Explosion-proof windows of energy storage containers

Does a lithium-ion energy storage unit need explosion control?

To address the safety issues associated with lithium-ion energy storage, NFPA 855 and several other fire codes require any BESS the size of a small ISO container or larger to be provided with some form of explosion control. This includes walk-in units, cabinet style BESS and buildings.

How do you protect a battery energy storage system?

Three protection strategies include deploying explosion protection, suppression systems, and detection systems. 2. Explosion vent panels are installed on the top of battery energy storage system shipping containers to safely direct an explosion upward, away from people and property. Courtesy: Fike Corp. Explosion Protection.

What happens if a Bess container explodes?

“If a deflagration occurs within a BESS container, the explosion vents installed on the top of the enclosure will burst at a predefined low burst pressure, releasing the pressure and flames in a controlled way, thereby preventing an uncontrolled rupture of the vessel,” Stephens said.

Can explosion prevention systems mitigate gas concentrations according to NFPA 69 standards?

Simulations are often preferred to determine if an explosion prevention system can effectively mitigate gas concentrations according to NFPA 69 standards. CFD methodology can assist with the performance-based design of explosion prevention systems containing exhaust systems.

How do you protect a shipping container from exploding?

To protect against the worst-case scenario of the shipping container exploding, Fike recommends that all BESSs are protected with explosion vent panels (Figure 2).

Can CFD be used to design an explosion prevention system?

CFD methodology can be extended to design an explosion prevention system for any ESS enclosure. Results can also provide the controlled release rate of flammable and toxic materials which is useful information for first responders and to assess environmental impacts.
