摘　　要：在分析常用电池模型的基础上,利用实验建模和电路等效建模相结合的方法改进了传统的蓄电池模型,改进的电池模型对蓄电池荷电状态(SOC)的实时计算更加方便;依据电池的荷电状态参数提出了一种基于分组的蓄电池组能量管理方法.试验结果表明改进的电池模型使得电池荷电状态的计算有较好的精确性;分组系统在能量管理策略上优于未分组系统,能在一定程度上延长蓄电池的使用寿命.By combination of experimental modeling with equivalent circuit modeling,a traditional battery model is improved,by which the real-time calculation of battery state of charge （SOC） is done more conveniently.A packet-based batteries energy management strategy which is based on SOC is also presented.The results have shown that battery SOC is calculated much more accurate and the new strategy performs better than the traditional method.To some extent,the battery life has been extended.
