A vehicle includes a charging inlet for connection with a ground line and a pair of power lines used to charge an electrical storage device from outside the vehicle; a terminal of the charging inlet for connection with the ground line; and a GND relay that connects the terminal to a body earth of the vehicle. Desirably, the vehicle further includes an ECU that controls charging of the electrical storage device. Before charging of the electrical storage device is started after the pair of power lines and the ground line are connected to the charging inlet, the ECU opens the GND relay and then determines whether there is a disconnection in the ground line.
