Tóm tắt

This study evaluates thermal management strategies for Lithium Iron Phosphate (LFP) batteries in the VinFast VF3 electric vehicle under Vietnam’s tropical climate conditions. Through transient Computational Fluid Dynamics (CFD) simulations, four cooling configurations were analyzed: natural convection and three forced-air cooling designs (single-inlet/outlet, modified outlet, and dual-fan). Results demonstrate that natural convection leads to significant heat accumulation, with central battery modules reaching 40°C, a 10°C rise above ambience and a 3.5°C temperature gradient across the pack. Forced-air cooling reduced peak temperatures by 1–3 °C, with the dual-fan system achieving the best performance (37.9°C maximum temperature) and thermal uniformity. The findings highlight the inadequacy of passive cooling for compact EVs in high-temperature environments and propose optimized forced-air designs as a cost-effective solution. This work provides actionable insights for enhancing battery safety and durability in tropical urban mobility applications.
