The rapid development of electric vehicle and energy storage equipment market, power lithium battery Pack as one of the core components of electric vehicle and energy storage system, its production process is particularly important. This article will introduce the production process of power lithium battery Pack, including cell manufacturing, cell testing, cell assembly, Pack testing and Pack finished product manufacturing, to help readers understand the production process of power lithium battery Pack more comprehensively.

1. Manufactured in cell

the production process of power lithium battery Pack starts from cell. Cell is the core component of lithium battery, and its manufacturing process includes the preparation of positive electrode material and negative electrode material, the preparation of electrolyte, the manufacture of cell shell, etc. In the manufacturing process of cell, it is necessary to ensure the purity and quality of materials, as well as the stability and consistency of production processes to ensure the performance and safety of cell.

2. Cell test

after manufacturing in cell, cell tests are required to verify the performance and quality of cell. Cell tests include capacity test, internal resistance test, cycle life test and other links. The performance and stability of the cell are evaluated through test results, and qualified cell are selected for subsequent production processes.

3. Cell assembly

after the qualified cell is tested, cell assembly will be carried out. Cell assembly is to assemble components such as positive electrode, negative electrode, diaphragm and electrolyte together to form a complete cell structure. During the cell assembly process, the assembly process and process parameters need to be strictly controlled to ensure cell performance and safety.

<strong>4. Pack test

Pack Test will be performed on the assembled cell. Pack test is to test the performance and evaluate the safety of the entire battery Pack. The test content includes the overall capacity test, cycle life test, thermal runaway test and other links to ensure that the Pack's performance and safety meet the requirements.

5. Pack finished product manufacturing

battery packs that pass the Pack test will be manufactured. Finished product manufacturing includes the manufacture of Pack shell, installation of BMS (battery management system), installation of connectors and other links. Finally, a complete power lithium battery Pack product is formed, which can be applied to electric vehicles, energy storage systems and other fields.

6. Quality control and tracing

in the whole production process of power lithium battery Pack, quality control and tracing are very important links. Through strict quality control and traceability system, the quality and reliability of products can be ensured, and the production efficiency and product quality can be improved.

7. Environmental Protection and Safety

in the production process of power lithium battery Pack, environmental protection and safety are also crucial considerations. In the production process, it is necessary to abide by relevant environmental protection regulations and safety standards, and take appropriate measures to ensure the safety of employees and production equipment and reduce the impact on the environment.

8. Innovation and development

with the continuous progress of science and technology and the continuous change of market demand, the production technology of power lithium battery Pack is also constantly innovating and developing. NoIntroduce new materials, processes and technologies to improve production efficiency and product performance, and promote the sustainable development of power lithium battery Pack industry.
