Problems solved by technology
However, this type of battery cannot be detected by a short-circuit test after assembly, causing the battery with potential safety hazards to continue to flow into the next process, and it cannot even be found before shipment. It must be used for as long as half a month to find its own Large discharge phenomenon, this type of battery directly causes low efficiency of product use, and there are serious safety hazards at the same time, affecting product quality, finished product qualification rate and production efficiency

The invention relates to the technical field of a lithium ion battery and particularly relates to a short-circuit testing device and testing method for a lithium ion battery after assembling. The short-circuit testing device for the lithium ion battery after assembling comprises a short-circuit tester, a vacuum negative-pressure glove box, PE (Poly Ethylene) work gloves and a work tabletop for placing the lithium ion battery to be tested, wherein the vacuum negative-pressure glove box is arranged on the work tabletop; the vacuum negative-pressure glove box is provided with a vacuum pipeline; the PE work gloves are arranged in the vacuum negative-pressure glove box; the short-circuit tester is provided with a positive-negative meter probe and an alarm; and the positive-negative meter probe is arranged in the vacuum negative-pressure glove box. By using the short-circuit testing device and the testing method, micro-short-circuit batteries can be prevented from flowing into a posterior procedure and even being delivered to cause potential safety hazard, and the using efficiency of the products, the product quality, the pass percent of the finished products and the production efficiency are effectively enhanced.
Description
technical field [0001] The invention relates to the technical field of lithium-ion batteries, in particular to a short-circuit test device and a test method for assembled lithium-ion batteries. Background technique [0002] Lithium-ion batteries have the advantages of high voltage, large capacity, long cycle life, no memory effect, light weight, and wide working range. At present, the market has higher and higher requirements for the performance and internal structure of lithium-ion batteries, requiring battery life longer. [0003] The internal micro-short circuit of the lithium-ion battery will directly affect the instability of the battery voltage, and even cause serious safety hazards. Therefore, the assembled battery must be subjected to a short-circuit test before subsequent operations can be performed to prevent the short-circuited battery from flowing into the rear section. The existing short-circuit test is carried out in the normal pressure environment of the prod...
