  • Publication number: 20220131398
    Abstract: A system includes an electric mobile application having a configurable charging circuit, the configurable charging circuit including an AC charging circuit couplable to a charging station on a first side, a DC charging circuit selectively couplable to a high voltage battery of the electric mobile application on a first side, and a switch interposed between the AC and DC charging circuits, where the switch provides selective coupling between the AC charging circuit on a second side and the DC charging circuit on a second side, where the switch in a first position couples the AC charging circuit to the DC charging circuit through a first inductive coupling arrangement utilizing a magnetic component, and where the switch in a second position couples the AC charging circuit to the DC charging circuit through a second inductive coupling arrangement utilizing the magnetic component.

  • Patent number: 8575944
    Abstract: A primary device for inductive power transfer to a secondary device is disclosed. The primary device includes a primary coil, the primary device being configured to (i) operate in a first mode during which the primary coil transfers power through inductive coupling to the secondary device, and (ii) operate in a second mode during which a foreign object is detected. The primary device further includes a primary controller configured to operate the primary coil (i) using a first frequency during the first mode, and (ii) using a second frequency during the second mode. A method to detect a foreign object which is in proximity of an inductively coupled environment of a primary device is also disclosed.
