Can a mechanical exhaust ventilation system prevent explosions in Li-ion-based stationary battery energy storage systems?

This work developed a performance-based methodology to design a mechanical exhaust ventilation system for explosion prevention in Li-Ion-based stationary battery energy storage systems (BESS).

Can a CFD-based method be used to design an explosion prevention system?

Note that the work presented here did not consider the presence of a clean agent or an aerosol-based suppression system that may impact the performance of the detection system and the ventilation system. In general, a CFD-based methodology can be effectively used with the performance-based design of an explosion prevention system.

How can CFD be used in explosion prevention systems containing exhaust systems?

CFD methodology can assist with the performance-based design of explosion prevention systems containing exhaust systems. CFD is a simulation tool that produces predictions of fluid-flow phenomena based on the laws governing fluid motion (i.e., mass, momentum, and energy).

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.

Can explosion prevention system remove battery gas from the enclosure?

The evolution of battery gas in Fig. 13, Fig. 14 shows that the explosion prevention system can remove the battery gas from the enclosure. The 3D contours of battery gas can also help identify local spots where battery gas can concentrate.

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.
