电气能量存储（EES）系统 第5-2部分：与电网集成的EES系统的安全要求 基于电化学的系统

[中文适用范围]： IEC 62933-5-2:2025 主要描述了电网连接型储能系统在使用电化学储能子系统时对人员的安全方面，以及在适当情况下对周围环境和生物的安全事项。本文件适用于电池储能系统（BESS）的整个生命周期（从设计到使用寿命结束的管理）。本文件提供了由于使用电化学储能子系统（如电池系统）而产生的额外安全规定，这些规定超出了IEC 62933-5-1中所描述的一般安全考虑范围。本文件规定了“电化学”储能系统作为“系统”的安全要求，以减少由于子系统之间相互作用所导致的电化学储能系统危害所带来的伤害或损害风险。 [外文原描述]： IEC 62933-5-2:2025 primarily describes safety aspects for people and, where appropriate, safety matters related to the surroundings and living beings for grid-connected energy storage systems where an electrochemical storage subsystem is used. This document is applicable to the entire life cycle of BESS (from design to end of service life management). This document provides further safety provisions that arise due to the use of an electrochemical storage subsystem (e.g. battery system) in EES systems that are beyond the general safety considerations described in IEC 62933-5-1. This document specifies the safety requirements of an "electrochemical" energy storage system as a "system" to reduce the risk of harm or damage caused by the hazards of an electrochemical energy storage system due to interactions between the subsystems as presently understood.
