An HV-ECU continuously integrates period of no external charge as the time elapsed from latest external charging (last external charging). When ignition is turned on, a stored map is looked-up, and an SOC control center value that corresponds to the period of no external charge is obtained. Charge/discharge management of the power storage unit in HV running mode is executed based on the obtained SOC control center value. When the period of no external charge exceeds a prescribed threshold value, SOC control center value is increased to control center value.
