Abstract

See full text

A magnetizable concrete wireless power transfer pad can include a base, an inductive coil and a pillar. The base can comprise a magnetizable base concrete including concrete and first magnetizable particles, the first magnetizable particles having a magnetic permeability and a magnetic saturation. The inductive coil can be positioned directly adjacent and centered over the base, the inductive coil forming an inductive coil gap at its center inner perimeter between a conductive wire that form the inductive coil, the inductive coil having an outer perimeter, a lateral width, and a longitudinal length. The pillar can extend up from the base through the inductive coil gap, the pillar comprising a magnetizable pillar concrete including concrete and second magnetizable particles, the second magnetizable particles having a magnetic permeability and a magnetic saturation such that the base and the pillar collectively shape an external magnetic field produced by the inductive coil to increase the mutual coupling with a receiver pad, that way increasing the power transfer capabilities of the system.
