电能存储 (EES) 系统 第4-2部分：环境问题指南 评估电化学存储系统中电池故障对环境的影响

[中文适用范围]： 本部分 IEC 62933 规定了评估和报告由电池储能系统（BESS）的积累子系统中电池、流动电池、蓄电池或流动蓄电池的故障对环境造成的负面影响的要求。 本范围内用于BESS的电池根据其电解质的类型进行分类。这些电解质类型包括水性、非水性或固态。 由BESS其他组件的故障直接引起的环境影响不在本文件范围内。 [外文原描述]： IEC 62933-4-2:2025 defines the requirements for evaluating and reporting the negative impact on the environment caused by the failure of a cell, flow cell, battery or flow battery in the accumulation subsystem of a battery energy storage system (BESS). The batteries within this scope used in a BESS are classified according to the type of their electrolyte. These electrolyte types are aqueous, non-aqueous or solid. The environmental impacts directly caused by the failure of other components of the BESS are not within the scope of this document.
