摘　　要：动力电池系统是新能源电动汽车的核心部件,抗振动特性是动力电池系统的重要考察指标。本文以电池系统的振动试验为研究对象,介绍了振动试验的基本理论,对国内外动力电池系统标准中的振动试验方法和要求做了对比研究,并参考国标GB38031,对一款电动乘用车用电池包进行了振动试验,最后对振试验的方法和失效形式做了分析和总结。The resistance characteristic to vibration is the important indicator of power battery system, which is the core part of the new energy electric vehicle. Based on vibration test of battery system as the research object, this paper introduces the basic theory of vibration test, makes a comparative study to vibration test methods and requirements of domestic and foreign power battery test standards. And referring to the national standard GB38031, the vibration test of battery pack for an electric passenger car is carried out. Finally, the methods and failure forms of vibration test are analyzed and summarized.
