Problems solved by technology

In addition, soft-pack lithium batteries with the same tab distribution method also have different sizes, that is, the tab sizes are different, so the corresponding capacity structure is also different.
[0003] In order to adapt to different lug distribution methods and different lug sizes, it is necessary to change the type of the soft-pack lithium battery capacity-distribution movement mechanism, and the capacity-division test of the soft-pack lithium battery takes a long time and a large workload. During the process of type change, Low work efficiency, greatly increasing time cost and labor cost

Abstract

A capacity grading movement mechanism compatible with various types of polymer soft package lithium batteries comprises a mechanism bottom plate, probe position adjusting and clamping devices, a battery tray supporting device, a battery tray and an electrical component mounting block; the mechanism bottom plate is provided with an installation datum and is used for supporting and installing the components of the capacity grading movement mechanism; the probe position adjusting and clamping devices are symmetrically arranged on the left side and the right side of the mechanism bottom plate respectively and used for clamping polymer soft package lithium battery tabs; the battery tray supporting device is arranged on the mounting reference surface of the mechanism bottom plate, is positioned on the inner side of a tab position adjusting device and is used for bearing a soft package lithium battery tray; the battery tray is located over the battery tray supporting device and used for bearing soft package lithium batteries; and the electrical component mounting block is arranged on the mounting reference surface of the mechanism bottom plate. The mechanism has the beneficial effects that the mechanism has the characteristics of being simple in structure, easy to assemble, wide in applicability and the like; on one hand, the mechanism can adapt to soft package lithium batteries with different tab distribution modes, on the other hand, the mechanism is also convenient to adapt to soft package lithium batteries with different tab sizes, and has great applicability.

Description

technical field [0001] The invention relates to a capacity dividing movement mechanism compatible with various types of polymer soft pack lithium batteries, belonging to the technical field of soft pack lithium battery capacity dividing test equipment. Background technique [0002] Soft-pack lithium battery is a kind of lithium battery. The key materials used in it: positive electrode material, negative electrode material and separator, are not much different from traditional steel shell and aluminum shell lithium battery. The biggest difference lies in the flexible packaging material (aluminum-plastic composite film). The soft-pack lithium battery is only a layer of polymer casing on the liquid lithium-ion battery, and is structurally packaged with aluminum-plastic film. In the testing process of soft-pack lithium batteries, the capacity division test is to perform several full-load charge-discharge cycles on the activated battery to test the internal resistance and charge-...
