ABSTRACT:
A charging control apparatus for a vehicle, which controls a power generation of an AC generator for charging a battery, comprises: a switching circuit connected in series to a field winding of the generator; a comparator for detecting a voltage of a battery and comparing the battery voltage with a sawtooth wave of a predetermined period; a memory device for storing a value regarding a duty factor of an output of the comparator at the same period as the predetermined period of the sawtooth; a control value increasing/decreasing circuit for increasing or decreasing a control value as an output, thereby making the stored value coincide with the control value; and an AND circuit to calculate AND of the control value and an output of the comparator. By controlling the switching circuit by an output of the AND circuit, when an electric load is applied the duty factor of a pulsed field current which is supplied to the field winding is gradually increased from the present value of the duty factor, thereby preventing a sudden increase of a load onto the engine.
