I-Shaped Battery Housing Support for Pouch Cell Rigidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing battery pack housing design lacks rigidity due to unsupported battery cells, leading to deformation and performance issues, and has cumbersome assembly processes.
Innovation Solution
An I-shaped support structure is integrated into the battery housing, omitting upper and lower cover plates, which provides internal support and improves rigidity, facilitating easier assembly by forming accommodation cavities for battery cells and enhancing explosion-proof performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional housing design with upper and lower cover plates is used, then the housing structure is complete, but the assembly process is cumbersome and the overall rigidity is poor
Solution Approach 1:
The patent merges the support structure and housing into a single integrated component. The housing is designed with an I-shaped cross-section where the web portion serves as the support structure, eliminating the need for separate upper and lower cover plates. This integration simplifies the assembly process while maintaining structural rigidity through the optimized I-shaped design.
Solution Approach 2:
The housing is segmented into functional regions: the web portion provides support structure, while the flanges form the housing walls. This segmentation allows each part to perform its specific function optimally - the web for structural support and rigidity, and the flanges for housing functionality - while being manufactured as a single integrated piece.
2Device complexity
If battery cells are stacked without internal support, then the housing structure is simpler, but the battery cells are easily deformed by force
Solution Approach 1:
The support structure is merged with the housing structure itself. The I-shaped cross-section of the housing provides internal support for the stacked battery cells without requiring separate support components. The web portion of the I-shaped housing acts as the support structure, while the flanges provide the housing walls, achieving both support and housing functions in one integrated component.
3Strength
If multiple separate components are used for housing, then the structure may be more robust, but the assembly becomes cumbersome and troublesome
Solution Approach 1:
The patent combines multiple housing components (upper cover plate, lower cover plate, and support structure) into a single integrated housing with an I-shaped cross-section. This eliminates the need for separate assembly of multiple parts while maintaining structural robustness through the optimized I-shaped design where the web provides support and the flanges provide housing walls.

AI summary
A support, a housing and a pouch battery module is provided. A cross-section of the support is I-shaped, wherein the support includes an upper flat part, a lower flat part and a connecting part, and the upper flat part is configured to be used as an upper cover plate of the housing of the battery. The lower flat part is arranged in parallel with the upper flat part, and the lower flat part is configured to be used as the lower cover plate of the housing of the battery. Two ends of the connecting part are respectively fixedly connected to the upper flat part and the lower flat part.
