Abstract

A method of battery capacity estimation including: obtaining a charging current, charging voltage, charging time, and charging voltage interval of a battery being estimated; determining a charging current interval and a charging time interval based on the charging current, the charging voltage, and the charging time, where the charging current interval and the charging time interval correspond to the charging voltage interval; obtaining training features for model training, where the training features include training electrochemical features and training time domain features; determining actual features of the battery being estimated based on the charging voltage interval, the charging current interval, the charging time interval, and the training features, where the actual features include actual electrochemical features and actual time domain features; and estimating, based on the model and the actual features, an actual capacity of the battery being estimated.
