蓄电池在充放电过程中，其内部存在着复杂的电化学反应，导致蓄电池荷电状态（S O C）及各个参数是多维、非线性的关系。因此，本文基于7-HK-182型铅酸蓄电池建立等效电路模型，进行参数辨识。在此基础上，采用扩展卡尔曼滤波（EKF）算法，利用 Matlab软件对蓄电池SOC及各个参数进行实时仿真，通过仿真与实验结果对比验证了 EKF算法的实时性与准确性。

In the process of charging and discharging of the battery, there is a complex internal electrochemical reaction, which is resulting in the state of charge of the battery and the various parameters that are multidimensional nonlinear relationships. Thus, this paper builds the equivalent circuit model which is based on 7-HK-182 lead-acid battery to identify the parameters. On this basis, by using extended Kalman iflter (EKF) algorithm and Matlab software real-time simulation on various parameters of SOC of the battery, we verify the real-time and accuracy of EKF algorithm through comparing the simulation with experimental results.
