Simulation of Three Phase Bidirectional 10kW Charger for Electric Vehicle with G2V/V2G Mode

Electric vehicles (EV) are the most demanding and need of hour technology based on sustainability and charging infrastructure is the vital part of EV ecosystem. Bidirectional charger supports flow of power in both directions resulting in Grid to Vehicle (G2V) and Vehicle to Grid (V2G) modes of operation which result in maximum utilization of power when in need. Here the simulation study of bidirectional charging system using Simulink/Matlab with rated power of 10kW is proposed. The system uses IGBT based inverter bridge and MOSFET based bidirectional buck boost converter. The front end converter controller block used to maintain 800V dc across dc bus and inverter control and buck boost converter controller block used to control battery charging/discharging current. This model purpose is to charge the EV battery from grid and discharge the EV battery to the grid which is also proof of two way power exchange in EVs. Battery considered for this study is lithium ion with capacity of 300Ah.
