Problems solved by technology

[0009] However, at present, there is no relatively mature set of recycling schemes at home and abroad. The current processing method is basically: waste power batteries are stored in a backlog in the warehouse after being scrapped. Long-term large backlog storage is likely to cause safety hazards, and there is no effective distribution and utilization of energy. good impact

Abstract

The invention provides a disassembling, recovering and cascade-utilizing method for a waste power battery pack. The method comprises the following steps: 1, reading data of the battery management system of the waste power battery pack, and judging the performance indexes of the whole battery pack according to the read data; 2, decomposing the waste power battery pack by using a pipeline automationrobot: disassembling the waste power battery pack step by step until single battery cells are dismantled; 3, performing capacity grading grouping on utilizable modules and single battery cells obtained after the disassembling and sorting of the waste power battery pack to perform recombining cascade utilization; and 4, performing material grade recovery on parts of cascade-unusable cells obtainedafter the disassembling and sorting of the waste power battery pack. The method has the characteristics of high recovery efficiency, energy saving, environmental protection and no secondary pollution.

Description

technical field [0001] The invention relates to the technical field of power battery packs, in particular to a method for dismantling, recycling and cascade utilization of waste power battery packs. Background technique [0002] The power battery pack is a battery that provides energy for the new energy vehicle power system. It consists of a battery pack (group) and a battery management system, including lithium-ion power batteries, metal hydride / nickel power batteries, etc., and does not contain lead-acid batteries. [0003] Waste power battery pack refers to: [0004] (1) The remaining capacity or charge and discharge performance after use cannot guarantee the normal driving of new energy vehicles or the power battery is no longer used after being disassembled for other reasons; [0005] (2) Scrapping the power battery on the new energy vehicle; [0006] (3) Traction batteries scrapped during the manufacturing process of battery manufacturers; [0007] (4) Other tractio...
