资料介绍

针对参数辨识问题,选用二阶RC等效电路建殳锂离子电池组模型,通过脉冲放电实验初步辨识模型的参数,进行多目标优化,确定最优参数。采用混合脉冲功率特性(HPPC)测试方法验证模型的精度。模型能准确地描述锂离子电池组的充放电特性,平均误差为0.05V,最大误差为0.25V,最大相对误差为2%,满足工程应用的精度要求。

Aiming at the parameter identification problem, the two order RC equivalent circuit was used to establish the Li-ion battery pack model. The parameters of the model were then preliminarily identified by pulse discharge experiment method. The multiobjective optimization of the parameters was carried out, the optimal parameters were determined. The accuracy of the model was verified by hybrid pulse power characterization(HPPC) test, the charge and discharge characteristics of the Li-ion battery pack could accurately describe by the Li-ion battery pack model. The average error was 0.05 V, the maximum error was 0.25 V and the maximum relative error was 2%, which could meet the accuracy requirements of engineering applications.
