2阶RC电池模型.动力锂离子电池二阶等效电路模型（MATLAB/simulink环境下运行）(lithium_cell_2RC.Lithium-ion battery second-order equivalent circuit model (running MATLAB/under simulink environment))

该Simulink仿真模型基于锂电池的二阶RC模型，采用扩展卡尔曼滤波算法实现锂电池的SOC估计。(The Simulink simulation model is based on the second-order RC model of lithium batteries, and the extended Kalman filter algorithm is used to estimate the SOC of lithium batteries.)
