Battery Capacity Display Method for Accurate Full Charge Indication

Solution Overview

Problem

Consumer electronic devices experience battery loss over time, leading to incorrect display of fully charged state during charging, causing user confusion and poor experience.

Innovation Solution

A battery capacity display method that judges if a battery can be fully charged by monitoring voltage or capacity thresholds, and if not, determines the current capacity state and time duration, displaying full capacity when the time duration exceeds a preset overtime threshold to correctly indicate a fully charged state.

1Reliability

If traditional battery charging display methods are used, then the system is simple and easy to implement, but the battery fully charged state cannot be correctly displayed when battery loss occurs, leading to user confusion

Engineering Contradiction:

Improveaccuracy of fully charged state displayVSAvoidcomplexity of charging display system

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system performs preliminary actions by collecting multiple historical charging curves before determining the overtime threshold. This pre-processing allows the system to establish a reference baseline for normal charging behavior, enabling accurate detection of battery loss conditions without adding real-time complexity to the charging display logic.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements feedback by continuously monitoring the actual charging curve and comparing it against historical charging curves. When the actual charging time exceeds the predetermined overtime threshold, the system provides feedback by displaying a specific icon to indicate battery loss, thereby correcting the display accuracy without requiring complex user intervention.

Inventive Principle:

Principle #23Feedback

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system performs preliminary actions by collecting multiple historical charging curves before determining the overtime threshold. This pre-processing allows the system to establish a reference baseline for normal charging behavior, enabling accurate detection of battery loss conditions without adding real-time complexity to the charging display logic.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system uses a disposable approach by relying on pre-collected historical charging curve data rather than maintaining complex real-time models. The historical data serves as a simple, static reference that can be easily stored and compared, avoiding the need for sophisticated continuous monitoring algorithms while still achieving reliable battery loss detection.

Inventive Principle:

Core Design Contradiction:

Solution Approach 1:

The system performs preliminary actions by collecting multiple historical charging curves before determining the overtime threshold. This pre-processing allows the system to establish a reference baseline for normal charging behavior, enabling accurate detection of battery loss conditions without adding real-time complexity to the charging display logic.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system applies partial monitoring by focusing only on the constant voltage charging phase and specifically on whether the charging time exceeds the predetermined overtime threshold. Rather than continuously analyzing all charging parameters in real-time, the system selectively monitors the critical time duration parameter, achieving sufficient precision with minimal time investment.

AI summary

A battery capacity display method and device, electronic equipment and a computer-readable storage medium are disclosed. The method comprises: judging whether a battery to be detected can be fully charged when the battery to be detected is in a constant voltage charging state (S101); if not, determining a current capacity state of the battery to be detected and monitoring a time duration of the battery to be detected under the current capacity state (S102); judging whether the time duration is greater than a corresponding preset overtime threshold (S103); and if the time duration is greater than the preset overtime threshold, displaying full capacity via a UI interface (S104).
