Diseño y construcción de una estación de carga utilizando paneles solares aplicado para el vehículo fórmula SAE de la Carrera de Ingeniería Automotriz

Abstract

The automotive Engineering career does not have a photovoltaic charging station to supply energy for the lithium iron phosphate battery (LiFePO4) of a prototype of the SAE formula competition vehicle. Therefore, the objective of this work is to design and implement a charging station using solar panels for the SAE formula vehicle of Automotive Engineering career in Riobamba city. The methodology used for the execution of this project is the analytical and synthetic method. Through the analytical method, an efficient sizing for a photovoltaic array was carried out; through the synthetic method, a deep study of the behavior of the components suitable for the implementation of a charging station was carried out, providing reliability and safety in the charging of the SAE formula vehicle. Operation tests were carried out during the month of January 2024, considering three specific days: sunny, cloudy and rainy. Under these conditions we proceeded to measure the voltage, current and power both input and output of the Huawei 2KTL inverter, achieving an adequate charge for the battery (LiFePO4) of the SAE formula vehicle. A charging station for the SAE formula was implemented, increasing the charging capacity of two battery modules (LiFePO4) until the appropriate voltage is obtained, with a current intensity that progressively decreases as the charging threshold approaches 100%, with the purpose of extending the battery life by slow charging at a temperature within the appropriate range.
