International Standards for BESS Safety and Risk Assessment

This document outlines international standards for electrical, electronic, and related technologies, focusing on battery energy storage systems (BESS). It covers risk assessment, subsystem design, fire protection measures, and safety protocols. Key aspects include the need for lockable isolating devices, fire-protecting doors, and ventilation for gas venting. Staff training is emphasized for safe operation and maintenance. The document details protection against chemical effects, over-charging, and short-circuits, with acceptance criteria for voltage and current ranges. It also addresses hazards such as thermal runaway, flammable fluids, and physical risks, recommending adherence to international standards for fire propagation testing and system response verification. The standard applies to various BESS applications, ensuring safety across utility grid integration, maintenance, and emergency situations.
