Battery Module Clamp for Cell Replacement Without Compression Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When a cell in a battery module fails, the compression between cells is lost upon removing the rods, necessitating the replacement of the entire battery module.
Innovation Solution
A clamp system with a body, arm, and jaws that can move linearly to compress and hold a section of the battery module, allowing for maintenance or replacement of cells without losing compression across the module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If rods are removed to replace cells in a battery module, then cell replacement is enabled, but compression between cells is lost requiring full module replacement
Solution Approach 1:
The battery module is divided into multiple sections that can be independently serviced. Each section can be accessed and repaired without affecting other sections, enabling localized maintenance while preserving the overall module structure and compression integrity.
Solution Approach 2:
A compression maintenance device serves as an intermediary mechanism that preserves compression forces during cell replacement operations. This device allows technicians to remove and replace cells while maintaining the necessary compression between cells, preventing the need for full module replacement.
2Reliability
If the entire battery module is replaced when a cell fails, then compression is maintained, but resource waste and cost increase
Solution Approach 1:
The faulty cell is extracted from the battery module for replacement, while the rest of the module is preserved. This selective removal and replacement approach allows maintenance of individual cells without discarding the entire module, reducing resource waste and replacement costs.
Solution Approach 2:
Instead of discarding the entire battery module when a cell fails, the system recovers and reuses the functional sections. The compression maintenance device enables recovery of the module structure and functional cells, discarding only the defective component.
3Reliability
If rods extend through all sections to maintain compression, then compression is preserved, but access to individual sections is blocked
Solution Approach 1:
The battery module is segmented into multiple independent sections with individual access points. This segmentation allows compression to be maintained through the overall structure while enabling easy access to specific sections for maintenance without requiring removal of rods from all sections.
Solution Approach 2:
The compression maintenance device acts as an intermediary that temporarily assumes the compression function during rod removal operations. This allows sections to be accessed and serviced while compression forces are preserved through the intermediary device, then transferred back to the rod system.

AI summary
A clamp is configured for compressing a section of a battery module. The clamp includes a body, an arm, a first jaw, and a second jaw. The first jaw is operatively connected to the body. The arm is operatively connected to the body. The second jaw is operatively connected to the arm. Each jaw is con figured to engage opposing ends of the battery module. The arm is slidably attached to the body to allow linear movement of the arm relative to the body along an axis. The second jaw moves with the arm a clamping distance between an extended position, for releasing the section of the battery module, and a compressed position, for holding the section of the battery module in compression between the jaws.
