Research on thermal runaway of pouch battery under mechanical abuse
Using a commercially pouch battery as the object,the most rigorous test-nail test was carried out to study the thermal propagation behavior at the module level.The results showed that the battery heat propagated forward in an arc pattern in the module.The simulation model was used for benchmarking and the accuracy of the model was verified by the experiment.The result showed that the simulation result was basically consistent with the experimental result,and the model had high accuracy.This study summarized the behavior of a commercial ternary battery module after nail test,and provided theoretical support for the subsequent module and PACK design.
