Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the energy storage system is optimized for vehicle performance, then power output is improved, but battery lifetime deteriorates
Solution Approach 1:
The control unit determines operational parameters in advance based on route planning information before the vehicle departs. This preliminary optimization allows the system to prepare appropriate power delivery strategies that balance performance requirements with battery protection, avoiding reactive adjustments that could harm battery life.
Solution Approach 2:
The system dynamically adjusts operational parameters such as state of charge limits, power limits, and temperature thresholds based on the specific route characteristics. This dynamic optimization allows the energy storage system to adapt its behavior to match actual driving conditions, maximizing power output when needed while preserving battery lifetime through condition-aware control.
2Use of energy by moving object
If the energy storage system is optimized for driving range, then energy efficiency is improved, but vehicle performance deteriorates
Solution Approach 1:
The system dynamically adjusts power delivery strategies based on real-time route information and vehicle conditions. When driving range optimization is prioritized, the control unit modifies power limits and state of charge parameters to maximize energy efficiency, while still maintaining sufficient power capability for performance-critical situations identified in the route plan.
3Power
If multiple battery packs are provided to meet vehicle performance requirements, then power output is improved, but system complexity increases
Solution Approach 1:
The control unit integrates control of multiple battery packs into a unified management system. By determining operational parameters for the entire energy storage system based on route planning information, the system coordinates power delivery across all battery packs simultaneously, reducing the complexity that would arise from managing each pack independently while maintaining the combined power output capability.
