This thesis focuses on the use of Computational Fluid Dynamics simulations and lumped parameter models for the design, optimization, and verification of two cooling systems for high-performance electric vehicle battery packs. The discussion chronologically follows the work carried out during the pre-graduate internship at the engineering design company Podium Advanced Technologies. The first chapter of the paper describes the main cooling systems for battery packs of electric vehicles, used in the automotive industry, identifying the positive and critical aspects. The second chapter describes the design of the air-cooling system for the battery pack of the BLIZZ PRIMATIST vehicle. The discussion begins by identifying the project objective and describing the main characteristics of the vehicle.
