Title:
SOC CALIBRATION METHOD, MODELING METHOD, MODELING APPARATUS, COMPUTER DEVICE AND MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/045790
Kind Code:
A1
Abstract:
An SOC calibration method, a modeling method, a modeling apparatus, a computer device and a medium. The modeling method comprises: extracting, on the basis of Internet of Vehicles data, historical vehicle data of vehicles of different models under different working conditions; processing abnormal data of the historical vehicle data to obtain a pre-processed data set (S2); performing label annotation and feature selection on data in the pre-processed data set, so as to obtain a training data set and a test data set (S3); and performing model training according to the training data set and the test data set, so as to establish an SOC calibration offline model (S4).
