DESIGN OF A 50 kW SOLAR PV POWERED CHARGING STATION FOR EVs

Abstract

This study investigates to design a 50-kW solar photovoltaic (PV) charging station for plug-in hybrid electric vehicles (PHEVs) to mitigate problems encountered in renewable energy utilization processes and to cope with the increasing power demand by PHEVs for the near future, because solar energy the among the cleanest source of energy which does not contribute to carbon emission as in the case of thermal or nuclear power plants hence, it is an essential connection to solving the environmental problems of how to charge PHEVs from renewable energy. The purpose is to create a highly powerful, intelligent charging network that is powered by solar energy for charging PHEVs at workplaces. This study further reduces the operating cost of PHEVs in long run makes the whole setup of the charging station more economical than conventional sources of energy. With the help of online commercial tools along with a global solar atlas, the available solar energy for one year in king hussein business park (KHBP) is calculated along with the required PV modules, maximum power point tracker, inverter, and battery bank. The annual variation in solar insolation is analyzed to determine the energy available for PHEV charging and the necessity for grid connection and PV modules are selected for the worst irradiance level. MATLAB/Simulink is used to design, integrate, and simulate the solar PV system as well as to determine the system stability and performance. The system works satisfactorily under the given conditions and can be modified by adding protection and other components to obtain a more realistic result. This study will help in commercializing the renewable energy charging station of electric vehicles and keep the environment clean.
