Abstract

A vehicle includes a motor serving as a driving source configured to run the vehicle, and a high-power and high-capacity assembled batteries, each of the assembled batteries being formed to include secondary batteries configured to supply an electric power to the motor, the secondary batteries of the assembled batteries being housed in different cases. The high-power and high-capacity assembled batteries are arranged around a luggage space located in a rearward portion of the vehicle. The high-power assembled battery is chargeable and dischargeable with a current larger than a current in the high-capacity assembled battery. The high-capacity assembled battery has an energy capacity larger than an energy capacity of the high-power assembled battery. The high-capacity assembled battery is arranged above or below the high-power assembled battery in the vehicle, and at least a portion of the high-capacity assembled battery protrudes from the high-power assembled battery rearward in the vehicle.

Claims

1. A vehicle comprising:

a motor serving as a driving source configured to run the vehicle; and

a high-power and high-capacity assembled batteries, each of the assembled batteries being formed to include secondary batteries configured to supply an electric power to the motor, the secondary batteries of the assembled batteries being housed in different cases, the assembled batteries being arranged around a luggage space located in a rearward portion of the vehicle,

wherein the high-power assembled battery is chargeable and dischargeable with a current larger than a current in the high-capacity assembled battery, and

the high-capacity assembled battery has an energy capacity larger than an energy capacity of the high-power assembled battery and is arranged above or below the high-power assembled battery in the vehicle, and at least a portion of the high-capacity assembled battery protrudes from the high-power assembled battery rearward in the vehicle.

2. The vehicle according to claim 1, wherein, when the high-power assembled battery and the high-capacity assembled battery have an equal temperature, an electric power during charge and discharge of the high-power assembled battery is higher than an electric power during charge and discharge of the high-capacity assembled battery regardless of the temperature.

3. The vehicle according to claim 1, further comprising an engine serving as a driving source configured to run the vehicle,

wherein the high-power assembled battery supplies an electric power to the motor in accordance with an output required of the vehicle while the vehicle is run with the engine or the high-capacity assembled battery, and

the high-capacity assembled battery supplies an electric power to the motor to run the vehicle while the engine is not operated.

4. The vehicle according to claim 1, wherein the high-capacity assembled battery is arranged below and rearward of the high-power assembled battery in the vehicle.

5. The vehicle according to claim 4, wherein the high-power assembled battery is arranged at a position along a back face of a seat adjacent to the luggage space on a floor panel of the vehicle, and

the high-capacity assembled battery is arranged in a recessed portion located below the luggage space and formed in the floor panel.

6. The vehicle according to claim 1, wherein a bottom face of the high-power assembled battery is entirely opposite to an upper face of the high-capacity assembled battery in an up-down direction of the vehicle.

7. The vehicle according to claim 1, wherein the high-power assembled battery has the plurality of secondary batteries connected electrically in series, and

the high-capacity assembled battery has the plurality of secondary batteries connected electrically in parallel.

8. The vehicle according to claim 7, wherein the secondary battery of the high-power assembled battery is a square-type battery, and

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