UPS Power Resource Charging Windows for Data Center Budgets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electrical environments like data centers, existing UPS systems face challenges in managing power resource charging efficiently to maintain a stable power supply and adhere to power budgets, particularly due to variations in power usage and limitations from utility providers.
Innovation Solution
The method involves calculating distinct charging windows for each power resource based on a power budget, selecting power resources within these windows, and charging them at different levels (deep, float, or sleep) to optimize power usage, ensuring that the total power draw remains within the available capability, while also accounting for safety buffers and varying power loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If all power resources are charged simultaneously at high power, then charging speed is improved, but power budget constraints are violated and overloads occur
Solution Approach 1:
The patent segments the charging process by dividing power resources into different charging groups (first charging group and second charging group) with distinct charging windows. This segmentation allows the system to control which resources charge at high power at any given time, preventing simultaneous high-power charging that would violate power budget constraints while still enabling fast charging for individual groups during their designated windows.
2Power
If power resources are charged at different times in distinct charging windows, then power budget constraints are satisfied, but overall charging efficiency decreases
Solution Approach 1:
The patent implements periodic action by establishing distinct charging windows that repeat in a cyclic manner. Each charging window is assigned to specific power resource groups, and these windows recur periodically to allow all resources to be charged over time. This periodic structure ensures power budget compliance during each window while guaranteeing that all power resources receive charging opportunities across multiple cycles, thereby maintaining both constraint satisfaction and overall charging efficiency.

AI summary
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.
