Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If battery heating is performed to raise temperature for optimal charging, then charging efficiency is improved, but charging time is prolonged
Solution Approach 1:
The system performs preliminary battery temperature adjustment (heating or cooling) before the vehicle arrives at the charging station. By using GPS location data and predicting arrival time, the controller activates the battery temperature adjuster in advance to bring the battery to optimal temperature range, so that when charging begins, no additional time is needed for temperature conditioning.
Solution Approach 2:
The system dynamically adjusts the battery temperature based on real-time conditions including current temperature, predicted arrival time, and charging station information. The controller continuously monitors and adjusts heating/cooling power to reach optimal temperature exactly when the vehicle arrives at the charging station, avoiding both premature heating (which wastes time) and delayed heating (which reduces efficiency).
2Reliability
If battery temperature is adjusted in advance using GPS and navigation system, then charging performance is optimized, but system complexity increases
Solution Approach 1:
The system integrates multiple existing vehicle functions into a unified battery conditioning system. The GPS receiver, navigation system, and battery temperature adjuster are already present in modern vehicles for other purposes. The controller leverages these existing components to achieve battery temperature optimization, avoiding the need for dedicated separate systems and minimizing additional complexity.
Solution Approach 2:
The system uses the vehicle's own existing infrastructure (GPS receiver, navigation system, battery temperature adjuster) to service the battery conditioning need. Rather than requiring external equipment or complex additional systems, the vehicle's built-in components work together autonomously to optimize battery temperature based on predicted charging scenarios.
