Battery Cell Support Structure for Compact Energy Storage Packs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing energy storage power supplies have a large number of structural members, complex assembly processes, and low space utilization, leading to increased size and cost.
Innovation Solution
The energy storage power supply features a housing with an accommodation cavity containing cells, first and second supports with fixing members, and a busbar assembly for electrical connection, allowing direct cell mounting and reducing assembly processes while enhancing space utilization and fixing strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional assembly methods with multiple structural members are used, then structural strength is ensured, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent integrates multiple structural members into a single integrated support structure. The support structure includes mounting plates, support columns, and reinforcement ribs that are combined into one unified component, eliminating the need for separate structural members and reducing assembly complexity while maintaining structural strength
Solution Approach 2:
The integrated support structure serves multiple functions simultaneously: it provides structural support, mounts cells through fixing members, reinforces the housing, and facilitates assembly. This multi-functional design reduces the number of components needed while ensuring structural integrity
2Strength
If mounting space is reserved for structural members, then structural support is provided, but space utilization rate decreases
Solution Approach 1:
The fixing members are integrated within the support structure itself, with cell fixing members embedded in the mounting plates and support columns. This nested arrangement allows structural support and cell mounting functions to occupy the same spatial envelope, maximizing space utilization
3Reliability
If multiple assembly processes are used, then proper assembly is ensured, but productivity decreases
Solution Approach 1:
The integrated support structure is pre-assembled with fixing members, mounting plates, and support columns already positioned and secured together. This preliminary assembly reduces the number of steps required during final assembly, allowing cells to be directly mounted onto the pre-configured support structure without requiring multiple separate assembly operations
