Title:
ELECTRONIC DEVICE FOR DETECTING BATTERY ABNORMALITY, AND METHOD FOR OPERATING SAME
Document Type and Number:
WIPO Patent Application WO/2024/053870
Kind Code:
A1
Abstract:
An electronic device according to one embodiment disclosed herein can: obtain input data through a detection circuit; obtain normalized data for the input data by normalizing each of column vectors of the input data; obtain determination standard data on the basis of the normalized data; and determine whether each of M battery cells has a first state abnormality and/or a second state abnormality on the basis of values indicated by respective entries of row vectors of the determination standard data. The presence of the first state abnormality can be determined on the basis of a learning-based model, and the presence of the second state abnormality can be determined on the basis of a method other than the learning-based model.
