When a low voltage battery is exhausted, power necessary for starting up is supplied from a simple power supply connected to an ACC socket to a vehicle side. The power of the simple power supply is supplied to power supply terminals of a DC/DC converter and other loads, and is used to activate the DC/DC converter. After the DC/DC converter is activated, power on a high voltage battery side is stepped down and supplied to a low voltage battery side, and a power supply path for the DC/DC converter and the other loads is switched. A mode switch or a relay is used to switch between a normal mode and an emergency start mode.
