Abstract

A roadway section enables dynamic wireless power transfer to a vehicle and comprises pavement material and wireless power chargers. The pavement material extends along a longitudinal axis. The wireless power chargers are spaced apart along the longitudinal axis and include first, second and third conductive elements each being configured to emit a magnetic field. The second conductive element is adjacent to and spaced apart from the first conductive element at a first distance along the longitudinal axis. The third conductive element is adjacent to and spaced apart from the second conductive element at a second distance along the longitudinal axis that is longer than the first distance. The third conductive element is angled toward the second conductive element.

A roadway section for enabling dynamic wireless power transfer to a vehicle, the roadway section comprising:

pavement material extending along a longitudinal axis and having a top surface;
and
first, second and third wireless power chargers spaced apart along the longitudinal axis and respectively comprising first, second and third conductive elements each being configured to emit a magnetic field for dynamic wireless power transfer to the vehicle, wherein—
the second conductive element is adjacent to the first conductive element and spaced apart from the first conductive element at a first distance along the longitudinal axis,
the third conductive element is adjacent to the second conductive element and spaced apart from the second conductive element at a second distance along the longitudinal axis that is longer than the first distance,
the third conductive element has a center of gravity,
a first imaginary axis extends through the center of gravity of the third conductive element and a point of the top surface closest to the center of gravity,
an imaginary plane intersects the center of gravity of the third conductive element, the closest point of the top surface, and a point on the second conductive element that is closest to the third conductive element,
the third conductive element includes:
(i) a first segment proximal to the second conductive element and having a first uppermost point in the imaginary plane, and (ii) a second, opposite segment distal from the second conductive element and having a second uppermost point in the imaginary plane,
a theoretical line drawn between the first and second uppermost points defines an angle of slope of the third conductive element relative to the first imaginary axis, within the imaginary plane, wherein the angle is measured within the imaginary plane between the theoretical line and the first imaginary axis in a direction extending from the first segment toward the second conductive element, the angle being at least ninety and one-half degrees (90.5°).
