A variable capacitor component was established using Simscape language,then the constant charge-discharge experiments were conducted to obtain experimental data for the identification of the model parameters in Simulink.By comparison of the experimental data and the simulation data,the error is small.Compared with other modeling approaches,the method presented in this paper shows that the modeling period is shorted and the precision is improved.%采用 Simscape 建立了超级电容等效电路模型中的可变电容模型，并使用恒流充放电试验进行了模型参数辨识。试验数据和仿真数据相比，模型的误差较小。与其他的超级电容模型参数辨识方法相比较，所提供的方法缩短了建模周期、提高了模型精度。
