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.

道路感应充电系统中路面材料高频功率损耗研究

电动汽车（ev）的快速发展通过用更可持续的能源取代化石燃料，大大减少了碳排放。本文研究电动汽车无线充电技术，重点研究高频功率损耗。本文对感应功率传输（IPT）系统在各种路面材料（特别是沥青和混凝土）下的效率进行了实验研究，揭示了材料电磁特性造成的显著功率损失。本研究通过对不同频率和磁通密度下功率损耗的实证分析，为优化IPT系统设计提供了见解。本文强调了三个主要贡献：量化功率损耗密度，开发磁损耗的经验方程，以及确定路面材料对整体系统效率的重大影响。采用了17.8 kw的IPT系统来测量和验证路面材料的功率损耗。这项研究强调了跨学科方法的迫切需要，以提高IPT系统在未来自治和智慧城市应用中的可行性。
