Description

<p>Dynamic wireless power transfer (DWPT) has garnered significant research attention in recent years as a means to facilitate the adoption of electric vehicles. Implementing this technology requires embedding transmission coils into roadways, and numerous studies have explored the practicality of such buried coil systems. In this paper, we introduce an edgewise coil design that offers enhanced heat dissipation and cost efficiency for use as transmitting coils in DWPT systems. Experimental comparisons were conducted between traditional litz wire coils and the proposed edgewise coils, focusing on transmission characteristics and heat generation when embedded in the road. The results demonstrate that the edgewise coils maintain transmission performance comparable to that of conventional systems while reducing coil temperature rise by 4.2°C. These results underscore the potential of edgewise coils as an effective and practical alternative for DWPT applications.</p>
