The invention provides a fault diagnosis method and device based on charging data, a medium and equipment. The method comprises the following steps: collecting charging data in a charging process; static features and time sequence features in the charging data are extracted; inputting the static features into a support vector machine model to obtain a first fault probability; inputting the time sequence features into a long short-term memory network to obtain a second fault probability; based on the first fault probability and the second fault probability, performing weighted summation to obtain comprehensive credibility; the method comprises the following steps of: collecting charging data in real time in a charging process, extracting static characteristics and time sequence characteristics in the charging data, and respectively identifying the static characteristics and the time sequence characteristics by using a support vector machine model and a long short-term memory network to obtain a first fault probability and a second fault probability; and integrating the first fault probability and the second fault probability to obtain the credibility of the charging fault so as to improve the accuracy of fault prediction.
