摘要(Abstract)：

以锂离子动力电池单体为研究对象,测量不同频段下电池单体的阻抗特性以表征电池特性,并采用电气模型进行全频段阻抗特性拟合,结合电池单体及BUSBAR阻抗特性,建立整个动力电池包的电气特性模型。电驱系统是汽车上主要的电磁干扰源,在研究分析电机特性及控制策略的基础上,建立包括电驱系统在内的动力电池系统电磁干扰模型。通过仿真获取动力电池系统直流母线上的总电流变化,并与实车测试结果进行对比验证。对研究动力电池系统自身的电磁干扰及其影响机理,正确及时地发现潜在电磁干扰问题并加以解决,提高电池包系统、整车性能及增强系统运行可靠性有着重要意义。

关键词(KeyWords)： 单体等效电路模型;动力电池系统;全频段阻抗特性;转矩电流比控制
