Rechargeable Battery Storage Protocol for Preset State of Charge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rechargeable batteries face challenges in maintaining optimal state of charge for extended storage, as existing methods do not effectively account for environmental conditions and historical usage, leading to potential degradation and reduced lifespan.
Innovation Solution
A method and system that utilize battery data, environmental data, and historical data to determine and implement a storage protocol, which involves discharging the battery to a preset state of charge level and preventing recharging until manually overridden, using a network-connected battery management system that communicates with both the battery and charger to manage the discharge process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the battery is stored at a high state of charge, then the battery is ready for immediate use, but the battery experiences accelerated degradation and reduced lifespan during extended storage
Solution Approach 1:
The system performs preliminary discharge action before storage to optimize battery life. The storage protocol automatically discharges the battery to a preset state of charge level (e.g., 40-60%) before extended storage begins, preventing degradation while maintaining readiness for future use.
2Reliability
If the battery is discharged to extend storage life, then the battery lifespan is optimized, but the battery requires additional charging time before use
Solution Approach 1:
The system performs the discharge action in advance during the storage period, so when the battery is needed, it is already at the optimal charge level. This eliminates the need for additional charging time before use, as the discharge was performed preliminarily during storage.
3Adaptability or versatility
If a manual override is allowed for the storage protocol, then user flexibility is improved, but the automation of battery management is reduced
Solution Approach 1:
The system dynamically adjusts between automatic and manual modes based on user needs. The storage protocol operates automatically under normal conditions, but allows manual override when users have specific requirements, creating a flexible hybrid system that adapts to different scenarios.
4Reliability
If environmental conditions are monitored and used to adjust storage protocol, then battery optimization is improved, but system complexity increases
Solution Approach 1:
The system implements feedback by monitoring environmental conditions (temperature, humidity) and automatically adjusting the storage protocol based on the monitored data. When suboptimal conditions are detected, the system modifies discharge parameters to compensate, creating a closed-loop control system that optimizes battery storage without requiring complex user intervention.
