Battery Module Assembly Guide for Connector Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing energy storage systems face issues with connector damage and detachment due to repeated demounting and mounting, affecting the stability and assembly convenience of secondary battery modules.
Innovation Solution
The energy storage system incorporates a first battery module assembly with a module guide and a second battery module assembly, featuring connectors that are spaced apart during pre-mounting to prevent collision, and a terminal insertion sequence that prioritizes high voltage terminals first to enhance stability and assembly convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If connectors are closely positioned for compact assembly, then assembly density is improved, but connector damage and detachment occur due to external forces and repeated demounting
Solution Approach 1:
The connector assembly is divided into separate components: a first connector on the first battery module assembly and a second connector on the second battery module assembly. These segmented connectors are positioned at different locations and connected through a controlled path, reducing the risk of mutual damage while maintaining compact overall assembly.
Solution Approach 2:
A guide structure acts as an intermediary between the two connectors, defining a specific insertion path and controlling the relative movement during assembly. This intermediary mechanism protects the connectors from external forces and misalignment damage while enabling compact positioning.
2Ease of operation
If demounting and mounting operations are performed frequently for maintenance, then ease of operation is improved, but connector damage and internal component detachment occur
Solution Approach 1:
The guide structure is pre-installed on the battery module assemblies before connector connection. This preliminary action establishes a protected insertion path that guides subsequent connector assembly and disassembly operations, preventing damage during repeated maintenance cycles while maintaining ease of operation.
3Stability of the object's composition
If module guide structure is added to guide mounting, then assembly stability is improved, but device complexity increases
Solution Approach 1:
The guide structure is merged with the battery module assembly housing rather than being a separate component. This integration provides assembly guidance and stability while minimizing the increase in device complexity, as the guide features are incorporated into the existing structural elements.
