锂电池成组不一致性研究
|
摘要
锂离子电池的不一致性会影响电池组的使用寿命,降低了电池成组后的性能。锂电池成组不一致性是指单体电池的容量、电压、内阻、自放电速率等参数存在差异,是由电池组的组合结构、使用工况、使用环境、电池管理不同所致。对单体电池分选制度、电池组连接方式、BMS均衡控制、充放电策略和热管理提出了改进方法。
The life time of the battery was influenced by the batteries' inconsistency, and the performance of batterygroup was reduced. The group inconsistency of lithium battery refers to the difference in the capacity, voltage,internal resistance, self-discharge rate and other parameters of the single battery, which is caused by the differentcombination structure, operating conditions, operating environment and battery management of the battery group.The improvement methods of single cell sorting system, battery connection mode, BMS balance control, chargingand discharging strategy and thermal management were proposed.
