SYSTEMS AND METHODS FOR WIRELESS POWER TRANSFER
First Claim
1. A system for wireless power transfer, comprising:
- one or more components including a ferromagnetic, ferrite, or other magnetic material or layers, that modify the magnitude and/or phase of an electromagnetic field and/or corresponding magnetic flux in one or multiple dimensions and/or to guide the magnetic flux in such a manner as to create a preferential path for flux flow in one or multiple dimensions; and
wherein, when one or more vehicles, mobile devices, cases, skins, battery doors, dongles, or batteries, each having one or more receiver coils or receivers associated therewith, is placed in proximity to a base unit, one or more transmitter coils of the based unit are used to inductively generate a current in the receiver coil or receiver associated with the vehicles, mobile devices, cases, skins, battery doors, dongles, or batteries, to charge or power the vehicles, mobile devices, cases, skins, battery doors, dongles, or batteries.
