摘　　要：在低碳经济的大背景下,发展纯电动汽车已是大势所趋。电动汽车用电池的一致性问题和SOH预测问题一直是电动汽车技术研究和大规模产业化急需解决的难点之一。以电动汽车用"超威"铅酸蓄电池为例,介绍了电动汽车铅酸电池的SOH及行驶过程中蓄电池的一致性问题,并用电压的一致性对电池的一致性进行评价,进而对电池的健康状态进行一致性修正。Nowadays,Electric Vehicles（ EV） development has become a trend,due to its superiorities on energy saving and environmental protection. Analysis of consistency and SOH of batteries has been the key technology of EV＇s research and mass production. This paper introduces the SOH of lead- acid batteries and the inconsistency of batteries in driving. In consideration of the fact that the inconsistency of cells has a great influence on SOH,the SOH results are corrected based on the inconsistency of cells.

关 键 词：铅酸电池 一致性 SOH
