Abstract
Provided is a battery management method and apparatus. The battery management method includes acquiring physical quantity data, for each of a plurality of batteries, of when corresponding physical quantities of the plurality of batteries, making up the physical quantity data, dynamically vary, calculating unbalance data based on physical quantity difference information derived from the physical quantity data, calculating feature data for the physical quantity data by projecting the unbalance data to a feature space, and determining a battery safety for one or more of the plurality of batteries based on determined distribution information of the feature data.
Claims10
A battery management method comprising:
- determining unbalance data based on physical quantity difference information of a plurality of batteries, wherein the physical quantity difference information is derived based on sensing data of each of the batteries;
- extracting feature data from the unbalance data using a feature extraction model;
- estimating a similarity between distribution information of the extracted feature data and distribution information of normal feature data;
- and
- determining a battery state based on the estimated similarity.
A battery management apparatus comprising:
- one or more processors configured to:
- determine unbalance data based on physical quantity difference information of a plurality of batteries, wherein the physical quantity difference information is derived based on sensing data of each of the batteries,
- extracte feature data from the unbalance data using a feature extraction model,
- estimate a similarity between distribution information of the extracted feature data and distribution information of normal feature data, and
