The latest version of domestic energy storage battery standards

What are the international standards for battery energy storage systems?

Appendix 1 includes a summary of applicable international standards for domestic battery energy storage systems (BESSs). When a standard exists as a British standard (BS) based on a European (EN or HD) standard, the BS version is referenced. The standards are divided into the following categories: Safety standards for electrical installations.

What is a domestic battery energy storage system (BESS)?

A domestic battery energy storage system (BESS) will be part of the electrical installation in residential buildings. Examples of standards that cover electrical installations in residential buildings are shown in Table A 2. The HD 60364 series is a harmonization document from CENELEC.

Are domestic battery energy storage systems safe?

However, even though few incidents with domestic battery energy storage systems (BESSs) are known in the public domain, questions have been raised regarding the safety of these systems. The concern is based on the large energy content within these systems.

Are battery energy storage systems protected against fire?

Protection against fire of battery energy storage systems (BESS) for use in dwellings came into practice on 31 March 2024. The standard identifies new requirements relating to the installation of electrical battery storage systems (BESS) in houses using stationary secondary batteries as the medium for energy storage.

Are domestic lithium-ion battery storage systems safe?

Several standards that will be applicable for domestic lithium-ion battery storage are currently under development or have recently been published. The first edition of IEC 62933-5-2, which has recently been published, covers the safety of domestic energy storage systems.

What is the scope of energy storage system standards?

The scope of the energy storage system standards includes both industrial large-scale energy storage systems as well as domestic energy storage systems. Appendix 1 includes a summary of applicable international standards for domestic battery energy storage systems (BESSs).
