Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery module temperature control systems are complex and inefficient in providing uniform temperature control across multiple battery cells, as they rely on passive and active cooling methods that do not effectively manage heat distribution and dissipation.
Innovation Solution
A battery module design featuring a housing with projections that form flow channels for temperature-control fluid, allowing direct contact between battery cells and projections, and connectors for fluid admission and discharge, ensuring uniform fluid distribution and flow paths that enhance temperature control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If passive and active cooling circuits are used to flow around individual battery cells, then temperature control is achieved, but the construction becomes complex and uniform temperature control is inefficient
Solution Approach 1:
The housing wall is segmented into multiple projections that individually contact each battery cell, creating separate flow channels for each cell. This segmentation allows independent temperature control for each cell while maintaining a unified housing structure, resolving the contradiction between uniform temperature control and system complexity
Solution Approach 2:
The cooling function is merged directly into the housing wall by forming projections as integral parts of the housing structure. This eliminates the need for separate cooling circuits and components, simplifying the overall construction while maintaining effective temperature control across all battery cells
2Ease of manufacture
If a simple housing structure is used, then manufacturing is easier, but reliable temperature control of multiple battery cells cannot be achieved
Solution Approach 1:
The housing wall incorporates segmented projections that directly contact each battery cell, creating individual flow channels. This segmentation enables reliable temperature control for each cell while maintaining a simple, integrated housing structure that is easy to manufacture
Solution Approach 2:
The housing wall itself provides the temperature control function through its integrated projections, eliminating the need for separate cooling systems. The structure serves dual purposes: housing the battery cells and providing active cooling, thereby simplifying manufacturing while ensuring reliable temperature control
