摘要
指出串联电池组的不一致性产生的原因。研究了基于拓朴结构分类的集中式均衡充电方法和独立式均衡充电方法,通过对上述方法的对比分析,提出了分散一集中式二级均衡充电方法,它适用于对串联电池数目比较大的混合动力电池组进行均衡充电。用此方法对Ni_MH电池组进行充电均衡仿真实验,结果表明用该方法进行均衡充电效果良好。
The unbalanced phenomena of the charge and discharge of serial batteries and their causes are analyzed. Two ordinary equalizing charge methods are also discussed. Based on the comparison and analysis, a new method ＂dispersion-concentration second-grade equalizing charge＂ is constructed, which is suitable for numerous serial batteries for hybrid electric vehicles. Simulation calculation is processed on serial Ni-MH batteries by this method, and a good-result is obtained.
