Abstract:
A charger converting electric power from an external power supply into charging power for a power storage device converts AC power on a power line into charging power for an auxiliary battery. A CHR connects or disconnects a path between the charger and the power storage device. A DC/DC converter converts DC power on a power line connected to a smoothing capacitor into charging power for the auxiliary battery and outputs the power onto a power line. An ECU discharges the smoothing capacitor even if the voltage on the power line is lower than a determination voltage by causing the DC/DC converter to operate to charge the auxiliary battery in a discharging mode where the CHR is set OFF.
