铁路应用 机车车辆 辅助电源系统用电池 第3部分：铅酸电池

[中文适用范围]： 本部分IEC 62973建立了列车电气接口的框架，以及用于铁路车辆辅助电源系统的VRLA型铅酸电池的尺寸（如容量、电池数量，以满足要求的负载曲线）和操作，并补充了IEC 62973-1，除非另有规定。 本文件提供了所需电池资格测试程序和安全措施的指导和标准链接。 引用的铅酸电池规范性参考提供了适用于其资格的多个要求和测试。 在本文件中，已根据需要选择和调整了这些引用标准中最适当的条款，以反映这些电池作为铁路车辆辅助电源的预期用途。 电池系统的子组件（如容器、充电控制、温度探头、铭牌等）的电池特定要求根据需要在本文件中涵盖。 充电系统不在本文件的范围内。 [外文原描述]： IEC 62973-3:2024 establishes the framework for the selection and operation of lead acid batteries of the VRLA type for auxiliary power supply systems on rolling stock of railways and complements IEC 62973-1, unless otherwise specified. This document provides guidance and links to standards for the required battery qualification tests procedures and safety measures to be implemented. In this document, the most appropriate clauses of these cited standards have been selected and adapted as needed to reflect the intended use of these batteries as auxiliary power sources on rolling stock of railways. The battery-specific requirements for subcomponents of battery systems such as containers, charging controls, temperature probes, nameplates and similar are covered in this document as needed. Charging systems are excluded from the scope of this document.
