Abstract

The invention provides a battery tab clamp. The battery tab clamp comprises two clamping plates with conductive surfaces, two rollers and a fixed structural part, wherein one ends of the two clampingplates are installed in the fixed structural part, the conductive surfaces of the two clamping plates are parallel, and a crack is formed between the two conductive surfaces; and the two rollers are respectively arranged at the other ends of the two clamping plates. According to the battery tab clamp, surface-to-surface contact between the battery tab and the clamp is realized, the contact resistance is effectively reduced, the heat generation under a high-magnification test condition is reduced, and the errors of high-magnification current measurement and temperature measurement are reduced.

Description

technical field [0001] The present application relates to the field of lithium-ion battery testing, in particular to a tab fixture for lithium-ion batteries. Background technique [0002] General common wireless handheld tools, remote control aircraft, automobiles and portable electrical appliances and other products with high power requirements have long used nickel-cadmium batteries or lead-acid batteries. Good, environmentally friendly lithium-ion batteries replaced. [0003] Lithium-ion batteries not only have high energy density, but also high power performance makes them gradually occupy the power market of high-power products. The start-stop power supply requires a battery rate of about 40C, and the instantaneous rate of ordinary pure electric vehicles also needs to reach about 3C when starting. In order to test whether the rate performance of the battery meets the requirements of use, it is necessary to test the rate performance of the finished battery cell, usuall...
