IEC 62619检测项目

IEC62619于2017年2月13日发布，是储能电池的安全标准，属于自愿性认证。 IEC62619---《Secondarycellsandbatteriescontainingalkalineorothernon-acidelectrolytes–Safetyrequirementsforsecondarylithiumcellsandbatteries,foruseinindustrialapplications》 目前已认证厂家包括但不限于： 厂家：大连中比（大连比克）产品：电芯26650 厂家：中兴派能产品：储能系统 适用范围/产品 1、大容量工业用电池系统中的电芯、电池 2、固定式：UPS、紧急电源装置、电力储备及相同用途的装置 3、移动式：高尔夫球车、叉车、无人搬运车、铁路及海洋运输 认证模式：型式测试---审厂---发证 测试 IEC62619侧重于储能电池和电池系统的安全要求，不仅对电芯和电池模块进行外部短路、撞击、跌落、热滥用、过充、强制放电等安全测试，而且对电池管理系统（BMS）进行过充电压保护、过充电流保护、过热保护、耐热失控蔓延等功能进行评估。 8.2Reasonablyforeseeablemisuse 试验项目 Externalshortcircuittest(cellorcellblock) 章节号 标准要求 8.2.1 Fullychargedcellsarestoredinanambienttemperatureof25°C±5°C.Eachcellisthenshortcircuitedbyconnectingthepositiveandnegativeterminalswithatotalexternalresistanceof30+/-10mΩ.
