IEC 63057:2020规定了永久安装在非推进用途道路车辆中的二次锂电池的安全测试和要求。本文件涵盖永久安装在不用于推进的道路车辆中的替换二次电池。 以下是利用本文件范围内的电池的典型应用:用于启动内燃机、照明、车载辅助设备和用于制动再生的能量吸收的动力源。 本文件适用于最大电压小于或等于60 V DC的电池。 主要用于电动汽车（EV）推进的电池，包括电池电动汽车（BEV）、混合动力电动汽车（HEV）和插电式混合动力电动汽车（PHEV）不在本文件范围内。

IEC 63057:2020 specifies safety tests and requirements for secondary lithium batteries permanently installed in road vehicles not for the propulsion. Replacement secondary batteries permanently installed in road vehicles not for propulsion are covered by this document.
The following are typical applications that utilize the batteries under the scope of this document: a power source for the starting of internal combustion engines, lighting, on-board auxiliary equipment, and energy absorption for regeneration from braking.
This document applies to batteries with a maximum voltage less than or equal to 60 V DC.
The batteries primarily used for propulsion of electric vehicles (EVs), including battery electric vehicles (BEVs), hybrid electric vehicles (HEVs), and plug-in hybrid electric vehicles (PHEVs) are not covered by this document.
