用于电动道路车辆推进的次级锂离子电池 - 第2部分:可靠性和滥用测试

[中文适用范围]： IEC 62660 的这一部分规定了观察用于电动汽车（包括纯电动汽车 (BEV) 和混合动力电动汽车 (HEV)）驱动的二次锂离子电池和电池块的可靠性和滥用行为的测试程序。注 1：用于推进插电式混合动力电动汽车（PHEV）的二次锂离子电池可以根据电池制造商与电池制造商之间的协议，根据电池系统设计@，通过 BEV 应用或 HEV 应用@的程序进行测试。客户。本文件规定了用于动力电池和混合动力电动汽车的锂离子电池基本特性的标准测试程序和条件。这些测试对于获取用于各种电池系统和电池组设计的锂离子电池的可靠性和滥用行为的基本数据是必不可少的。本文件提供了用于电池系统或电池组设计的测试结果描述的标准分类。注 2：根据电池制造商和客户之间的协议，电池块可以用作电池的替代品。注3：电动汽车应用锂离子电池的安全要求在IEC 62660-3 [3]中定义。 [外文原描述]： IEC 62660-2:2018 specifies test procedures to observe the reliability and abuse behaviour of secondary lithium-ion cells and cell blocks used for propulsion of electric vehicles including battery electric vehicles (BEV) and hybrid electric vehicles (HEV). This document specifies the standard test procedures and conditions for basic characteristics of lithium-ion cells for use in propulsion of battery and hybrid electric vehicles. The tests are indispensable for obtaining essential data on reliability and abuse behaviour of lithium-ion cells for use in various designs of battery systems and battery packs. This document provides standard classification of description of test results to be used for the design of battery systems or battery packs. IEC 62660-2:2018 cancels and replaces the first edition published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) The procedure of forced discharge test has been clarified (6.4.3.2). b) "Cell block" has been added to the scope (Clause 1). c) Option of temperature cycling test with electrical operation has been deleted (6.3.2). d) The test conditions for overcharge test have been revised (6.4.2.2).
