【摘要】：针对串联蓄电池组单体电池间存在的不一致性问题,改进了一种基于Buck-Boost均衡电路的均衡控制策略。由于传统的均衡控制策略对某些特殊情况的电池组不一致状态均衡效果不理想,采用最值比较法与相邻差值比较法相结合的均衡控制策略,可有效改善电池组的不一致性,并得到仿真实验对比验证。最后通过对6节镍镉蓄电池的均衡充电,结果表明该均衡策略能有效减小电池组极差,避免不一致性的扩大,提高电池组容量利用率。
[Abstract]:An improved equalization control strategy based on Buck-Boost equalization circuit is proposed to solve the problem of inconsistency between single cells in series batteries. Because the traditional equalization control strategy is not ideal for the inconsistent state of the battery pack in some special cases, the equalization control strategy which combines the maximum comparison method and the adjacent difference comparison method can effectively improve the inconsistency of the battery pack. The simulation results are compared and verified. Finally, through the balanced charging of 6 Ni-CD batteries, the results show that the equalization strategy can effectively reduce the range of the battery pack, avoid the expansion of the inconsistency, and improve the capacity utilization ratio of the battery pack.
