Abstract: With the development of electric vehicle (EV), the estimation of battery state of charge (SOC) has attracted more and more attention. Accurate estimation of state of charge is very important for the energy management of electric vehicles. However, the accuracy of estimation has become the bottleneck of its development. Based on the analysis of impedance spectrum, a simplified impedance model of battery is derived by using constant phase element (CPE). By introducing EKF, a battery test platform is established, through the fusion with the EKF algorithm on the impedance model to estimate the SOC of lithium-ion battery accurately. The results of simulation and dynamic state test show that compared with other models and EKF algorithm, the SOC estimation method proposed has good performances in convergence and robustness, which could control the error within ±1%.

Key words: lithium-ion battery, electric vehicles, estimation of SOC, impedance model, extended Kalman filtering
