Abstract: A motor vehicle has a first power storage device 4, a second power storage device 5, a power converter 10, a first switch S3 connects the converter 10 to an inverter 2, not through the second power storage device 5, a second switch S4 connecting the power converter 10 and the inverter 2 via the second power storage device 5. A third switch S5 connects the second power storage device 5 and a ground.
During stopping and/or power driving of the motor 1, the first switch S3 is set to a connected state, the second switch S4 is set to a disconnected state, and the third switch S5 is set to a connected state. Thus, energy is supplied from the first power storage device 4 to the second power storage device 5 while an output voltage of the first power storage device 4 is stepped down.
