Embodiment 1

[0099] See figure 2 , which is a schematic block diagram of a charging behavior identification method provided in an embodiment of the present application, and the method may include the following steps:

[0100] Step S201. Obtain the charging data of the electric vehicle uploaded by the charging pile, and the charging data includes charging current data.

[0101] It should be noted that the above charging data generally includes charging voltage data, charging current data and charging power data. In the charging process of electric vehicles, the charging voltage and charging power are generally constant, and the charging voltage and charging power contain less information than the charging current. In some cases, the charging behavior identification can be performed only based on the charging current data, and at this time, the above-mentioned charging data can only include the charging current data. In other cases, charging current data and charging voltage data are requ...

Embodiment 2

[0114] See Figure 4 , which is another schematic flowchart of a charging behavior recognition method provided in the embodiment of the present application, the method may include the following steps:

[0115] Step S401. Obtain the charging data of the electric vehicle uploaded by the charging pile, and the charging data includes charging current data.

[0116] Step S402, generating a charging current curve according to the charging current data.

[0117] Specifically, according to data such as charging current and voltage, corresponding curves are drawn in a set coordinate system.

[0118] It should be noted that, in general, charging data mainly includes current, voltage and power, while the charging power of electric vehicles is generally constant, and the power curve can play little role in the analysis and identification of battery status. Therefore, in some cases, only a current curve, or a current curve and a voltage curve, is required. In addition, the material type...

Embodiment 3

[0164] See Figure 9 , which is another schematic block diagram of the charging behavior identification method provided in the embodiment of the present application, the method may include the following steps:

[0165] Step S901. Obtain the charging data of the electric vehicle uploaded by the charging pile, and the charging data includes charging current data.

[0166]Step S902, input the charging data into the pre-trained random forest model, and obtain the charging mode corresponding to the charging data.

[0167] It should be noted that the random forest model can be a model including n decision trees, n is a positive integer greater than zero, and the model can be specifically Figure 10 The model in the random forest model diagram, such as Figure 10 As shown, it includes decision trees Tree1, Tree2...Tree(n-1), Tree(n), each decision tree classifies the corresponding random sample set, and obtains the corresponding classification results Type 1, Type 1...Type 2 , Typ...

Abstract

The embodiment of the invention is applicable to the technical field of electric vehicles, and discloses a charging behavior recognition method and device, terminal equipment and a computer readable storage medium, and the method comprises the steps: obtaining charging data, uploaded by a charging pile, of an electric vehicle, the charging data comprising charging current data; Judging whether thecharging current data meets a preset condition or not, the preset condition being that a time period in which the current continues to be a preset numerical value exists between the charging startingtime and the charging ending time, and the current difference between the current at the starting moment and the current at the ending moment of the time period is smaller than or equal to a preset current threshold; And when the charging current data meets a preset condition, determining that the behavior that the adapter is wrapped exists in the charging process. According to the embodiment ofthe invention, whether the charging behavior of wrapping the adapter exists in the charging process can be identified.

Description

technical field [0001] The present application belongs to the technical field of electric vehicles, and in particular relates to a charging behavior identification method, device, terminal equipment and computer-readable storage medium. Background technique [0002] With the continuous development of science and technology, the application of electric vehicles is becoming more and more extensive. [0003] At present, when a car owner uses a charging station to charge an electric vehicle, after completing the payment for the corresponding charging order, the corresponding socket of the charging pile will be powered on. The corresponding socket of the pile to charge the electric vehicle. [0004] In the charging process of electric vehicles, charging safety is very important, and the ventilation of the adapter is the basis for safe charging. However, some car owners use corresponding wrappings (for example, plastic bags) to wrap the adapter for some reason (for example, to p...
