Three-Phase Grid-Connected Electric Vehicles Charging Station with Photovoltaic Panels

One of the main reasons why people do not buy electric vehicles (EVs) is the worry that they will not have anywhere to charge them. A sustainable solution can be to put more fast chargers in more places such as the parking spots and mounting photovoltaic (PV) solar panels, which convert the sunlight into energy, on top of battery banks and charging multiple electric cars at the same time. Moreover, the main power grids, which can charge the electric cars when the light from the sun is not strong or at night, are found next to the roads. For residential application, the PV solar panels can be mounted on the roof, while the entire system is grid-connected. This paper deals with modeling and simulation of three-phase grid-connected EVs charging stations with PV solar panels. The EVs charging station with PV solar panels model charging of three EV batteries from a dc fast charger unit. The model is presented in detail and validated by simulation in the Matlab/Simulink environment. Finally, simulation examples display the results for three-phase supply voltage and line current, dc bus voltage and current, battery terminal voltage and output charging current, battery state of charge, charging status, and others versus time. This work is useful for power electronics specialists who need an easy and right method to design and simulate three-phase grid-connected EVs charging stations with PV solar panels.
