Integrated Battery Cell Supports for Portable Energy Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing energy storage products face issues with heavy weight and large volume due to fixed battery modules, leading to reduced portability and increased manufacturing costs, along with stress concentration risks from screw connections that can cause fractures under impact.
Innovation Solution
An energy storage power supply design incorporating a shell with integrated first and second supports that accommodate battery cells, allowing for reduced volume and weight, improved portability, and stress dispersion through the shell, while using busbars and acquisition boards for electrical connections and safety features like explosion-proof valves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If two battery supports are used to firmly assemble battery cells into a battery module, then the battery module can be stably held inside the shell, but the weight and volume of the energy storage product increase
Solution Approach 1:
The patent integrates the support function directly into the shell structure by providing first and second supports that are integral parts of the shell. This merging of the support function into the shell eliminates the need for separate battery supports, thereby reducing the overall weight and volume while maintaining stable holding of the battery module.
2Stability of the object's composition
If two battery supports are used to firmly assemble battery cells into a battery module, then the battery module can be stably held inside the shell, but the volume of the energy storage product increases
Solution Approach 1:
The support function is merged into the shell structure, eliminating separate support components and reducing the overall volume of the energy storage product while maintaining battery module stability.
3Stability of the object's composition
If the battery module is fixed inside the shell by a screw, then the battery module is securely attached, but stress concentration occurs at the fixed connection which may cause fracture under impact
Solution Approach 1:
The patent converts the potential harm of stress concentration into a beneficial distributed stress pattern. By using first and second supports with multiple first accommodation recesses and corresponding through holes, the attachment points are distributed across multiple locations, converting localized stress concentration into distributed stress that reduces fracture risk under impact.
4Stability of the object's composition
If the battery module is fixed inside the shell by a screw, then the battery module is securely attached, but the complexity of the device increases
Solution Approach 1:
The support function is merged into the shell structure, eliminating separate support components and simplifying the overall device complexity while maintaining secure attachment of the battery module.
