Abstract:
1. A charging control apparatus adapted to control an alternator which is operable to generate a voltage to charge a battery which is operable to supply the voltage to an electric component, the charging control apparatus comprising: an interface, connected to the alternator, the battery, and the electric component and operable to input and output a signal therebetween; and a microcomputer, connected to the interface and operable to execute a gradual change process in which a generating voltage of the alternator is gradually changed to a target generating voltage of the alternator and a sudden change process in which the generating voltage is suddenly changed to the target generating voltage, wherein: the microcomputer is operable to detect a using status of the electric component based on the signal; the microcomputer is operable to judge whether the gradual change process is required or the sudden change process is required based on the detected using status; the microcomputer executes the sudden change process when the microcomputer judges that the sudden change process is required; the microcomputer executes the gradual change process when the microcomputer judges that the gradual change process is required; the microcomputer is operable to predict the using status based on an external information; and the microcomputer is operable to judge whether the gradual change process is required or the sudden change process is required based on the predicted using status.
