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.
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.
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.
This work describes an improved risk assessment approach for analyzing safety designs in the battery energy storage system incorporated in large-scale solar to improve accident prevention and mitigation, via incorporating probabilistic event tree and systems theoretic analysis. The causal factors and mitigation measures are presented.
Considering that gas explosion may cause thermal runaway of battery module in the actual scene, the existence of high-temperature zone may be longer and the temperature peak may be higher. After the combustible gas got on fire, the gases volume expanded by high-temperature compresses the volume of the surrounding gases.
