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 or wireless powering, comprising:

a base for wirelessly charging or wirelessly powering; and

a receiver receiving electricity wirelessly from the base, the receiver associated with a battery or device,

wherein the base or the receiver is capable of detecting and operating under a plurality of power protocols or a plurality of charging protocols that require different base operation frequencies or messages between the base and the receiver, thereby allowing the base to transfer electricity wirelessly to the battery or device in a manner consistent with a common charging or common power protocol shared between the base and the receiver of appropriate form factors.

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 or a different device.

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

6. The system of claim 4, wherein at least one battery or at least one device has a charging or power protocol that is not common to another battery 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 or the receiver include a coil optimized to operate efficiently with different protocols.

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

10. 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, or an Apple protocol.

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

12. The system of claim 11, wherein the charging methods 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, or through a means involving RFID, Bluetooth, WiFi, Wireless USB, NFC, Felica, Zigbee or Wireless Gigabit (WiGig).

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

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

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

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

a base for wirelessly charging or wirelessly powering a receiver receiving electricity wirelessly from the base, the receiver associated with a battery or device,

wherein the base is capable of detecting and operating under a plurality of power protocols or a plurality of charging protocols that require different base operation frequencies or messages between the base and the receiver, thereby allowing the base to transfer electricity wirelessly to the battery or device in a manner consistent with a common charging or common power protocol shared between the base and the receiver of appropriate form factors.

17. The unit of claim 16, wherein the base is capable of wirelessly charging or powering a plurality of receivers simultaneously.

18. The unit of claim 16, wherein the base is capable of transferring electricity wirelessly with an efficiency of at least about 40%.

19. The unit of claim 16, 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, or an Apple protocol.

20. A unit of a system that includes a base for use in wireless charging or wireless powering:

a receiver receiving electricity wirelessly from the base, the receiver associated with a battery or device,

wherein the receiver is capable of detecting and operating under a plurality of power protocols or a plurality of charging protocols that require different base operation frequencies or messages between the base and the receiver, thereby allowing the base to transfer electricity wirelessly to the battery or device in a manner consistent with a common charging or common power protocol shared between the base and the receiver of appropriate form factors.
