An electric power equipment for a hybrid electric vehicle includes a main battery, an auxiliary battery, an inverter for supplying a prescribed lower-frequency AC power from the main battery to a motor-generator and DC power to the main battery from the rotary electric machine and an auxiliary battery charging circuit. The auxiliary battery charging circuit includes a frequency filter for passing only AC power of a prescribed higher frequency that is too high for the motor-generator to be operated, a rectifier and a controller for controlling the inverter.
