Abstract

The present disclosure is directed towards an adjusted display interface method and apparatus for displaying the charge condition of a battery in a gateway or similar device. In accordance with implementations of the present principles, a mapping is created between the actual battery charge percentage and a desired battery display condition that includes several conditional display levels configured to avoid user confusion.

First claim

The invention claimed is:

1. A method comprising:
determining a charge percentage of a battery;
providing a first output for display that indicates a maximum charge percentage for the battery if the charge percentage is determined to be above a first percentage of maximum battery charge for the battery;
determining whether the battery is at least one of being charged and currently in use if the charge percentage is below the first percentage; and
providing a second output for display that is a ratio of an actual charge percentage of the battery and the maximum charge percentage of the battery if the battery is at least one of being charged and currently in use;
wherein said determining whether the battery is at, least one of being charged and currently in use further comprises determining whether the battery has a discharge rate that is greater than a threshold.

2. The method of claim 1 , wherein said determining whether the battery is at least one of being charged and currently in use further comprises determining whether the battery charge percentage is less than or equal to 70%.

3. The method of claim 1 , wherein said determining whether the battery is at least one of being charged and currently in use further comprises determining whether the battery charge percentage is less than 80% for a period of time.

4. The method of claim 1 , wherein the discharge rate is greater than the threshold for a period of time.

5. The method of claim 1 , further comprising:
determining if the charge percentage of the battery is below a second percentage of maximum battery charge; and
commencing a charging cycle for the battery if it is determined that the charge percentage of the battery is below a second percentage of maximum battery charge.

6. The method of claim 1 , further comprising providing a third output for display of a charging indicator, wherein said third output for display does not display the charge percentage for a time period after a power interruption event has occurred.

7. The method of claim 6 , further comprising providing a fourth output for display that comprises a ratio of the charge percentage that was output for display prior to a power interruption event that has occurred and the charge percentage of the battery after the power interruption event.

8. The method of claim 1 , wherein the battery is used to operate a portion of a device during a power interruption.

9. An apparatus for providing a status display of a battery comprising:
a battery charging circuit coupled to the battery; and
a controller in communication with the battery charging circuit and being configured to
determine a charge percentage of the battery,
provide a first battery charge indicator output for display that comprises a maximum charge percentage for the battery if the determined charge percentage is greater than or equal a first percentage of maximum battery charge for the battery,
determine whether the battery is at least one of being charged and currently in use if the charge percentage is below the first percentage, and
provide a second battery charge indicator output for display that is a ratio of an actual charge percentage of the battery and the maximum charge percentage of the battery if the battery is at least one of being charged and currently in use,

wherein when said controller makes said determination as to whether the battery is being charged, the controller is further configured to determine whether the battery has a discharge rate that is greater than a threshold.

10. The apparatus according to claim 9 , wherein when said controller makes said determination as to whether the battery is being charged, the controller is further configured to determine whether the battery charge percentage is less than or equal to 70%.

11. The apparatus according to claim 9 , wherein when said controller makes said determination as to whether the battery is being charged, the controller is further configured to determine whether the battery charge percentage is less than 80% for a period of time.

12. The apparatus according to claim 9 , wherein the discharge rate is greater than the threshold for a period of time.

13. The apparatus according to claim 9 , wherein the controller is further configured to commence a charging cycle for the battery if it is determined that the charge percentage of the battery is below a second percentage of maximum battery charge.

14. The apparatus according to claim 9 , wherein the controller is further configured to provide an output for display of a charging indicator, wherein said output for display does not display the charge percentage for a time period after a power interruption event has occurred.

15. The apparatus according to claim 14 , wherein the controller is further configured to provide a third battery charge indicator output for display that comprises a ratio of the charge percentage that was output for display prior to a power interruption event that has occurred and the charge percentage of the battery after the power interruption event.

16. The apparatus according to claim 9 , wherein the apparatus further includes a telephone circuit and the battery is used to operate the telephone circuit during a power interruption.

17. An apparatus for displaying a battery status comprising:
means for determining a charge percentage of the battery;
means for providing an output for display that indicates a maximum charge percentage for the battery if the charge percentage is determined to be above a first percentage of maximum battery charge for the battery;
means for determining whether the battery is at least one of being charged and currently in use if the charge percentage is below the first percentage; and
means for providing a second output for display that is a ratio of an actual charge percentage of the battery and the maximum charge percentage of the battery if the battery is at least one of being charged and currently in use,
wherein said means for determining whether the battery is at least one of being charged and currently in use further comprises means for determining whether the battery has a discharge rate that is greater than a threshold.

18. The apparatus according to claim 17 , wherein said means for determining whether the battery is at least one of being charged and currently in use further comprises means for determining whether the battery charge percentage is less than or equal to 70%.

19. The apparatus according to claim 17 , wherein said means for determining whether the battery is at least one of being charged and currently in use further comprises means for determining whether the battery charge percentage is less than 80% for a period of time.

20. The apparatus according to claim 17 , wherein the discharge rate is greater than the threshold for a period of time.

21. The apparatus according to claim 17 , further comprising:
means for determining if the charge percentage of the battery is below a second percentage of maximum battery charge; and
means for commencing a charging cycle for the battery if it is determined that the charge percentage of the battery is below a second percentage of maximum battery charge.

22. The apparatus according to claim 17 , further comprising means for providing a third output for display of a charging indicator, wherein said third output for display does not display the charge percentage for a time period after a power interruption event has occurred.
