Title:
BATTERY CELL PROCESS DATA ANALYSIS SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2023/182860
Kind Code:
A1
Abstract:
A battery cell process data analysis system according to an embodiment comprises: a process data acquisition unit for acquiring process data of a battery cell; a predicted capacity estimation unit for estimating a predicted capacity of the battery cell on the basis of the process data; an actual capacity measurement unit for measuring an actual capacity of the battery cell; and a controller for calculating a difference between the predicted capacity of the battery cell and the actual capacity of the battery cell, and determining a process factor affecting the difference in capacity by using a trained artificial intelligence model.
