| Abstract: | SOC estimation of LiFePO4 Li-ion batteries has an important impact on battery life. Therefore, based on comple-ting the experiment of battery characteristics, this paper presents a method to accurately estimate SOC of LiFePO4 Li-ion batteries, which is based on Ah measurement method and applies open-circuit voltage method to reduce the accumulative error of Ah measurement method. The simulation results show that the proposed method has higher accuracy than the traditional Ah measurement method. |
