Abstract

Systems, methods, and computer-readable and executable instructions are provided for moderating a charging for a number of power resources. Moderating a charging for a number of power resources can include calculating a distinct charging window for each of the number of power resources. Moderating a charging for a number of power resources can also include selecting a first power resource from the number of power resources based on a current time and the distinct charging window for the first power resource. Furthermore, moderating a charging for a number of power resources can include charging the first power resource within the distinct charging window before charging a second power resource.

Claims

1. A method for moderating a charging for a number of power resources, comprising:

utilizing a processor to execute instructions on a non-transitory computer readable medium for;

calculating a distinct charging window for each of the number of power resources;

selecting a first power resource from the number of power resources based on a current time and the distinct charging window for the first power resource; and

charging the first power resource within the distinct charging window before charging a second power resource.

2. The method of claim 1, wherein calculating the distinct charging window includes assigning a power resource number to each of the number of power resources.

3. The method of claim 1, wherein charging the first power resource comprises charging the first power resource at a first charge level while continuing to charge a remaining number of power resources at a second charge level.

4. The method of claim 1, further comprising calculating a charge level for each of the number of power resources, wherein a total charge level is within a predetermined power budget.

5. The method of claim 1, wherein calculating the distinct charging window includes determining a first charging level for the first power resource and a second charging level for a remaining number of power resources.

6. The method of claim 1, further comprising:

determining a charge status of the first power resource, wherein determining the charge status comprises determining an available load from a current load of the system and the overall power budget.

7. A non-transitory computer-readable medium storing a set of instructions executable by a processor to cause a computer to:

calculate a time for a distinct charging window based on a number of criteria;

assign the distinct charging window to each of a number of power resources;

determine a selected power resource from the number of power resources based on the current time and the distinct charging window for the selected power resource; and

start a charger during the distinct charging window to charge the selected power resource at a first rate while a remaining number of the number of power resources charge at a second rate.

8. The medium of claim 7, wherein the instructions execute to maintain a combined power consumption of the selected resource at the first rate and the remaining number of the number of power resources at the second rate is below a predetermined threshold.

9. The medium of claim 7, wherein the instructions execute to maintain the first rate at a power level greater than a power level at the second rate.

10. The medium of claim 7, further comprising instructions executed to transition to charge the selected power resource at the second rate when the charge status is above the predetermined threshold.

11. The medium of claim 7, wherein the distinct charging window is calculated individually for each of the number of power resources utilizing a number of real time clocks and a reference time.

12. A system for moderating a charging for a number of uninterruptible power supply (UPS) units, the system comprising:

a number of advanced power managers (APM) communicatively coupled to the number of UPS units, wherein each of the APM comprises a processing resource in communication with a non-transitory computer readable medium, wherein the non-transitory computer readable medium includes a set of instructions and wherein the processing resource executes the set of instructions to;

receive a distinct charging window for a coupled UPS unit;

determine a charge status of the UPS unit;

enable a deep charger to charge the coupled UPS unit at a first rate when within the distinct charging window and when the charge status is below a predetermined threshold; and

enable a float charger to charge the coupled UPS at a second rate when outside the distinct charging window.

13. The system of claim 12, wherein each of the APM units maintain a one to one relationship between each APM and corresponding UPS unit.

14. The system of claim 12, wherein instructions are executed by the APM to regulate power consumption for the UPS unit and for a number of other devices operating within an overall power budget.

15. The system of claim 14, wherein instructions are executed by the APM to cap power consumption of the number of other devices.
