Implementación de una batería ION-LITIO para el vehículo prototipo fórmula SAE de la Carrera de Ingeniería Automotriz

Abstract

The Formula SAE prototype vehicle owned by Automotive Engineering Career at Escuela Superior Politécnica de Chimborazo does not currently have a suitable battery to meet the purposes for which it has been designed and built, so it cannot be considered for competitions of any kind; therefore, the primary objective of the following degree work is aimed at the sizing and implementation of a lithium ferro-phosphate battery for the timely equipment of the unit mentioned. The implemented methodology included several processes, starting with an exhaustive bibliographic review of the available literature in order to have enough theoretical bases to face the project; then, with the help of software, a track was built, a vehicle with similar characteristics to the prototype was characterized, a driving cycle was obtained and a mathematical model was elaborated in which by means of simulations would be used to determine precisely the energy amount that the vehicle would consume on the track. With the values obtained considering the characteristics of the unit's engine, two modules were acquired that met the energy requirements obtained in the simulation and subsequently they were installed according to the standards established in the official regulations. By means of this methodology it was determined that the accumulators acquired for the vehicle meet all the requirements for the single seater to be taken into account for an official competition, since the voltages comply with those required by the engine and the energy capacity exceeds that obtained through simulation. Finally, it is concluded that the batteries located in the prototype are suitable for the unit to be able to withstand an endurance test in an official competition, since their capacity exceeds that obtained in the simulations.
