Abstract

Coupled coil systems and methods are disclosed in which transmitter and receiver inductors, or coils, are coupled in a configuration for wirelessly transferring power among them. In preferred implementations, power may be transmitted and received using temporarily paired coupled coils. One preferred aspect of the invention is that the coils are not permanently affixed in physical proximity to one another, but can be moved and/or interchanged, and that the coils may be used to transmit or receive power based on their real-time relationships to other coils.

Claims

1. A method for wireless power transmission comprising:

transmitting a ping from a first power pack to a second power pack;

responding to the ping from the second power pack to the first power pack; and

transmitting power to the second power pack from the first power pack as a function of the response to the ping.

2. The method of claim 1 further comprising converting the first power pack from a power receiving mode to a power transmitting mode as a function of the response to the ping.

3. The method of claim 1 further comprising converting the first power pack from a data transmission mode to a power transmitting mode as a function of the response to the ping.

4. The method of claim 1 further comprising converting the first power pack from a data receiving mode to a power transmitting mode as a function of the response to the ping.

5. The method of claim 1 further comprising convert n, the second power pack from a power transmitting mode to a pow% er receiving mode as a function of the ping.

6. The method of claim 1 further comprising converting the second power pack from a data transmission mode to a power receiving mode as a function of the ping.

7. The method of claim 1 further comprising converting the second power pack from a data receiving mode to a power receiving mode as a function of the ping.

8. The method of claim 1 further comprising converting the first power pack from a power receiving mode to a power transmitting mode by actuating one or more switches as a function of the response to the ping.

9. The method of claim 1 further comprising converting the first power pack from a data transmission mode to a power transmitting mode by actuating one or more switches as a function of the response to the ping.

10. The method of claim 1 further comprising converting the first power pack from a data receiving mode to a power transmitting mode by actuating one or more switches as a function of the response to the ping.

11. The method of claim 1 further comprising converting the second power pack from a power transmitting mode to a power receiving mode by actuating one or more switches as a function of the ping.

12. The method of claim 1 further comprising converting the second power pack from a data transmission mode to a power receiving mode by actuating one or more switches as a function of the ping.

13. The method of claim 1 further comprising converting the second power pack from a data receiving mode to a power receiving mode by actuating one or more switches as a function of the ping.

14. The method of claim 1 further comprising:

converting the first power pack from a data transmitting mode to a pow er transmitting mode as a function of the response to the ping; and

converting the second power pack from a data receiving mode to a power receiving mode as a function of the ping.

15. The method of claim 1 further comprising:

converting the first power pack from a data receiving mode to a power transmitting mode as a function of the response to the ping; and

converting the second power pack from a data transmitting mode to a power receiving mode as a function of the ping.

16. The method of claim 1 further comprising:

converting the first power pack from a power receiving mode to a power transmitting mode as a function of the response to the ping; and

converting the second power pack from a power transmitting mode to a power receiving mode as a function of the ping.

17. The method of claim 1 further comprising:

converting the first power pack from a data transmitting mode to a power transmitting mode by actuating one or more switches as a function of the response to the ping; and

converting the second power pack from a data receiving mode to a power receiving mode as a function of the ping.

18. The method of claim 1 further comprising:

converting the first power pack from a data transmitting mode to a power transmitting mode as a function of the response to the ping; and

converting the second power pack from a data receiving mode to a power receiving mode by actuating one or more switches as a function of the ping.

19. The method of claim 1 further comprising:

converting the first power pack from a data transmitting mode to a power transmitting mode by actuating one or more switches as a function of the response to the ping; and

converting the second power pack from a data receiving mode to a power receiving mode by actuating one or more switches as a function of the pin.
