scope:

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 .
