Working principle of energy storage cabinet fire protection system

What if DS 533 capacity exceeds 20 kWh per rack?

If the capacity exceeds 20 kWh per rack, DS 5-33, Energy Storage Systems is to be followed. Table 4 summarizes the key fire protection guidelines of Data Sheets 5-32 and 5-33 with respect to sprinkler protection and physical separation and/or barriers between equipment with Li-ion batteries.

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 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.

Should a fire module/cabinet contain water?

Water has superior cooling capacity, is plentiful (in many areas), and is easy to transport to the seat of the fire. While water might be the agent of choice, the module/cabinet configuration could make penetration of water dificult for cooling the area of origin but might still be efective for containment.
