Systems and methods for providing positioning freedom, and support of different voltages, protocols, and power levels in a wireless power system

A system for use in charging or powering one or more devices or batteries by wireless power, comprising:

• one or more of
• a receiver coil, associated with a receiver for use with a device or battery, which receives inductive power from a charger coil placed close to the receiver coil and configured to provide power thereto, and
• a charger coil, provided within a charger, which transmits inductive power to a receiver coil placed close to the charger coil and configured to receive power therefrom;
• a switching layer having magnetic properties and covering the one or more receiver coil or charger coil, so that, during charging or powering of a device or battery, the switching layer is layered either
• between the receiver coil and a surface of the receiver, or
• between the charger coil and a surface of the charger;
• and
• wherein one or more components are used to modify one or both the magnitude or phase of an electromagnetic field, provided by the charger coil, in one or multiple dimensions, including wherein, when the receiver coil is placed close to the charger coil, the switching layer's magnetic properties are locally modified, by one or more of a magnetic field of the receiver coil or charger coil, or by another magnetic component, to control magnetic flux within a particular region of the switching layer, including
• guiding the magnetic flux to provide localized power transfer from the charger coil to the receiver coil within the particular region of the switching layer that is generally aligned both with the receiver coil and the charger coil, while
• providing electromagnetic shielding in regions of the switching layer other than the particular region.
