An inductive charging apparatus for use in charging batteries of an electric vehicle. The apparatus has a power source, cooling fluid pumping and cooling apparatus, and a charge port disposed in the electric vehicle. An inductive charging coupler that is insertable into the charge port comprises a housing, a ferrite puck, and an insulated, liquid-cooled, current-carrying conductive tubular transformer coil disposed around the puck. A liquid-cooled, liquid-carrying tubular transmission cable is coupled to the power source, to the cooling fluid pumping and cooling apparatus, and to the transformer coil. The transmission cable couples current from the power source to the transformer coil, and couples cooling fluid between the cooling fluid pumping and cooling apparatus and the transformer coil. The transformer coil may be a multilevel helix, spiral fluid-cooled transformer coil such as an eight turn (although n turns are possible), two level helix, four turn spiral winding. The transformer coil comprises an insulated tube high current carrying capacity conductor that optimizes AC and high frequency losses while providing a heat exchanger for the apparatus.

1. Apparatus for use with an inductive charging system having a power source, cooling fluid pumping and cooling apparatus, a charging coupler, and a charge port disposed in an electric vehicle that is coupled to batteries thereof, and wherein the coupler is insertable into the charge port to inductively couple power from the power source to charge the batteries of the electric vehicle, said apparatus comprising: a fluid-cooled inductive charging coupler comprising a housing, a puck disposed in the housing, and an insulated, liquid-cooled, current carrying conductive tubular transformer coil disposed around the puck that forms a primary winding of the inductive charging apparatus; and a liquid-cooled, liquid-carrying tubular transmission cable coupled to the power source, to the cooling fluid pumping and cooling apparatus, and to the tubular transformer coil, for coupling current from the power source to the transformer coil, and for coupling cooling fluid through the transformer coil.
