Are batteries a fire hazard?

To minimise the risk of batteries becoming a fire hazard, a new British Standard covering fire safety for home battery storage installations came into force on 31 March 2024. The standard is – PAS 63100:2024: Electrical installations. Protection against fire of battery energy storage systems (BESS) for use in dwellings.

What are the requirements for a battery energy storage enclosure?

The edges of the ventilation must be at least 1 metre from the edges of: Furthermore, any ventilation for the location must not compromise the fire resistance of the enclosure. PAS 63100-2024 represents a significant advancement in ensuring the safe and efficient operation of battery energy storage systems (BESS) in the UK.

What makes a battery energy storage system safe and efficient?

Safe and efficient operation of a battery energy storage system (BESS) hinges on correct electrical installation. To prevent electrical hazards and ensure longevity, strict adherence to guidelines is essential.

Can home energy storage batteries catch fire?

It should be noted that fires from domestic home energy storage batteries are extremely rare. Most Home energy batteries use Lithium Iron Phosphate technology (LiFePO4). Whilst this technology makes for a heavier battery, it is known to be very safe and does not catch fire under any normal circumstances.

Does a battery energy storage system need ventilation?

PAS 63100-2024 states that indoor locations for battery energy storage systems (BESS) must have fresh air ventilation to outdoors. The edges of the ventilation must be at least 1 metre from the edges of: Furthermore, any ventilation for the location must not compromise the fire resistance of the enclosure.

What is a battery energy storage system?

Battery energy storage systems (BESS), also known as Electrical Energy (Battery) Storage systems or solar batteries, are becoming increasingly popular for residential units with PV solar installations, and (although much less frequently) small wind-turbines¹.
