る電気自動車の電源回路。 Electricity equipped with a rectifier circuit that rectifies AC power supplied from the outside to charge a battery, and a DC/DC converter that converts the rectified voltage into a battery charging voltage and a driving voltage for auxiliary equipment. In the power supply circuit of an automobile, the DC/DC converter has a transformer consisting of a primary winding, a secondary winding for charging, and a secondary winding for auxiliary equipment. a first switching circuit that connects a winding and a battery to charge the battery; and a first switching circuit that supplies discharged power from the battery to the input side of the DC/DC converter while the vehicle is running and supplements the secondary winding. A second switching circuit connected to the equipment is provided, and by selectively switching and connecting each of the switching circuits when charging the battery and when the vehicle is running, the DC/DC converter is shared during charging and discharging. An electric vehicle power supply circuit characterized by
