本文件规定了用于大功率或高能应用的电池组和系统的性能、可靠性和电气功能基本特征的测试程序。除非另有说明，否则本试验适用于两种应用。 注1:大功率电池组和系统的典型应用是混合动力电动汽车（HEV）和某些类型的燃料电池汽车（FCV）。 注2:高能电池组和系统的典型应用是电池电动汽车（BEV），插头- 在混合动力电动汽车（PHEV）和某些类型的燃料电池汽车（FCV）中。 注3:IEC 62660系列中规定了电池级测试。

This document specifies test procedures for the basic characteristics of performance, reliability and electrical functionality for the battery packs and systems for either high-power or high-energy application. Unless otherwise stated, the test applies to both applications. NOTE 1 Typical applications for high-power battery packs and systems are hybrid electric vehicles (HEVs) and some type of fuel cell vehicles (FCVs). NOTE 2 Typical applications for high-energy battery packs and systems are battery electric vehicles (BEVs), plug-in hybrid electric vehicles (PHEVs) and some type of fuel cell vehicles (FCVs). NOTE 3 Testing on cell level is specified in IEC 62660 series.
