IEC 62933-4-2:20 25定义了评估和报告电池储能系统（BESS）的累积子系统中的电芯、液流电池、电池或液流电池故障对环境造成的负面影响的要求。 BESS中使用的该范围内的电池根据其电解质类型进行分类。这些电解质类型是水性、非水性或固体。 BESS其他部件故障直接导致的环境影响不在本文件的范围内。

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.
