Abstract

An electrically powered vehicle includes a target battery that is externally chargeable and externally power feedable, a sensor that detects a temperature of the target battery, and a controller that performs charging control, discharging control, and temperature increase control of the target battery. The temperature increase control is control for increasing a temperature of the target battery by selecting any of external electric power and battery power and generating heat with the selected electric power. The controller receives a leveling signal that requests for power leveling. When the temperature of the target battery is lower than a first temperature during external power feed requested by the leveling signal, the controller performs the temperature increase control by using battery power before the external power feed requested by the leveling signal.
