Abstract

The resistance-compensated phase-locked battery charger (RC-PLBC) proposes as a new and fast charging circuit topology for Li-ion battery in this paper. The circuit topology of the proposed RC-PLBC is not only the same as that of a phase-locked loop (PLL) but also can compensate the pack resistance of Li-ion batteries. Therefore, a complete charging process, consisting of three sub-processes: bulk current charge, variable current charge and float charge, can be automatically implemented with fast charging behavior. The mathematical model of the proposed RC-PLBC is driven, and then the stability of the RC-PLBC is discussed. After that, a complete circuit design procedure is presented to guild the engineer to design a desired RC-PLBC. Finally, a prototype of RC-PLBC is designed according the presented design procedure and realized to verify the charging performance. Comparing with a typical phase-locked battery charger, the charge speed of the proposed RC-PLBC is improved by 18% as well as the safety is held on.
