摘　　要：针对串联电池组在使用过程中存在的电压及容量不一致性问题,提出一种主动均衡方案,该方案以基于改进型Boost电路的均衡器为核心。该均衡器能在均衡能量转移的过程中,利用Boost电路提升输出端电压以增大均衡电流。同时LC谐振电路让开关管导通前两端电压为零,减少开关损耗以提升均衡效率。并且本文在MATLAB/Simulink仿真环境中对均衡器进行仿真验证,仿真结果表明该均衡器的效率能达到80%以上,证明均衡方案可行。In order to solve the problem of voltage and capacity inconsistency in the use of series battery packs, an active equalization scheme is proposed, the scheme is based on an equalizer based on an improved Boost circuit. The equalizer can use the Boost circuit to increase the voltage of the output terminal to increase the equalization current during the process of equalizing the energy transfer. At the same time, the LC resonant circuit is used to make the voltage on the switch to zero before conducting, and the switching loss is reduced and the equalization efficiency improved. And in the MATLAB/Simulink simulation environment, the equalizer is simulated and verified. The simulation results show that the efficiency of the equalizer can reach over 80%, which proves that the equalization scheme is feasible.
