Power Backup Device Charging via Component Throttling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power backup devices in information handling systems, such as server devices, experience charging interruptions due to high temperatures, leading to potential power loss and data unavailability, as they halt charging operations when air temperature exceeds a certain threshold, typically around 50-60 degrees Celsius.
Innovation Solution
An adaptive component throttling mechanism that determines when the air temperature exceeds a threshold and transmits throttling instructions to reduce the operation of components located between the power backup device and the air inlet, thereby cooling the air before allowing charging to resume once the temperature is within safe limits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If components operate at full capacity in high temperature environments, then productivity is maintained, but the air temperature exceeds the threshold and charging operations are interrupted
Solution Approach 1:
The system dynamically adjusts component operation levels based on real-time temperature monitoring. When temperature exceeds the threshold during charging, the system automatically throttles component operation to reduce heat generation, allowing charging to proceed. This dynamic adaptation resolves the contradiction by making component operation capacity variable rather than fixed, enabling the system to maintain reliability while preserving the ability to achieve high productivity when conditions permit.
Solution Approach 2:
The system changes the operational parameters of components (specifically the operation level or power consumption) in response to temperature conditions. By adjusting the operation parameter downward when temperature is high, the system reduces heat generation to enable charging operations. This parameter change strategy allows the system to balance productivity and reliability by modifying operational characteristics based on environmental conditions.
2Reliability
If components are throttled to cool the air, then charging operations can proceed, but productivity is reduced due to lower component operation
Solution Approach 1:
The system implements periodic monitoring of temperature conditions and alternates between full operation mode and throttled operation mode as needed. During normal temperature conditions, components operate at full capacity for maximum productivity. When temperature exceeds thresholds, the system periodically throttles operation to enable charging, then resumes full operation when temperature drops. This periodic switching resolves the contradiction by confining productivity reduction to only the necessary duration for safe charging.
Solution Approach 2:
The system makes component operation capacity dynamic rather than static, adjusting it in real-time based on temperature feedback. This dynamic approach allows the system to maintain high productivity during favorable conditions while temporarily reducing operation only when necessary for charging safety, thus minimizing the overall impact on productivity while ensuring charging continuity.
3Device complexity
If conventional charging control is used without component throttling, then system complexity is low, but charging interruptions occur in high temperature environments
Solution Approach 1:
The system implements a feedback mechanism where temperature sensors continuously monitor air temperature near components, and this information feeds back to the charging control system. When the feedback indicates temperature exceeds the threshold, the system automatically activates component throttling to enable charging. This feedback loop adds moderate complexity but dramatically improves charging reliability in high temperature environments by creating a closed-loop control system that automatically responds to thermal conditions.
Solution Approach 2:
The system introduces an intermediary control mechanism that mediates between the charging system and the components. This intermediary layer monitors temperature conditions and coordinates the throttling of component operation to enable charging. The intermediary adds some complexity but provides a structured way to manage the interaction between charging operations and thermal conditions, improving reliability without requiring complete system redesign.

Data Source
AI summary
A component throttling power backup charging system includes a chassis defining a chassis housing and a chassis air inlet to the chassis housing, at least one component located in the chassis housing and adjacent the chassis air inlet, and a power backup device located opposite the at least one component from the chassis air inlet. The power backup device determines that a charging condition has been satisfied. The power backup device then determines that a temperature of air being provided to the power backup device exceeds a threshold temperature and, in response, transmits a throttling instruction that is configured to cause throttling of the at least one component. The power backup device subsequently determines that the temperature of the air being provided to the power backup device no longer exceeds the threshold temperature and, in response, performs charging operations.
