| 摘 要： | 根据目前动力蓄电池模型研究的现状,分析了各种电池模型的优缺点,提出了一种非线性的等效电路电池模型,并通过卡尔曼滤波算法,在线辨识电池内阻,得到内阻自适应电池模型.通过两种实验,分别在不同电流循环工况和环境温度下测试模型的适应性,结果表明,该模型可以较好地反映电池的动态特性,并能适应电流、荷电状态、温度等变化对电池的影响.

| Abstract: | Based on the present battery models,a novel non-linear battery model based on equivalent circuit was proposed.Furthermore,a method using Kalman filter to identify the inner resistance of the battery was studied which led to a resistance adaptive battery model.Two experiments,in which the battery underwent different current cycles and different temperatures,were implemented to test the battery model.Results show that the model proposed can describe the dynamic characteristics of the battery pack very well ev... |
