Abstract
A charger converts electric power supplied from an AC power supply external to a vehicle into a predetermined charging voltage. A relay is provided between the charger and a power storage device. A charging ECU controls the charger and the relay. An AC/DC converter converts electric power supplied from the AC power supply into a predetermined power supply voltage and supplies the electric power converted into the power supply voltage to a charging device constituted of the charger, the relay and the charging ECU. While the power storage device is charged by the AC power supply, the charging device operates with the operating electric power it receives from the AC/DC converter.
