摘　　要：针对传统铅酸动力电池参数辨识方法缺乏理论基础以及辨识误差较大的问题,提出了一种新的M序列作为激励的辨识方法。选取Thevenin模型作为铅酸动力电池等效电路模型,通过建模仿真分析了M序列在铅酸动力电池参数辨识中的可行性,并给出了M序列参数选取原则。确定了M序列作为辨识激励的合适参数,最后仿真得出了该方法辨识所得的铅酸动力电池相关参数值。与实验获得的电池真实参数值比较结果表明,采用M序列作为激励的参数辨识方法,能够准确有效地辨识铅酸动力电池等效电路模型的参数,并可以对其参数的获取提供理论基础与支持。Paper for problem of the traditional parameter identification method for lead-acid battery had recognition errors and lacked of the theoretical basis,a new identification method used M sequence as incentives is proposed,Thevenin model equivalent circuit model as the model of lead-acid battery is selected,the feasibility of M sequence in the parameter identification of lead-acid battery are analyzed through modeling and simulation,and the selected principle of the M sequence parameter are grven out,the appropriate parameters of the M sequence as incentives are determined.The identification parameter values of the lead-acid battery are obtained through the simulation at last.The comparison results between the true parameter values and the identification parameter values show that the identification method used the M sequence as the incentive could identification the equivalent circuit model parameters of lead-acid battery accurately and efficiently,and could provide the theoretical foundation and support for obtain the parameters of the equivalent circuit model.
