Design and MATLAB Simulation of a 4 kW Solar Hybrid EV Charging Station

Abstract

Electric vehicles (EVs) are proving to be a competitive alternative to cars that use internal combustion engines (ICEs) as the need to transition to a clean transportation system grows and the cost of utilizing fossil fuels decreases. However, the growing number of EVs is placing an enormous strain on the electrical system, particularly at quick charges. A 4kW solar-powered hybrid EV charging station that combines photovoltaic (PV) generating with battery energy storage is proposed in this article, along with its design and modeling. By providing a steady and sustainable charging mechanism, the hybrid system seeks to reduce carbon emissions and power grid usage.The planned station also prefers a three-phase power management scheme, which incorporates solar power, batteries, and the power grid to sustain power supply throughout. By injecting the extra solar energy into the grid, the overall amount of electricity needed can be decreased. The PV cell modeling, maximum power point tracking (MPPT), and efficiency-boosting smart charge controller algorithms are the main components of the system. The design offers a feasible and sustainable idea for the infrastructure supporting electric vehicles (EVs) in the future.
