Abstract

A system is descried for use in wireless charging or wireless powering. The system includes a base for wirelessly charging and/or wirelessly powering and a receiver capable of receiving electricity wirelessly from the base. The receiver is associated with a battery and/or device. The base and/or the receiver is capable of detecting and operating under a plurality of power protocols and/or a plurality of communicating protocols, thereby allowing the base to transfer electricity wirelessly to the battery and/or device in a manner consistent with a common communication and/or common power protocol shared between the base and the receiver.

Claims

1. A system for use in wireless charging and/or wireless powering, comprising:

a base for wirelessly charging and/or wirelessly powering; and

a receiver capable of receiving electricity wirelessly from the base, the receiver associated with a battery and/or device,

wherein the base and/or the receiver is capable of detecting and operating under a plurality of power protocols and/or a plurality of communicating protocols, thereby allowing the base to transfer electricity wirelessly to the battery and/or device in a manner consistent with a common communication and/or common power protocol shared between the base and the receiver.

2. The system of claim 1, wherein the receiver is associated with a battery wirelessly charged by the base.

3. The system of claim 1, wherein the receiver is associated with a device wirelessly charged or powered by the base.

4. The system of claim 1, comprising a plurality of receivers, each receiver capable of receiving electricity from the base, and each receiver associated with a different battery and/or a different device.

5. The system of claim 4, wherein the different batteries and/or devices have a common communication and/or a common power protocol.

6. The system of claim 4, wherein at least one battery and/or at least one device has a communication and/or power protocol that is not common to another battery and/or to another device of the system.

7. The system of claim 1, wherein the base transfers electricity wirelessly with an efficiency of at least about 40%.

8. The system of claim 1, wherein the base and/or the receiver include a coil optimized to operate efficiently with different protocols.

9. The system of claim 1, having coils in the base and/or in the receivers, the coils being switched between electrical paths and/or being switched or tuned by capacitors or inductors to achieve efficient power or efficient communication operation.

10. The system of claim 1, wherein the protocols use different power transfer frequencies, and/or different communication methods that allow for presence detection for the device, battery and/or base.

11. The system of claim 1, wherein the communication method between the receiver and the base includes communication through a coil as used for transfer of power, through a separate coil, through an RF or optical link, and or through a means involving RFID, Bluetooth, WiFi, Wireless USB, NFC, Felica, Zigbee and/or Wireless Gigabit (WiGig).

12. The system of claim 1, wherein the battery or/or the device is not charged and/or powered by the base in a wired manner.

13. The system of claim 9, wherein the plurality of protocols include at least one of a Wireless Power Consortium protocol, a Power Matters Alliance protocol, an Alliance for Wireless Power protocol, and/or an Apple protocol.

14. The system of claim 1, wherein the base has a substantially flat surface on which a battery and/or a device may be placed for charging and/or powering.

15. The system of claim 1, wherein the base has a substantially non-flat surface for interfacing with a battery and/or a device to be charged and/or powered.

16. A unit of a system for use in wireless charging and/or wireless powering, comprising:
