阀控式铅酸（VRLA）蓄电池组作为配电终端的后备电源，在保障配电可靠性中发挥着重要作用。长期运行在恶劣环境、缺乏必要的维护，蓄电池性能下降迅速难以发挥应有的作用。因此在线监测蓄电池组的健康度（SOH）是至关重要的。由于电池电化学非线性和动态特性，要准确评估电池SOH一直以来都是相当困难的事。本文根据蓄电池组放电曲线特性，提出了一种切实可行的在线评估蓄电池组健康情况的方法，具有较大的经济价值。

VRLA battery as a backup power of distribution terminal plays an important role in ensuring the reliability of distribution system. A long-term operating in harsh environments and lacking of necessary maintenance make the battery performance decreasing rapidly. So it is essential to conduct online monitoring state of health (SOH) of the batteries. Because of the nonlinear and dynamic characteristics of the electrochemical cell, it is dififcult to accurately evaluate SOH of the battery. Based on the battery discharge curve characteristics, we propose a practical online evaluation method of SOH of battery, which has great economic value.
