Bidirectional Battery Charger: Design, Analysis and Simulation for Electric Vehicle

This paper work proposes a design for a bidirectional electric vehicle charger that can transfer power from the grid to evaluate its functionality and performance, a bidirectional electric vehicle charging system is designed and modelled in MATLAB/Simulink.to the vehicle as well as from the vehicle to the grid. A simple power electronics topology is used. The primary goal of the research is to determine how well the charger interacts with the grid and its effects on battery voltage and current. In this research we work on the initial state of charge of battery is 80%. We can see the simulation output of SOC (%) of the battery for both grid to vehicle and vehicle to grid. In the mode of operation, the SOC (%) is increasing by 80% in Grid to Vehicle and decreasing by 80% in Vehicle to Grid. We can also find in this research voltage graph for grid to vehicle and vehicle to grid. In the voltage graph we can measure the Grid Voltage, Inverter Voltage and Grid and Inverter Voltage [34].
