Problems solved by technology
[0002] In order to ensure the performance of the battery, especially the discharge rate and cycle times of the battery, it is generally necessary to measure the internal resistance of the battery during the production process of the battery. The existing fixture for measuring the internal resistance is a clip, and the operator operates it manually. The operation is inconvenient, the detection efficiency is low, and the accuracy and precision of the measured battery internal resistance are not high

The invention relates to a clamp, in particular to an internal resistance measuring clamp of a battery. The internal resistance measuring clamp comprises a bearing plate, wherein a baffle is arranged at one end of the bearing plate, a testing terminal is arranged on the baffle and connected with two leads connected with a testing machine, an electrical core positioning testing block is arranged at an edge of the bearing plate perpendicular to the baffle, and a contact connected with an electrical core and a lead for connecting the contact with the testing machine are arranged on the testing block. When the internal resistance measuring clamp is used, users can place the electrical core on the bearing plate and connect an electrical core contact with the contact on the clamp in alignment mode, so that internal resistance of the battery can be measured, and the problem of alignment accuracy caused by the fact that the clamp is held artificially is solved. Further, the internal resistance clamp is easy and convenient to operate, improves working efficiency and is high in accuracy and precision.
Description
technical field [0001] The invention relates to a fixture, in particular to a fixture for measuring battery internal resistance during battery processing. Background technique [0002] In order to ensure the performance of the battery, especially the discharge rate and cycle times of the battery, it is generally necessary to measure the internal resistance of the battery during the production process of the battery. The existing fixture for measuring the internal resistance is a clip, and the operator operates it manually. The operation is inconvenient, the detection efficiency is low, and the accuracy and precision of the measured battery internal resistance are not high. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned defects, and provide a battery internal resistance measuring jig with convenient operation, high efficiency, high accuracy and precision. [0004] To achieve the above object, the present invention ado...
