The abnormal state monitoring during the charging process of the electric vehicle is mainly the monitoring of the state of the electric vehicle power battery and the monitoring of the running state of the charging pile. In order to realize the safety of electric vehicle charging, this paper firstly clarifies the data mining process and its specific tasks in the process of electric vehicle charging status data processing. Based on data mining technology, a complete set of electric vehicle charging status data processing flow is established. The network established a data mining model of charging fault characteristics, and verified the model through the data of the charging process of electric vehicles on a certain day. safety, and promote the healthy development of electric vehicles.
