Problems solved by technology

[0003] In the existing technology, there is a risk of misjudgment in the voltage detection method. The existing method is to first detect the voltage once, then put it on hold, and then detect the voltage again after the end of the hold. , this screening method has low efficiency, large errors, and high probability of misjudgment, which is not conducive to the development of enterprises.

Description

technical field [0001] The invention belongs to the technical field of batteries, and in particular relates to a system and method for screening poor voltage drop of soft-packaged batteries. Background technique [0002] After the battery is formed, it is necessary to screen the batteries after formation, that is, to distinguish good batteries from defective batteries. [0003] In the existing technology, there is a risk of misjudgment in the voltage detection method. The existing method is to first detect the voltage once, then put it on hold, and then detect the voltage again after the end of the hold. , This screening method has low efficiency, large errors, and high probability of misjudgment, which is not conducive to the development of enterprises. [0004] In summary, there are defects in related technologies, which need to be improved urgently. Contents of the invention [0005] One of the purposes of the present invention is to provide a system for screening the...
