Patent number: 5640135Abstract: An inductive charging coupler for use in an inductive charging system that minimizes damage thereto caused by shock. The charging coupler comprises a housing, and a magnetic core disposed in the housing that is comprised of a plurality of sections. A primary winding is disposed around the magnetic core, A current conductor is coupled to the primary winding for coupling current thereto. By employing smaller sections of ferrite material to form the magnetic core, there is less potential for encountering broad differences in the crystal structure of the ferrite material. These structural differences can cause the ferrite material to be more prone to crack or shatter under stress conditions, such as if the coupler is dropped during use. Also smaller ferrite pieces are lighter than a single piece of ferrite material, which causes lower distributed loads due to a shock.Type: GrantFiled: April 29, 1994Date of Patent: June 17, 1997Assignee: Delco Electronics Corp.Inventors: John T.

Patent number: 5545966Abstract: Heat exchanger that are also outer turns of secondary windings of a transformer for use in a charge port of battery charging apparatus. The outer turns may have any shape or thickness, may be air or liquid cooled, or may be vapor changers (heat pipes). Other turns of the secondary windings cannot be used in this manner because they cause excessive energy dissipation, due to proximity losses. When used to a liquid cooled turn, the present invention comprises porting liquid coolant from a cooling system including a pump, a compact heat exchanger, and a fan through the outer windings. Heat dissipation from the secondary windings of the transformer is efficiently removed by providing an internal coolant flow passage or passages formed or integrated at the center of the outer windings comprising the heat exchangers. The internal passages may be configured in several ways. One approach is to construct thin, flat, self-contained flexible coolant bladders made of metal, such as copper.Type: GrantFiled: April 29, 1994Date of Patent: August 13, 1996Assignee: Delco Electronics Corp.Inventors: Sergio Ramos, John T.
