IEC 62973-1:20 18适用于机车车辆（如轻轨车辆、有轨电车、有轨电车、地铁、通勤列车、区域列车、高速列车、机车等）上使用的辅助供电系统的各种可充电电池技术。）. 本文件侧重于: -以下电池标称电压的电气接口的描述:24V、32V、36V、48V、64V、72V、87V、96V、110V； -电气接口的描述:考虑电池负载曲线和电池容量尺寸参数（例如，工作电压范围和充电特性）。 本文件的主要目的是通过考虑各种电池参数来实现电气接口的标准化，以便计算标准其他部分中详述的各种电池技术的特定负载曲线所需的电池容量。

IEC 62973-1:2018 applies to various rechargeable battery technologies for auxiliary power supply systems used on rolling stock (e.g. light rail vehicles, tramways, streetcars, metros, commuter trains, regional trains, high speed trains, locomotives, etc.).
This document focuses on:
- the description of electrical interfaces for the following battery nominal voltages: 24 V, 32 V, 36 V, 48 V, 64 V, 72 V, 87 V, 96 V, 110 V;
- the description of electrical interfaces: considering battery load profile and battery capacity sizing parameters (e.g. operating voltage range and charging characteristics).
The main objective of this document is to achieve standardization of the electrical interfaces by considering various battery parameters in order to allow for calculating the battery capacity required for a specific load profile for the various battery technologies as detailed in the other parts of the standard.
