Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current battery cell modules for motor vehicles require complex and costly manufacturing processes for securing and mounting, leading to tolerance issues and safety concerns due to high temperatures during welding and the need for multiple fastening elements, as well as separate housing components for protection.
Innovation Solution
A cooling plate designed as a mounting plate with integrated mounting elements that forms a closed-off space with a housing, allowing direct mounting and cooling of battery cells, eliminating the need for separate housing parts and reducing component count.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If laser welding and spot welding are used to secure battery cells, then mounting reliability is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The cooling plate is merged with mounting plate functions by integrating mounting elements directly into the cooling plate structure. This allows the cooling plate to simultaneously perform cooling and mounting functions, eliminating the need for separate mounting components and complex welding processes.
Solution Approach 2:
The cooling plate is designed as a multi-functional component that combines cooling function with mounting function. The mounting elements are integrated into the cooling plate, allowing it to serve both as a thermal management component and as a structural mounting component for battery cells.
2Manufacturing precision
If compression limiters with connecting rods are used during assembly, then battery cell positioning is improved, but tolerance problems occur during stacking
Solution Approach 1:
The mounting elements are integrated directly into the cooling plate structure, combining the positioning and securing functions into a single component. This eliminates the need for separate compression limiters and connecting rods, simplifying the assembly process while maintaining positioning accuracy.
3Reliability
If separate housing components are used to form closed-off space, then battery protection is improved, but device complexity and weight increase
Solution Approach 1:
The cooling plate is merged with the housing structure by integrating mounting elements and forming a closed-off space for battery accommodation. This eliminates the need for separate housing parts, reducing component count while maintaining protection functions.
Solution Approach 2:
The cooling plate serves multiple functions simultaneously: it provides cooling for the battery, forms a closed-off protective space, and acts as a mounting structure. This multi-functionality eliminates the need for separate components for each function.
