1Duration of action of moving object
If a larger capacity and higher density battery is equipped in the terminal, then the battery life is improved, but the charging time becomes longer
Solution Approach 1:
The patent implements dynamic charging mode switching between open-loop and closed-loop modes based on real-time battery state detection. The terminal detects battery parameters (voltage, current, temperature) and dynamically adjusts the charging mode to optimize charging speed while ensuring safety, thereby reducing overall charging time for high-capacity batteries
Solution Approach 2:
The patent changes charging parameters (voltage, current) based on battery state. In open-loop mode, higher current is applied for faster charging when battery conditions permit. In closed-loop mode, parameters are adjusted based on feedback to maintain safe operating conditions, enabling efficient charging of high-capacity batteries
2Productivity
If the terminal uses higher power charging, then the charging speed is improved, but the safety and stability of charging becomes more difficult to control
Solution Approach 1:
The system dynamically switches between open-loop fast charging mode (for higher speed when safe) and closed-loop controlled charging mode (for enhanced safety when needed). This dynamic adaptation allows the system to achieve high charging speeds while maintaining safety through real-time mode adjustment based on battery conditions
Solution Approach 2:
The closed-loop charging mode implements feedback control by continuously monitoring battery parameters and adjusting charging current accordingly. This feedback mechanism ensures charging safety and stability when operating at high power levels, preventing overheating and other safety issues while maintaining efficient charging
