Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing terminal charging methods, such as fast charging algorithms, can damage batteries by applying overvoltage when the terminal is under high load and power consumption, reducing service life.
Innovation Solution
A charging adjustment method that detects real-time charging current and adjusts the charging voltage by determining a target voltage based on a preset cut-off current, preventing overvoltage damage and optimizing charging efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If overvoltage charging is performed to eliminate constant voltage charging process and increase charging speed, then charging speed is improved, but battery may be damaged by overvoltage and service time is reduced
Solution Approach 1:
The patent applies dynamics by making the charging cut-off current adjustable rather than fixed. The system dynamically adjusts the cut-off current based on real-time detection of charging current and comparison with preset values, allowing the charging parameters to adapt to different operating conditions (high load vs. normal load states), thus resolving the contradiction between charging speed and battery safety
Solution Approach 2:
The patent implements feedback by continuously detecting the real-time charging current during the charging process and using this information to determine whether to perform charging adjustment. This closed-loop control mechanism allows the system to respond to actual charging conditions and adjust the cut-off voltage accordingly, preventing overvoltage damage while maintaining efficient charging
2Power
If large load is applied to terminal to improve performance, then processing capability is improved, but charging current entering battery is reduced and floating voltage is reduced
Solution Approach 1:
The patent applies parameter changes by adjusting the cut-off voltage parameter based on the detected charging current. When high load conditions are detected (indicated by reduced charging current), the system changes the cut-off voltage parameter to prevent overvoltage, thereby adapting the charging parameters to the current power consumption state of the terminal
