Abstract:	In this paper, a duty-varied pulse charge strategy (DVPCS), that can detect and dynamically track the optimal duty of the charge pulse, is proposed to improve the battery charge performance. To assess the system performance, a prototype of the duty-varied pulse charger (DVPC) is designed and implemented. Comparing with the standard constant-current and constant-voltage charge strategy, the charge speed of the proposed DVPCS is improved about 14%, while the proposed DVPCS is improved about 5% comparing with the conventional duty-fixed pulse charge strategy (DFPCS). The results indicate that the DVPCS can actually provide pulse with optimal duty to charge the battery and the charge response is improved.
