Embedded Controller Battery Configuration for Accident Response
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile Information Handling Systems (IHSs) face challenges in diagnosing and handling accidents, such as drops or impacts, which can lead to hidden damage and increased support burdens for Original Equipment Manufacturers (OEMs).
Innovation Solution
The implementation of an Embedded Controller (EC) with a memory that executes program instructions to change battery settings in response to detected accidents. This includes checking an accident flag, adjusting battery charging or discharging rates, and selecting power modes based on an accident handling policy or AI/ML model analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If mobile IHSs are used to increase mobility and convenience, then user convenience and versatility are improved, but the chances for accidents such as drops and impacts increase
Solution Approach 1:
The system performs preliminary actions by detecting accidents through sensors (accelerometers, gyroscopes) and proactively modifying battery settings before damage can occur. The Embedded Controller continuously monitors for shock events and automatically adjusts battery charging/discharging rates or enters power-saving modes in response to detected accidents, preventing further damage while the device is still in the user's possession.
2Measurement precision
If traditional diagnostic methods are used after accidents, then hidden damage can be detected, but additional support burdens and diagnostic time are imposed on OEMs
Solution Approach 1:
The system enables self-service by automatically detecting accidents through integrated sensors and autonomously modifying battery settings without requiring OEM intervention. The Embedded Controller independently analyzes sensor data, determines accident severity, and executes appropriate battery configuration changes, eliminating the need for time-consuming manual diagnostics and reducing support burdens on manufacturers.
Solution Approach 2:
The system implements feedback mechanisms where sensor data from accelerometers and gyroscopes continuously monitors device status, and this information feeds back to the Embedded Controller which automatically adjusts battery settings based on detected accident patterns. This closed-loop feedback system enables real-time damage detection and response without external intervention.
3Reliability
If battery settings are modified in response to accidents, then further damage can be prevented, but additional control complexity is introduced
Solution Approach 1:
The Embedded Controller serves as an intermediary between the accident detection sensors and the battery management system. It receives raw sensor data, processes accident information, and automatically modifies battery settings without requiring complex user intervention or high-level system involvement. This intermediary layer simplifies the overall control architecture by handling the complexity of accident response in a dedicated, isolated component.

AI summary
Systems and methods for configuring a battery in response to accidents are described. In some embodiments, an Information Handling System (IHS) may include an Embedded Controller (EC), and a memory coupled to, or integrated into, the EC, where the memory comprises program instructions that, upon execution by the EC, cause the IHS to change a battery setting in response to a determination that the IHS suffered an accident.
