Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a plurality of battery cells are connected in series or parallel to configure a battery pack, then high output is obtained, but heat generated from the battery cells cannot be removed effectively
Solution Approach 1:
The cooling system is segmented into multiple cooling pipes (first cooling pipe and second cooling pipe) that are positioned at different locations (upper part and lower part) of the battery cell stack, allowing heat to be removed from multiple zones simultaneously, thereby improving overall heat dissipation efficiency while maintaining high output capability
Solution Approach 2:
The cooling system transitions from conventional single-point or single-plane cooling to three-dimensional multi-level cooling by placing cooling pipes at both upper and lower parts of the battery cell stack, creating vertical heat dissipation paths that enhance thermal management effectiveness
2Device complexity
If the sealing part is disposed in the conventional manner, then the battery cell structure is simple, but the space between the upper plate and the battery cell stack cannot be utilized effectively for cooling
Solution Approach 1:
The sealing part is folded in the vertical direction to create a compact structure that minimizes space occupation in the upper region, thereby enabling effective utilization of the space between the upper plate and battery cell stack for placing cooling pipes and improving cooling efficiency
