PROBLEM TO BE SOLVED: To enable the uniform charging of a battery by a motor-generator and eliminate a facility, the maintenance, etc., for the uniform charging. SOLUTION: Potential differences between respective modules 40a in a battery 40 are detected by a sensor 42. If the potential difference exceeds a threshold, a motor-generator 1 is driven by an engine 1 to practice the uniform charging of the battery 40. During the uniform charging, driving wheels are driven by the driving force of an internal combustion engine 1 transmitted through an continuos speed changer M. |
