In order to simplify a door lock operation by a user after starting an energy supply receiving operation, an ECU mounted on a vehicle stores an ID code beforehand. Furthermore, ECU locks all the doors, if a charging paddle on the power supply device side is connected with a charging plug on the vehicle side, and if an ID code received from the power supply device matches the ID code stored beforehand, and if a drive system of the vehicle is stopped, and if all the doors of the vehicle are closed.
