Research progress of automatic dismantling technology of new energy vehicle traction battery

Abstract

As a key pre-process link of comprehensive utilization of traction battery - traction battery dismantling, which is related to the efficiency and value of comprehensive utilization. At present, the industry has carried out automatic, intelligent and refined disassembly process and research and construction of production line, but with the application of complex battery pack structure design such as gluing, the disassembly difficulty is also significantly increased. And in the face of how to control the robot screw removal machine automatically identify the location of the battery pack cover screws, how to ensure automatic screw removal yield, how to alarm the screw removal abnormalities, how to automatically identify and locate the battery module long screws and nuts, how to successfully remove the screws and nuts at different angles, how to successfully remove the copper row on the module when the battery pack positioning accuracy deviations and other key technical problems, the industry has also explored different technical routes. Based on the current situation of the comprehensive utilization industry of new energy vehicle traction battery, this paper compares the traction battery technology profile and its key technology development in the disassembly process, and proposes development suggestions to deal with the disassembly technology bottleneck by analyzing the development of enterprise technology and development of production line equipment, so as to point out the direction for the industry to improve the traction battery disassembly technology level and help the new energy vehicle and traction battery recycling industry to develop healthily and sustainably.
