Abstract

Systems and methods for authenticating, authorizing, and/or accounting for a power-consuming device to access a power source are described. A power access controller can manage the power source and authenticate and/or authorize the power-consuming device to access the power source based on, for example, a power profile of the power-consuming device. The power profile can indicate categories of devices for the power-consuming device, the manufacturer of the power-consuming device, and/or the device'"'"'s expected power consumption. Accounting of an amount of power consumed by the power-consuming device can also be performed.

Claims

1. A method comprising:

receiving, by a computing device and from a user device, a device profile associated with the user device;

determining, by the computing device and based on the device profile associated with the user device, an expected power consumption of the user device;

determining, by the computing device and based on the expected power consumption of the user device, whether the user device is authorized to access a power source; and

granting, based on determining that the user device is authorized to access the power source, the user device access to the power source.

2. The method of claim 1, wherein the device profile associated with the user device indicates a device identifier of the user device, a manufacturer of the user device, or a category of the user device.

3. The method of claim 1, wherein the determining whether the user device is authorized to access the power source is further based on determining whether devices categorized in a category of the user device are authorized to access the power source.

4. The method of claim 1, wherein the determining whether the user device is authorized to access the power source is further based on determining, based on the expected power consumption of the user device, whether a circuit of the power source would be overloaded if the user device is granted access to the power source.

5. The method of claim 1, wherein the expected power consumption of the user device comprises a rated power consumption of the user device or a historical power consumption of the user device.

6. The method of claim 1, wherein the determining whether the user device is authorized to access the power source is further based on determining whether the expected power consumption of the user device exceeds a threshold power consumption.

7. The method of claim 1, wherein the computing device comprises a power outlet or a charger, and wherein the receiving the device profile associated with the user device is based on the user device being connected to the power outlet or the charger.

8. A method comprising:

receiving, by a computing device and from a user device, a device profile associated with the user device, wherein the device profile associated with the user device indicates a device identifier of the user device;

determining, by the computing device and based on the device identifier of the user device, whether the user device is authorized to access a power source; and

granting, based on determining that the user device is authorized to access the power source, the user device access to the power source.

9. The method of claim 8, wherein the device profile associated with the user device further indicates a manufacturer of the user device, and wherein the determining whether the user device is authorized to access the power source is further based on the manufacturer of the user device.

10. The method of claim 8, wherein the device profile associated with the user device further indicates a category of the user device, and wherein the determining whether the user device is authorized to access the power source is further based on the category of the user device.

11. The method of claim 8, wherein the computing device comprises a power outlet or a charger, and wherein the receiving the device profile associated with the user device comprises receiving the device profile associated with the user device based on the user device being connected to the power outlet or the charger.

12. The method of claim 8, further comprising determining, based on the device profile associated with the user device, an expected power consumption of the user device, wherein the determining whether the user device is authorized to access the power source is further based on the expected power consumption of the user device.

13. The method of claim 12, wherein the expected power consumption of the user device comprises a rated power consumption of the user device or a historical power consumption of the user device.

14. The method of claim 12, wherein the determining whether the user device is authorized to access the power source is further based on determining whether the expected power consumption of the user device exceeds a threshold power consumption.
