Embedded Controller Predictive Battery Power Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Information handling systems face catastrophic failures and corruption when performing procedures with limited battery capacity, as users are unaware of the battery's sufficiency, leading to power drainage and potential corruption during critical operations like diagnostic or remediation procedures.
Innovation Solution
An embedded controller in the information handling system monitors battery performance and anticipated power consumption, predicting whether the battery level is sufficient to complete an operation and providing power management options based on a configured policy to prevent power drainage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system performs diagnostic or remediation procedures with limited battery capacity, then the operation can be completed, but the battery may be drained causing catastrophic failure and corruption
Solution Approach 1:
The system performs preliminary assessment of battery capacity before initiating diagnostic or remediation procedures. The embedded controller evaluates whether sufficient power is available to complete the intended operation, and only proceeds if the battery can sustain the full procedure without interruption. This prevents starting operations that would drain the battery and cause catastrophic failure.
Solution Approach 2:
The system continuously monitors battery power levels during operation and provides feedback to the service module. When power levels drop below thresholds required for safe operation completion, the system alerts the user and can interrupt or cancel the operation to prevent corruption. This closed-loop feedback ensures operations are terminated before battery drainage causes failure.
2Ease of operation
If the system allows full user functions and device capabilities, then ease of operation is improved, but power consumption increases risking battery exhaustion
Solution Approach 1:
The system dynamically adjusts device capabilities and user function availability based on real-time battery power levels. When sufficient power is available, full functionality is permitted. As power levels decline, the system automatically restricts non-essential functions and prioritizes critical operations, ensuring the battery is preserved enough to complete the current task safely.
3Reliability
If the system monitors and predicts battery power levels, then operation safety is improved, but device complexity increases
Solution Approach 1:
The embedded controller performs self-service by autonomously monitoring battery power levels, predicting remaining capacity, and making power management decisions without requiring complex external monitoring systems. The controller directly communicates with the battery and service module, implementing prediction algorithms and power restriction logic within itself, thereby achieving reliable power management with minimal additional system complexity.
Data Source
AI summary
An information handling system includes an embedded controller to capture a current battery power level of a battery that is a sole source of power of the information handling system. A service module may update a configuration table with anticipated power consumption associated with a component of the information handling system, wherein the anticipated power consumption is based on an operation, and predict whether the current battery power level is sufficient to complete the operation, including comparing the current battery power level with the anticipated power consumption of the component. If the current battery power level is sufficient to complete the operation, then the service module may execute the operation. If the current battery power level is insufficient to complete the operation, then the service module may provide one or more options associated with the operation based on a power management policy.
