Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If traditional charging control systems are used, then the system structure is simple, but the control intelligence is insufficient leading to inconvenience
Solution Approach 1:
The system implements multi-parameter feedback collection including voltage data from power supply terminals, temperature data from charging terminals, and power data from both sides. This feedback mechanism enables the controller to dynamically adjust charging parameters based on real-time system state, achieving intelligent control without excessive complexity
Solution Approach 2:
The charging control system performs self-monitoring and self-adjustment by automatically collecting data from its own components (voltage, temperature, power sensors) and making autonomous decisions about charging cycle adjustment and power supply switching based on predetermined strategies, eliminating the need for complex external control systems
2Reliability
If voltage data is monitored and temperature difference analysis is conducted, then charging safety is improved, but the measurement and control complexity increases
Solution Approach 1:
The controller serves multiple functions simultaneously: it collects voltage data from power supply terminals, gathers temperature data from charging terminals, analyzes power data from both sides, performs temperature difference analysis, and controls charging cycle adjustments. This multi-functionality consolidates what would otherwise require separate systems into a single integrated controller, reducing overall measurement complexity while improving safety
Solution Approach 2:
The system performs preliminary analysis by conducting temperature difference analysis between power supply and charging terminals before making charging decisions. By pre-establishing the relationship between temperature differences and charging cycle adjustments, the system simplifies real-time control complexity while maintaining high safety standards
