摘要

锂离子动力电池组一致性好坏直接影响着电动汽车使用效率。为了方便动力电池组的使用及维护，需采取一定的方法对电池组一致性进行监控。该文提出一种基于单体电池电压值标准偏差的锂离子动力电池组一致性评估方法，并将电池组一致性分为四个阶段，根据不同阶段采用不同的维护策略。实验通过对电动汽车锂离子动力电池组进行充放电测试，采用文中提出的方法获得了四个阶段的电池组一致性评估曲线，为电动汽车电池使用及维护提供指导。

Abstract

The consistency of electric vehicle Lithium-ion

Battery can affect the efficiency of electric vehicle directly. The consistency of battery must be monitored for the use and maintenance of battery. A consistency evaluation method based on standard deviation of cell voltage was proposed. The consistency of battery can be divided into four levels which correspond to four kinds of maintenance strategies. The electric vehicle Lithium-ion

Battery charge-discharge tests were used in the experiments

and the results show that the four consistency curves can be obtained by the method and it can provide a reference for the use and maintenance of battery.
