Adjustable Battery Cell Test Probe Spacing for OCV Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery cell OCV test technologies face inefficiencies when testing battery cells of different dimensions, as they struggle to quickly adapt to varying electrode terminal spacings.
Innovation Solution
A battery cell testing probe mechanism is designed with a connecting member and multiple test members, where at least one test member is slidably connected to the connecting member, allowing for adjustable spacings between test members to accommodate different battery cell dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If battery cells of different dimensions are tested using a fixed probe mechanism, then the testing process remains simple, but the testing efficiency decreases due to inability to quickly adapt to varying electrode terminal spacings
Solution Approach 1:
The probe mechanism incorporates adjustable test members that can be moved along the connecting member to change spacing between probes. This dynamic adjustment capability allows the mechanism to adapt to different battery cell dimensions and electrode terminal spacings, thereby improving testing efficiency without requiring complete replacement of the probe mechanism.
Solution Approach 2:
The probe mechanism is divided into a connecting member and multiple independently adjustable test members. Each test member can be adjusted separately to match the specific spacing requirements of different battery cells, enabling flexible adaptation while maintaining overall structural simplicity.
2Adaptability or versatility
If the spacing between test members is fixed, then the structure remains simple, but the adaptability to different battery cell dimensions is poor
Solution Approach 1:
The test members are designed with adjustable positioning capabilities, allowing them to be moved to different locations along the connecting member. This dynamic adjustment enables the probe mechanism to adapt to various battery cell dimensions and electrode terminal spacings while maintaining a relatively simple overall structure.
Solution Approach 2:
The probe mechanism is designed to test multiple types of battery cells with different dimensions by adjusting the spacing between test members. A single probe mechanism can serve multiple testing purposes across different battery cell specifications, improving versatility without requiring multiple dedicated probe mechanisms.

AI summary
This application provides a battery cell testing probe mechanism (100), a testing apparatus (1000), and a battery production line (10000). The battery cell testing probe mechanism (100) includes a connecting member (10) and multiple test members (20). The connecting member (10) is configured to connect to an external structure, and at least one test member (20) is slidably connected to the connecting member (10) along a first direction X. Each test member (20) corresponds to an electrode terminal (4001) of a battery cell (4000) and performs relevant data collection on the corresponding electrode terminal (4001). When battery cells (4000) of different dimensions are tested, one or more test members (20) can be moved relative to the connecting member (10) along the first direction X to adjust spacings between the test members (20), thereby meeting the testing requirements for the spacing between electrode terminals (4001) of battery cells (4000) of different dimensions and improving testing efficiency.
