A motor vehicle has a motor performing power driving and regeneration. The motor has an inverter, a first power storage device with a large-capacity characteristic, a second power storage device with a high-power characteristic, a power converter and a circuit. The power converter has a voltage step down function during the power driving and a voltage step up function during the regeneration. In the circuit, the power converter, with the voltage step down function during the power driving, is connected to the first power storage device and the second power storage device is connected in series between a reactor of the power converter and the inverter. During the power driving of the motor, an output voltage of the first power storage device is stepped down to supply energy from the first power storage device and the second power storage device to the inverter.
