Análisis de la eficiencia de la recuperación de energía eléctrica mediante el uso de celdas fotovoltaicas para aplicaciones en movilidad empleado en un kart eléctrico ubicado en el Distrito Metropolitano de Quito

Abstract

The energy performance of a solar-charged electric kart was analyzed in this research. Series and parallel battery connections were implemented to meet the charging requirements during experimentation. Static and dynamic date were collected to evaluate the charging system’s behavior. It was determined that the kart’s aerodynamic resistance is insignificant due to its limited top speed. Factors such as rolling resistance, inertial force, and gravitational force were analyzed using graphical tools, revealing a directly proportional relationship between mass and total resistance. Additionally, the time slot with the highest solar radiation was identified, corresponding to 10:30 a.m. with a maximum radiation of 0.59 kW. Current and voltage generated by the solar panels were also recorded. A proposal was made to harness the solar energy potential in the parking lots located in front of and behind Block B of the Universidad Politécnica Salesiana (UPS) in the metropolitan district of Quito. This proposal involved installing solar panels on the exposed surfaces of vehicles, allowing for efficient utilization of this renewable energy source. Overall, the results indicated that the electric kart can be charged using solar panels, demonstrating its viability in electric mobility applications.
