前言

本文件按照GB/T1.1—2020《标准化工作导则

第1部分：标准化文件的结构和起草规则》的规

定起草。

本文件修改采用IEC61982﹘4：2015《电动道路车辆用二次电池（除锂）第4部分：镍氢电池和

模块安全要求》。

本文件与IEC61982﹘4：2015相比做了下述结构调整：

—本文件的3.7对应IEC61982﹘4：2015的3.8。

本文件与IEC61982﹘4：2015的技术差异及其原因如下：

—更改了范围，将原文内容改为注（见第1章），以适用我国产品标准的表述方法；

—更改了术语和定义（见第3章），按照我国标准中的术语和定义进行修改，并删除了不适用本

文件的术语和定义；

—增加了GB/T19596—2017（见3.1），引用我国相关标准，以适用我国产品标准的表述方法；

—更改了IEC61982﹘4：2015的3.1（见3.1），采用GB/T19596—2017的定义，以适用于我国

产品标准的表述方法；

—更改了IEC61982﹘4：2015中3.4（见3.4），采用GB/T19596—2017的定义，以适用于我国

产品标准的表述方法；

—删除了IEC61982﹘4：2015中3.7，经技术差异对比建议删除该定义，同时将环境温度（25℃±

2℃）列入正文；

—更改了IEC61982﹘4：2015中3.8（见3.7），采用GB/T19596—2017中3.3.3.2.5荷电状态的术

语定义，以适用于我国产品标准的表述方法；

—更改了IEC61982﹘4：2015中4.2.1，将25℃±2K改为25℃±2℃，统一了单位符号；

—增加了方案B（见6.2.2），确保试验的准确性；

—增加了规范性引用文件GB38031—2020（见6.2.2.2），引用我国相关标准，完善试验方法；

—增加了方案B（见6.3.1、6.3.2、6.4.1、6.4.2），确保试验的准确性；

—更改了IEC61982﹘4：2015中6.4.2.2（见6.4.2.2），经技术差异对比建议删除“要求电池电压

达到3V”的内容，以适用于我国镍氢电池行业现状；

—增加了方案B（见6.4.3），确保试验的准确性；

—更改了IEC61982﹘4：2015中6.4.3.2（见6.4.3.2），经技术差异对比建议删除“要求电池电压

达到-3V”的内容，以适用于我国镍氢电池行业现状。

本文件做了下列编辑性改动：

—将标准名称更改为《电动道路车辆用镍氢电池和模块

安全要求》；

—删除了参考文献。
