Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If power transmission and reception between vehicles and grid is increased to optimize energy distribution, then energy management efficiency is improved, but battery degradation accelerates
Solution Approach 1:
The control apparatus dynamically adjusts charging and discharging rates based on real-time battery state assessments (SOC, SOH, temperature) and vehicle usage patterns. The system transitions between different power transmission modes (fast charging, slow charging, discharging to grid) depending on current conditions, optimizing the balance between energy distribution efficiency and battery protection
Solution Approach 2:
The system performs preliminary assessment of battery state and vehicle travel history before authorizing power transmission. It calculates remaining usable energy and determines appropriate charging/discharging limits in advance, preventing operations that would cause battery degradation while ensuring energy management objectives are met
2Speed
If charging and discharging operations are intensified to meet energy demand, then energy distribution speed is improved, but battery health deteriorates
Solution Approach 1:
The system dynamically modulates charging speed based on real-time battery conditions. When battery health is good and conditions permit, fast charging is enabled to meet energy demand. When temperature rises or SOC approaches critical levels, the system automatically reduces charging rate to protect battery health, creating a dynamic balance between speed and health preservation
Solution Approach 2:
The control apparatus changes operational parameters (charging current, voltage, temperature thresholds) based on battery state. It adjusts these parameters in real-time to optimize charging speed while maintaining battery health within safe operating boundaries, preventing degradation from excessive or improper charging conditions
3Ease of operation
If power flow regulation is simplified to improve system operation, then ease of operation is improved, but energy distribution efficiency decreases
Solution Approach 1:
The control apparatus autonomously manages power flow regulation without requiring complex user intervention. It self-adjusts charging/discharging parameters, monitors battery state, and makes real-time decisions based on embedded algorithms that consider multiple factors (SOC, SOH, temperature, grid conditions), providing efficient energy distribution while maintaining operational simplicity for users
