Battery Pack End Plates with Integrated Guide Plates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery packs with multiple modules lack a stable and efficient method to connect and reinforce battery units, leading to potential structural instability and increased weight due to the need for additional connection frames.
Innovation Solution
A battery pack design featuring end plates with flanges and reinforcement plates that securely connect and support stacked battery modules, eliminating the need for external frames by using guide and insulation plates to maintain structural integrity and facilitate gas discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If additional connection frames are used to connect battery modules, then structural stability is improved, but weight increases
Solution Approach 1:
The connection frame is merged with the end plates by integrating guide plates and reinforcement plates directly into the end plate structure. The guide plates extend from the end plates to connect adjacent battery modules, eliminating the need for separate connection frames while maintaining structural stability.
Solution Approach 2:
The end plates are designed to serve multiple functions: they close the battery module containers, provide structural reinforcement through integrated guide plates for connecting adjacent modules, and include reinforcement plates for additional support. This multi-functionality eliminates the need for separate connection frames.
2Stability of the object's composition
If complex connection structures are used to secure battery modules, then structural integrity is improved, but manufacturing complexity increases
Solution Approach 1:
Multiple structural elements (end plates, guide plates, reinforcement plates) are merged into a single integrated component that can be manufactured as one piece. This reduces the number of separate parts that need to be manufactured and assembled, simplifying the manufacturing process while maintaining structural integrity.
Solution Approach 2:
The connection structure is segmented into functional zones within the single end plate component: guide plate regions for connecting adjacent modules, reinforcement plate regions for structural support, and base plate regions for closing the container. This segmentation of function within a unified structure simplifies manufacturing.
