Solution Overview
Problem
Notebook computers face challenges in maintaining battery health due to variable power supply environments, leading to premature aging when batteries are consistently kept at high voltage without full charging and discharging cycles.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the battery is maintained in a high voltage fully recharged state all the time, then the battery voltage is kept high, but the battery service life is shortened due to aging
Solution Approach 1:
The patent implements dynamic adjustment of rechargeable capacity rate based on actual usage patterns. The controller continuously monitors whether the electronic device is in use or idle, and adjusts the charging strategy accordingly - using smart charging mode during idle periods to limit maximum voltage and extend battery life, while switching to full charging mode when needed. This dynamic adaptation resolves the contradiction between maintaining high voltage and preserving battery service life.
Solution Approach 2:
The system changes the rechargeable capacity rate parameter from a fixed value to a variable parameter that adapts to usage conditions. By adjusting this parameter between different charging modes (smart charging with limited capacity rate versus full charging), the system optimizes the balance between voltage maintenance and battery longevity, effectively resolving the technical contradiction.
2Quantity of substance
If the battery undergoes complete recharging and discharging procedures frequently, then the battery capacity is maximized, but the battery ages faster due to repeated cycles
Solution Approach 1:
The patent implements periodic monitoring of usage patterns and adjusts charging strategies accordingly. Rather than continuously performing full charge-discharge cycles, the system periodically assesses whether the device has been idle for a threshold duration, and only then initiates smart charging mode to perform a controlled charge cycle. This periodic action reduces the frequency of complete cycles while still maintaining adequate capacity, resolving the contradiction between capacity maximization and service life extension.
3Productivity
If the rechargeable capacity rate is continuously high, then the battery charges quickly, but the battery voltage remains high for extended periods causing aging
Solution Approach 1:
The system employs feedback control by continuously monitoring the actual usage state of the electronic device and adjusting the rechargeable capacity rate in response. When the device is detected to be idle beyond a threshold time, the system feedback-adjusts the charging rate to a lower smart charging level, preventing prolonged high voltage states. This feedback mechanism enables the system to balance charging speed with battery longevity by adapting the charge rate to actual needs.

AI summary
A method for controlling battery recharging process is provided for an electronic device equipped with a battery. The method comprises entering a recharging smart mode. In the recharging smart mode, an actual capacity rate of the battery is determined. In the recharging smart mode, according to the actual capacity rate of the battery, a rechargeable capacity rate of the battery is changed. When the actual capacity rate is larger than a first capacity threshold value for a first predetermined time interval, the rechargeable capacity rate of the battery is decreased.
