Cause of explosion in photovoltaic power station energy storage station

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.

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,

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.

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.

What are some causes of lithium-ion battery explosions?

Some of these batteries have experienced troubling fires and explosions due to deflagration pressure and gas burning velocity and high-voltage arc induced explosion pressures. Utility-scale lithium-ion energy storage batteries are being installed at an accelerating rate in many parts of the world.

What caused a lithium-ion energy storage system explosion in China?

The cause of a lithium-ion energy storage system explosion that killed two firemen in China earlier this year has proved inconclusive. A report by Beijing Fire Station noted that cell quality, battery management, electrical topology, external dust storms, and even wire arrangement could have led to the fire.
