U-Shaped Battery Cell Module Assembly With Integrated Busbar Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cell module assemblies require a complex assembly process involving sequential stacking of battery cells, cartridges, and busbar units, which can be time-consuming and prone to errors.
Innovation Solution
A cell module assembly design where the busbar unit is integrally coupled to a U-shaped case, with slits for electrode leads and a bent frame to facilitate easy insertion of battery cells, and side walls for guidance, allowing for simplified assembly and inspection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If battery cells, cartridges, and busbar units are sequentially stacked and assembled, then the cell module assembly can be formed with functional components in place, but the assembly process becomes complicated and time-consuming
Solution Approach 1:
The busbar unit is integrally coupled to the case as a single pre-assembled component, merging the busbar unit and case into one structural unit. This eliminates the need for separate assembly steps of stacking cells and cartridges, then separately coupling the busbar unit, thereby simplifying the overall assembly process while maintaining functional integrity
2Reliability
If battery cells, cartridges, and busbar units are sequentially stacked and assembled, then the cell module assembly can be formed with functional components in place, but the assembly time increases considerably
Solution Approach 1:
The busbar unit is pre-coupled to the case before battery cells are inserted. This preliminary action of integrating the busbar unit with the case structure allows for faster final assembly, as the structural framework and electrical connection components are already in position, eliminating time-consuming sequential stacking operations
3Reliability
If the cell module assembly is wrongly assembled using sequential stacking, then assembly errors occur, but it takes considerable time to reassemble
Solution Approach 1:
By integrating the busbar unit with the case as a single pre-assembled component, the invention reduces the number of discrete assembly steps. This integration minimizes opportunities for assembly errors and simplifies reassembly, as fewer components need to be manually positioned and aligned, thereby reducing both error rates and reassembly time
