《便携式电子产品用锂离子电池和电池组安全要求》解析

Analysis on Safety Requirement for Lithium-ion Cells and Batteries Used in Portable Electronic Equipments

介绍了GB 31241-2014《便携式电子产品用锂离子电池和电池组安全要求》编制过程中参考的国际标准和国外标准,阐述了GB 31241的试验项目与IEC标准、UN标准和UL标准的异同,重点分析了GB 31241中的电池高温外部短路试验、电池强制放电试验、电池挤压试验、电池热滥用试验、电池组跌落试验、电池组过压充电试验的试验条件和试验方法,并比较了与IEC相关试验的差异。

The reference of GB 31241-2014 such as international standards and foreign standards is introduced. The difference between GB 31241 and IEC, UN, UL standards is analyzed. Some key tests such as high temperature external short circuit for cells, forced discharge for cells, crush for cells, thermal abuse for cells, drop for batteries, and overcharge for batteries are analyzed.
