Using renewable energy sources for electric vehicles charging

Abstract

This paper presents several possibilities for electric power supply from renewable sources of electric vehicle charging stations. The supply system sizing and the economic analysis were performed using the specialized computing facility Homer energy and the local resources data needed to optimize the system were taken from the RETScreen databases. In this way we could choose the photovoltaic panels depending on the solar radiation and the wind turbines according to the wind class of the region. The location chosen for the charging stations is Huşi city, Vaslui county, at an average altitude of 82 m above sea level, accessible from the European road E581. The results obtained with the three systems analyzed by Homer simulation showed that the choice of an appropriate power charging station should take into account both the local resources and the policies to use and encourage renewable energy in order to establish the technically and financially feasibility of the system.
