초록 ▼

In a charging control apparatus for a vehicle for controlling generation of electric power from a vehicle\s generator charging a battery, the rate of increase in the field current of the generator is increased when an electrical load is connected to the generator. A switch is connected in series with the field winding, and a mean conduction rate detector detects the mean conduction rate of the switch and generates an output signal having a value which is a function of the mean conduction rate of the switch. A maximum signal generator generates an output signal having a value larger by a predetermined value than that of the output signal of the mean conduction rate detector, and a comparator is enabled to operate while the maximum signal generator is generating the maximum signal. The comparator is preferably enabled again when the value of the mean output signal of the conduction rate detector exceeds a preset value. The predetermined value is preferably increased with the increase in the mean conduction rate of the switch. By enabling the comparator operate depending on the value of the maximum signal, the mean conduction rate of the switch can be gradually increased after it is increased by a predetermined value. The comparator is enabled when the value of the output signal of the mean conduction rate detector attains preset value, and the battery can be quickly charged when the mean conduction rate exceeds the preset value. Because the predetermined value is increased with an increase in the mean conduction rate, the battery can be quickly charged according to the mean conduction rate while decreasing the burden on the engine.
