Abstract:
The p roposed charge equalizing circuit (CEC) , which consists of inductor, diode and switching device, performs an equally-charging characteristic for seriesly connected batteries. The operational p rincip le of CEC, which can redistribute excess charging energy, has been analyzed in the paper. Taking advantage of the relationship between the state of charges and the voltage of batteries, the duty ratio of switching device in the CEC can be calculated by u-singmeasured voltage of battery. The whole system of CEC achieves simp le structure, flexibility and extendibility.
