Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing temperature acquisition assemblies in large cylindrical batteries are cumbersome to dismount and mount, prone to loosening, and inconvenient to maintain due to the limited mounting space caused by liquid cooling plates, which complicates the replacement of temperature measuring members.
Innovation Solution
A temperature acquisition assembly with a measurement frame mounted on the cell's circumferential side surface in a snap manner, featuring a detachable tooling plate and electrical connection member, allowing quick dismounting and mounting of the temperature measuring member, secured by a sealant and flexible electrical connection, and enhanced by snap fittings and stiffeners for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the temperature measuring member is adhesively mounted on the cell through thermally conductive adhesive, then the temperature measurement function is achieved, but the dismounting and mounting process becomes cumbersome and maintenance becomes inconvenient
Solution Approach 1:
The temperature acquisition assembly is divided into separate components: a measurement frame that remains fixed on the cell, and a tooling plate with the temperature measuring member that can be detached. This segmentation allows the measuring member to be easily removed and replaced without affecting the mounted structure, solving the cumbersome dismounting issue while maintaining measurement reliability.
Solution Approach 2:
The invention transitions from a static adhesive bonding method to a dynamic detachable connection method. The tooling plate can be freely assembled and disassembled from the measurement frame through snap-fit structures, enabling quick maintenance and replacement operations while ensuring stable temperature measurement during operation.
2Measurement precision
If the temperature measuring member is bonded through thermally conductive adhesive, then thermal conduction is achieved, but the replacement and maintenance process becomes time-consuming
Solution Approach 1:
The measurement frame is pre-mounted on the cell with proper thermal contact structures in advance. The tooling plate with the temperature measuring member is designed with pre-integrated electrical connection members and snap-fit structures. This preliminary preparation allows for rapid replacement during maintenance without time-consuming reinstallation procedures, while ensuring consistent thermal and electrical contact for precise measurements.
3Temperature
If liquid cooling plates are mounted on the cell, then cooling function is achieved, but the mounting space above the cell becomes limited
Solution Approach 1:
Instead of mounting the temperature acquisition assembly on the limited upper surface of the cell, the invention utilizes the circumferential side surface of the cell for mounting the measurement frame. This dimensional transition from vertical mounting to lateral mounting opens up additional space around the cell, allowing the temperature measurement function to be implemented without interfering with the liquid cooling plates positioned on the upper surface.
