UNE-EN IEC 62485-5:2021

This part of the IEC 62485 applies to the installation of one or more stationary secondary batteries having a maximum aggregate voltage of d.c. 1500 V (nominal) to any d.c. part of the power network and describes the principal measures for protections during normal operation or those that can be expected under fault conditions against hazards generated from:

electricity,

short circuits,

electrolyte,

gas emission,

fire,

explosion.

This International Standard provides requirements on safety aspects associated with the installation, use, inspection, and maintenance of lithium-ion batteries used in stationary application.

This standard covers industrial applications in separate closed Buildings/housings as well as in public buildings, offices and private residential / homes, maintenance and disposal of lithium-ion batteries used in stationary applications. Battery energy storage system (BESS) is an application.

Batteries containing lithium metal are not covered by this standard.

Examples for the main applications are:

telecommunications,

power station operation,

central emergency lighting and alarm systems,

uninterruptible power supplies, (UPS)

stationary engine starting,

photovoltaic systems .
