Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-power battery modules with non-aqueous electrolytes have inefficient cell arrangement, leading to reduced accommodation efficiency due to unnecessary wide intervals between battery cells, which affects their use in high-power devices like electric vehicles.
Innovation Solution
A battery module design featuring a barrier with a partition wall and flange portions that cover and space battery cells, incorporating heat transfer medium flow paths and protrusions to optimize cell arrangement and reduce unnecessary space, along with a housing system to connect and secure the cells.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If battery cells are arranged with wide intervals between them, then safety and maintenance access are improved, but accommodation efficiency decreases
Solution Approach 1:
The barrier is segmented into a body portion and partition walls that extend between adjacent battery cells. This segmentation allows the barrier to provide safety isolation while minimizing the space required between cells, thereby improving accommodation efficiency without compromising safety.
Solution Approach 2:
The partition wall protrudes from the body portion in the direction extending between adjacent battery cells, utilizing the third dimension to provide safety isolation. This dimensional approach allows safety functionality to be achieved without increasing the planar spacing between cells, thus improving accommodation efficiency.
2Reliability
If unnecessary wide intervals are maintained between battery cells, then safety isolation is improved, but space utilization deteriorates
Solution Approach 1:
The barrier provides localized safety isolation through the partition wall that extends between adjacent battery cells. This local quality approach ensures safety isolation is provided only where needed between cells, rather than requiring uniform wide intervals throughout, thereby improving space utilization.
3Productivity
If battery cells are closely arranged, then accommodation efficiency is improved, but safety isolation deteriorates
Solution Approach 1:
The barrier acts as an intermediary structure between adjacent battery cells, providing safety isolation without requiring wide intervals. The partition wall extending between cells creates effective isolation while maintaining close arrangement, thus improving accommodation efficiency while preserving safety.
