Abstract
A vehicle is provided having a wireless battery charger that is mounted within the vehicle, and an electrostatic shield for reducing electromagnetic interference radiated by the wireless battery charger.
Claims25
A vehicle, comprising:
- electronic components mounted in or on the vehicle;
- a console comprising a base and a lid;
- and
- a wireless battery charging system, comprising:
- a wireless battery charging apparatus mounted within the base of the console, the wireless battery charging apparatus comprising:
- a primary coil that is designed to inductively couple magnetic energy for wirelessly charging a rechargeable electronic device;
- and
- an electrostatic shield disposed in the console above the primary coil of the wireless battery charging apparatus to reduce electromagnetic fields generated by the primary coil from being coupled to the electronic components of the vehicle.

A vehicle, comprising:
- electronic components mounted in or on the vehicle;
- a wireless battery charging system, comprising:
- a wireless battery charging apparatus mounted within the vehicle, the wireless battery charging apparatus comprising:
- a primary coil that is designed to inductively couple magnetic energy for wirelessly charging a rechargeable electronic device;
- and
- an electrostatic shield designed to reduce electromagnetic fields from being coupled to the electronic components of the vehicle, wherein the electrostatic shield comprises:
- a box-shaped enclosure that is made of a conductive material that is electrically coupled to the ground reference, wherein the box-shaped enclosure includes an aperture into which the rechargeable electronic device is inserted, wherein the box-shaped enclosure comprises a solid conductive material or meshed conductive material that is configured to reduce electric fields radiated by the primary coil from being coupled to the electronics components and substantially prevent the electromagnetic energy radiated by the primary coil from being received by the electronics components.
