Lithium battery PACK is a complex and delicate process. From the selection of lithium battery cells to the final lithium battery factory, each link is strictly controlled by PACK manufacturers, and the fineness of the process is crucial to quality assurance. Below I take you to explore the key process of lithium battery PACK technology, to understand how lithium battery PACK factory to ensure the high quality and reliability of the product.
Lithium cell sorting group
Li-ion battery PACK manufacturers will carefully select lithium cells (also known as A-grade cells) and accessories with excellent performance and stable quality to ensure that the initial performance of the PACK batteries is optimal. The above lithium cells are then sorted and grouped, which is a key part of the PACK process. Cyclone Electronics will conduct strict performance testing and screening of all the cells, and select the cells with the most similar performance for grouping to ensure the overall performance of the lithium battery is stable and reliable. Cyclone Electronics is also equipped with high-precision testing equipment, and over the past 30 years, it has been continuously exploring ways to improve the assembly method and process quality, so as to realize the energy density and extend the service life of lithium batteries through the improvement of the process.
Assembly and welding
A high level of welding process can ensure the structural firmness of the battery PACK. Spinli Electronics adopts advanced spot welding technology and equipment, and senior operators with more than ten years of experience, to perform precise and firm welding of series-parallel combinations of lithium cells, and connections between battery packs and PCM/BMS, to ensure the stability and reliability of the battery's internal structure. The welding process is carried out with European process standards for temperature control and welding quality checking.
Rigorous implementation of multi-channel testing
After welding, Spinning Electronics will carry out semi-finished charging and discharging, internal resistance, capacity, temperature rise, safety features and other tests, for special customized or special semi-finished batteries will be temperature, pinprick test, drop test, smoke test and other sampling tests; for the finished lithium batteries Spinning Electronics will also carry out aging tests, so that lithium batteries are more stable after the initial charging of the internal, and to enhance the life of the battery. Finally, we will also carry out comprehensive testing of finished lithium batteries to ensure that the factory's lithium batteries have good performance in the hands of users, some batteries will also be waterproof, collision and other sampling tests.
Advanced management system, production environment and equipment
Spinning force electronic strictly abide by ISO quality management system, more use of automated production lines and advanced process equipment, all employees are required to standardized dress, special positions will be equipped with tools such as static electricity hand ring, to ensure the quality and reliability of the battery, to provide customers with trustworthy lithium battery products.
With the advancement of technology and market requirements, Spinning Power's lithium battery PACK processes and procedures will be continuously optimized and innovated to improve production quality while reducing costs and increasing efficiency, to provide customers with a steady stream of competitive products and help customers to win the market.
