To detect an error of an attaching position of a sensor that detects rotation of a rotor of a generator. A battery charging apparatus includes a position sensor 42 that outputs a position detection signal that expresses a rotation position of a rotor 12 of a generator 10, a sensor that detects an output current or an output voltage of a predetermined phase, a regulator 20 that includes a plurality of rectifying elements and a plurality of switching elements and supplies DC power obtained by rectifying three-phase AC outputted from the generator 10 to a battery 24, and an inverter control section 30 that executes energization control of the respective switching elements of the regulator 20 based on a phase of an induced voltage of the generator 10 calculated on the basis of the position detection signal. The inverter control section 30 inputs a revolution speed signal Ne that shows a revolution speed of the generator 10, 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 42 with respect to the induced voltage of the predetermined phase based on the position detection signal and the output signal.
