Roadway-powering systems can effectively improve the driving distance of electric vehicles (EVs) while releasing the overdependence on batteries. As the key technical issue, the design of primary and pickup coils determines the dynamic charging performance. In recent years, the double-D-quadrature (DDQ) pickup coil has been increasingly utilized in EV dynamic charging systems by means of the persistence and stability of move-and-charge. However, the impact of primary coils with various topologies on DDQ pickup coils has been nearly unexplored in previous studies. Accordingly, this paper presents a comparative analysis of the circular-shaped, rectangle-shaped and multi-thread primary coils for DDQ-based roadway-powering systems with an emphasis on the transmission power, energization persistence, thermal analysis, and initial investment that aims to provide technical references for further research and development of EV dynamic wireless charging systems.
