In an electric vehicle, an automatic transmission (30) is provided between a differential unit (20) and drive wheels (44). The differential unit (20) includes a motor-generator and a power split device, and the motor-generator is cooled by lubricant of the automatic transmission (30). A battery charger (56) is operable to charge a power storage device (54) using a power supply outside the vehicle. When the temperature of the lubricant is lower than a predetermined temperature upon execution of charging of the power storage device (54) using the charger1 (56), and the automatic transmission (30) is in a neutral state, or a power cutting-off state, the controller (60) rotates the motor-generator of the differential unit (20) so as to perform warming control for raising the temperature of the lubricant.
