[0041] Currently, charging stations are unable to obtain charging data of electric vehicles during the charging process, resulting in the inability to monitor abnormal conditions of electric vehicles during the charging process.

[0050] S2: Correcting the temperature field data based on the property information of the battery to obtain corrected temperature field data.

[0051] S3: Determine whether the battery is currently abnormal based on the corrected temperature field data.

[0052] In the technical solution of the embodiment of the present application, the temperature field data of the battery at the current moment is corrected by obtaining the battery's attribute information, thereby reducing the impact of the battery's attribute information on the accuracy of the temperature field data, improving the accuracy of the battery's temperature field data, and thereby improving the accuracy of the battery's abnormal state detection.

[0053] Specifically, the temperature field data of the vehicle is obtained by scanning the electric vehicle using a three-dimensional thermal imaging technology. In one embodiment, the temperature field data of the vehicle is obtained by scanning the electric vehicle using a three-dimensional thermal imaging device. A three-dimensional coordinate system of the vehicle is established, and the temperature field data collected by the three-dimensional thermal imaging device is recorded as T (x,y,z) The temperature field data is a temperature data set composed of temperature data at various locations of the vehicle.

[0054] In order to facilitate the detection of the positions of various parts of the electric vehicle and reduce data collection errors, the installation position of the three-dimensional thermal imaging device is set according to the installation position of the battery in the electric vehicle.

[0055] In one embodiment, when the battery is installed on the bottom of the vehicle, the 3D thermal imaging device is mounted on the ground or placed in a groove in the ground to provide more accurate temperature data collected by the 3D thermal imaging device. Because batteries occupy a large volume in electric vehicles, they are typically placed in a pre-defined area on the bottom of the vehicle. In one embodiment, the battery is located between the four wheels of the vehicle.

[0056] In one embodiment, after obtaining the temperature field data of the vehicle, the temperature field data corresponding to the preset area is extracted from the temperature field data of the vehicle as the temperature field data T of the battery. r(x,y,z) .

[0057] In one embodiment, the temperature field data of a preset area of ​​the vehicle is directly collected by a three-dimensional thermal imaging device as the temperature field data T of the battery. r(x,y,z) .

The scanning distance range is 54cm-60cm. In this embodiment, the data collection for the battery is contactless and does not affect the electric vehicle.

[0060] In the technical solution of the embodiment of the present application, the temperature field data of the battery collected at the current moment is corrected by the battery model, the ambient temperature of the battery, and the scanning distance when collecting the temperature field data of the battery. The error caused by the battery model, ambient temperature and scanning distance to the temperature field data is corrected, thereby improving the accuracy of the temperature field data collected at the current moment.

Specifically, a 18650 battery at an ambient temperature of -10 degrees Celsius is scanned using a three-dimensional thermal imaging device at a distance of 20 cm from the battery to obtain an initial temperature field of the battery sample. Temperature sensors disposed at multiple locations within the battery are used to detect the actual temperature field of the battery. The value obtained by subtracting the initial temperature field from the actual temperature field is used as a preset error value corresponding to the preset attribute information.

[0065] The preset error values ​​corresponding to other preset attribute information can be obtained through the above method.

[0066] In the technical solution of the embodiment of the present application, the temperature field data of battery samples with different attribute information are detected, and the difference between the detected temperature field and the actual temperature field is used as the error value corresponding to the attribute information.

[0067] In some embodiments, based on the comparison between the battery's attribute information and the preset attribute information, the preset error value corresponding to the preset attribute information that matches the battery's attribute information is determined as the battery's error information; based on the battery's error information and the battery's temperature field data, the battery's corrected temperature field data is determined.

[0068] The temperature field data collected at the current moment of the battery is corrected through the battery error information, thereby reducing the inaccuracy of the battery temperature information caused by external factors or the battery's own properties and improving the detection accuracy of the temperature field data.

[0069] In the technical solution of the embodiment of the present application, by comparing the attribute information of the battery with the preset attribute information, the error information corresponding to the attribute information can be quickly obtained, and the temperature field data collected at the current moment is corrected by the error information to obtain the true temperature field of the battery at the current moment, thereby improving the detection accuracy of the temperature field data.

[0072] In some embodiments, in response to the temperature change rate of the battery at the current moment exceeding the warning value, it is determined that the battery is in an abnormal state at the current moment; the charging device is controlled to stop charging the battery and issue an alarm.

[0073] In some embodiments, in response to the temperature change rate of the battery at the current moment not exceeding the warning value, it is determined that the battery is in a normal state at the current moment; and the charging device is controlled to continue charging the battery.

[0074] In the technical solution of the embodiment of the present application, if the temperature change rate of the battery at the current moment exceeds the warning value, it indicates that the temperature change rate of the battery at the current moment is abnormal and there is a risk of fire.
