  • Manufacturer-independent positioning system for an inductive charging process
    Patent number: 10259334
    Abstract: A method and a corresponding device are provided for positioning a vehicle over the base unit of an inductive charging system. In particular, a charging station for wirelessly transmitting electric energy to a vehicle includes a base unit which is designed to generate an electromagnetic charging field for transmitting electric energy to the vehicle. The charging station has a receiving unit which is designed to receive a request signal from a transmitting unit of a vehicle. The request signal lies in any of a plurality of different frequency ranges. The receiving unit is further designed to determine a signal strength of the received request signal.
    Type: Grant
    Filed: September 23, 2016
    Date of Patent: April 16, 2019
    Assignee: Bayerische Motoren Werke Aktiengesellschaft
    Inventors: Josef Krammer, Torsten Herzog, Stefan Drozkowski
  • Field neutralization during inductive charging
    Patent number: 10069334
    Abstract: A device and a corresponding method are provided for reducing an electromagnetic field in a vehicle. A control unit for a vehicle is designed to determine one or more properties of an electromagnetic interference field. The control unit is further designed to incite an emission unit in the vehicle to emit an opposing field which reduces a strength of the interference field in a first zone around and/or in the vehicle.
