Photo-voltaic Powered Electric Vehicle Fast Charger

Abstract

Abstract In the last years, dominant usage of petroleum-based transportation and consumption of fossil fuels results in greenhouse gas (GHGs) emissions into the atmosphere which causes negative impacts across the globe. As the situation worsens, more people are motivated towards opting for electrified transportation. However, there are still a lot of challenges to be overcome with one of the main issues concerning the development and availability of fast charging technologies in electric vehicles (EVs). To decrease high energy demand from the grid, usage of renewable energy systems (i.e., photo-voltaic) to fast charge EVs are preferred. In this paper, high performance DC-DC boost converter controlled by PI controller is proposed with the objective to mitigate the current state of fast charging and environmental problems. The proposed converter is able to generate different output power level based on the desired preset reference voltage value. All simulation results are documented to verify the proposed photovoltaic (PV) powered EV fast charger. For simplicity, EV batteries are being replaced with one resistor as the load whereas PV panels are used to generate input power for the converter.
