Análise do carregamento elétrico veicular pelo sistema fotovoltaico off-grid

Abstract

This study presents an analysis of electric vehicle charging stations (eletropostos) based on off-grid solar systems. The integration of electric vehicles with photovoltaic energy systems shows positive potential, being able to efficiently charge these vehicles. In this context, it is essential to calculate the capacity of off-grid photovoltaic systems, ensuring adequate infrastructure for the installation of solar modules and charging points. The analysis considers the complementarity of these systems in different regions of the country, taking into account the energy consumption for vehicle recharging, the correct sizing without access to the electrical grid, the available electric vehicle models, their consumption and range, as well as a cost comparison across various regions of Brazil. The developed methodology analyzed the implementation of off-grid charging stations in the five regions of Brazil and their results. It was concluded that the viability of off-grid charging stations is challenging, with long payback periods and low returns on investment (ROI), especially in the short and medium term. The Northeast region proved to be more favorable due to lower costs and higher energy efficiency, while the South presented greater challenges due to the need for more batteries and modules. To increase economic viability, it is recommended to negotiate better equipment prices, seek tax incentives, diversify services offered at the charging stations, and form strategic partnerships. Proper implementation can promote energy sustainability, although current conditions still present significant challenges. [resumo fornecido pelo autor]
