A battery charging apparatus includes a position sensor for outputting a position detection signal, a sensor for detecting an output current or voltage of a predetermined phase, a regulator for supplying DC power obtained by rectifying three-phase AC from the generator to a battery, and an inverter control section for executing energization control of the respective switching elements of the regulator based on a phase of an induced voltage of the generator calculated on the basis of the position detection signal. The inverter control section inputs a revolution speed signal Ne of the generator, the position detection signal Tp, and either output signal out of a current signal or a voltage signal detected by the sensor, and estimates an error of an attaching position of the position sensor with respect to the induced voltage of the predetermined phase based on the position detection signal and the output signal.
