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 a current relatively larger than that in the high-capacity assembled battery, and the high-capacity assembled battery has 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 supplies a more electric power to the motor than that in the high-power assembled battery. The high-power assembled battery is placed in a riding space where a passenger rides, and the high-capacity assembled battery is placed in a luggage space different from the riding space.
