V2G, G2V and active filter operation of a bidirectional battery charger for electric vehicles

This paper discusses the design and control of a bidirectional battery charger for Electric Vehicles, and its operation as an active power filter when connected to the local home electrical grid. The charger is also designed and controlled in order to operate during the charging of the battery from the grid and the injection of the power back to the grid when needed. The whole system is simulated using Matlab/Simulink, and the results are shown during the operation of each case, along with a management system of these different operation modes. The simulation results are analyzed, discussed and proven to comply with the existing power quality standards.
