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.
