Abstract

This disclosure describes systems, methods, and apparatus related to dominant power receiving unit selection. A device may determine a presence of a first device of one or more devices on a charging area of the device, the charging area including a power transmitting surface. The device may establish a connection with the first device using one or more communication protocols. The device may identify one or more parameters associated with the first device using the established connection. The device may determine that the first device is a dominant device based at least in part on the one or more parameters.

Claims

1. A device, comprising:

at least one memory that stores computer-executable instructions; and

at least one processor of one or more processors configured to access the at least one memory, wherein the at least one processor is configured to execute the computer-executable instructions to;

determine a presence of a first device of one or more devices on a charging area of the device;

establish a connection with the first device using one or more communication protocols;

identify one or more parameters associated with the first device using the established connection; and

determine that the first device is a dominant device based at least in part on the one or more parameters.

2. The device of claim 1, wherein the one or more parameters are associated with a category of the first device.

3. The device of claim 1, wherein the one or more parameters include at least one of a temperature parameter, a current parameter, or a voltage parameter.

4. The device of claim 1, wherein the at least one processor is further configured to execute the computer-executable instructions to transmit charging power to the one or more devices based at least in part on the one or more parameters.

5. The device of claim 3, wherein the temperature parameter is based at least in part on a minimum temperature of the first device and a maximum temperature of the first device.

6. The device of claim 3, wherein the current parameter is based at least in part on a ratio of a rectifier current of the first device and a maximum current of the first device.

7. The device of claim 3, wherein the voltage parameter is based at least in part on a difference between a high rectifier voltage of the first device and a rectifier voltage of the first device.

8. The device of claim 1, wherein the one or more communication protocols include at least one of a Bluetooth Low Energy (BLE), near field communication (NFC), in-band modulation, or Wi-Fi.

9. The device of claim 1, further comprising a transceiver configured to transmit and receive wireless signals.

10. The device of claim 9, further comprising an antenna coupled to the transceiver.

11. A non-transitory computer-readable medium storing computer-executable instructions which, when executed by a processor, cause the processor to perform operations comprising:

establishing a connection between a first power receiving unit (PRU), of one or more PRUs, and a power transmitting unit (PTU) using one or more communication protocols;

determining one or more parameters associated with the first PRU;

causing to send at least one of the one or more parameters to the PTU; and

receiving an indication from the PTU that the first PRU is a dominant PRU.

12. The non-transitory computer-readable medium of claim 11, wherein the one or more parameters are associated with a category of the first PRU.

13. The non-transitory computer-readable medium of claim 11, wherein the at least one of the one or more parameters include at least one of a temperature parameter, a current parameter, or a voltage parameter.

14. The non-transitory computer-readable medium of claim 13, wherein the temperature parameter is based at least in part on a minimum temperature of the first device and a maximum temperature of the first device.

15. The non-transitory computer-readable medium of claim 13, wherein the current parameter is based at least in part on a ratio of a rectifier current of the first device and a maximum current of the first device.

16. The non-transitory computer-readable medium of claim 11, wherein the computer-executable instructions, cause the processor to further perform operations comprising causing a request to be sent to charge the device.

17. The non-transitory computer-readable medium of claim 11, wherein the computer-executable instructions cause the processor to further perform operations comprising receiving charging power based at least in part on the at least one of the one or more parameters.

18. The non-transitory computer-readable medium of claim 11, wherein the one or more communication protocols include at least one of a Bluetooth Low Energy (BLE), near field communication (NFC), in-band modulation, or Wi-Fi.

19. The non-transitory computer-readable medium of claim 11, wherein the operations to establish a connection include performing a handshake procedure for exchanging identification information with the PTU.
