Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic devices often charge batteries to a level where users mistakenly believe they are fully charged, leading to inconvenience and potential battery damage from continuous high-current charging.
Innovation Solution
An electronic apparatus with a processor that monitors and controls charging, stopping when the battery reaches a certain level and resuming charge when necessary to ensure full capacity, based on usage state information and algorithms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the battery is charged continuously to full capacity, then the battery capacity is maximized, but the battery life is reduced due to high-current charging damage
Solution Approach 1:
The charging system implements periodic charging actions by stopping charging at a first electric quantity threshold and resuming at a second electric quantity threshold. This periodic on-off charging pattern reduces continuous high-current charging damage while still achieving full battery capacity over time, resolving the contradiction between maximizing capacity and extending battery life.
2Reliability
If the battery is stopped charging at a certain level, then the battery life is extended, but the battery may not be fully charged when needed
Solution Approach 1:
The charging system uses feedback mechanisms by monitoring usage state information (charging habits, discharge patterns, time of day) to dynamically adjust charging behavior. The processor estimates when the user will need the device and schedules charging accordingly, ensuring the battery is fully charged by the needed time while still protecting battery life through controlled charging cycles.
Solution Approach 2:
The system performs preliminary actions by analyzing usage patterns and estimating future charging needs before the user actually needs the device. It proactively schedules charging to complete before the estimated usage time, so the battery is ready when needed without requiring user intervention or constant monitoring.
3Ease of operation
If the charging is controlled based on usage state information, then the charging convenience is improved, but the system complexity increases
Solution Approach 1:
The charging system provides self-service functionality by automatically monitoring its own charging state, analyzing usage patterns, and making charging decisions without user intervention. The processor autonomously determines when to start and stop charging based on embedded algorithms that analyze charging history and usage states, simplifying the user experience while managing system complexity internally.

AI summary
The disclosure provides an electronic apparatus, a charging method and a non-volatile computer readable recording medium. The electronic apparatus includes a power module and a processor coupled to the power module. The processor is configured to: obtain a charging start time point of the power module; estimate a charging recovery time point according to usage state information; when an electric quantity of the power module is greater than or equal to a first electric quantity, stop the power module from being charged continuously; and at the charging recovery time point, enable the power module to be charged to a second electric quantity, where the second electric quantity is greater than the first electric quantity.
