Abstract

A vehicle has a motor and an engine each serving as a driving source for running the vehicle, and assembled batteries each capable of supplying an electric power to the motor. The assembled batteries include a high-power assembled battery and a high-capacity assembled battery. The high-power assembled battery is capable of charge and discharge with current relatively larger than that in the high-capacity assembled battery, and the high-capacity assembled battery has energy capacity relatively larger than that of the high-power assembled battery. In running of the vehicle using output from the motor with the engine stopped, the high-capacity assembled battery supplies more electric power to the motor than that in the high-power assembled battery. The high-power assembled battery is placed in a vehicle-inside space accommodating a passenger or baggage, and the high-capacity assembled battery is placed in a vehicle-outside space located on an outer face of a vehicle body.

Claims

1. A vehicle comprising:

a motor and an engine each serving as a driving source for running the vehicle; and

a high-power assembled battery and a high-capacity assembled battery each capable of supplying an electric power to the motor, the high-power assembled battery and the high-capacity assembled battery constituted by secondary batteries, respectively,

the high-power assembled battery being capable of charge and discharge with a current relatively larger than that in the high-capacity assembled battery,

the high-capacity assembled battery having an energy capacity relatively larger than that of the high-power assembled battery,

in running of the vehicle using an output from the motor with the engine stopped, the high-capacity assembled battery supplying a more electric power to the motor than that in the high-power assembled battery,

wherein the high-power assembled battery is placed in a vehicle-inside space accommodating a passenger or baggage, and

the high-capacity assembled battery is placed in a vehicle-outside space located on an outer face of a vehicle body.

2. The vehicle according to claim 1, wherein, in running of the vehicle using the output from the motor with the engine stopped, a frequency of use of the high-capacity assembled battery is higher than a frequency of use of the high-power assembled battery.

3. The vehicle according to claim 1, wherein, in running of the vehicle using the output from the motor with the engine stopped, a proportion of the electric power supplied from the high-capacity assembled battery to the motor in the electric power supplied to the motor is higher than a proportion of the electric power supplied from the high-power assembled battery to the motor.

4. The vehicle according to claim 1, wherein the high-capacity assembled battery is replaced at a frequency higher than that of the high-power assembled battery.

5. The vehicle according to claim 1, further comprising a power-receiving portion receiving an electric power for use in charging the high-capacity assembled battery from a power-transmitting portion placed outside the vehicle, the power-receiving portion being placed at a position adjacent to the high-capacity assembled battery.

6. The vehicle according to claim 1, wherein the high-capacity assembled battery has a size larger than that of the high-power assembled battery.

7. The vehicle according to claim 1, wherein the high-capacity assembled battery has a weight heavier than that of the high-power assembled battery, and

the high-capacity assembled battery is attached to a surface of a floor panel, the surface facing outside the vehicle.

8. The vehicle according to claim 1, wherein the high-power assembled battery has a plurality of cells connected in series, and

the high-capacity assembled battery has a plurality of cells connected in parallel.

9. The vehicle according to claim 8, wherein the cell of the high-power assembled battery is a square-type cell, and

the cell of the high-capacity assembled battery is a cylinder-type cell.
