[0002] Lithium-ion batteries have the advantages of high specific energy, many cycle times, long storage time, etc., and are widely used in various fields. For example, they are used in electric bicycles, electric vehicles, mobile base stations, energy storage power stations and other fields. A battery pack is usually composed of multiple single cells in series and parallel. The capacity and life of the battery pack are not only related to each single cell, but also to the consistency between each cell. Therefore, the quality of the cell directly determines the quality of the battery.

[0003] During the production process of the cell, before the cell integration module is put on the line, to detect data such as the voltage and resistance of the cell, it is necessary to use the red and black test leads of a special detection device to touch the positive and negative terminal posts of the cell. Since the cell data needs to be recorded, before the detection device touches the terminal post, it is necessary to scan the QR code of the cell and then measure the cell data, so as to form corresponding traceability. In this process, the tester needs to hold the QR code scanner in one hand to complete the scanning and then hold the test lead to measure in the other hand. This process wastes working hours and is prone to errors. Therefore, there is an urgent need for a convenient detection device. Summary of the Utility Model
