Safety requirements for secondary batteries and battery installations - Part 5: Safe operation of stationary lithium ion batteries (IEC 62485-5:2020)

This part of IEC 62485 applies to the installation of one or more stationary secondary batteries having a maximum aggregate DC voltage of 1 500 V to any DC part of the power network, and describes the principal measures for protections during normal operation or under expected fault conditions against hazards generated from: – electricity, – short-circuits, – electrolyte, – gas emission, – fire, – explosion.This document provides requirements on safety aspects associated with the installation, use, inspection, and maintenance and disposal of lithium ion batteries used in stationary applications. This document covers stationary batteries for industrial applications that are installed in separate closed buildings or housings as well as stationary batteries that are installed in public buildings, offices and private residences. This document also covers the maintenance and disposal of lithium ion batteries used in stationary applications. Batteries containing lithium metal are not covered by this document. Examples of the main applications are: – telecommunications, – power station operation, – central emergency lighting and alarm systems, – uninterruptible power supplies (UPS), – stationary engine starting, – photovoltaic systems.
