Container energy storage fire fighting

What is a stationary energy storage system (ESS)?

Stationary Energy Storage Systems (ESS) are available in numerous designs. Beginning with small units for individual purposes with only small capacities, there are likewise large ESS parks with capacities up to several MWh (see Figure 1).

Can a sprinkler system fight a battery fire?

As already stated, the SUVEREN (I+II) fire tests showed that water is particularly suitable for fighting battery fires due to its extraordinary cooling effect. Conventional sprinkler systems use large amounts of water, which can cause greater damage to the electrics and electronics of the ESS.

How can a high pressure Watermist prevent a battery fire?

The gas concentrations measured during the tests demonstrated that smoke extraction, for example by Explosion Prevention Openings (EPO), is essential to minimize the explosion risk. The high-pressure watermist system suppressed the battery fire successfully even with fully opened EPOs.

Why is a battery a fire hazard?

Batteries combine highly flammable materials with high energy contents, which creates new hazards for the field of fire protection . The risk of a battery’s ignition, due to internal or external reasons, depends on various factors, such as state of charge (SOC), age or chemistry meaning the cathode material.
