Key points of quality control of battery PACK production line

(I) Raw material quality control

Single cell screening: Strict performance testing and screening of purchased single cells, 

including parameters such as capacity, internal resistance, voltage, etc., 

to ensure that the quality of single cells meets the requirements.

Quality of other parts: Strict incoming inspection should be carried 

out on parts such as protection boards, connecting wires, and shells to ensure their reliable quality.

(II) Production process quality control

Welding process control: There are many welding points in the battery PACK, 

and the welding quality directly affects the performance and safety of the battery. 

Welding parameters such as welding current, voltage, time, etc. should be strictly

 controlled, and welding quality inspections such as appearance inspection and tensile testing should be carried out.

Assembly process control: Ensure that the assembly process of the battery PACK 

meets the process requirements, such as the placement of the battery, the fixing method, 

the connection of the connecting wire, etc. At the same time, quality inspections should 

be carried out during the assembly process to promptly discover and correct problems.

Test process control: Conduct comprehensive performance and safety tests on the 

battery PACK, including capacity testing, internal resistance testing, charge and discharge testing,

 short circuit testing, overcharge and overdischarge testing, etc. The testing process should be 

carried out strictly in accordance with the standard operating procedures to ensure the accuracy and reliability of the test results.

(III) Finished product quality control

Appearance inspection: Perform an appearance inspection on the finished battery PACK 

to ensure that there are no obvious scratches, deformations, stains and other problems.

Performance testing: Test the performance of the finished battery PACK again to ensure 

that it meets the design requirements and relevant standards.

Packaging and storage: Reasonably package the finished battery PACK to ensure 

that it is not damaged during transportation and storage. At the same time, 

it should be stored in accordance with the prescribed storage conditions to avoid degradation of the battery PACK performance.

battery pack production line quality optimization measures

(I) Introduce advanced production equipment and technology

Automated production equipment: Use automated welding, assembly,

 testing and other equipment to improve production efficiency and quality stability.

Advanced testing technology: Such as online testing, non-destructive testing 

and other technologies, which can timely detect quality problems in the production process and improve product quality.

(II) Optimize production process

Welding process optimization: Improve welding quality and reliability by optimizing welding 

parameters and using new welding materials.

Assembly process optimization: Improve assembly processes and methods

 to improve assembly efficiency and quality.

Test process optimization: Optimize test plans and test processes

 to improve test efficiency and accuracy.

(III) Strengthen personnel training and management

Technical training: Provide professional technical training to production personnel 

to improve their operating skills and quality awareness.

Quality management training: Provide quality management training to management

 personnel to improve their quality management level and ability.

Performance appraisal: Establish a scientific performance appraisal system

 to motivate employees to improve work quality and efficiency.

(IV) Establish a sound quality management system

Quality management system: Formulate a sound quality management system, 

including quality objectives, quality control processes, quality inspection standards, etc.

Quality traceability system: Establish a quality traceability system that can trace the production

 process of the product and promptly discover and solve quality problems.

Continuous improvement mechanism: Establish a continuous improvement mechanism, 

regularly review and evaluate the quality management system, and continuously improve and perfect the quality management system.

The quality control and optimization of the battery PACK production line is a systematic project,

 which requires starting from the quality control of raw materials, production process, and finished product quality, 

and taking effective quality control points and optimization measures. By introducing advanced production equipment 

and technology, optimizing production processes, strengthening personnel training and management, and establishing 

a sound quality management system, the quality and reliability of battery PACK can be improved, market demand can be met, 

and a strong guarantee can be provided for the development of the enterprise.
