摘　　要：针对储能系统中电池管理系统中SOC(电池荷电状态)估算不准确问题,提出一种基于改进EKF算法的SOC估算方法。通过Matlab/Simulink仿真验证表明该算法能够实现SoC初始值快速收敛,有效解决SoC初始值不准确和累积误差问题。Aiming at the problem of inaccurate Soc(state-of-charge)estimation in the battery management system of energy storage systems,a SoC estimation method based on improved EKF algorithm was proposed.Matlab/Simulink simulation shows that this algorithm can realize rapid convergence of soc initial values and effectively solve the problems of inaccurate SOC initial values and cumulative errors.
