1 Scope

This part of IEC 62933 applies to the effects of the environmental conditions on battery-based energy storage systems (BESS). This document addresses these effects and identifies causes, chains 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 on the entire BESS including all power and communication connections and their 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.
