Abstract

A power supply system for providing power to a device includes a power supply separate from the device, a power supply communication module attached to the power supply, and a device communication module attached to the device. The device communication module communicates voltage and/or current requirements of the device to the power supply via the power supply communication module. A power line is included between the power supply and the device. A communication line may be included between the device communication module and the power supply communication module and/or the device communication module communicates wirelessly with the power supply communication module. The communication line may be separate from the power line or part of the power line. The power line has one end that is attachable to the device.

Claims

1. A power supply system for providing power to a device, comprising:

a power supply separate from the device;

a power supply communication module attached to the power supply; and

a device communication module attached to the device, wherein

the device communication module communicates voltage and/or current requirements of the device to the power supply via the power supply communication module.

2. The power supply system of claim 1, further comprising a power line between the power supply and the device.

3. The power supply system of claim 2, further comprising a communication line between the device communication module and the power supply communication module.

4. The power supply system of claim 3, wherein the communication line separate from the power line.

5. The power supply system of claim 1, wherein the device communication module communicates wirelessly with the power supply communication module.

6. A power supply for providing power to a device separate from the power supply, comprising:

a power supply communication module for receiving specified voltage and/or current requirements of the device via a device communication module attached to the device, wherein

the power supply communication module directing the power supply to provide power having the specified voltage and/or current requirements to the device.

7. The power supply of claim 6, further comprising a power line having one end attachable to the device.

8. The power supply of claim 7, further comprising a communication line between the device communication module and the power supply module.

9. The power supply of claim 8, wherein the communication line separate from the power line.

10. The power supply of claim 6, wherein the power supply communication module communicates wirelessly with the device communication module.

11. An electronic device receiving power from a power supply separate from the device, comprising:

a device communication module for communicating specified voltage and/or current requirements of the device to a power supply communication module attached to the power supply.

12. The electronic device of claim 11, wherein the device communication module communicates with the power supply communication module via a communication line.

13. The electronic device of claim 11, wherein the device communication module communicates wirelessly with the power supply communication module.

14. A method of communicating voltage and/or current requirements of a device to a power supply, comprising the steps of:

requesting, by a power supply communication module attached to the power supply, power requirements from a device communication module attached to the device;

receiving, by the power supply communication module, specified voltage and/or current requirements of the device from the device communication module; and

supplying power having the specified voltage and/or current requirements to the device.

15. The method according to claim 14, wherein the requesting step includes attaching a power line to the device.

16. The method according to claim 14, further comprising the step of supplying power to the device communication module prior to the receiving step.

17. The method according to claim 14, wherein at least one of the requesting step and the receiving step are performed wirelessly.

18. The method according to claim 14, wherein at least one of the requesting step and the receiving step are performed using a communication line connecting the power supply communication module to the device communication module.

19. The method according to claim 14, further comprising the steps of:

receiving, by the power supply communication module, a different specified voltage and/or current requirements of the device from the device communication module; and

supplying power having the different specified voltage and/or current requirements to the device.
