摘　　要：针对锂电池成组后,普遍存在组内单体的不一致性现象,分析了造成电池组不一致的内部原因和外部原因,对7ICP45航空锂离子蓄电池组进行充放电等实验,从容量、充放电倍率、电压均衡等角度,分析、总结电池组不一致的表现规律。实验结果表明:锂电池组单体不一致性外在表现明显。本研究能够进一步推进锂电池成组的应用,为航空用动力锂电池的检测维护和健康管理提供了研究依据。For lithium batteries, the inconsistency of the monomer in the group was analyzed, and the internal and external causes of the battery were analyzed. In the 7ICP45, the performance of the battery pack is analyzed fiom the aspects of capacity, charge and discharge rate, voltage balance and so on, to summarize the performance of battery. The experimental results show that Lithium battery monomer inconsistent obvious external manifestations. This study can further promote the application of lithium batteries into groups, and provide a basis for the detection and maintenance and health management of aviation power lithium battery.
