Résumé
The reliance on Lithium-Ion Batteries (LIBs) as a primary energy source and storage system has grown significantly, particularly in the transportation sector, as a sustainable alternative to fossil fuels. However, the effective thermal management of LIBs remains a critical challenge, especially under different operational loads and varying environmental conditions. This study numerically investigates the thermal performance of an air-cooled battery thermal management system (BTMS) with circumferential fins applied to a single cylindrical LIB cell (LFP 32700). The study focuses on the impact of key parameters, including discharge rates (1C, 1.5C, and 2C), fin spacing (4-32 mm), and non-uniform distribution of fins on the surface of a battery cell using two distribution Cases. The Multi-Scale Multi-Domain (MSMD) and Equivalent Circuit Model (ECM) equations were employed to simulate battery operation loads using ANSYS-FLUENT software. The results demonstrate that an optimal spacing of 9-11 mm between the fins and an arrangement of 10 fins per battery height significantly enhances thermal performance by reducing temperature variations and improving heat transfer.
