Wireless Power Transfer System for an Autonomous Electric Vehicle

KAIST (Korea Advanced Institute of Science and Technology) and KU (Khalifa University) in UAE have been progressing joint research of the semi-dynamic wireless power transfer system for autonomous electric vehicle from year 2018. The presented semi-dynamic wireless system consists of short length (1.5m) of power line for static charging and long length (5m) of power line for dynamic charging around vehicle stop. In this paper, several important system parameters are obtained through the magnetic simulation and the prototype system is implemented in the laboratory. Finally, the performance of the presented system is verified through test result, that is, the maximum power efficiency is 90.8% for static charging and is upper 85% for dynamic charging.
