摘　　要：电池的SOH(State of health)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。介绍了电动汽车用铅酸蓄电池SOH的影响因素和常用预测方法,提出用定期测量法对SOH进行预测,并对结果进行一致性修正,具有重要的实际意义。SOH estimation is the key technology of EV's research and mass production.The influencing factors,traditional estimation methods of SOH,and a new method based on periodic test were introduced.In consideration of the fact that the inconsistency of cells had a great influence on SOH,the SOH results were corrected based on the inconsistency of cells.

关 键 词：电动汽车 SOH 一致性
