Modelling of Multi-Phase Interleaved based Universal Charging Port for Electric Vehicles

This paper presents the evolution of a multi-phase interleaved universal charging port to interconnect electric vehicles with the grid. The proposed charger facilitates users to charge their electric vehicles in any one of four modes: slow, medium, fast, and ultra-fast, optimizing the charging time and electricity bill. It can operate in manual as well as automatic mode. In manual mode, it charges the vehicle at a fixed rate, while in automatic mode, it automatically adjusts the charging rates based on the stress level of the grid. The proposed design offers economic gains to utility companies and electric vehicle users by allowing them to vary the charging rate during peak and off-peak hours. By charging during off-peak hours, users can take advantage of lower electricity rates and reduce their overall energy costs. Additionally, this design provides ancillary services to utility companies by allowing them to vary the charging rates of electric vehicles during peak hours. The performance of the proposed charger with the control algorithm is verified by simulation on MATLAB Simulink.
