Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If heat dissipation is controlled based on average temperature of battery module only, then control simplicity is maintained, but temperature consistency among battery clusters deteriorates
Solution Approach 1:
The patent applies local quality by implementing independent temperature control for each battery cluster rather than uniform control. The system calculates average temperature for each battery cluster separately and adjusts heat dissipation parameters individually based on local temperature characteristics, thereby improving temperature consistency while maintaining manageable control complexity through modular implementation.
2Productivity
If high rate operation is performed for long time, then power output is increased, but temperature difference among battery clusters increases
Solution Approach 1:
The patent implements dynamic temperature control by continuously monitoring temperature changes and adjusting heat dissipation parameters in real-time. The system calculates temperature rising rates and dynamically adjusts fan speeds and heat dissipation efficiency for each battery cluster, enabling the system to maintain power output while adapting to changing thermal conditions during high-rate operation.
Solution Approach 2:
The patent applies parameter changes by adjusting heat dissipation parameters (fan speed, heat dissipation efficiency) based on temperature conditions. The system changes operational parameters dynamically according to temperature rising rates and average temperatures, allowing the energy storage system to maintain high power output while controlling temperature differences through parameter optimization.
3Device complexity
If uniform heat dissipation control is applied to all battery clusters, then control simplicity is maintained, but energy efficiency deteriorates due to inconsistent currents
Solution Approach 1:
The patent applies segmentation by dividing the battery system into independent battery clusters with individual temperature control. Each battery cluster is monitored and controlled separately based on its own temperature characteristics, allowing optimized heat dissipation for each cluster. This segmentation improves energy efficiency by matching heat dissipation to actual thermal needs while maintaining reasonable control complexity through standardized control logic applied to each segment.
4Temperature
If heat dissipation efficiency is increased for all battery modules, then temperature reduction is achieved, but energy consumption increases
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting heat dissipation parameters based on actual temperature conditions. The system calculates temperature rising rates and average temperatures, then adjusts fan speeds and heat dissipation efficiency accordingly. This allows the system to achieve temperature reduction when needed while minimizing energy consumption by reducing heat dissipation when temperature conditions are acceptable.
