ROAD BEARING FOR ELECTRIC VEHICLE CONNECTION

摘要

A road bearing for inductive coupling to an electrical connection device of an electric vehicle includes a series of primary induction coils, a bearing surface element, and a plurality of deformation features in the bearing surface element. The series of primary induction coils are interconnected to a source of electrical power and disposed in a substantially linear array below a roadway surface and within a roadway structure, and are aligned generally parallel to an alignment of the roadway. The bearing surface element is disposed above the primary induction coils, and has an upper surface that is substantially flush with the roadway surface, has a surface flatness in the range of ±1 μm per 30 mm, and a magnetic permeability in the range of 0.9 to 2. The plurality of deformation features include depressions in the upper surface of the bearing surface element, and are configured to provide friction to vehicle wheels.
