ABSTRACT:
When an AC adapter and a battery are connected to a system, trickle charge is performed with respect to the battery through a trickle charge resistor. During the trickle charging of the battery, the adapter voltage of the AC adapter and the battery voltage of the battery are detected by voltage detectors, respectively. On the basis of a differential voltage representing a difference between the two detected voltages, a power source controller controls the start and stop of the trickle charge at predetermined timings in such a manner that a trickle charge current does not exceed a predetermined value even when the differential voltage increases.
