Title:
METHOD AND SYSTEM FOR PREDICTING REMAINING SERVICE LIFE OF LITHIUM BATTERY
Document Type and Number:
WIPO Patent Application WO/2022/257211
Kind Code:
A1
Abstract:
The present invention relates to the technical field of lithium batteries, and provides a method and system for predicting the remaining service life of a lithium battery. The method comprises: according to a historical battery capacity value of a lithium battery, obtaining a feature matrix of voltage, current and temperature data corresponding to each battery capacity value; considering the weight values of the voltage, current and temperature data and the effect of different feature types on the battery capacity values, combining feature matrices of the voltage, current and temperature data corresponding to the battery capacity values, and obtaining a measurement data feature matrix, a feature type matrix and a measurement data and feature type fusion matrix corresponding to different attention mechanisms; and splicing the measurement data feature matrix, the feature type matrix and the measurement data and feature type fusion matrix to obtain the predicted remaining service life of the lithium battery.
