动力锂电池安全国家标准GB/T 31485与IEC 62660-3的比较

Comparison of GB/T31485 and IEC 62660-3 on Traction Lithium-ion Battery Safety

对动力锂电池安全国家标准GB/T 31485-2015《电动汽车用动力蓄电池安全要求及试验方法》与国际标准IEC 62660-3:2016《电动道路车辆推进用二次锂离子电池第3部分:安全要求》的测试方法进行比较,讨论两种方法在检验项目、适用范围、试验条件及判定依据上的差异。GB/T 31485关注动力锂电池在使用、运输过程中安全性,IEC62660-3侧重考察动力锂电池在使用过程中安全性,并规定了更多的使用安全性试验项目。本文旨在为国内相关生产企业及检测机构提供参考。

Traction lithium-ion battery safety national standard GB/T 31485-2015 Safety requirement and test methods for traction battery of electric vehicle and IEC 62660-3：2016 Secondary lithium-ion cells for the propulsion of electric road vehicles - Part 3： Safety requirements were compared in test inspection items, scope of application, test conditions and judging basis. GB/T 31485 focuses on the safety of traction lithium-ion batteries in use and transportation. IEC 62660-3 focuses on the safety of traction lithium-ion batteries in the use process,and stipulating more safety test projects during use. Designed to provide reference for relevant domestic production companies and testing institutions.
