PROBLEM TO BE SOLVED: To extend the travel distance of an electric car, and to reduce the size and the weight, by using a power control circuit by the use of a switching power circuit for driving auxiliary apparatuses. using a power source in common with a running motor, and simplifying an auxiliary apparatus system. SOLUTION: An A power control circuit 11 is composed of a switching power circuit composed of a chopper circuit or inverter circuit and an A induction coil 11L, depending on an A electric load 12, and performs control by an A control commanding means 13. And the A power control circuit 11 converts the output of a main battery 1, and supplies it to the A electric load 12 directly. Consequently, it becomes possible to simplify the apparatus, and to reduce its size and weight, since connecting distributing wires from the main battery 1 can be partially used in common by power control circuits 11, 21, a power converting apparatus 2 for running motors, and so on. Besides, it is possible to reduce power consumption of the battery, and to extend a travel distance, since power supply to auxiliary apparatuses not in use is stopped. |
