Abstract

An apparatus and method for configuring an electrical extension device, including measuring an electric current level being drawn from at least one of a plurality of electrical plugs by at least one of a plurality of loads; comparing the electric current level with a threshold to derive a comparison; and determining whether or not to charge the at least one of the plurality of loads based on the comparison. Additionally, the apparatus and method is for charging each of the at least one of the plurality of loads, wherein the charging is associated with a time duration, determining a charging state of one of the at least one of the plurality of loads and/or terminating the charge to the one of the at least one of the plurality of loads if the charging state indicates that it is at a fully charged capacity.

Claims

1. A method for configuring an electrical extension device, comprising:

measuring an electric current level being drawn from at least one of a plurality of electrical plugs by at least one of a plurality of loads;

comparing the electric current level with a threshold to derive a comparison; and

determining whether or not to charge the at least one of the plurality of loads based on the comparison.

2. The method of claim 1, further comprising charging each of the at least one of the plurality of loads, wherein the charging is associated with a time duration.

3. The method of claim 2, further comprising determining a charging state of one of the at least one of the plurality of loads.

4. The method of claim 3, further comprising terminating the charge to the one of the at least one of the plurality of loads if the charging state indicates that it is at a fully charged capacity.

5. The method of claim 4, wherein the comparison is a first binary indication to indicate whether the electric current level is greater than or equal to the threshold in one binary state and whether the electric current level is less than the threshold in a second binary state.

6. The method of claim 4, wherein the comparison is a quantitative value that indicates the difference and polarity between the electric current level and the threshold.

7. The method of claim 2, wherein the charging is pulse charging.

8. The method of claim 2, wherein the charging is regular (non-pulse) charging.

9. A method for configuring an electrical extension device, comprising:

measuring an electric current level being drawn from a plurality of electrical plugs by a plurality of loads;

comparing the electric current level with a threshold to derive a comparison; and

determining whether or not to charge the plurality of loads based on the comparison.

10. The method of claim 9, further comprising charging each of the plurality of loads, wherein the charging is associated with a time duration.

11. The method of claim 10, further comprising determining a charging state of one of the plurality of loads.

12. The method of claim 11, further comprising terminating the charge to the one of the plurality of loads if the charging state indicates that it is at a fully charged capacity.

13. The method of claim 12, wherein the comparison is a first binary indication to indicate whether the electric current level is greater than or equal to the threshold in one binary state and whether the electric current level is less than the threshold in a second binary state.

14. The method of claim 12, wherein the comparison is a quantitative value that indicates the difference and polarity between the electric current level and the threshold.

15. The method of claim 10, wherein the charging is pulse charging.
