Hybrid Solar PV System for Electric Vehicles Battery Charging

Abstract

The transport sector lies amidst major challenges like air pollution because of the emission of greenhouse gases (GHGs) and dependency on nonrenewable sources like fossil fuels. To alleviate those problems in the transport sector, the Electric vehicle (EV) has the potential to be the silver lining. EV is based on electric propulsion that requires the battery to power the engine and does not emit GHGs. Albeit of the advantages, running EV is not without its drawbacks. Electricity is needed to run EV, there are many places where either a charging station is not present or the grid itself is unavailable. To tackle the problem of EV charging and exploit the abundance of solar energy available, this research proposes a solution by integrating solar photovoltaic (PV) to EV battery charger charges directly and injecting excess energy of solar back to the grid. The battery charging process is controlled using DC-DC converter. Whereas, pure sinusoidal current has been injected in grid after reducing total harmonic distortion (THD) by passing through filter. And reactive power compensation has been applied to ensure only active power is being sent to the grid. The paper presents a mathematical analysis of the model as well as a simulation on the MATLAB/SIMULINKO package.
