Initially, the paper models the DC charging station charging modules.
After obtaining current data, it uses wavelet packet decomposition to extract feature vectors to form a dataset, which is then used to train the constructed CNN network model. Simulation verification demonstrates the superiority of the CNN model in identifying faults in DC charging station charging modules.
