Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional cooling systems are used for battery modules, then the structure is simple, but cooling efficiency is significantly low due to ineffective heat dissipation
Solution Approach 1:
The cooling system is segmented into multiple independent cooling plates (first cooling plate and second cooling plate) that can be separately positioned on different sides of the battery cell. Each cooling plate independently dissipates heat from its respective side, allowing for modular heat management that improves efficiency without requiring a monolithic complex structure
Solution Approach 2:
A heat transfer member is introduced as an intermediary substance between the battery cell and the cooling plates. This heat transfer member fills the gaps and enhances thermal contact, enabling more effective heat transfer from the battery cell to the cooling plates without requiring direct rigid contact, thus improving heat dissipation efficiency while maintaining structural flexibility
2Productivity
If battery modules operate for elongated periods, then energy capacity is utilized, but internal temperature rises rapidly causing shortened lifespan and potential ignition
Solution Approach 1:
The cooling plates are positioned to contact both sides of the battery cell simultaneously, creating continuous heat dissipation action throughout the battery module during operation. This continuous cooling action prevents temperature accumulation over extended operation periods, allowing the battery to maintain safe temperatures throughout its operational lifespan
Solution Approach 2:
Different regions of the battery module receive differentiated cooling treatment through the first and second cooling plates positioned on opposite sides. The electrode lead region, which generates significant heat, receives targeted cooling through the first cooling plate, while other regions are cooled by the second cooling plate, creating localized quality-based heat management that prevents hot spots during prolonged operation
