ident occurred in the lithium battery energy storage system of a power station in Shanxi province, China. According to the investigation report, it is determined that the cause of the fire accident of the energy storage system is the excessive voltage and current caused by the surge eff
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,
It can be seen that in the early stage of the explosion, due to the existence of battery containers on both sides, the flame spread to the surrounding unburned area in a form of cylinder. Moreover, it can be seen from YZ profile that the upward development of combustion rate was more prominent.
Unfortunately, a small but significant fraction of these systems has experienced field failures resulting in both fires and explosions. A comprehensive review of these issues has been published in the EPRI Battery Storage Fire Safety Roadmap (report 3002022540 ), highlighting the need for specific eforts around explosion hazard mitigation.
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 LiFePO 4 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.
Variation process of combustion rate in energy storage container during explosion. Due to the numerous battery modules installed in the container, the flame was limited in the middle aisle and on the top of the container. Fig. 7 a showed the combustion rate distribution at 0.24 second.
