 , wherein
the resume condition includes at least one of a condition that a door of the vehicle has been opened and a condition that the door of the vehicle has been closed.

4. The vehicle according to claim 1 , further comprising a door lock device that prohibits opening and closing of a door of the vehicle, wherein
the resume condition includes a condition that an operation for bringing the door lock device to a door-locked state has been performed.

5. The vehicle according to claim 4 , wherein
the prescribed operation includes a door-unlock operation for releasing the door-locked state of the door lock device.

6. The vehicle according to claim 1 , further comprising an antenna that transmits a signal to a smart key of the vehicle, the smart key being located within a prescribed range from the vehicle, wherein
the resume condition includes a condition that the smart key has moved from within the prescribed range to outside the prescribed range, and
when the controller receives, from the smart key, a response signal to the signal transmitted through the antenna, the controller determines that the smart key is located within the prescribed range, and when the controller does not receive the response signal from the smart key, the controller determines that the smart key is located outside the prescribed range.

7. The vehicle according to claim 6 , wherein
the smart key is provided with a first release switch that brings the locking device to the unlocked state, and
the prescribed operation includes an operation of the first release switch.

8. The vehicle according to claim 1 , further comprising a second release switch that brings the locking device to the unlocked state, wherein
the prescribed operation includes an operation of the second release switch.
