Engineering Contradiction Analysis
1Reliability
If charging parameters are set based on the lowest capacity battery to ensure safety, then battery safety is improved, but charging time becomes too long for larger capacity batteries
Solution Approach 1:
The charging parameter determination is changed from a static approach (fixed parameters based on lowest capacity) to a dynamic approach where parameters are adjusted according to the actual battery capacity detected during charging. The system dynamically identifies battery capacity and selects appropriate charging parameters, allowing small batteries to charge quickly while large batteries charge safely.
Solution Approach 2:
The invention changes the charging parameters (current, voltage, power) based on the detected battery capacity. Different capacity ranges correspond to different parameter sets, enabling the system to optimize charging speed for small batteries while maintaining safety for large batteries through parameter adaptation.
2Adaptability or versatility
If multiple batteries with different capacities are provided to meet user requirements, then adaptability is improved, but device complexity increases
Solution Approach 1:
The system automatically detects battery capacity and selects appropriate charging parameters without requiring user intervention or complex manual configuration. The mobile terminal itself performs the identification and parameter selection, simplifying the user interface while maintaining high adaptability.
Solution Approach 2:
The system uses feedback from voltage measurements during charging to infer battery capacity. By monitoring voltage changes and applying detection algorithms, the system receives feedback about battery characteristics and adjusts charging parameters accordingly, reducing the need for complex pre-configuration.
