A restart section in an electric powered vehicle restarts a controller from a sleep mode, when a voltage higher than a restart voltage is supplied for over a response time. In a charge mode, a stand controller provides a connection check function by using a normal CPLT (Control Pilot signal) method. In a normal CPLT method, an output terminal is supplied with DC voltage that exceeds the restart voltage. In a non-charge mode, the stand controller uses a monitor signal which will not cause a restart of the controller to provide a connection check function. The monitor signal for the non-charge mode has a voltage that is lower than the restart voltage and/or a pulse width that is shorter than the response time. As a result, it is possible to reduce power consumption.
