Review on Wireless Power Transfer in Electrified Pavements: Advancing Sustainable Urban Transportation with Magnetic Materials

Abstract

Wireless Power Transfer (WPT) technology has gained renewed attention due to its potential applications in various fields, including transportation. The concept of charging electric vehicles (EVs) wirelessly has emerged as a promising solution to address the challenges associated with traditional charging infrastructure. Since electric cars (EVs) are increasingly replacing traditional gasoline-powered vehicles, it is essential to charge EVs effectively while minimizing energy loss. WPT solutions for electrified pavements show promise as a replacement for traditional charging stations. With a focus on WPT's capacity to dynamically charge moving vehicles, this analysis examines three important electric road technologies: conductive rail power transfer, pantograph line power transfer, and WPT. According to research, power transmission efficiency is greatly increased when soft magnetic composites (SMCs) are incorporated into road materials. In order to maximize the performance of WPT systems integrated into road infrastructure, this research looks at the importance of magnetic materials, namely ferrite-based composites. High prices, efficiency improvement, safety issues, electromagnetic interference, and infrastructure durability are some of the obstacles to integrating WPT onto electrified pavements. Moreover, electrified pavements encourage the use of renewable energy sources, which makes the transportation system greener and more sustainable.
