Abstract
A roadway section enables dynamic wireless power transfer to a vehicle. The roadway section comprises pavement material and a wireless power charger. The pavement material defines a pavement section volume having a top surface on which the vehicle traverses and side surfaces. The wireless power charger includes a conductive element located at least partially within the pavement section volume and is configured to emit a magnetic field toward the top surface of the pavement section volume to wirelessly transfer electric power to the vehicle. The conductive element defines a profile with an outer radius that is located at least two and a half centimeters (2.5 cm) away from the side surfaces of the pavement section volume.
