Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices face challenges in accurately tracking battery aging and capacity degradation, leading to unreliable battery condition monitoring and potential unexpected device failures due to persistent inhibition of battery relaxation states during sustained wireless operations.
Innovation Solution
A method is implemented to induce relaxation states in mobile device batteries consistently and reliably, allowing for accurate calibration and updating of capacity aging tracking, using gas gauge IC chips that target specific events such as the end of discharge or midpoint of charge, and sustain relaxation until voltage stability is achieved, enabling inside-the-device awareness of battery condition changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If wireless operations are sustained continuously, then communication functionality is maintained, but battery relaxation states are inhibited leading to inaccurate aging tracking
Solution Approach 1:
The gas gauge chip performs preliminary calibration of battery capacity aging during relaxation states before normal operation resumes. By completing the calibration action in advance during available relaxation periods, the system ensures accurate aging tracking is established before wireless operations continue without interruption.
Solution Approach 2:
The system implements periodic calibration cycles during battery relaxation states that occur naturally during device usage. The gas gauge chip detects relaxation states periodically and performs capacity aging calibration during these intervals, ensuring accurate tracking without requiring continuous interruption of wireless operations.
2Ease of operation
If battery relaxation states are inhibited during sustained wireless operations, then communication is maintained, but battery capacity aging tracking becomes unreliable
Solution Approach 1:
The gas gauge chip continuously monitors battery voltage and current to detect relaxation states in real-time. When a relaxation state is detected, the chip initiates calibration routines to update battery aging parameters. This feedback mechanism ensures that calibration occurs automatically during available relaxation periods without requiring manual intervention or disrupting wireless operations.
Solution Approach 2:
The system performs self-calibration of battery aging parameters during naturally occurring relaxation states. The gas gauge chip autonomously detects when the battery is in relaxation mode and executes calibration routines without requiring external intervention or user action, maintaining accurate tracking while preserving normal device operation.
3Measurement precision
If the gas gauge chip calibrates battery aging continuously, then tracking accuracy is improved, but device operation is interrupted
Solution Approach 1:
The calibration process is implemented periodically during battery relaxation states rather than continuously. The gas gauge chip monitors for relaxation conditions and performs calibration only during these natural intervals, ensuring accurate aging tracking without requiring continuous interruption of device operation. This periodic approach balances measurement precision with operational continuity.
Solution Approach 2:
Calibration is performed in advance during relaxation states before critical operations resume. By completing calibration during available relaxation periods, the system ensures accurate battery aging data is ready before normal device operation continues, minimizing the impact on operational duration while maintaining measurement precision.

AI summary
A method is described for managing an operating state of a battery energizing a mobile device. Active elements of a "gas gauge" IC component of the mobile device are configured or programmed based on instructions related to tracking capacity aging of the battery. An event is targeted based on the configured or programmed instructions. The targeted event corresponds to reaching an end of a discharge state of the battery, or to reaching a midpoint (relative to full charge) of a charging state of the battery. A relaxation state is induced in the battery upon the targeted event occurring.
