FAQS about Household Battery Safety 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 are the standards for battery energy storage systems (Bess)?

As the industry for battery energy storage systems (BESS) has grown, a broad range of H&S related standards have been developed. There are national and international standards, those adopted by the British Standards Institution (BSI) or published by International Electrotechnical Commission (IEC), CENELEC, ISO, etc.

Are domestic battery energy storage systems a safety hazard?

Even though few incidents with domestic battery energy storage systems (BESSs) are known in the public domain, the use of large batteries in the domestic environment represents a safety hazard. This report undertakes a review of the technology and its application, in order to understand what further measures might be required to mitigate the risks.

What are the safety standards for a battery module?

A common battery safety standard that battery modules are tested to is IEC 62619. For the inverters, IEC 62109-1 and IEC 62109-2 are commonly used safety standards. Many systems have also been certified for the North American market according to standards such as UL 1973 (battery modules) and UL 1741 (inverter).
