Modeling, simulation, and design of hybrid EV-battery charger for optimum grid utilization

Abstract

The rapid recent development of electric vehicles (EVs) charging system, is changing the future of the transportation sector. Thanks to Photovoltaics solar energy (PV), the EV charging operating cost is reduced, and an environmentally friendly EV is promoted to the public. In this thesis, an EV-PV-Grid charging system is modelled and simulated under PSIM software while considering and detailing the necessary control for each part in the system concerned to manage the energy coming from two different sources. The PSIM simulation and proof of concept prototype results of the developed model illustrate the performance of the realized model while indicating the battery charging state as well as the power flow between the grid, battery and PV for different irradiation.
