1. A motor vehicle comprising:
a motor performing power driving and regeneration;
an inverter converting a direct current into an alternating current;
a first power storage device with a large-capacity characteristic;
a second power storage device with a high-power characteristic;
a powerconverter having a voltage step down function during the power driving; and
a circuit where the power converter is connected to the first power storage device and the second power storage device so that the first power storage device and the second power storage device are parallel to each other,
wherein, during the power driving of the motor, the power converter steps down an output voltage of the first power storage device to supply energy from the first power storage device and the second powerstorage device to the inverter,
wherein the power converter has the voltage step down function during the power driving and a voltage step up function during the regeneration, and
wherein, during the regeneration in the motor, the power converter steps up a DC voltage of the inverter to recover the energy into the first power storage device and the second power storage device.
