Abstract
When the output voltage of a vehicle battery is lower than a lower limit value of an activation voltage, a power storage is charged with electric power supplied from the outside to a contactless power receiver, and thus the electric power stored in the power storage is supplied to a controller via a discharger to enable the controller to be activated. After the controller is activated, the controller causes a battery relay to be connected using the electric power supplied from the power storage via the discharger. Electric power is supplied from a high voltage battery to the vehicle battery to enable the vehicle battery to output a voltage higher than or equal to the lower limit value and enable a plurality of relays to be connected.
