Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a constant current charge management method is applied to compensate battery capacity loss, then the battery capacity can be maintained, but the charge current becomes too high or too low for different application scenarios, negatively impacting battery service life
Solution Approach 1:
The patent implements dynamic charge current regulation by introducing a dynamic factor based on real-time temperature monitoring. The charge current is adjusted according to the relationship between temperature and battery chemical reaction rates, transforming the static constant current method into a dynamic adaptive system that responds to environmental conditions and application scenarios
Solution Approach 2:
The patent changes the charge current parameter dynamically by incorporating temperature as a variable. The charge current is calculated as a function of temperature, battery capacity, and application scenario requirements, allowing the system to adapt the charge current parameter to different conditions rather than using a fixed value
2Productivity
If a large charge current is applied to rapidly charge the battery when AC power fails frequently, then the battery can be charged faster, but the charge current may be too high causing overheating and reducing battery service life
Solution Approach 1:
The patent dynamically adjusts the charge current parameter based on real-time temperature monitoring. When temperature increases indicating overheating risk, the charge current is automatically reduced. This parameter change approach allows the system to maintain high charging speed when conditions permit while preventing overheating when temperature rises
Solution Approach 2:
The patent implements a feedback mechanism where temperature is continuously monitored and used to regulate charge current. The temperature signal feeds back to the charge control system, which adjusts the charge current accordingly - increasing it when temperature is low for faster charging, and decreasing it when temperature rises to prevent overheating
3Reliability
If a small charge current is applied when the generator is started, then the generator can operate more gently, but the charge current becomes insufficient to properly charge the battery, influencing battery service life
Solution Approach 1:
The patent adjusts the charge current parameter dynamically based on temperature and application scenario. During generator operation, the system monitors temperature and battery state to determine the optimal charge current, ensuring sufficient charging efficiency while preventing excessive current that would harm the battery
Solution Approach 2:
The patent applies different charge current strategies for different application scenarios and battery states. Rather than using a uniform charge current, the system tailors the charge current to local conditions including temperature, battery capacity, and operational requirements, optimizing both charging efficiency and battery protection for each specific situation

AI summary
A method for controlling charge of a battery includes: when charging a battery, monitoring a temperature of the battery in real time, and acquiring a corresponding dynamic factor according to the temperature of the battery, wherein the dynamic factor is used for characterizing a dynamically regulating component of a charge current coefficient during the charge process; calculating a maximum allowed charge current according to the dynamic factor and preset static factors; and controlling the charge of the battery according to the maximum allowed charge current. This enables adaptive charge management according to application scenarios, which effectively avoids the situation where the charge current of the battery is too high or too low, improves the environmental adaptability of battery charging, and further extends the service life of the battery and saves costs.
