Özet

Wireless Power Transfer (WPT) has emerged as a promising solution for enhancing electric vehicle (EV) charging infrastructure. This study investigates the efficiency of WPT using perlite-doped composite materials as a transmission medium, aiming to improve the magnetic permeability of concrete road surfaces. The research follows a three-stage methodology: (1) preparation of composite specimens with varying perlite-to-cement ratios, (2) coil design and circuit modeling using a series-series topology, and (3) experimental validation with a Vector Network Analyzer (VNA). Results indicate that increasing perlite content significantly enhances transmission efficiency, achieving 93.6 % for 2 cm thick specimens and 92.5 % for 4 cm specimens at a resonance frequency of 117 kHz. These findings demonstrate that perlite-doped composites offer a viable alternative for integrating WPT into road infrastructure. This study contributes to the literature by combining material science and electromagnetic optimization to enhance wireless energy transfer for sustainable transportation systems.
