Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery modules face challenges in providing a compact and stable configuration for high-output battery cells, particularly in devices requiring high power, such as electric cars, where the varying sizes and shapes of devices necessitate a flexible and lightweight battery module design.
Innovation Solution
A battery module design featuring at least two battery cells with face-to-face back surfaces, a mid-support system including base and flange portions, and a housing with end plates and a cover plate, which securely fixes the cells together using fasteners and fixing tabs, allowing for efficient stacking and secure positioning of the cells.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If battery cells are connected in series to form a high-output battery module, then power output is improved, but the size and weight of the battery module increase
Solution Approach 1:
The battery module is divided into multiple sub-modules, each containing a specific number of battery cells connected in series. This segmentation allows the overall power output to be achieved through parallel connection of sub-modules while keeping each sub-module compact and lightweight, thus resolving the contradiction between power output and weight.
2Power
If battery cells are connected in series to form a high-output battery module, then power output is improved, but the volume of the battery module increases
Solution Approach 1:
The battery module is divided into multiple sub-modules, each containing a specific number of battery cells connected in series. This segmentation allows the overall power output to be achieved through parallel connection of sub-modules while keeping each sub-module compact and space-efficient, thus resolving the contradiction between power output and volume.
Solution Approach 2:
The battery cells are arranged in a nested configuration where multiple cells are stacked or positioned within a compact housing structure. This nesting approach maximizes the use of internal space, allowing high-power battery cells to be packed efficiently without excessive volume increase, thereby resolving the contradiction between power output and volume.
3Volume of stationary object
If a compact battery module design is implemented, then volume is reduced, but structural stability may deteriorate
Solution Approach 1:
The housing structure employs an asymmetric design with strategically positioned support ribs and reinforcement elements that provide optimal structural stability for the compact configuration. The asymmetric reinforcement is concentrated in areas experiencing highest stress, allowing volume reduction while maintaining stability.
Solution Approach 2:
The housing is pre-designed with integrated support structures and reinforcement elements built into the compact form factor. These preliminary structural provisions ensure that even in the reduced-volume configuration, the battery module maintains adequate structural stability without requiring additional external support.
