Diseño del sistema de potencia de un prototipo de vehículo mediante el uso de energía solar para la competencia de vehículos World Solar Challenge.

Abstract

The objective of the research was to “Design the power system of a vehicle through the use of solar energy to the competition of vehicles World Solar Challenge”, setting the parameters of dimensioning of a solar vehicle of competition category evolution which has the particularity of that the only source of energy to the operation comes from solar radiation. In order to obtain data of irradiation and of the energy that can be captured and stored, the data were obtained to the Atacama region in Chile, which presents the highest values of radiation on the planet. In addition, the technical bases of the race were revised in which the parameters are established to which all the participants have to be accepted. The design of a solar vehicle that adapts to the dispositions of the organization deserve taking into account various criteria, starting from the components that go from the solar energetic capture by means of a photovoltaic matrix of silicon, the subsequent conversion to electrical energy of direct current, which is stored through the use of lithium-ion or lead-acid batteries, allowing the vehicle to be able to mobilize in insignificant irradiation conditions, followed the electric energy is converted to alternating current using a power inverted, in this way, it is possible to use and electric motor with important torque, it is recommended that that it be between 1 and 5 hp. In the present study all the parameters of design were established, through the formulation of alternatives that can be considered to the implementation of this type of cars, especially considering that there is the interest of the Escuela Superior Politécnica de Chimborazo in take part in this race in representation of the country, for this reason, it is imperative that all dispositions of the race organization are accepted and they have the necessary technical elements to ensure a dignified representation because the participants come from all the world and the level is very high competitive.
