摘要/Abstract

摘要： 本项目以纯电动汽车锂离子动力电池集总参数RC等效电路模型为研究对象，在传统模型基础上，考虑了电池的极化效应特性和迟滞电压特性，创建一种新的锂离子动力电池动态等效电路模型；基于实验测试，对该模型参数进行了辨识，并通过实验分析验证，该模型的估算误差为2%，比传统一阶及二阶模型准确，比三阶RC模型简单。

关键词: 极化效应, 迟滞电压, 等效电路模型

Abstract: This article studied the RC equivalent circuit model of lumped parameters for lithium-ion batteries in electric vehicles. On the base of the traditional battery models, this research creates a new dynamic equivalent circuit model of lithium-ion power battery considering the polarization effect and hysteresis voltage characteristics of battery. Model's parameters were identified by tests. The estimated error of this model is 2% through experimental analysis, which is more accurate than the traditional first-order and second-order models and simpler than the third-order RC model.

Key words: polarization effect, hysteresis voltage, equivalent circuit model
