Battery Module End Plate Mounting for Better Space Utilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery modules suffer from inefficient space utilization due to the downward orientation of mounting holes, which leads to wasted space between the end plate and the battery cells.
Innovation Solution
The battery module incorporates a mounting hole at the lower side with an adjustable height mounting part, allowing for a mounting structure while providing additional space and enhancing space utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mounting holes are formed extending along the height direction at both ends of the end plate to fix the battery module, then the battery module can be securely fixed to the pack frame, but waste space occurs between the end plate and the battery cells, deteriorating space utilization
Solution Approach 1:
The mounting hole is repositioned from the end plate to the lower side of the battery module in the vertical dimension. This dimensional change allows the mounting structure to be formed without occupying horizontal space between the end plate and battery cells, thereby resolving the space utilization issue while maintaining fixing reliability
Solution Approach 2:
Instead of forming mounting holes at the upper end plate extending downward, the invention inverts the approach by forming the mounting hole at the lower side extending upward. This inversion eliminates the conflict with battery cell space while achieving the same fixing function
