Title:
SYSTEM FOR ASSESSMENT OF BATTERY CELL DIMENSIONAL VARIATION
Document Type and Number:
WIPO Patent Application WO/2023/178020
Kind Code:
A3
Abstract:
A system for assessment of dimensional variation of an electro-chemical battery cell during charge/discharge cycling, including a test fixture configured to position thereon a battery cell. The test fixture includes a pressure plate configured to apply a force to the battery cell. The test fixture also includes a reaction plate disposed parallel to the pressure plate and configured to sandwich the battery cell between the reaction plate and the pressure plate. The test fixture additionally includes an elastic member assembly configured to facilitate adjustment of the force applied to the battery cell. The system additionally includes an electronic hardware device configured to regulate an electrical current applied to the battery cell. The system further includes a contact displacement sensor configured to detect change in the battery thickness.
