BS EN IEC 62933-4-3:2025

This standard BS EN IEC 62933-4-3:2025 Electrical energy storage(EES) systems is classified in these ICS categories:

• 13.020.30 Environmental impact assessment
• 27.010 Energy and heat transfer engineering in general

IEC 62933-4-3:2025 applies to the effects of the environmental conditions on Battery Energy Storage Systems (BESS). This document addresses these effects and identifies causes, chain of events and final effects on the BESS. Based on those effects, preventative or mitigating measures are described. Typical environmental effects on the BESS include, but are not limited to, the effects of lightning, seismic activities, water, air, flora, fauna, and humans. The described measures focus as a guideline on the entire BESS including all power and communication connections and its Point of Connections (POCs). The scope of this document is limited to BESS specific requirements and operating conditions. Specific design or safety requirements of individual BESS subsystems are excluded from this document.
