Battery Charging Control for Operable Time Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic apparatuses with battery power supply face challenges in maintaining an optimal operable time due to battery deterioration, where reducing full charge capacity shortens the operational time, and the battery may be depleted before a predetermined time elapses.
Innovation Solution
An electronic apparatus with a charging unit and control unit that adjusts charging conditions based on a first and second charging condition to manage battery full charge capacity, switching to a higher capacity condition when the operable time falls below a threshold to extend battery life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the full charge capacity of the battery is reduced to prevent deterioration, then the battery longevity is improved, but the operable time of the electronic apparatus becomes short
Solution Approach 1:
The patent applies dynamics by making the charging conditions adjustable and switchable between multiple modes (first charging condition with lower full charge capacity for battery protection, and second charging condition with higher full charge capacity for extended operable time). This allows the system to dynamically adapt charging parameters based on operational needs, resolving the contradiction between battery longevity and operable time by enabling users to switch between preservation-oriented and performance-oriented charging modes.
2Duration of action of moving object
If the full charge capacity of the battery is increased to extend operable time, then the operable time is improved, but the battery deteriorates faster
Solution Approach 1:
The system resolves this contradiction by implementing multiple charging conditions that can be switched dynamically. The first charging condition limits full charge capacity to protect battery longevity, while the second charging condition increases full charge capacity to extend operable time. Users can select appropriate charging modes based on whether they prioritize battery preservation or extended operation, thus resolving the trade-off between operable time and battery longevity.
3Reliability
If the charging condition is optimized for battery protection, then the battery longevity is improved, but the operable time falls below the predetermined threshold
Solution Approach 1:
The patent resolves this contradiction by providing switchable charging modes. The first charging condition optimizes for battery protection with lower full charge capacity, while the second charging condition provides higher full charge capacity to ensure operable time meets or exceeds the predetermined threshold. The system dynamically allows users to switch between these conditions based on whether battery preservation or sufficient operable time is the priority, thus resolving the contradiction between battery longevity and meeting minimum operable time requirements.

AI summary
An electronic apparatus includes a charging unit configured to charge a battery, and a control unit. The control unit is configured to control the charging unit to charge the battery based on a first charging condition, in a case where an operable time of the electronic apparatus from a charging completed state to a discharging completed state is not less than a predetermined threshold. The control unit is configured to control the charging unit to charge the battery based on a second charging condition in which a full charge capacity of the battery is greater than in the first charging condition, in a case where an operable time of the electronic apparatus from a charging completed state to a discharging completed state is less than the predetermined threshold.
