Abstract: 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.

Abstract: A motor vehicle has a motor performing power driving and regeneration. The motor includes an inverter, a first power storage device suppling energy to the motor, a power converter and a circuit. The converter has a voltage step down function during the power driving and a voltage step up function during the regeneration. The power converter, with the voltage step down function during the power driving, is connected in the circuit to the first power storage device. During the power driving of the motor, the power converter steps down an output voltage of the first power storage device to supply the energy from the first power storage device to the inverter. During the regeneration in the motor, the power converter steps up a DC voltage of the inverter to recover regenerated energy into the first power storage device.

Abstract: A motor performing power driving and regeneration has an inverter, a mechanical brake, a power storage device supplying energy to the motor, an accelerator operator controlling the motor to adjust a drive torque of a driving wheel, a mechanical brake operator controlling the mechanical brake to adjust a braking torque, a regenerative brake operator adjusting a braking torque of the driving wheel and recovering the energy into the power storage device, and a detector detecting a rotation speed of the motor. When the rotation speed of the motor is equal to or higher than a predetermined value, a predetermined braking torque, based on an operation amount of the regenerative brake operator, is generated by regenerative braking.
