Abstract

Exemplary embodiments are directed to energy storage device security. An energy storage device may include at least one energy storage cell and a controller. The controller may be configured to request device identification data from an electronic device coupled to the energy storage device and compare the device identification data to device identification data stored in the energy storage device. The controller may be further configured to enable energy to be conveyed from the at least one energy storage cell to the electronic device if the device identification matches the stored device identification data.

Claims

1. An energy storage device, comprising:

at least one energy storage cell; and

a controller configured to;

request device identification data from an electronic device coupled to the energy storage device;

compare the device identification data to device identification data stored in the energy storage device; and

enable energy to be conveyed from the at least one energy storage cell to the electronic device if the device identification matches the stored device identification data.

2. The energy storage device of claim 1, configured to receive power from a charger via inductive coupling.

3. The energy storage device of claim 1, the controller further configured to unpair the energy storage device if a received pass code matches a pass code stored within a database of the controller.

4. The energy storage device of claim 1, the controller further configured to enable energy to be conveyed to the at least one energy storage cell from a charger if device identification data from the charger matches stored device identification data.

5. The energy storage device of claim 1, the controller further configured to receive device identification data from an electronic device and store device identification data in the energy storage device.

6. The energy storage device of claim 1, configured to pair with one or more electronic devices.

7. The energy storage device of claim 1, the controller comprising:

a database for storing the device identification data; and

logic coupled to the database and configured to close a switch to couple the at least one energy storage cell to the electronic device and open the switch to decouple the at least one energy storage cell from the electronic device.

8. The energy storage device of claim 1, the controller communicatively coupled to a controller of the electronic device.

9. The energy storage device of claim 1, configured to provide the electronic device with a sufficient amount of power to enable completion of a validation process.

10. A method, comprising:

requesting device identification data from an electronic device;

comparing the device identification data to device identification data stored in an energy storage device coupled to electronic device; and

conveying energy from the energy storage device to the electronic device if the device identification data matches the stored device identification data.

11. The method of claim 10, further comprising conveying energy from the energy storage device to the electronic device if a pass code received via a user interface of the electronic device matches a stored pass code.

12. The method of claim 10, further comprising conveying energy to the electronic device while requesting the device identification data from the electronic device and while comparing the device identification data to stored device identification data.

13. The method of claim 10, further comprising receiving and storing device identification data from at least one other electronic device.

14. The method of claim 10, further comprising disabling the energy storage device if the device identification data does not match the stored device identification data.

15. The method of claim 10, further comprising storing device identification data in the energy storage device.

16. The method of claim 15, further comprising comparing the stored device identification data to subsequently received device identification data and conveying energy to the electronic device if the received device identification data matches the stored device identification data.

17. A device, comprising:

means for requesting device identification data from an electronic device;

means for comparing the device identification data to device identification data stored in an energy storage device coupled to electronic device; and

means for conveying energy from the energy storage device to the electronic device if the device identification data matches the stored device identification data.

18. The device of claim 17, further comprising means for conveying energy to the electronic device while requesting the device identification data from the electronic device and while comparing the device identification data to stored device identification data.

19. The device of claim 17, further comprising means for receiving a pass code via a user interface of the electronic device and conveying energy from the energy storage device to the electronic device if the received pass code matches a stored pass code.

20. The device of claim 17, further comprising means for means for storing device identification data in the energy storage device.
