Simulação e optimização de sistemas de refrigeração de baterias em veículos eléctricos

Abstract

The present work analyses and optimises the thermal management of lithium-ion batteries in electric vehicles using Computational Fluid Dynamics (CFD) simulation. Thermal management of batteries is crucial for their performance and safety, as elevated temperatures can compromise their useful life and cause catastrophic failures such as degradation of materials, reduction of capacity and efficiency, internal short-circuit, and mechanical damage induced by heat. The study compares different cooling methods, including air cooling, liquid cooling, and phase change materials (PCM), utilising Ansys Fluent software for modelling and numerical analysis. The research seeks to contribute to the development of more efficient and viable thermal solutions for the electromobility sector.
