Description

technical field

[0001] The invention relates to the technical field of battery testing. Background technique

[0002] When the pouch battery clamp in the prior art clamps the tabs of the battery, it is easy to cause the tabs to break. At the same time, when testing high-current pouch batteries, the contact area between the tabs of the battery to be tested and the current clamp is small, and the impedance is large, which can easily lead to overheating of the clamp and the battery, causing certain dangers. Contents of the invention

[0003] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a high-current pouch battery test bed of needles, which can avoid damage to the tabs during the testing process, and can increase the size of the tabs of the battery to be tested. The contact area between the clamp and the current clamp reduces the impedance between the battery tab and the current clamp to avoid excessive heating of...
