Battery Module Side Connector Layout for Stable, Replaceable Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing energy storage devices face challenges during transportation due to the risk of damage from collisions or intensive displacement, leading to unnecessary waste and difficulty in replacing connectors or fasteners due to their heavy weight and cumbersome nature.
Innovation Solution
The energy storage device incorporates a box body, a battery module, and at least one connecting piece. The connecting piece is connected between the side surface of the battery module and the box body, facilitating the fixing and stability of the battery module, while its simple structure reduces production costs and allows for easier replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the battery module is fixed to the box body using traditional fasteners, then the connection strength is improved, but the weight and complexity of replacement increase
Solution Approach 1:
The connecting piece is designed as a separate, independent component that connects the battery module housing to the box body. This segmentation allows the connecting piece to be replaced independently without replacing the entire battery module or box body, significantly easing maintenance operations while maintaining connection strength through the dedicated connecting structure.
2Stability of the object's composition
If the connecting piece is positioned at the top and bottom of the battery module, then the structural stability is improved, but the ease of replacement and inspection deteriorates
Solution Approach 1:
The connecting piece is positioned at the side surface of the battery module housing rather than at the top and bottom, representing a dimensional change in the connection architecture. This side-surface positioning provides equivalent structural stability while dramatically improving accessibility for replacement and inspection operations, as the side surface is more accessible than the top and bottom surfaces.
3Reliability
If the connecting piece is designed with complex structure, then the connection reliability is improved, but the production cost increases
Solution Approach 1:
The connecting piece incorporates an integrated design where the connecting structure itself provides both the connection function and the mounting features. The connecting piece includes a connecting portion that connects to the battery module housing and a mounting portion that mounts to the box body, with mounting holes directly formed on the connecting piece. This self-service design eliminates the need for separate mounting brackets or additional fastening components, reducing production cost while maintaining connection reliability.

AI summary
An energy storage device and a control system for an energy storage device are provided. The energy storage device includes a case, a battery module, and at least one connecting piece. An accommodating cavity is defined in the case. At least one opening is formed on a side surface of the box body. The battery module is arranged in the accommodating cavity. The connecting piece is connected between a side surface of the battery module, for example, adjacent to the opening and the box body.
