Abstract
An electric load is electrically connected to a path between an external power supply and a power storage device. An ECU executes temperature-rise control, when the temperature of the power storage device is low, ensuring power consumption of the electric load in association with charging/discharging of the power storage device. During execution of temperature-rise control, the ECU sets a power command value of the external charger, alternately causing a discharging mode having the output power of the external charger positively controlled and in which power consumption of the electric load is ensured in association with discharging of the power storage device, and a charging mode having the output power of the external charger negatively controlled and in which power consumption of the electric load is ensured in association with charging of the power storage device.
