Title:
ABNORMAL BATTERY CELL IDENTIFICATION METHOD AND APPARATUS, ELECTRONIC DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/201531
Kind Code:
A1
Abstract:
The present application provides an abnormal battery cell identification method and apparatus, an electronic device, and a storage medium. The method comprises: determining, on the basis of target feature data of a battery cell, whether or not the battery cell is abnormal, wherein the target feature data comprises feature data generated during battery cell formation and used to distinguish an abnormal battery cell from a normal battery cell. In this way, on the one hand, since target feature data of an abnormal battery cell is distinctively different from target feature data of a normal battery cell during battery cell formation, it is possible to accurately determine whether or not the battery cell is abnormal. On the other hand, since battery cell formation necessarily takes place before battery cells are assembled into a battery pack during industrial production, an abnormal battery cell can be identified before the assembly, thereby reducing the risk of battery system performance deterioration and battery pack scrapping resulting from installing an abnormal battery cell.
