汽车用直流母线薄膜电容器的基本资格 一般要求、测试条件和测试

[中文适用范围]： 本文件提供了用于验证包括定制直流链路薄膜电容器特性在内的要求、测试条件和测试方法，这些电容器用于汽车部件。根据其他IEC标准或AEC-Q200认证的标准直流链路电容器不在本文件范围内。本文件中列出的要求、测试条件和测试适用于为汽车电力电子设备开发的定制薄膜电容器，用于高压应用中的直流链路电容器或48V车载电气系统的中间电路。这些认证要求可以根据需要为技术创新设计的应用进行扩展或调整。补充内容和范围应在采购前由相关方协商确定并记录。汽车电力电子设备需要根据汽车制造商的环境认证标准进行测试。本文件中的测试不替代整车部件的组件要求规范中规定的测试或其中描述的其他或不同的进一步要求、测试条件和测试。本文件不包含验证电容器、电力电子设备和冷却系统之间热界面的测试。 [外文原描述]： IEC TS 63337:2024 provides requirements, test conditions and tests to validate characteristics including the service life of customized DC-link film capacitors for use in motor vehicle components. Standard DC-link capacitors qualified according to other IEC standards or AEC-Q200 are excluded from the scope of this document. The requirements, test conditions and tests listed in this document apply to customized film capacitors developed for use in motor vehicle power electronics for the application as a DC-link capacitor in HV applications or in the intermediate circuit of the 48 V on-board electrical system. These qualification requirements can be expanded or adapted for the application of technologically innovative designs, if necessary. The content and scope of supplements is therefore to be specified and documented in coordination between the responsible parties prior to sourcing. Power electronics in the motor vehicle need to be tested in accordance with the environmental qualification standards of the vehicle manufacturers. The tests in this document do not replace the tests specified in the Component Requirement Specifications for complete vehicle components or additional or deviating further requirements, test conditions and tests described therein. This document contains no tests to validate the thermal interface between capacitors, power electronics and the cooling system on the component level.
