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 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.

Why should a fire enclosure have a deflagration vent?

To enhance safety, enclosures should be equipped with vents to facilitate gas release and prevent accumulation. Since deflagration can occur even in the presence of fire suppression systems, the installation of deflagration vents at the top of the enclosure, compliant with NFPA 68, can help mitigate the risk of enclosure rupture during such events.

What is a Li-ion battery energy storage system?

Executive summary Li-ion battery Energy Storage Systems (ESS) are quickly becoming the most common type of electrochemical energy store for land and marine applications, and the use of the technology is continuously expanding.

How do you protect a battery module from a fire?

The most practical protection option is usually an external, fixed firefighting system. A fixed firefighting system does not stop an already occurring thermal runaway sequence within a battery module, but it can prevent fire spread from module to module, or from pack to pack, or to adjacent combustibles within the space.

Can a fire propagate to another unit?

For acceptable performance, the fire involving one module or pack shall not propagate to an adjacent unit, and the fire during the test shall be contained within the room or enclosed area for a duration equal to the fire resistance rating of the room separation.
