Description

Technical Field

[0001] The utility model relates to the technical field of battery detection, and more specifically, to a battery internal resistance tester. Background Art

[0002] The battery internal resistance tester is a digital storage multifunctional portable test instrument that can quickly and accurately measure the battery operating status parameters. The current battery internal resistance tester consists of a tester, crocodile clips, a data export line and a USB flash drive. When testing, you need to connect the tester and the crocodile clips to the instrument, and then connect the crocodile clips to the battery under test, and then operate the tester to detect and test.

[0003] When operating the tester, you need to use your fingers to press the options on the screen according to the steps. Some people choose to use a stylus to operate, but the stylus is not set together with the tester, and it is easy to lose the stylus. When you need to export data, you need to find a data export cable and a USB flash drive to export the data to the USB flash drive. It is not convenient to use, and there is a risk of dropping the tester when taking it. Therefore, in view of the above problems, a battery internal resistance tester is proposed.
