Research of Li-Ion Battery’s Upper Equalizer Circuit

Article Preview

Abstract:

Due to small size, large power density, high individual voltage, low self-discharging, and low internal resistance, li-ion battery substitutes other types of battery used as power supply. In practice, because of difference of every cell, after a period of charge-discharge time, the upper limit voltage of every unit becomes various, seriously affects the system’s performance. The idea of upper equalizer is released, then, a further research is made on the equalizer circuit of li-ion battery. The experiment result proves the correctness of design on li-ion battery equalizer circuits.
