Abstract
An AC/DC converter is configured to perform voltage conversion on power supplied from an AC power supply and supply the power to an auxiliary load during external charging in which a main power storage device is charged by the AC power supply. An auxiliary power storage device stores power to be supplied to the auxiliary load. A diode permits discharging of the auxiliary power storage device while preventing charging of the auxiliary power storage device during the external charging. A current sensor detects discharging of the auxiliary power storage device. A controller adjusts an output voltage of the AC/DC converter while confirming whether or not the auxiliary power storage device discharges, based on a detection value of the current sensor.
