Title:
VIBRATION TEST JIG AND VIBRATION TEST APPARATUS FOR CYLINDRICAL BATTERY CELL
Document Type and Number:
WIPO Patent Application WO/2021/112430
Kind Code:
A1
Abstract:
The present invention relates to a vibration test jig for a cylindrical battery cell, comprising: a main body for accommodating a cylindrical battery cell; and a connection unit electrically connected to an electrode terminal of the cylindrical battery cell, wherein the connection unit comprises: a connection member electrically connected to the electrode terminal and withdrawn to the outside of the main body; a support member for supporting the connection member; and a fixing member for fixing the support member on the main body. The vibration test jig of the present invention enables the cylindrical battery cell mounted in the jig to be electrically connected to an external voltage and resistance measuring device through the connection unit, and thus, during a vibration test, an electrical state of the battery cell can be monitored in real time, and it can be checked whether and when an electrode tab is disconnected by using the measured voltage or resistance value.
