Abstract :
Presented in this paper is a lead-acid battery charger featuring high power conversion efficiency, high charging efficiency, and short charging time. In the experiments on 12 V/4.5 Ah nonspillable lead-acid assembled batteries, the charging capacity is 3.71 Ah in 40 minutes and the discharging capacity is 3.5 Ah in 90 minutes. Charging efficiency is 94.3%. The charging time is no more than 10 minutes from empty to 50% of full charge and less than 30 minutes from empty to 80% of full charge.
