Abstract

To address the problems of poor classification performance and low fault detection rate of machine models caused by the imbalance of electric vehicle fault data samples, this paper proposes a Bagging integrated electric vehicle fault prediction model with LightBDM as the base learner improvement based on the BS_Bagging-cLightGBM model. First, the training set is resampled using the Borderline_ SMOTE method in Bagging integrated learning to improve the degree of data imbalance in the training subset and avoid the missing information of small class samples; then, the weight coefficients and regularization terms are embedded in the loss function of the LightGBM base learner to improve the misclassification cost of small class samples in training; finally, we was evaluated and validated, and the experimental results showed that the BS_Bagging-cLightGBM model outperformed the single model in terms of accuracy, recall and F1-score metrics, and showed better prediction capability. The results of the study can provide an important reference for the repair and maintenance of electric vehicles.
