Safety requirements for secondary batteries and battery installations - Part 5: Safe operation of stationary lithium ion batteries

IEC 62485-5:2020 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.
