An electric automobile driving apparatus installed in an electric automobile for driving the same. The driving force of the electric automobile is generated by a main battery as the rotating force of a motor. The motor is an AC motor and driven by an AC current output from the main battery and converted into a DC voltage by an inverter. Electric appliances installed in the automobile are driven by a DC voltage having a different value which is output from an auxiliary battery. The auxiliary battery is charged with the DC voltage obtained by rectifying the output from a secondary coil which is disposed in close proximity to a primary coil of the motor.
