Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery module assembly through welding poses risks of heat damage and dirt accumulation, compromising the integrity and cleanliness of battery cells.
Innovation Solution
Implementing a non-welding method using male and female joining sections to connect exterior plates of the battery module, such as through crimping or deformation, to avoid these issues while maintaining structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If welding is used to join exterior plates, then structural strength is improved, but heat damage and dirt accumulation occur
Solution Approach 1:
The patent extracts the harmful welding process from the plate joining operation and replaces it with a non-welding mechanical joining method using male and female joining sections. This removes the source of heat damage and dirt accumulation while maintaining the structural connection function.
Solution Approach 2:
The patent replaces the thermal welding process with a mechanical joining system consisting of male and female joining sections that connect through deformation and interlocking. This substitution eliminates thermal effects while achieving structural strength through mechanical means.
2Reliability
If welding is used to join exterior plates, then connection reliability is improved, but cleanliness of battery cells deteriorates
Solution Approach 1:
The patent removes the welding process that generates spatter and dirt, replacing it with a mechanical joining method that does not produce contaminating byproducts, thereby maintaining connection reliability without compromising cell cleanliness.
Solution Approach 2:
The male and female joining sections are designed as dedicated mechanical connectors that perform the joining function without requiring expensive welding equipment or generating waste materials, providing a clean alternative to welding.

AI summary
In an embodiment, a battery module is configured for insertion into a battery module compartment of an energy storage system. The battery module includes a first exterior plate configured with a male joining section, a second exterior plate that is adjacent to the first exterior plate and configured with a female joining section, wherein the first and second exterior plates are joined together via the male and female joining sections without welding. In an example, by joining the first and second exterior plates (e.g., and optionally, other exterior plates of the battery module as well) without welding, problems associated with heat from a welding process as well as spatters and dirt accumulation at battery cells of the battery module can be reduced or avoided.
