Conventional battery modules face challenges in forming and changing heat transfer paths, require increased work and time for assembly, and have high manufacturing costs due to complex cooling structures.
Innovation Solution
A battery module with a porous cooling/buffering member beneath the battery cell laminate, featuring a truss structure or spring arrangement, supports the load and facilitates heat emission, allowing for easy formation of heat transfer paths and enhancing structural stability while reducing the number of components and manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a conventional cooling plate structure is used, then heat can be emitted from the battery cells, but the heat transfer path is difficult to form and change, and manufacturing complexity increases
Solution Approach 1:
The patent combines the cooling function with the buffer member into a single integrated component. The porous buffer member serves both as a mechanical buffer to absorb expansion forces and as a heat transfer medium through which coolant flows, eliminating the need for separate cooling plates and reducing structural complexity while maintaining effective heat emission from battery cells
Solution Approach 2:
The buffer member is designed to perform multiple functions simultaneously: mechanical buffering against expansion, heat conduction from battery cells, and coolant flow channel provision. This multi-functional design simplifies the overall cooling system structure while maintaining effective temperature control
2Stability of the object's composition
If multiple separate components (cartridge, cell cover, cooling plate) are bound to battery cells, then structural stability is improved, but work requirements and assembly time increase
Solution Approach 1:
The patent merges the cartridge, cell cover, and cooling plate into a single integrated housing structure that encloses the battery cells. This unified structure provides the necessary structural stability while significantly reducing the number of assembly steps and binding operations required compared to conventional multi-component designs
3Temperature
If a conventional cooling plate is mounted beneath battery cells, then heat transfer is achieved, but the number of components and manufacturing costs increase
Solution Approach 1:
The cooling function is integrated into the buffer member itself, which is already required for mechanical support and expansion accommodation. By incorporating coolant flow channels within the porous buffer structure, the patent eliminates the need for separate cooling plates, reducing component count, assembly complexity, and manufacturing costs while maintaining effective heat transfer from battery cells
