Filed:2023-05-30Pub:2023-12-14
Applicant:NANJING TECH UNIVERSITY

The present invention discloses a three-dimensional modeling method for thermal runaway of a lithium-ion battery under different state of charge (SOC) conditions based on a differential scanning calorimeter (DSC) experiment, comprising S 1 : obtaining an active material of a battery, and performing a DSC experiment to obtain a heat flow curve; S 2 : dividing the heat flow curve of the battery into a plurality of reaction peaks to obtain a reaction enthalpy of each peak of the battery; S 3 : analyzing the heat flow curve by utilizing a Kissinger equation to obtain activation energy and a pre-exponential factor; S 4 : fitting the heat flow curve of the material of the battery by using a genetic algorithm to obtain a reaction order of the active material of the lithium-ion battery; S 5 : establishing a thermal runaway model of the battery, and comparing simulation experimental results to verify the feasibility of the model; and S 6 : changing the SOC of the lithium-ion battery, and studying the influence of different SOC on the thermal runaway of the lithium-ion battery. The thermal runaway model established based on the DSC experiment according to the present invention can actually reproduce the thermal runaway reaction of the lithium-ion battery during the thermal runaway process and improve the accuracy of the model.
