Design of High Power On Board Charger used for Charging of Electric Vehicle

Now-a-days due to rising concerns about environmental degradation majorly caused by GHG emissions, emitted by ICE powered engines, a new “sustainability mantra” is emerging at center stage. This is to electrify automotive transportation industry As a result, demand for Electric Vehicle (EV) is at pace. EVs are considered to be green as they have no tailpipe emissions exhausted from them. Since EVs are powered by electricity to charge the battery from grid. The major segment of EV is charging. Amongst the various battery charging technologies, two types of charging methods are enlisted depending upon power level and sizing of battery ie. ON Board and OFF Board charging. Accordingly, it is more preferential and beneficial to charge battery through grid. This will also facilitate the bi-directional power flow between the grid and vehicle which introduces the concept of Grid-to-Vehicle(G2V) and Vehicle-to-Grid(V2G). To emphasize this concept, this paper proposes ON Board EV charging station. The converters and their suitable controls have been implemented to analyze the system. The system is simulated in MATLAB/SIMULINK environment and fruitful results are obtained to validate the system performance.
