Adaptive Charging Control Using Power Usage Patterns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current battery charging systems charge batteries to full capacity, which can lead to increased wear and reduced battery life due to over-charging, as different batteries have optimal charge ranges that vary based on their characteristics and usage patterns.
Innovation Solution
A system comprising a power usage pattern collector and a charging controller that monitors and analyzes the power usage behavior of a device, including consumption and charging patterns, to control the charging process, avoiding over-charging and optimizing battery health by considering individual battery characteristics and usage patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If batteries are charged to full capacity, then charging completeness is improved, but battery life deteriorates due to over-charging and increased wear
Solution Approach 1:
The system dynamically changes the charging parameter (charge level target) from fixed full capacity to variable levels based on battery characteristics and usage patterns. The charging controller adjusts the charge level parameter to optimize between charging completeness and battery life extension by preventing over-charging.
Solution Approach 2:
The system implements feedback by monitoring battery usage patterns, state of charge, and charging history to dynamically adjust charging behavior. The charging controller receives feedback from the power usage pattern collector and adjusts charging parameters accordingly to balance charging completeness with battery health preservation.
2Duration of action of stationary object
If intelligent charging control is implemented, then battery life is improved, but device complexity increases due to monitoring and analysis components
Solution Approach 1:
The charging system performs self-service by automatically monitoring its own usage patterns and making charging decisions without external intervention. The power usage pattern collector and charging controller work autonomously to extend battery life, reducing the need for user configuration or manual optimization.
Solution Approach 2:
The system merges the power usage pattern collection, analysis, and charging control functions into an integrated charging management system. By combining these functions, the patent reduces overall system complexity compared to having separate independent systems for monitoring and control.
