Abstract
The battery voltage regulating system for vehicle use of this invention controls the energization of an alternating-current generator by a generation control circuit responsive to a battery voltage in normal operation. However, if a fault condition such as the damage of a resistor of the generation control circuit or a break in the warning line occurs, and even if the resulting warning is ignored or over-looked by the driver, a warning control circuit provided a requisite control to regulate the generator's generation while giving a warning. In this manner, an average voltage of a battery is kept substantially equal to a predetermined constant value controlled by said generation control circuit even if such unexpected situation occurs. Thus, the battery voltage regulating system can prevent the battery from being excessively charged.
