Dimensionamiento e implementación de un pack de baterías de ION-LITIO en un vehículo prototipo Karting eléctrico para la Carrera de Ingeniería Automotriz

Abstract

The objective of this technical project was the sizing and implementation of a lithium-ion battery pack in an electric kart prototype vehicle for the automotive engineering career, for which began with the theoretical collection of information through books, theses and scientific articles, to know the types of lithium-ion batteries and other components involved. The most appropriate type of lithium-ion battery was selected based on the parameters governing the CIA/FIA regulations. For the sizing of the battery pack, a calculation was made using a mathematical model to determine the capacity of the most appropriate battery, which indicated that the necessary consumption for the prototype should have an energy capacity of 0.823 kWh referring to 4 runs of 10 laps of an official competition, therefore, a 72V and 32Ah battery was selected. In addition, track tests were performed, obtaining an approximate speed of 10m/s, and a run of 39.34km where a consumption of 1.7 kWh and a final state of charge (SOC) of 26.23% was obtained. In conclusion, both the lithium-ion battery and the motor work and fulfill their function satisfactorily except that the motor is insufficient to take advantage of the maximum capacity that the battery can deliver. It is recommended to improve the traction system with it will get the most potential from the battery
