摘要:      电动汽车动力电池的不一致性,缩短了电池的使用寿命,降低了电池的性能,限制了电池组的合理使用。为缓解电池的不一致性,作者构建了电池管理系统,以利于单电池保护的电路设计,并提出了电池组状态估计问题。缓解电池的不一致性的方法有:在设计阶段,合理的热管理系统设计;在使用阶段,单体电压检测、电池均衡等电气保护;在组装阶段,单电池分选。

关键词: 电动汽车, 电池不一致性, 热管理, 单体电池保护, 状态估计

Abstract: The un-uniformity of power batteries used in electrical vehicles (EVs) shorten battery service life,reduce battery system performance,and limit battery packs application. To relief the growth of un-uniformity during battery application, the authors structured a battery management system (BMS) for designing single cell protection circuit,and proposed battery pack state estimation. The technologies to resolve the problem could be as a good thermal management in design stage, an efficient electric protection with cell voltage monitoring and cell balancing typically in using stage, and an appropriate cell classification in assembling stage.

Key words: electrical vehicle (EV), battery un-uniformity, thermal management, cell protection, cell classification, state estimation
