Dimensionamento e escolha do sistema de tração elétrica para um veículo tipo FSAE

Abstract

In view of the current scenario in the search for sustainability and clean energy, a study on electric vehicles has become something of great relevance. This work aims to dimension and choose an electric motor to compose the traction system of the first prototype of the HorsE-Racing team of Formula SAE electric to represent the Federal Technological University of Paraná in the national competition FSAE that takes place annually in the city of Piracicaba in São Paulo. For this it is necessary to study the demands, limitations and design requirements, as well as the study of the components that make up an electric vehicle traction system, thus seeking to choose an electric motor that enables a good performance for the vehicle. After this choice, it is still necessary to select the inverter and dimension the accumulator that, together with the electric motor, will make up the traction system. The use of the Optimum Lap software will enable the validation of the engine choice, simulating the car's performance on the competition tracks. Then, the simulations of the competition dynamic tests were carried out with the chosen and dimensioned traction system, the results obtained were satisfactory, obtaining test times that meet the team's initial objective and thus enabling the final design of the prototype in the SolidWorks software.
