Battery string is widely used in UPS system. The state of charge (SOC) is one of the important parameter of the batery status. Online estimation of battery SOC contributes to the battery condition diagnosis, maintenance, and ensures the battery string power supply safety. With VRLA batteries charge and discharge experiments, battery SOC voltage - resistance calculation model is proposed by the least squares method, and the optimal estimation of SOC is obtained by the Kalman filter algorithm. The battery SOC optimal estimation results of the experiment and simulation are very accurate, which shows that this method can be used to estimate the battery SOC in engineering field.
