システムを構成する上で問題となる。However, in the above-mentioned prior art, since the power is supplied collectively to each of the wheel driving motors, when the power battery is exhausted or a failure occurs, all the power is supplied. The power supply to the driving motor is stopped collectively. For this reason, in the case of a hybrid system in which a gasoline engine and a generator other than the secondary battery are provided as motor drive sources, subsequent running cannot be completely performed due to a failure of the power supply battery or the like, and a stable system is configured. The above is a problem.

上での完全停止を回避できる。In the electric vehicle of the present invention as described above, power is separately supplied from the secondary battery to each drive motor. Therefore, even if power supply to the drive motor by one of the secondary battery units is stopped due to battery exhaustion or failure, power supply to the drive motor by another secondary battery unit is not stopped. Therefore, only the wheels driven by the driving motor for which the power supply is secured are used as driving wheels, and the wheels corresponding to the driving motor for which the power supply is stopped are used as driven wheels, so that slow running can be performed incompletely. Can be secured. Thereby, even in the worst case, a complete stop on the road can be avoided.
