Optimising Thermal Performance: A Novel Approach To Battery Cooling In Electric And Hybrid Vehicles

Abstract

The study explores thermal management strategies for Li-ion batteries crucial for Electric Vehicles and Hybrid Electric Vehicles, highlighting the challenges posed by thermal runaway and uneven temperature distribution. Active and passive cooling mechanisms are evaluated, with existing systems facing issues of weight and complexity. Addressing these limitations, a novel composite casing with variable thermal conductivity is proposed, featuring strategically placed copper pins for enhanced heat dissipation. Experimental and simulation results demonstrate the effectiveness of this approach, emphasising its potential for improving efficiency and safety in Li-ion battery systems. Overall, the study advocates for innovative thermal management solutions to meet the demands of evolving vehicle technologies.
