ABSTRACT:
To improve charging efficiency of a storage battery and extend the service life of each of vehicle laps, the output voltage of a generator is adjusted to a first voltage value (13.5 V, for example) without grounding a voltage dividing point B when the duty ratio for turning on or off a field current detected by a detector is lower than a predetermined value and to a second voltage value (14.5 V, for example) by grounding the point B when the detected duty ratio is higher than the predetermined value.
