Problems solved by technology

[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 this kind of battery pack fixed by aluminum wire welding and glued in the industry. Defects such as poor quality and high loss

Embodiment Construction

[0014] The present invention will be described in more detail below in conjunction with the accompanying drawings and embodiments.

[0015] The invention discloses a dismantling method of an automobile cascade battery module, please refer to figure 1 , which includes the following steps:

[0016] Step S1, dismantling the entire set of vehicle battery modules into multiple sub-modules;

[0017] Step S2, breaking off the aluminum wires between adjacent sub-modules;

[0018] Step S3, immersing a single sub-module in deionized water at a preset temperature;

[0019] Step S4, pull the upper and lower battery cover brackets evenly;

[0020] Step S5, drying the moisture on the surface of the cell;

[0021] Step S6, coating the battery cell with anti-rust oil;

[0022] In step S7, a face pad is placed on the battery cell, a PVC outer film is covered, and heat shrinking is performed.

[0023] The battery for the above method is the aluminum wire welding process automotive cascade...

Abstract

The invention discloses a disassembly method of a car ladder battery module, which comprises the following steps: step S1, disassembling a whole set of car battery modules into a plurality of sub-modules; step S2, breaking the aluminum wires on the sub-modules; step S3, immersing each single sub-module in deionized water with a preset temperature; step S4, evenly pulling that upper and lower coverbrackets of the battery apart; step S5, drying the water on the surface of the battery cells; step S6, applying antirust oil on the battery cells; step S7, attaching a surface pad on the battery cells, arranging the PVC outer film and carrying out heat shrinkage. At first, a whole set of car battery modules is disassembled into a plurality of sub-modules which are immersed in warm deionized water; the upper and lower cover brackets are pulled apart through tools and jigs with even force instead of being pulled apart forcibly, so that the leakage and deformation at positive electrode cap of cells are effectively prevented and damage to cells is prevented. The invention also improve the disassembly efficiency, improves the quality of the battery cell, and effectively reduce the cost and theloss.

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...
