Energy storage rack fire protection

Can a lithium-ion battery energy storage system detect a fire?

Since December 2019, Siemens has been offering a VdS-certified fire detection concept for stationary lithium-ion battery energy storage systems.* Through Siemens research with multiple lithium-ion battery manufacturers, the FDA unit has proven to detect a pending battery fire event up to 5 times faster than competitive detection technologies.

How does a fire protection system work?

In addition to controlling the automated extinguishing system, the fire protection system triggers all other necessary battery management system control functions. As its name implies – "aspirated" smoke and off-gas detection systems use an "aspirator" mounted in a detector unit.

Are Lib-ESS batteries a fire protection system?

LIB-ESSs contain a large quantity of batteries and have high energy density. Understanding the burning behavior of these systems is critical to proper fire protection system design. To facilitate this effort, a series of small- to large-scale fire tests were conducted using ESS comprised of either LFP or LNO/LMO batteries.

What is an energy storage system (ESS) enclosure?

An energy storage system (ESS) enclosure typically comprises multiple racks, each containing several modules (Figure 1). These modules consist of numerous lithium-ion (Li-ion) cells, which function as rechargeable batteries designed to store and discharge electrical energy.

What is the NFPA 855 standard for stationary energy storage systems?

Setting up minimum separation from walls, openings, and other structural elements. The National Fire Protection Association NFPA 855 Standard for the Installation of Stationary Energy Storage Systems provides the minimum requirements for mitigating hazards associated with ESS of diferent battery types.

What is energy storage & how does it work?

As the use of these variable sources of energy grows – so does the use of energy storage systems. Energy storage is a key component in balancing out supply and demand fluctuations. Today, lithium-ion battery energy storage systems (BESS) have proven to be the most effective type and, as a result, installations are growing fast.
