Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the battery is operated in low-temperature environment without preheating, then the vehicle can be used immediately, but the battery will be fully frozen causing performance degradation and structural damage
Solution Approach 1:
The system performs preliminary preheating of the battery based on predicted low-temperature duration before the battery is fully frozen. By calculating the duration between vehicle usage time and arrival of preset weather, the system activates preheating in advance to maintain battery temperature above freezing point, preventing performance degradation and structural damage while ensuring the battery is ready for use.
2Reliability
If preheating is performed continuously, then the battery temperature is maintained, but energy consumption increases significantly
Solution Approach 1:
The system implements periodic preheating based on the calculated duration of low-temperature exposure. Instead of continuous preheating, the system activates heating at specific intervals or for specific durations determined by the predicted low-temperature period. This ensures the battery temperature is maintained above freezing while minimizing unnecessary energy consumption during periods when heating is not required.
3Loss of time
If the system monitors weather and usage patterns continuously, then preheating timing is optimized, but system complexity increases
Solution Approach 1:
The system utilizes existing vehicle data (usage patterns, position information) and publicly available weather forecast information to automatically determine preheating timing. The control unit calculates the duration between vehicle usage time and arrival of preset weather using simple time difference computation. This self-service approach optimizes preheating timing without requiring complex monitoring infrastructure, as it leverages data already collected by the vehicle's existing systems.
