<p>PURPOSE:To recover a battery charging rate rapidly and increase accuracy of alternator control when the battery charging rate lowers and the detected current difference of the alternator becomes a specified level or more by fixing the generating voltage of the alternator at the high voltage side. CONSTITUTION:A first lead wire 3 is connected to an output terminal 2 of an alternator 1 driven by an engine and diverted to 2nd and 3rd lead wires 5, 6 at a branch 4. The 2nd lead wire 5 is connected to a positive terminal of various kinds of electric devices 7 and the 3rd lead wire 6 is connected to a positive terminal of a battery 8. In this case, the generating voltage of the alternator 1 is set either one of the high-voltage side or low-voltage side by a control unit 9 through a regulator 10. Namely, a non-contact type current sensor 11, etc., is provided to detect the current passing through the 1st lead wire 3, i.e., the output current of the alternator 1. In the control unit 9, the generating voltage is fixed at the high voltage side when a charging rate of the battery 8 is lowered.</p> |
