Significance of the explosion of the high-tech energy storage station

Do container type lithium-ion battery energy storage stations cause gas explosions?

Here, experimental and numerical studies on the gas explosion hazards of container type lithium-ion battery energy storage station are carried out. In the experiment, the LiFePO4 battery module of 8.8kWh was overcharged to thermal runaway in a real energy storage container, and the combustible gases were ignited to trigger an explosion.

What caused the explosion at the power station?

The sudden explosion of the power station in the north area could be explained by the safety accident induction mechanism of lithium batteries. This mechanism involves the thermal failure of the batteries under extreme conditions when they are significantly affected by internal and external sources.

What happened to the energy storage system?

The energy storage system was installed and put into operation in 2018, with a photovoltaic power generation capacity of 3.4MW and a storage capacity of 10MWh. The explosion destroyed 0.5MW of energy storage batteries. It is understood that the lithium-ion battery cell supplier of the energy storage station is LG New Energy.

What are the characteristics of fire and explosion of energy storage stations?

And the fire and explosion of energy storage stations have certain characteristics, mainly including: the types of accident batteries are mostly ternary lithium-ion batteries, and most of them occur during charging and rest periods.

Are there fires and explosions in lithium battery energy storage stations?

There have also been considerable reports of fires and explosions in lithium battery energy storage stations. According to incomplete statistics, there have been over 30 incidents of fire and explosion at energy storage plants worldwide in the past 10 years.

Why is the energy storage power station a fire hazard?

ng to effectively detect flammable gases, and failing to make timely warnings, resulting in an explosion. The large fire spread of the energy storage power station indicates that the on-site firefighting system failed to control the fire in the first time, and the hand-held fire extinguishing device installed on the site cannot functionate,
