PROBLEM TO BE SOLVED: To provide a car motor driving method and system which works for any batteries each having different electric potential. SOLUTION: A step-up circuit unit 5 is switched, according to the electric potential 12 V or 36 V of each battery in each car, to be connected to a battery 2 for boosting its electric potential of 12 V. Namely, a battery 3 is directly connected to an electric-to-mechanical-energy converting section 4 in a car equipped with the battery 3 for the higher electric potential 36 V, and the step-up circuit 5 is connected between the battery 2 and the electric-to- mechanical-energy covering section 4 in a car equipped with the battery 2 for the lower electric potential 12 V. |
