Battery Cell Pressing Module With Adjustable Link Gap Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cell pressing modules for secondary batteries face challenges in precisely adjusting the gap between pressing plates and efficiently replacing individual components, leading to increased maintenance time and potential damage during the charging and discharging process.
Innovation Solution
A cell pressing module with a link system that connects movement guiding units, allowing for adjustable separation distances and simple detachment/recombination, enabling precise gap control and easy replacement of pressing plates without disassembling the entire module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If chain members are fixed to pressing plates using pins, then the pressing plates are connected, but the gap between pressing plates cannot be precisely adjusted and separation/recombination is difficult
Solution Approach 1:
The chain member is divided into separate link units that can be independently attached and detached from pressing plates. Each link can be separately combined with or separated from individual pressing plates, enabling precise gap adjustment and easy maintenance operations without affecting the entire assembly.
2Reliability
If the entire cell pressing module is replaced, then component damage is addressed, but maintenance time increases
Solution Approach 1:
The cell pressing module is segmented into independently replaceable components including pressing plates, link members, and support frames. When damage occurs, only the specific damaged component needs to be replaced rather than the entire module, significantly reducing maintenance time while maintaining system reliability.
Solution Approach 2:
Damaged components such as pressing plates or link members can be discarded and replaced with new ones, while undamaged components are recovered and reused. This selective replacement approach minimizes waste and reduces maintenance time compared to replacing the entire module.
