1. In an inductive charging apparatus for use in charging a battery, which apparatus comprises a charge probe that is insertable into a charge port that is coupled to the battery, and wherein the charge port comprises a housing, an opening into which the charge probe is inserted, and a secondary core surrounded by secondary windings, wherein said charge probe comprises:

  • a housing;

    a primary magnetic core disposed in the housing that comprises;

    first and second magnetic core halves comprising high loss magnetic material that are disposed adjacent to each other and that contact each other at predetermined surfaces;

    first and second magnetic center posts comprising low loss magnetic material disposed adjacent the first and second magnetic core halves;

    first and second thermal conducting members disposed through the first and second magnetic core halves and the first and second magnetic center posts and wherein a gap is formed between adjacent proximal ends thereof;

    first and second heat exchangers thermally secured to peripheries of the first and second magnetic center posts, and wherein adjacent surfaces thereof are separated from each other;

    first and second insulators disposed between the first and second heat exchangers and the first and second magnetic core halves;

    a magnetic disk comprising low loss magnetic material disposed in the gap between the first and second magnetic center posts and the thermally conducting members; and

    a primary winding disposed around the magnetic disk.
