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: \u2013 electricity, \u2013 short-circuits, \u2013 electrolyte, \u2013 gas emission, \u2013 fire, \u2013 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.<\/p>\n
