Embodiment 1

[0041] When in use, install two infrared thermal imaging cameras on the vertical line of the diagonal line of the lithium-ion battery pack body, and the distance from the diagonal line of the battery pack body to be monitored is 70mm. The included angle is 30°, and an infrared thermal imager is installed on both sides of the body diagonal.

[0042] Assuming that a 18650 lithium-ion battery pack undergoes a discharge reaction within the monitoring range of an infrared thermal imaging camera, and the current temperature is abnormal, the early warning method includes the following steps:

[0043] 1) After the infrared thermal imaging camera obtains the infrared image of the battery pack, it feeds back the image to the computer 6 in real time, and analyzes it by the computer software module to obtain the highest temperature in the image and its location, and display the analysis result and the original image on the computer On the display, the highest temperature is compared with ...
