Abstract
A dynamic wireless power transfer (DWPT) system using a novel three-phase transmitter/receiver design was embedded 2.4 in beneath the surface of an existing rigid pavement on US 52/US 231 in West Lafayette, Indiana, with 85 coils installed and paired with a retrofitted Class-8 Cummins electrified truck. The system successfully delivered 50–190 kW at speeds up to 65 mph with efficiencies approaching 85%, and all coils met electromagnetic balance targets; similar results were validated on a 3-coil testbed at Utah State University, with magnetic flux densities well below human exposure limits. Testing also demonstrated strong misalignment tolerance and reliable high-power delivery without active vehicle-roadway alignment technologies. In addition, the project conducted extensive public outreach in collaboration with INDOT to inform and engage the community.
