Research on the bidirectional battery pack energy equalizer with a double cuk chopper circuits

A large number lithium-ion batteries serially connected, whose energy will become different in the use of the process due to various reasons. In order to solve this problem, a bidirectional battery pack energy equalizer with a double cuk chopper circuits is suggested in this paper. The energy equalizer proposed in this paper, which has a double cuk chopper circuits and adapts two kinds of energy equalization strategies to transfer bidirectional energy quickly. The principle of equalizer is simple, the current is continuous, the controllability is strong, and the efficiency is high. The simulation experiments of the equalizer has been done and the experimental results has been analyzed.
