Estudio e implementación de un kit de baterías para un go kart eléctrico para la carrera de Ingeniería Automotriz

Abstract

This technical project deals with the sizing of a battery kit for an electric Go Kart, which is intended for future competitions on behalf of Automotive Engineering of ESPOCH, making use of alternative energies in order to reduce environmental pollution as well as noise. The Go kart of the automotive engineering career, does not have a battery kit that can meet the required energy demand, for this reason the objective is to size a kit from an analysis on an internal combustion engine and implement it in the single-seater. The methodology has an analytical and comparative orientation since the research requires the collection and evaluation of data with information for the project, through the application of the VBOX sport device, a series of parameters such as speed, acceleration, altitude, and time were obtained. To proceed to perform dynamic calculations, using the weighted criteria method that evaluates the most important data, obtaining a result of 1.4 kW of power at the output of the battery, with this value the EVE lithium ion battery is selected. Subsequently, the battery was mounted on the Go kart chassis in order to be able to travel on tracks. Once the assembly of the electric train elements was completed, autonomy tests were carried out to compare the efficiency of the electric Go kart. The sizing leaves as a result a Lithium Ion battery of EVE brand of 60v and 20A, achieving a power of 1,2 kW having as an advantage a high energy efficiency and prolonged life and it is recommended to perform constant monitoring of the SOC, which should not decrease from 40%, to take care of the battery life.
