摘要:
针对常用的等效电路模型参数辨识软件在使用时需用户多次手动调整初始参数，不利于阻抗谱车载应用的问题，提出了一种无干预的等效电路模型参数辨识方法。根据电化学阻抗谱各特征成分与等效电路模型不同电路环节相对应的规律，通过分段拟合的方法自适应地获取阻抗谱拟合的初值，进而实现了等效电路模型参数辨识。通过解析不同老化状态、荷电状态、温度下的阻抗谱，发现该方法与常用参数辨识软件的结果保持一致，从而为阻抗谱在线应用提供了基础。
Abstract:
Aiming at the disadvantage that the commonly used equivalent circuit model parameter identification software requires the user to manually adjust the initial parameters many times during use, which is not conducive to the on-board application of impedance spectroscopy, a non-interventional equivalent circuit model parameter identification method is proposed. According to the law that each characteristic component of electrochemical impedance spectroscopy corresponds to the different circuit links of the equivalent circuit model, the initial value of impedance spectroscopy fitting is adaptively obtained through the method of segmented fitting, and then the parameter identification of the equivalent circuit model is realized. By analyzing impedance spectra under different SOH, SOC, and temperatures, it is found that this method is consistent with the results of commonly used parameter identification software, which provides a basis for online impedance spectroscopy applications.
