Abstract

The invention discloses an open-circuit voltage measuring and determining device of a flexible-packaging lithium ion battery. The device comprises a rack, a transplanting assembly, and a needle plate assembly, a lead screw moving assembly, an eccentric assembly, a holding mechanism, a battery OCV measurement instrument, and a control mechanism. The transplanting assembly arranged on the rack is connected with a preposed logistics line and is used for conveying a battery tray plate; the lead screw moving assembly is used for enabling the needle plate assembly to decline to an electrode tab position, the eccentric assembly is used for deviating the needle plate assembly according to different battery types; the holding mechanism is used for clamping and localizing the battery tray plate. The needle plate assembly is electrically connected with the battery OCV measurement instrument by a conductive beam. The control mechanism arranged in a PC machine outside the rack is used for controlling the transplanting assembly, the lead screw moving assembly, the needle plate assembly, the eccentric assembly, the holding mechanism, and the battery OCV measurement instrument to move. According to the invention, on the basis of butt joint of a scanner, a computer, and a logistics system, full-automatic testing is realized rapidly and effectively.

Description

technical field [0001] The invention relates to a device for measuring the open circuit voltage of a soft-pack lithium ion battery, belonging to the technical field of lithium ion battery manufacturing equipment. Background technique [0002] With the improvement of scientific and technological level and the popularization of new energy technology, the utilization rate of soft-pack lithium-ion batteries is getting higher and higher. In order to improve the service life of lithium batteries, it is necessary to periodically conduct strict charging and discharging, aging, voltage and Internal resistance test. [0003] At present, most of the existing lithium battery OCV measurement methods are mainly based on manual measurement. First, the battery is taken out of the tray and fixed on a special container, and then the OCV measuring instrument is used to measure and record. This kind of measurement method is not only cumbersome, but also easy to cause data disorder, battery sho...
