Abstract

The invention provides a laser remanufacturing method of a power lithium battery for heavy-duty equipment. The laser remanufacturing method of the lithium battery for heavy-duty equipment includes the following steps: S1. Place the damaged lithium battery for heavy-duty equipment in a battery dismantling device, so that the lithium battery casing is separated from the lithium battery body. The invention provides a laser remanufacturing method for power lithium batteries of heavy-duty equipment, which mainly uses laser surface alloying technology and laser cladding technology to respectively repair the bent pole plate and cracked pole plate, and repair the damaged pole plate, Complete the maintenance of the entire lithium battery, try to avoid direct replacement of new plates, make full use of the limited plates, and avoid waste of resources. For manufacturers who are used for many lifting assemblies at the same time, it greatly saves the maintenance of lithium batteries After repairing, a new surface alloy layer based on the original base material is formed, which greatly increases the overall strength of the plate.

Description

technical field [0001] The invention relates to the field of lithium batteries, in particular to a laser remanufacturing method of a power lithium battery for heavy-duty equipment. Background technique [0002] Heavy-duty equipment, also known as cranes, refers to multi-action hoisting machinery that vertically lifts and horizontally transports heavy objects within a certain range. The corresponding mechanism of the action works alternately, and the development and use of cranes in the market are more and more extensive. [0003] For small heavy-duty equipment, the power source is mainly provided by its internal power lithium battery. However, when the workload to be transported is large, the lithium battery needs to work under high load for a long time, so that the storage battery continues to discharge rapidly, and then It is easy to cause the inner plate of the lithium battery to be bent, even cracked, and the active material on the conductive coating to fall off, which ...
