_202412 锂离子电池模块性能等级

[中文适用范围]： 本文件为LIBM（锂离子电池模块）提供了推荐的电气性能测试指南，构成xEV（纯电动汽车和混合动力汽车）电池包系统的一部分。该测试指南也可用于其他应用，如固定式、船舶和飞机。但用户需自行决定是否适用于其他应用。 本文件用户可能还对电池单元和/或电池包进行测试感兴趣。为避免在电池单元、模块和包之间进行可能冗余的测试，本文件未规定需进行的测试。用户应根据单个模块应用自行决定需进行的测试。本文件描述了如何进行每项测试。 本文件提供了一系列测试矩阵，可根据应用需求选择，以标准化其特定应用需求的测试程序。本文件中的测试性能值可用于比较、确认等目的。但合格/不合格标准不包含在本文件中。客户和供应商需自行确定合格/不合格标准。如果测量值用于确定电池模块额定值，测试模块应具有代表性。 LIBM由多个电池单元以不同串并联配置组成，通常表示为“XXP XXS”。功能齐全的LIBM应具有电池监测系统，以正确控制和监测单个电池电压和模块温度。LIBM配置应考虑电池压缩、固定、热传递、电气隔离和固定方法。 [外文原描述]： This document provides a recommended electrical performance testing guideline for LIBM, which makes up an xEV (Battery Electric Vehicles and Hybrid Electric Vehicles) battery pack system. This testing guideline may also be used for other applications, such as stationary, vessel, and aircraft. However, using the guideline for other applications should be determined by the users of this document. Users of this document may also be interested in conducting tests on battery cells and/or battery packs. To avoid conducting potentially redundant tests between cells, modules, and packs, this document does not specify which tests need to be conducted. Determination of which tests need to be conducted is at the user’s discretion and should be based on individual module applications. Rather than specifying which tests need to be conducted, this document describes how each test is to be conducted. This document provides a matrix of tests that can be selectively picked for the application requirements in order to standardize testing procedures for their specific application needs. Performance values from the tests in this document can be for comparative purposes, confirmation, and other reasons. However, pass/fail criteria are not part of this document. It is up to the customer and supplier to determine what the pass/fail criteria are. If the measured value is to be used to determine battery module ratings, the tested modules should be representative of those to be manufactured. LIBM consists of multiple cells grouped and electrically interconnected in various series and parallel configurations - typically noted as “XXP XXS.” Fully functional LIBM shall have a battery monitoring system to allow for the proper control and operation of individual cell voltage and module temperature monitoring. The LIBM configuration shall accommodate for cell compression, retention, thermal heat transferal, electrical isolation, and a hold-down method.
