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. A system for determining power consumption of a portable device, comprising:

a cloud processing system in communication with a wireless charger,

wherein the charger is configured to deliver power to at least one portable device, and

wherein the charger includes an antenna array, and

wherein the antenna array is configured to transmit radio frequency power to multiple portable devices;

wherein the at least one portable device is powered by at least one battery,

wherein the charger receives information from the at least one portable device,

wherein the charger transmits the information to the cloud processing system, and

wherein the cloud processing system determines power consumption of the at least one battery based on the information, and

wherein the cloud processing system determines the power consumption partially based on a discharge/charge curve associated with the at least one battery, and

wherein the discharge/charge curve is identified based at least in part on the received information.

2. The system of claim 1, wherein the at least one wireless device automatically transmits the information to the charger periodically while the charger delivers power to the at least one portable device.

3. The system of claim 1, wherein the at least one portable device transmits the information to the charger in response to a triggering event.

4. The system of claim 3, wherein the triggering event is based at least in part on a request for information from the charger.

5. The system of claim 3, wherein the triggering event is based at least in part on a battery level of the at least one portable device falling below a threshold level.

6. The system of claim 3, wherein the triggering event is based at least in part on a rate of power consumption of the at least one portable device exceeding a threshold value.

7. The system of claim 1, wherein the information includes at least one of the following:

device identification;

device manufacturer;

device model;

device operating system;

applications currently running on the at least one portable device;

battery status of the at least one battery;

battery type;

battery model;

device location;

power received since last request;

coulombs in or out of the at least one battery since last request;

or

temperature.

8. The system of claim 1, wherein the information includes a power consumption of each application running on the at least one portable device.

9. The system of claim 1, wherein the information includes a power consumption of one or more applications running on the at least one portable device.

10. A method for determining power consumption of a portable device, comprising:

receiving information associated with at least one portable device, wherein the portable device is capable of being wirelessly charged;

identifying a discharge/charge curve associated with at least one battery in the at least one portable device;

calculating power consumption of the least one portable device based at least in part on the received information and the identified discharge/charge curve; and

transmitting wireless power to the at least one portable device using an array of antennas,

wherein the array of antennas are configured to transmit wireless power to multiple electronic devices.

11. The method of claim 10, wherein the discharge charge curve is identified based at least in part on the received information.

12. The method of claim 10, further comprising:

requesting the information from an operating system running on the at least one portable device.

13. The method of claim 12, wherein requesting the information comprising transmitting a ZigBee message to the at least one portable device.

14. The method of claim 10, wherein information is automatically received periodically from the at least one portable device.

15. The method of claim 10, wherein the information includes at least one of the following:

device identification;

device manufacturer;

device model;

device operating system;

applications currently running on the at least one portable device;

battery status of the at least one battery;

battery type;

battery model;

device location;

power received since last request;

coulombs in or out of the at least one battery since last request;

or

temperature.

16. A non-transitory computer readable storage medium having instructions stored thereon, which when executed by one or more processors of a portable device, cause the portable device to:

access multiple application program interfaces (APIs) of the portable device;

gather information associated with usage of the portable device via the multiple APIs;

responsive to a triggering event, provide the information associated with usage of the portable device to a wireless power delivery system;

receive wireless power from a wireless transmitter with an array of antennas,

wherein the array of antennas transmits wireless power to the portable device; and

transmit information related to battery power of the portable device to the wireless transmission.

17. The non-transitory computer readable storage medium of claim 16, wherein the triggering event is based at least in part on a request for information from the charger.

18. The non-transitory computer readable storage medium of claim 16, wherein the triggering event is based at least in part on a battery level of the portable device falling below a threshold level.

19. The non-transitory computer readable storage medium of claim 16, wherein the triggering event is based at least in part on a rate of power consumption of the portable device exceeding a threshold value.

20. The non-transitory computer readable storage medium of claim 16, wherein the information includes at least one of the following:

device identification;

device manufacturer;

device model;

device operating system;

applications currently running on the portable device;

device location;

power received since last request;

or

temperature.
