description The invention discloses a power battery charging fault identification and early warning method, system and device and a medium, and the method comprises the steps: collecting battery parameters, and carrying out the preprocessing of the battery parameter data; extracting features of the preprocessed battery parameters; clustering the characteristics of the preprocessed battery parameters to obtain a clustering result; according to the clustering result, obtaining a standard charging feature; carrying out feature matching on the standard charging feature and the real-time charging feature, and carrying out fault identification and fault alarm according to a matching result; the charging safety margin is calculated in real time, whether the charging safety margin exceeds a threshold value or not is judged, and early warning is given out according to the judgment result. According to the invention, through the synergistic effect of the calibration features, the real-time diagnosis and the long-term early warning
