Simulation Analysis of Heating Characteristics of Energy Storage Cabinets of LiIthium Battery Based on Thermoelectric Coupling Model

Lithium-ion batteries dominate electrochemical energy storage, but their thermal effects can significantly impact their safety. To achieve rapid and precise characterization of the operational state of lithium-ion battery storage compartments and reduce the probability of accidents, this paper conducts simulation analysis based on a thermoelectric coupling model. The battery compartment was precisely meshed, and the temperature change process un-der different charging modes was simulated according to actual conditions. It was found that the presence of an alternating current component leads to in-creased heat generation and unstable current distribution within the energy storage cabinet, further exacerbating the uneven temperature distribution. These results are significant for ensuring the safe operation of lithium-ion battery storage compartments.
