Automatic disassembly line of retired battery of electric vehicle

Abstract

The invention relates to an automatic disassembly line of a retired battery of an electric vehicle. The automatic disassembly line is used for disassembling the retired battery of the electric vehiclein a gradient. By the automatic disassembly line, the retired battery of the electric vehicle is sequentially disassembled according to a sequence of a battery pack, a battery module and a minimum series and parallel unit. The disassembly line comprises a plurality of stations, and running is performed among stations by employing a roller and a speed chain body. Compared with the prior art, the automatic disassembly line has the advantages of automation, high compatibility, gradient optimization and disassembly, space saving and the like, and is flexible to adjust.

Description

technical field [0001] The invention relates to the field of electric vehicle decommissioned battery recycling, in particular to an automatic dismantling line for electric vehicle decommissioned batteries. Background technique [0002] As policy adjustments become clearer, market norms gradually put in place, and technological innovation continues to deepen, the new energy vehicle industry will still be in a stage of rapid development at present and in the next 3-5 years, and the number of new energy vehicles will increase rapidly, leading to a Rapid growth, it is speculated that retired EV batteries will reach 27GWh and 4.2GWh in 2020, and 84GWh and 17.5GWh in 2023, respectively. If such a large number of waste power batteries are not effectively recycled and properly disposed of, it will cause a great waste of resources, a huge pressure on the social environment, and then cause serious harm to human health. [0003] At present, the research on cascade utilization and recy...

Problems solved by technology

At present, in the demonstration projects or projects of battery cascade utilization, the dismantling of all processes of the battery, such as the disassembly of the battery system, PACK, battery pack, and module, is carried out manually. In fact, such an operation process is quite irregular and inconsistent. Requirements: First of all, for operators, since electric vehicle batteries are high-voltage systems (above several hundred volts) and are dangerous, inflammable and explosive items, manual disassembly of high-voltage electric shock safety, insulation leakage safety, and fire and explosion protection are all important. It is a great hidden danger; secondly, the manual dismantling process is relatively random, and the damage to the battery is unpredictable, and there is no unified storage or placement station for the classification and processing of various parts disassembled; third, The efficiency of manual dismantling is low. There are many types and models of electric vehicle batteries. Whether there is a drainage system, whether the ground is leak-proof, whether there are fire alarms, whether there are emergency passages, and whether the waste liquid and waste are collected and treated are all problems.

[0006] The detection and evaluation of retired batteries, according to the current general method, is to disassemble the battery pack into modules, disassemble the modules into monomers, and then test the monomers one by one. After the test, follow the assembly process of the new battery: a single battery Core—small module—large module—battery pack—PACK—battery system, the cascade utilization of batteries has gone through the process of disassembly, testing and assembly, and the latter two processes are more than the use of new batteries, which brings The problem is that the workload is huge, the work is tedious, consumes a lot of manpower, time and equipment cost, and the cascade utilization is completely uneconomical
