Abstract: An apparatus for a wireless power transfer (“WPT”) pad heat management system includes a ferrite structure positioned adjacent to a coil configured to wirelessly transfer power. The apparatus includes a plurality of heat spreaders positioned along a length of a component of the ferrite structure. Each of the plurality of heat spreaders is non-metallic. The apparatus includes a trough shaped to surround at least a portion of each of the plurality of heat spreaders, wherein the trough is non-metallic. The apparatus includes a phase change material (“PCM”) in the trough where at least a portion of the heat spreaders extend into the PCM. The ferrite structure, coil, plurality of heat spreaders, trough and PCM are encased in a solid material, and each of the plurality of heat spreaders comprises a material that transfers heat from the component of the ferrite structure to the PCM.

Abstract: The present disclosure covers apparatuses and associated methods for embedding a wireless power transfer coil in concrete. In embodiments, a wireless power inductor pad embedded in concrete includes a wireless power inductor pad comprising a first and second layer of continuously strung stranded wire, each layer arranged in a circular pattern. The first layer is positioned above the second layer such that the stranded wire of the first layer is offset vertically from the stranded wire of the second layer by a vertical wire-to-wire distance. Additionally, the first layer is offset horizontally from the second layer such that the stranded wire of the first layer is offset horizontally from the stranded wire of the second layer by a horizontal wire-to-wire distance; the horizontal wire-to-wire distance being zero inches. Finally, concrete permeates between the first and second layers and between the stranded wires of each layer.
