Integrated Battery Module Bus Bar for Faster Pack Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly process of battery module assemblies is complex and time-consuming due to the use of separate bus bars and numerous parts, reducing workability and increasing manufacturing time.
Innovation Solution
The battery module is integrated with a bus bar that connects to neighboring modules, eliminating the need for separate bus bars and reducing the number of assembly parts and processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate bus bars are used for connecting battery modules, then electrical connection between modules is achieved, but assembly complexity and manufacturing time increase
Solution Approach 1:
The bus bar is integrated directly into the battery module structure, merging the electrical connection function with the module housing. This eliminates the need for separate bus bar components and their associated assembly steps, thereby reducing assembly complexity while maintaining reliable electrical connection between modules.
2Reliability
If separate bus bars with multiple parts are used, then electrical connection is established, but the number of parts and assembly time increase
Solution Approach 1:
The bus bar is merged into the battery module as an integrated component, eliminating the need for separate assembly steps. This reduces the number of parts and assembly operations required, directly decreasing assembly time while ensuring reliable electrical connection between adjacent modules.
