Abstract

The present application discloses a method, device, intelligent device and storage medium for detecting battery abnormality of an electric vehicle. The method includes: acquiring charging current data of the electric vehicle; It is assumed that the characteristics of the charging curve include that the number of occurrences of current change points is greater than the preset number of times, 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 the preset current threshold, and the adjacent current change points The length of time between is less than or equal to a preset duration threshold; if the charging current data does not have the characteristics of the preset charging curve, it is determined that the battery of the electric vehicle is abnormal. The application can realize the detection of the abnormality of the battery of the electric vehicle, and can know in time whether there is an abnormality in the battery of the electric vehicle, thereby reducing the potential safety hazard in the charging process and improving 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...
