Case study of battery incident at energy storage station

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.

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 causes large-scale lithium-ion energy storage battery fires?

Several large-scale lithium-ion energy storage battery fire incidents have involved explosions. The large explosion incidents are due to the deflagration of accumulated flammable gases generated during cell thermal runaways within one or more modules. This leads to damage of battery system enclosures.

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.

Are utility-scale lithium-ion energy storage batteries dangerous?

Utility-scale lithium-ion energy storage batteries are being installed at an accelerating rate in many parts of the world. Some of these batteries have experienced troubling fires and explosions.

Does the battery energy storage industry use system analysis?

In view of the analysis of the complexity of socio-technical systems, there are few cases in which the battery energy storage industry uses system analysis methods to carry out cause analysis. Therefore, based on the STAMP model, the thermal runaway diffusion explosion accident of the BESS was systematically analyzed.
