Explosion-proof energy storage power station

Can a lithium ion battery cause a gas explosion in energy storage station?

The numerical study on gas explosion of energy storage station are carried out. Lithium-ion battery is widely used in the field of energy storage currently. However, the combustible gases produced by the batteries during thermal runaway process may lead to explosions in energy storage station.

Why are explosion hazards a concern for ESS batteries?

For grid-scale and residential applications of ESS, explosion hazards are a significant concern due to the propensity of lithium-ion batteries to undergo thermal runaway, which causes a release of flammable gases composed of hydrogen, hydrocarbons (e.g. methane, ethylene, etc.), carbon monoxide, and carbon dioxide.

Do explosion power and mass affect Li-Bess vent panels?

To investigate the effect of explosion power and mass on Li-BESS vent panels, the experiment tested the venting efficiency of standard vent panel at four different hydrogen concentrations. Then, four different unit area mass vent devices were tested under 19 % hydrogen concentration. 4.1. Effect of explosion power

Do explosion vent panels reduce explosion overpressure?

With the increasing utilization of explosion vent panels for gas explosion protection, relevant research has begun to emerge. Bauwens conducted experiments on venting hydrogen concentrations ranging from 12 % to 19 % in a rectangular space, analyzing the relationship between venting area and reduced explosion overpressure .

Do lithium-ion batteries cause explosions?

Lithium-ion batteries are widely used in the field of energy storage. However, the combustible gases generated during thermal runaway events of batteries may lead to explosion. The latest NFPA 855–2023 requires that lithium-ion energy storage stations (Li-BESS) larger than 20 kWh must install explosion protection devices.

Do lithium-ion energy storage stations need a vent panel?

The latest NFPA 855–2023 requires that lithium-ion energy storage stations (Li-BESS) larger than 20 kWh must install explosion protection devices. The vent panel is the preferred protection device for Li-BESS. In this study, the motion equation of the vent panel was derived.
