Over a recent 18-month period ending in early 2020, over two dozen large-scale battery energy storage sites around the world had experienced failures that resulted in destructive fires. In total, more than 180 MWh were involved in the fires.
The probabilities of each occurrence for fire hazard are then calculated based on Pr(Outcome 1 |fire) = = P r (B 1) ∙ P r (B 2 | B 1) ∙ P r (B 3 | B 1 ∩ B 2). The frequency of fire event are therefore calculated as λ ∙ Pr B 1 ∩ B 2 ∩ B 3 .

Probability results of the mainline nodes under forward inference. Regarding the human casualties and property damage as consequences of a fire accident in a warehouse, the probabilities of “3–10 people” casualties and property damage of “Greater than 50 million RMB” were 0.72 % and 2.07 %, respectively.
The main objective was to analyze the evolution and consequences of LIB warehouse fires dynamically and provide effective suggestions for fire risk reduction. The results showed that the proposed framework was a reliable avenue for fire risk assessment of LIB warehouses.
Besides, the sensitivity analysis results showed that the battery SOC and automatic sprinklers have a greater impact on the fire spreading in a warehouse. Where the battery SOC sensitivity was the greatest, with the increase in the SOC value, the probability of large-scale fire spreading increased from 40.3 % to 95.2 %.
Conclusions The LIB warehouse fires develop rapidly and are highly susceptible to loss of control, thus potentially resulting in substantial human casualties and economic losses. There has been a shortage of research on the fire risk assessment considering the causes of the thermal runaway in LIBs.
The effectiveness of firefighting methods is crucial to lithium-ion battery warehouse fires. There are two types of firefighting methods in this model, one is the node M18 (i.e., manual firefighting), which extinguishes fires at the early stage of battery fires and can nip them in the bud to prevent the expansion and spread of fires.
Cotton warehouse fire probability is much greater than the probability of lithium-ion battery fire, but after firefighting measures, the probability of fire remains unextinguished will be lower than the lithium-ion battery warehouse 2.88 %.
