摘　　要：针对锂电池成组后使用寿命缩短、安全性能降低等问题,对成组后的锂电池的工作特性做出研究分析。对航空用锂电池进行建模并基于扩展卡尔曼滤波算法估计其剩余电量。通过对电池成组前后进行常温下9 A充电、45 A放电以及循环充放电等实验测试,绘制出锂电池组及单体的性能曲线图,分析锂电池组的工作特性。实验结果表明:成组后锂电池的工作特性不同于单体的特性。该研究能更好地推进锂电池的成组应用,同时为航空用动力锂电池组的检测维护和健康管理提供很好的研究基础和依据。For the problems of the shorten service life and the reduced security, the work characteristics of the lithium batteries after grouped was studied. The aeronautical lithium battery was modeled and the remaining capacity was estimated based on the extended Kalman filter. Charge-discharge experiments at normal temperature were done, including 9.0 A charge, 45 A discharge and cycle test. The performance curve graphs of lithium battery pack and cell were drawn, and the working characteristics of the lithium battery pack were analyzed. The experiment results show that there are difference between the lithium batteries after grouped and cell. The research can better promote the group application for lithium batteries and provide research foundation and basis for the health management and maintenance of aeronautical lithium power battery pack.
