Abstract

Various techniques are described herein for calculating power consumption in wireless delivery systems. In one example, power consumption is calculated by receiving information associated with at least one portable device, identifying a discharge/charge curve associated with at least one battery in the at least one portable device, and calculating power consumption of the least one portable device based at least in part on the received information and the identified discharge/charge curve.

Claims

1. An apparatus comprising:

one or more computer readable storage media having instructions stored thereon which, when executed by one or more processing systems of a wireless power reception device, direct the wireless power reception device to;

access at least one application program interface (API) associated with an application running on the wireless power reception device to gather power consumption information associated with the application,

wherein the wireless power reception device is adapted to receive and process coherent wireless power signals, over multiple paths, from a wireless power delivery system in a multipath wireless power delivery environment; and

direct the wireless power reception device to provide the power consumption information to a power consumption determination system.

2. The apparatus of claim 1, wherein the instructions, when executed by the one or more processing systems, further direct the wireless power reception device to:

detect a triggering event,

wherein the power consumption information is provided to the power consumption determination system for determining power consumption responsive to the triggering event.

3. The apparatus of claim 2, wherein the instructions, when executed by the one or more processing systems, further direct the wireless power reception device to:

monitor a battery level of the wireless power reception apparatus,

wherein the triggering event is based, at least in part, on the battery level of the wireless power reception device falling below a threshold level.

4. The apparatus of claim 2, wherein the instructions, when executed by the one or more processing systems, further direct the wireless power reception device to:

identify a rate of power consumption of the wireless power reception device,

wherein the triggering event is based, at least in part, on the rate of power consumption of the wireless power reception device exceeding a threshold value.

5. The apparatus of claim 2, wherein the power consumption information comprises device-specific information including one or more of:

device identification information,

device manufacturer information,

device model information,

device operating system information,

information about applications currently running on the wireless power reception device,

battery status information,

battery type information,

battery model information,

device location information,

power received since last request,

information about coulombs in or out of at least one battery since a last request, or temperature information.

6. The apparatus of claim 2, wherein the instructions, when executed by the processing system, further direct the one or more processing systems to:

periodically provide the power consumption information to the power consumption determination system.

7. The apparatus of claim 2, wherein the instructions, when executed by the processing system, direct the one or more processing systems to:

process a communication received from the power consumption determination system; and

present, via the wireless power reception device, the communication.

8. The apparatus of claim 7, wherein the communication comprises one or more of a visual notification or an audio notification on the wireless power reception device.

9. The apparatus of claim 7, wherein the communication comprises a request for information from the wireless power reception device.

10. The apparatus of claim 1, wherein the power consumption determination system comprises one or more of a wireless power delivery system or a cloud-based processing system.

11. A method of providing power consumption information associated with a wireless power reception device to a power consumption determination system in a wireless power delivery environment, wherein the wireless power reception device is configured to receive wireless power from a wireless power delivery system having a wireless transmitter with multiple antennas, the method comprising:

accessing application program interfaces (APIs) associated with one or more applications running on the wireless power reception device;

gathering at least a portion of the power consumption information associated with the wireless power reception device using the APIs; and

transmitting the power usage information to the power consumption determination system.

12. The method of claim 11, wherein the APIs correspond to applications executing on a processing system of the wireless power reception device.

13. The method of claim 11, wherein the power usage information is transmitted to the power consumption determination system responsive to a triggering event.

14. The method of claim 13, wherein the triggering is based, at least in part, on a battery level of the wireless power reception device falling below a threshold level or a rate of power consumption of the wireless power reception device exceeding a threshold value.

15. The method of claim 13, further comprising:

receiving a request for information from the wireless power reception device, wherein the request comprises the triggering event.

16. The method of claim 11, wherein the power usage information is transmitted to the power consumption determination system periodically.

17. The method of claim 11, wherein the power consumption determination system comprises one or more of a wireless power delivery system or a cloud-based processing system.

18. A wireless power reception device comprising:

one or more antennas; and

control circuitry configured to;

access at least one application program interface (API) associated with one or more applications running on the wireless power reception device to gather power consumption information associated with the wireless power reception device,

wherein the wireless power reception device is adapted to receive wireless power from a wireless power delivery system; and

provide the power consumption information associated with the wireless power reception device to a power consumption determination system.

19. The wireless power reception device of claim 18, wherein the control circuitry is configured to provide the power consumption information periodically or responsive to a triggering event.

20. The wireless power reception device of claim 18, wherein the power consumption determination system comprises one or more of a wireless power delivery system or a cloud-based processing system.
