Battery Cell Mounting Structure for Higher Pack Space Utilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in battery technology is to enhance both the structural strength and energy density of batteries while maximizing space utilization, as existing designs often compromise between these factors, with traditional methods using beams and side plates occupying internal space and affecting performance.
Innovation Solution
The solution involves a battery design where a spacer plate is connected to the first wall of each battery cell, eliminating the need for side plates and beams, and a mounting wall is connected to the second wall, allowing direct mounting and maximizing space utilization, thereby improving structural strength and energy density.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional beams and side plates are used to provide structural support, then structural strength is improved, but space utilization rate deteriorates
Solution Approach 1:
The patent combines the functions of side plates and beams into an integrated side plate structure with reinforcing ribs. The side plate serves both as a mounting surface for battery cells and as a structural reinforcement element, eliminating the need for separate beam structures and maximizing internal space utilization while maintaining structural strength.
Solution Approach 2:
The side plate is segmented into multiple regions including mounting areas for battery cells and reinforcing rib structures. This segmentation allows the side plate to provide localized structural support where needed while minimizing overall material usage and maximizing the available space for battery cells.
2Ease of operation
If space is reserved between mounting wall and battery cell for electrode terminal, then ease of operation is improved, but space utilization rate deteriorates
Solution Approach 1:
The patent positions the electrode terminal on the third wall of the battery cell rather than on the second wall that interfaces with the mounting wall. This dimensional repositioning allows the battery cell to be directly mounted against the mounting wall without requiring clearance space, as the electrode terminal protrudes from a different face of the cell.
3Reliability
If more structural components are added to enhance battery performance, then reliability is improved, but device complexity deteriorates
Solution Approach 1:
The side plate is designed to perform multiple functions simultaneously: it serves as a mounting structure for battery cells, provides structural reinforcement through integrated ribs, and facilitates thermal management. This multi-functionality reduces the need for separate components and simplifies the overall battery structure while maintaining or enhancing performance.
