In this paper, a novel integrated system for a battery charger with a state-of-charge estimator is proposed. First, by using a 16-bit MC80196 microprocessor, two different methods for estimating a battery'S state-of-charge are presented. Then, the current of the charger is adjusted according to the estimated result. The charger, which has a zero current switching topology, performs with both a high input power factor and a high efficiency. In addition, the microprocessor effectively integrates the charger and the state-of-charge estimator. Several experimental results validate the theoretical analysis.
