The probe is irregular in shape, and the actual contact area between the probe and the battery is different each time it is pasted or when different people paste it, resulting in large measurement errors and poor reproducibility. In addition, the tape pasting method requires the use of a large amount of tape, which affects the environment in the long run.

[0032] Preferably, the battery 1 is provided with a wire protection sleeve, and the wire 7 is provided through the wire protection sleeve. The provision of the wire protection sleeve effectively prevents the surface of the wire 7 from being separated from the battery 1, and avoids the high temperature of the battery from damaging the wire 7.
[0033] Preferably, the wire protection sleeve includes a high temperature resistant heat insulating tube 11, which is a round tube structure, and the wire 7 passes through the inside of the high temperature resistant heat insulating tube 11 and is connected to the connection socket of the detection element. A plurality of connection seats 12 are provided on the high temperature resistant heat insulating tube 11.

[0034] Preferably, a wear-resistant layer is provided on the inner wall of the high temperature resistant heat insulating tube 11. The wear-resistant layer is provided to prevent the wire 7 from moving back and forth and rubbing, which affects the service life of the high temperature resistant heat insulating tube 11.
[0035] Preferably, the connection seat 12 is a high temperature resistant suction cup, and the high temperature resistant heat insulation cylinder 11 can be fixed directly by the suction effect of the suction cup.
[0036] When in use, the high temperature resistant heat insulation tube 11 is fixedly adsorbed on the surface of the battery 1, and the detection probe 4 is placed on the surface of the battery 1. The wire 7 passes through the inner wall of the high temperature resistant heat insulation tube 11 and is connected to the detection element 2. The adsorption plate 6 is pressed to fix the detection probe 4 on the battery 1. The detection data obtained by the sensor probe 5 will be transmitted to the detection element 2.
