Estudio de los sistemas de refrigeración en vehículos eléctricos

Abstract

This End of Degree Work aims to design the cooling system of an electric Formula Student vehicle for the University of La Laguna. This project arose to respond to a FSULL vehicle malfunction: the high engine temperature, controller and battery pack. Therefore, through this End-of-Grade Work, the intention is to design the cooling system necessary to maintain the optimum operating temperature in those parts, so that the duration and performance do not degrade. To do this, a cooling system was designed using air as a battery cooling fluid; and water for the engine and controller; both by forced convection. First, a theoretical basis was carried out on the parts of an electric vehicle, especially the battery, engine and controller; in addition to a study on the different cooling systems for this equipment. Next, the most suitable cooling system for the FSULL vehicle was made among the different existing proposals. Finally, the necessary calculations were developed for the choice of equipment that constitutes the system.
