Modeling and Simulation of Three-Phase Bidirectional Electric Vehicle Charger

This paper aims to investigate how an electric vehicle (EV) charger with a controller performs and affects the EV battery, integrated into the grid. A bidirectional electric vehicle charging system is designed and modeled in MATLAB/Simulink to evaluate its functionality & performance. The key questions of the study are how well the charger interacts with the grid and its effects on the battery voltage & current. The study is conducted via theoretical analysis and simulation work. The power electronics control algorithm is investigated based on total harmonic distortion (THD) analysis. Moreover, some methods for the design are presented and evaluated regarding how to improve the performance of the overall electric vehicle charger station integrated into a dynamic grid.
