Battery Temperature Sensing Assembly for Snap-On Cell Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing temperature acquisition assemblies for batteries, particularly large cylindrical batteries, are cumbersome to dismount and mount, and the temperature measuring members often loosen or fall off due to limited mounting space caused by liquid cooling plates, making maintenance and replacement inconvenient.
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, which securely holds a temperature measuring member communicatively connected to a battery management system, facilitating quick dismounting and mounting, and using a sealant for enhanced protection and 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 measurement frame to provide stable temperature measurement while the tooling plate can be easily removed and reinstalled for maintenance, resolving the contradiction between measurement reliability and ease of maintenance.
2Reliability
If the temperature measuring member is bonded through thermally conductive adhesive, then thermal conduction is improved, but the replacement and maintenance process becomes time-consuming
Solution Approach 1:
By separating the measurement frame from the tooling plate, the patent enables quick replacement of the tooling plate without affecting the measurement frame's thermal conduction path. The measurement frame maintains reliable thermal contact with the cell, while the tooling plate can be rapidly swapped during maintenance, significantly reducing maintenance time while preserving thermal conduction reliability.
3Temperature
If liquid cooling plates are mounted on the cell, then cooling efficiency is improved, but the mounting space above the cell becomes limited
Solution Approach 1:
The measurement frame is designed to be mounted on the circumferential side surface of the cell rather than the top surface, utilizing the vertical/circumferential dimension. This dimensional change allows the temperature acquisition assembly to be installed in the available side space without interfering with the liquid cooling plates mounted on the top surface, thus maintaining cooling efficiency while finding a suitable mounting location.
