The invention discloses an electric vehicle battery abnormality detection method and device, intelligent equipment and a storage medium. The method comprises the steps of obtaining charging current data of an electric vehicle; determining whether the charging current data has preset charging curve characteristics including that the occurrence frequency of the current change points is greater thana preset frequency, the absolute value of the current difference between the first reporting time point and the second reporting time point is greater than or equal to a preset current threshold, andthe time length between the adjacent current change points is less than or equal to a preset time length threshold; and if the charging current data does not have the preset charging curve characteristics, judging that the battery of the electric vehicle is abnormal. The method can achieve the detection of the abnormality of the battery of the electric vehicle, can timely know whether the batteryof the electric vehicle is abnormal or not, can reduce the potential safety hazards in a charging process, and improves the safety of the charging process of the electric vehicle.
Description
technical field [0001] The present application belongs to the technical field of electric vehicles, and in particular relates to a method, device, intelligent device and storage medium for detecting abnormality of an electric vehicle battery. Background technique [0002] With the continuous development and progress of society, the application of electric vehicles is becoming more and more extensive. In the field of transportation, the electrification of vehicles has gradually become a trend. At present, electric vehicle users can use the charging pile of the charging station to charge the electric vehicle. After completing the corresponding charging order payment, the corresponding socket of the charging pile will be powered on. At this time, the electric vehicle user can use the electric vehicle adapter, charging Connect the electric vehicle to the corresponding socket of the charging pile to charge the electric vehicle. [0003] During the charging process of electric v...
