Grid-Connected Bidirectional WPT Systems for Electric Vehicle (EV) Applications

Abstract

One of the most important and soon-to-be-implemented technologies is wireless power transfer (WPT) for charging electric vehicle batteries. Bidirectional Wireless Power Transfer (BD-WPT) is being investigated intensively as a way to return power generated by electric vehicles to the grid. The impact of EV grid integration is also a source of worry. For the purpose of managing the transfer of power between the grid and the electric vehicle battery (EV battery), this study provides an in-depth examination of a complete grid-integrated BD-WPT system. In order to build vehicle and grid side controllers that provide the desired output, a mathematical model of each component of the system is presented. MATLAB simulations are used to verify analytically presented ideas (Simulink).
