Pretreatment:

Information registration and testing: Register the information of the recycled battery packs 

and record the basic information such as the source, model, and service life of the battery packs. 

At the same time, use professional testing equipment to test the appearance, voltage, internal resistance 

and other parameters of the battery pack to determine the basic status of the battery pack 

and whether there are safety hazards, such as bulging, leakage, etc. For battery packs with safety risks, 

special marking and treatment are required.

Discharge treatment: There may be residual electricity in the battery pack. To ensure the safety of 

the disassembly process, discharge treatment is required. Usually, resistance discharge, 

constant current discharge and other methods are used to release the electricity in the battery

 pack to a safe level, and the voltage is generally required to drop to a lower safety value.

Shell disassembly:

Fix and position: Fix the battery pack on the disassembly workbench and use a positioning 

device to ensure that the battery pack does not move during the disassembly process. 

For some irregularly shaped battery packs, special clamps may be required to fix them 

so that subsequent disassembly operations can proceed smoothly.

Shell disassembly: According to the shell structure and connection method of the battery pack, 

select appropriate tools and methods for shell disassembly. For example, for a shell connected with screws, 

you can use tools such as an electric screwdriver to remove the screws; for a shell connected with a buckle, 

you need to use a professional pry bar or other tools to carefully pry open the buckle. During the disassembly process, 

be careful to avoid damage to the shell and internal battery components.

Module separation:

Internal structure observation and analysis: After opening the battery pack shell, observe the internal 

structure of the battery pack to understand the connection method and layout of the module. 

This step is very important for the subsequent module separation work, and requires careful 

observation and analysis in order to formulate a reasonable separation plan.

Module disassembly: According to the observed module connection method, 

use the corresponding tools and equipment to disassemble the module.

 If the modules are connected by welding, it may be necessary to use equipment such as laser 

cutting to separate them; if they are connected by bolts, use tools such as wrenches to remove 

the bolts. During the disassembly process, pay attention to protecting the integrity

 of the module and avoid damage to the battery cells inside the module.

Battery cell removal:

Remove the connection components: After the module is separated, each module

 contains multiple battery cells. First, it is necessary to remove the connection components 

between the battery cells, such as connecting pieces, wires, etc. These connecting parts 

may be connected by welding or plugging, and the appropriate method needs 

to be selected according to the specific situation to release them.

Battery cell removal: Use professional tools, such as suction cups, clamps, etc. 

to remove the battery cell from the module. During the removal process, be careful

to avoid damage such as squeezing and collision to the battery cell, and prevent the battery cell from short-circuiting.

Component classification and inspection:

Component classification: Classify and place the disassembled battery pack shell, 

module, battery cell and other components. For recyclable parts, such as battery cells, 

metal shells, etc., they should be stored separately; for waste that cannot be recycled, 

such as insulating materials, glue, etc., they should be classified and processed 

in accordance with environmental protection requirements.

Component inspection: Further inspection of the removed battery cells, including

inspection of parameters such as voltage, capacity, internal resistance, and appearance inspection. 

According to the test results, the battery cells are divided into different categories such as reusable, 

repairable and scrapped, so as to carry out corresponding treatment later.

Safe handling and environmental protection measures:

Safe handling: During the entire disassembly process, safety operating procedures 

must be strictly followed to prevent safety accidents such as battery short circuit, fire, 

explosion, etc. For sparks and static electricity generated during the disassembly process, 

corresponding protective measures must be taken, such as setting up anti-static 

equipment in the disassembly work area and equipping fire extinguishing equipment.

Environmental protection measures: During the disassembly of the battery pack, 

some waste and harmful substances will be generated, such as electrolyte, heavy metals, etc.

 Appropriate environmental protection measures must be taken to collect, treat and

 recycle these waste and harmful substances to prevent pollution to the environment.
