摘　　要：针对基于剩余容量的电池使用能力描述方法不能线性对应车辆行驶里程的问题,分析了电池充放电能量的计算方法和影响因素,通过建立单体电池能量状态(State Of Energy,SOE)的定义和估算方法,提出了电池组最大可用能量的概念和串联电池组SOE估算方法,为纯电动汽车行驶里程的准确估算和串联电池组均衡维护提供理论依据.The methods which describe battery using ability based on remaining capacity can not linearly correspond to vehicle mileage. To solve this problem, the calculation method of battery charge/discharge energy is described, and the effects on battery energy are also analyzed in this paper. The definition and estimation of single cell state of energy （SOE） are addressed. The maximum available energy of the battery pack is introduced. The SOE estimation of battery pack in series method based on maximum available energy is proposed, which can provide the foundation for EV mileage estimation and battery pack balancing.
