Analysis of a Bi-Directional (V2G and G2V) Battery of Electric Vehicle Designed in Matlab Simulink

Electric Vehicles (EVs) have a lot of advantages over cars that run on gas or diesel. Also, making transportation systems run on electricity would make it possible to make more electricity from CO2 free and Renewable energy sources like wind energy, solar energy, and hydro energy because EVs are spread out and move around a lot and need a lot of power to charge and discharge, it is important to figure out how to control how they charge and discharge so that the future smart grid can make the most use of renewable resources. In this study, a new way to control two-way chargers for electric vehicles is shown. The charger is made up of two power converters that can work in both directions. Two types of converters are described here: one is an AC-DC converter that provides a constant DC link voltage and the other is a buck-boost converter. The Buck-boost converter is responsible for both charging the vehicle from the grid (known as G2V charging) and discharging the vehicle back into the grid (known as V2G charging). The charging station’s bidirectional DC-DC converter modules handle battery charging and discharging. A model designed in MATLAB Simulink and analyzed the battery output it’s proved that the bidirectional controller prototype works well with this control method. Dynamic charging and discharging are components of the control strategy.
