Development of In-Motion Wireless Power Transfer Test Bed Platform for Wireless Electric Vehicle Charger

Abstract

This paper describes a new method to model and measure in-motion wireless power transfer for a wireless electric vehicle charger to experimentally reinforce understanding of principles, characteristics, operation, communication and control of an in-motion wireless power transfer system. It uses a real-time target executable called ‘external mode’ in MATLAB/Simulink with Arduino and Wi-Fi-Shield, inexpensive and open source hardware. With an I/O real-time controller, real-time signal acquisition and real-time parameter tuning capabilities, the system can be advantageously used for experimenting, modeling, communicating and measuring. Step by step of how the proposed system may be designed for experimenting with a wireless electric vehicle charger is included. Relevant hardware usually found in the electronic market are also indicated.
