PURPOSE:To protect a battery from being overcharged or overdischarged by operating a charging amount of battery based on a detected value from a current sensor and the terminal voltage of the battery under a battery charging amount measuring mode. CONSTITUTION:Under battery charging amount measuring mode, a control circuit 5 stops control of an inverter circuit 4 to conduct a switch circuit 22, records a detected value from a current sensor 23 and the terminal voltage of a battery 3, and operates a battery charging amount based on the detected value and the terminal voltage thus recorded. Consequently, charging amount of battery 3 is detected accurately and deceleration and acceleration modes can be utilized effectively. This constitution reduces fuel consumption and protects the battery 3 against overcharge or overdischarge.
