A method for dismantling an automotive cascade battery module

Abstract

The invention discloses a method for disassembling an automobile ladder battery module, which includes the following steps: Step S1, disassemble the entire automobile battery module into a plurality of sub-modules; Step S2, remove the aluminum on the sub-module The wire is cut off; step S3, soak a single sub-module in deionized water at a preset temperature; step S4, pull apart the upper and lower battery cover brackets evenly; step S5, dry the moisture on the surface of the battery core; step S6, for The battery core is coated with anti-rust oil; in step S7, put a surface pad on the battery core, cover it with a PVC outer film and heat shrink it. In the above disassembly method, the entire set of automobile battery modules is first disassembled into multiple sub-modules, and then the sub-modules are soaked in warm deionized water, and then pulled apart evenly with a tooling jig to avoid the battery holder being damaged. Forcibly pulling apart effectively prevents leakage and deformation of the positive electrode cap of the battery core, thereby avoiding damage to the battery core. At the same time, the invention also improves the disassembly efficiency, improves the quality of the battery core, and effectively reduces costs and losses.

Description

technical field [0001] The invention relates to a dismantling method for an automobile battery, in particular to a dismantling method for an automobile cascade battery module. Background technique [0002] With the rapid development of the electric vehicle industry, the aluminum wire welding process leads the trend of the 18650 battery pack industry. Since the 18650 battery is assembled in a PVC-free mode, the surface of the battery is directly a metal surface, and the fixing of the battery and the bracket The method is glued and fixed. At present, there is no relatively perfect method for dismantling the battery pack of this kind of aluminum wire welding and glued fixed mode in the industry. Poor quality, high loss and other defects. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a dismantling method for automotive echelon battery modules that avoids damage to the battery cells, has high dismantling efficiency...
