摘  要:以6.5 A.h/144 V60QNY6.5镍氢电池组为对象进行效率分析,搭建了混合动力汽车镍氢电池组综合性能实验台,进行了电池组充放电性能实验测试与数据分析;基于镍氢电池组性能实验结果,并考虑电池组环境温度,利用拟合技术得到了镍氢电池内阻与电动势的理论计算模型;结合电池与电机联合工作原理,提出了镍氢电池组效率的理论计算模型,为混合动力汽车系统控制策略的动态优化技术提供了理论基础。The efficiency of the 60QNY6.5 battery is studied by testing and theoretical analysis in order to improve the control precision of hybrid electric vehicles (HEVs) and the battery useful life. A rig for testing the Ni-MH batteries of HEVs is established. The data from experiments performed on the Ni-MH battery are analyzed. Based on the experimental results and the temperature of the batteries, internal resistance and electromotance models of Ni-MH batteries are proposed by function-fitting methods. The theoretic formula for battery efficiency is deduced by the operational principle of the battery and motor, which provides theoretical basis for dynamic optimizing technology of HEV system controlling strategy.
