Abstract: A controller, responsive to a command to fast charge a traction battery, initiates a discharge pulse of the traction battery that charges an auxiliary battery, and following the discharge pulse, initiates a charge of the traction battery such that a voltage of the traction battery decreases to a peak minimum value during the discharge pulse and continually increases immediately after the peak minimum value without dwelling at a constant value to preclude rest of the traction battery between the discharge pulse and charge of the traction battery.

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.

Abstract: A vehicle includes a vehicle drive power storage device including a power battery pack and a first capacity battery pack and a second capacity battery pack that has at least a smaller capacity than the first capacity battery pack and supplies electric power to the power battery pack. The power battery pack and the capacity battery packs are coupled in parallel. The capacity battery packs have a higher capacity and lower power than the power battery pack. The vehicle further includes a switch mechanism, a control device, and a load. The control device: preferentially supplies electric power from the power battery pack to the load when the vehicle accelerates; and, when a velocity of the vehicle is constant, supplies electric power from the second capacity battery pack to the power battery pack, concurrently with supplying electric power from the first capacity battery pack to the load.
