Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery packs and modules face challenges in achieving a cost-effective, space-efficient, and robust configuration that is easily scalable, with prior solutions often requiring numerous parts and inadequate support and cooling mechanisms.
Innovation Solution
A battery module design featuring prismatic battery cells stacked with side terminals, supported by a cooling plate bottom member and beam members, connected by crossbeams, which also serve as a load-bearing structure, allowing for efficient cooling and support while minimizing part count.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate cooling plate and support structure are used, then cooling function is provided, but device complexity increases and space efficiency decreases
Solution Approach 1:
The patent combines the cooling plate and support structure into a single integrated component. The bottom plate serves dual functions: it provides structural support for the battery cells while simultaneously acting as a cooling plate with coolant channels, eliminating the need for separate cooling components and reducing overall device complexity
Solution Approach 2:
The bottom plate is designed as a multi-functional component that performs both mechanical support and thermal cooling functions. It supports the weight of stacked battery cells while containing coolant flow paths, making one component serve multiple purposes and reducing the total number of parts required
2Stability of the object's composition
If multiple separate components are used for support and cooling, then structural stability is improved, but manufacturing cost increases
Solution Approach 1:
The support structure and cooling plate are merged into a single integrated bottom plate component, reducing the number of parts that need to be manufactured and assembled. This integration simplifies manufacturing processes and reduces assembly steps while maintaining structural stability through the plate's rigid construction
3Volume of moving object
If battery cells are stacked in traditional configuration, then space utilization is achieved, but terminal accessibility is reduced
Solution Approach 1:
The patent utilizes side terminals on battery cells instead of traditional top/bottom terminals, changing the dimensional access point for electrical connections. This allows terminals to be accessed from the sides of stacked cells rather than requiring access to the top or bottom, improving accessibility while maintaining compact vertical stacking
