Abstract
The rapid advancement of electric vehicles (EVs) offers a significant reduction in carbon emissions by replacing fossil fuels with more sustainable energy sources. This article studies wireless charging technology for EVs, focusing on high-frequency power losses. It presents an experimental investigation into the inductive power transfer (IPT) system’s efficiency under various pavement materials (specifically, asphalt and concrete), revealing significant power losses due to material electromagnetic properties. This research provides insights into optimizing IPT system design through empirical analysis of power losses across different frequencies and magnetic flux densities. Three main contributions are highlighted: quantifying power loss density, developing an empirical equation for magnetic losses, and identifying the significant impact of pavement materials on overall system efficiency. A 17.8-kW IPT system is implemented to measure and validate the power losses in pavement materials. This research underscores the critical need for interdisciplinary approaches to enhance the feasibility of IPT systems for future autonomous and smart city applications.
