18650 battery 3.7v 6000mah PACK process flow, battery PACK industry analysis

　　18650 battery 3.7v 6000mah PACK process flow, battery PACK industry analysis. Battery PACK: PACK means packaging, packaging, and assembly. The process is divided into three parts: processing, assembly, and packaging. The process of assembling 18650 battery 3.7v 6000mah cells into groups is called PACK, which can be a single battery or a series-parallel battery module. No matter what type of power battery cells, they must be packaged and inspected before they can be used in new energy vehicles.

　　18650 battery 3.7v 6000mah PACK process flow

　　The production process of 18650 battery 3.7v 6000mah PACK is relatively complex. PACK is the key to the production, design and application of power battery systems. It is the core link connecting the upstream battery production and downstream vehicle applications. Usually the design requirements are proposed by the battery factory or the automobile factory, usually by Completed by battery factory, automobile factory or third-party PACK factory.

　　The PACK of lithium batteries is realized in two ways. One is through laser welding or ultrasonic welding or pulse welding. This is a commonly used welding method. The advantage is that it has better reliability but is not easy to replace. The second is contact through elastic metal sheets. The advantage is that no welding is required and the battery is easy to replace. The disadvantage is that it may lead to poor contact.

　　What processes does the 18650 battery 3.7v 6000mah PACK production line contain?

　　1. Sorting and grouping process

　　2. Automatic welding process

　　3. Semi-finished product assembly process

　　4. Aging test process

　　5. PACK detection process

　　6. PACK packaging technology

　　Battery PACK industry analysis

　　As we all know, the battery PACK is the core energy source of new energy vehicles, providing driving power for the entire vehicle. It mainly forms the main body of the battery PACK through the shell envelope. The battery PACK mainly consists of battery cells, modules, electrical systems, thermal management systems, casings and BMS.

　　China's battery PACK production capacity is gradually expanding, and my country's power battery production scale is growing year by year. Especially in 2015, the industry growth rate was as high as 229.5%, and the capacity also exceeded 30 billion yuan, reaching 34.69 billion yuan. It is expected that by 2019 In 2019, the power battery PACK industry will form a market worth hundreds of billions.

　　It is understood that there are currently three types of market participants in my country's power battery PACK industry: battery cell manufacturers, vehicle companies and professional battery PACK companies. Their current market shares are 60%, 20% and 20% respectively. Relevant people in the industry believe that if the same standard module is used to build a battery PACK, it will not only be able to quickly provide suitable 18650 battery 3.7v 6000mah packs for different models, but also structurally optimize battery heat dissipation, improve the working efficiency of the battery PACK, reduce costs, and reduce R & D expense. In addition, companies that put into production according to unified production standards can also ensure the consistency, safety and reliability of battery packs to the greatest extent, making the production process more efficient.

　　Compared with the domestic new energy vehicle market, foreign competition is also becoming increasingly fierce. Car companies are trying to improve the cruising range of their vehicles, so they have entered the battery PACK field. As the power battery industry matures, battery PACK modular technology will become increasingly mature.

　　The development of battery PACK technology involves multi-disciplinary and multi-field knowledge and requires interdisciplinary technology integration. All in all, if car companies want to eventually produce PACK products on a large scale that fully meet the requirements of new energy vehicles in terms of life, stability, reliability, and safety, they still need a lot of engineering practice and test verification, as well as continuous product optimization and upgrading. process.

　　Summary: In the future, the trend of promotion and application of new energy vehicles will be further developed, and power batteries, as an important component of new energy vehicles, will also usher in a period of golden development opportunities. Among them, the power 18650 battery 3.7v 6000mah PACK industry will also get more development opportunities under the good situation of power batteries. The battery PACK industry will also usher in faster growth driven by new technologies and new models.
