ABSTRACT:
An inductive charge probe having a composite magnetic core for use in inductive battery charging apparatus for charging a battery. The charge probe is insertable into a charge port of the battery charging apparatus that is coupled to the battery. The charge probe comprises the composite magnetic core and a primary winding. The composite magnetic core includes first and second magnetic core halves comprising a high loss magnetic material that are disposed adjacent to each other and that contact each other at predetermined surfaces. First and second thermally conducting members are disposed through the first and second magnetic core halves and a gap is formed between adjacent proximal ends thereof. First and second magnetic center posts comprising low loss magnetic material abut the first and second magnetic core halves. The first and second thermal conducting members are disposed through the first and second magnetic core halves and center posts, respectively. The thermal conducting members are coupled to external heat exchangers. A gap is formed between adjacent proximal ends of the thermal conducting members and the magnetic center posts. The heat exchangers are thermally secured to peripheries of the respective magnetic center posts, and adjacent surfaces thereof are separated from each other. First and second insulators are disposed between the heat exchangers and the magnetic core halves. A magnetic disk comprising low loss magnetic material is disposed between the first and second magnetic center posts and thermally conducting members. The primary winding disposed around the magnetic disk.
