Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If thermal management components are added to ensure thermal management, then thermal management performance is improved, but space utilization rate decreases and energy density is reduced
Solution Approach 1:
The thermal management component is integrated with the battery cell structure by connecting to the first wall (largest surface area wall) of each battery cell. The heat conducting plates are positioned to directly contact or closely approach the battery cell walls, merging the thermal management function with the existing battery structure rather than adding separate external components.
Solution Approach 2:
The thermal management component utilizes the space along the thickness direction (second direction) of the battery cell by positioning heat conducting plates at both sides of the flow passage. This three-dimensional arrangement allows thermal management functionality to be embedded within the available spatial dimensions without significantly increasing the overall battery footprint.
2Temperature
If thermal management components are added to ensure thermal management, then thermal management performance is improved, but the structure becomes more complex
Solution Approach 1:
The thermal management component is divided into distinct functional segments: heat conducting plates for thermal conduction, flow passages for fluid circulation, and connection structures for attaching to battery cells. This segmentation allows each component to be optimized independently and simplifies the overall assembly process.
Solution Approach 2:
The thermal management component serves multiple functions simultaneously: the heat conducting plates conduct heat away from battery cells, the flow passages provide fluid circulation pathways, and the overall structure acts as a structural support element within the battery assembly. This multi-functionality reduces the need for additional separate components.
3Temperature
If the thickness of heat conducting plate is increased to improve thermal conduction, then thermal conduction performance is improved, but space utilization rate decreases
Solution Approach 1:
The thickness of the heat conducting plate is optimized within a specific range (0.01≤D/H≤25 where D is plate thickness and H is flow passage size) to achieve the desired thermal conduction performance while minimizing space occupation. This parameter optimization balances thermal conductivity requirements with spatial constraints.
