摘要
简要介绍了搭载磷酸铁锂电池的电动汽车电池管理系统与整车的关系,分析了磷酸铁锂电池的充放电特性,阐述了电池管理系统的结构,对于电池电量(SOC)的估算做出阐述,根据应用经验估算出电池可循环使用寿命(SOH),通过大量实验数据说明了电池的充放电特性,这些特性对于电池管理系统的开发具有积极意义。
The essay mainly recommends the relationship of battery management system of phosphoric acid iron of lithium battery and vehicle control system and the working characteristic of the battery,and introduces the construction of battery management system and arithmetic of state of charge(SOC),the state of health(SOH) can be estimated based on the experience.The paper also expatiates the speciality of charge and discharge state,which are critical to the exploration of battery management system.
