摘　　要：为提高锂电池组均衡速率,降低均衡后的电压不一致性,提出了基于电感的复合型锂电池主动均衡拓扑。组内使用Buck-boost电路,组间使用单电感电路,同时结合相应的主动均衡策略,在Matlab/Simulink中建立了9节串联锂电池组模型,对比Buck-boost、单电感电路以及复合型拓扑均衡实验表明:复合型主动均衡拓扑有效降低了均衡时间和电压离散度。In order to improve the equalization rate of lithium battery pack and reduce the voltage inconsistency after equalization,this paper proposes an active balancing topology of composite lithium battery based on inductance.The Buck-boost circuit is used in the group,and the single inductor circuit is used between the groups.At the same time,combined with the corresponding active equalization strategy,a model of nine series lithium battery packs is established in Matlab/Simulink.Compared with the Buck-boost,single inductor and the composite topology equalization effect were designed in this paper.Experiments indicate that the composite active balancing topology in this paper effectively reduced equalization time and voltage dispersion.
