Battery Module Sealed Chamber Adhesive Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing battery modules face inefficiencies in cooling performance due to crossflow of coolant between chambers, which reduces the effectiveness of temperature regulation and leads to decreased cycle life of battery cells, as the clearance between battery cells and holders allows uncontrolled coolant flow.
Innovation Solution
Employing an adhesive material to both seal and fix battery cells within separate chambers, creating a sealed system that directs coolant flow along a predetermined path, thereby enhancing cooling performance and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If battery cells are held in place by a battery cell holder with apertures, then assembly is facilitated and cells are secured, but clearance between cells and holder causes crossflow of coolant reducing cooling performance
Solution Approach 1:
The invention extracts the sealing function from the mechanical holding structure by introducing a separate sealing element that fills the clearance gap between battery cells and holder, preventing coolant crossflow while maintaining the simple aperture-based holding structure for easy assembly
Solution Approach 2:
A sealing element is introduced as an intermediary component between the battery cells and the holder, filling the clearance gap to prevent coolant leakage while allowing the holder to maintain its simple aperture design for easy assembly and cell securing
2Reliability
If chambers are separated to direct coolant flow along a predetermined path, then cooling performance is optimized, but without proper sealing crossflow occurs between chambers deteriorating cooling performance
Solution Approach 1:
The sealing function is extracted from the chamber separation structure by using independent sealing elements positioned at the interfaces between chambers, allowing the separation structure to focus on directing coolant flow while the sealing elements prevent crossflow
3Productivity
If adhesive material is used to seal and fix battery cells, then both sealing and fixation are achieved in a single manufacturing step, but this combines multiple functions into one material application
Solution Approach 1:
The invention merges the sealing function and the fixation function into a single adhesive material application, allowing both functions to be achieved simultaneously in one manufacturing step, reducing production complexity and time
Solution Approach 2:
The adhesive material is designed to perform multiple functions simultaneously: it seals the clearance gap to prevent coolant crossflow and also mechanically fixes the battery cells to the holder, creating a multi-functional component that simplifies manufacturing
