Battery Module Cooling Block for Electrode Lead Heat Dissipation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery modules experience localized temperature rises and increased temperature deviation due to the absence of cooling components at the electrode leads and busbars, leading to deteriorated performance.
Innovation Solution
Incorporation of a cooling block between electrode leads and end plates, coupled with a cooling pad and adhesive, to efficiently transfer heat away from these high-heat areas, along with a thermally conductive resin layer for overall heat dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cooling components are added at the electrode lead and busbar locations, then temperature deviation is reduced and cooling performance is improved, but device complexity increases
Solution Approach 1:
The cooling block is merged with the existing end plate structure, where the cooling block is disposed between the electrode leads and the end plate. This integration approach combines the cooling function with the structural end plate, reducing the need for separate cooling components and simplifying the overall device structure while maintaining improved cooling performance.
