摘要
提出了基于实车运行数据的动力电池动态测试工况统计方法,应用该方法建立了基于北京公交的纯电动客车用动力电池动态测试工况,为测试动力电池的动态性能及评价动力电池在对应工况下的适用性奠定了基础.对工况进行了标准化,并提出该工况应用于不同车型和不同电池组的等价方法,最后对比了电池在动态工况和恒流工况下的性能.结果表明,动态工况测试包含了电池动态直流内阻等信息,可以反映电池的动态性能.
A method to get the traction battery dynamic performance test procedure is developed, which was based on actual running data statistic. The Beijing bus dynamic stress test（BBDST） cycle was established with this method. Thus dynamic performance test and its applicability evaluation for some applications become feasible. The standardized BBDST can be used for different vehicle types and variable battery pack with the battery size parameter. Practical use of BBDST procedure indicates more dynamic information of battery can be obtained through constant current discharge.
