When many people understand the lithium battery PACK production line, they will pay attention to it at first sight: Automatic PACK line, Cell assembly equipment.These “big machines” are really important, but those who have really done battery factories know that whether a production line can run stably for a long time depends on those “backup Equipment“.This article will collate a lot of auxiliary equipment that is often used in the production of lithium battery PACK. From Sorting Machine, Spot Welding Machine, CCD Polarity Detection and Aging Cabinet, it basically covers several core links in PACK production.
Why is PACK production increasingly dependent on Backup Equipment?
The current lithium battery industry is actually not the same as in previous years.A lot of small PACK factories:manual testing, manual spot welding, manual sorting, They can also produce.But now: Energy storage capacity is increasing Electric vehicles are increasingly demanding, UAV batteries are becoming lighter and lighter, The industry’s requirements for consistency and security are already much higher.In particular: A problem with one battery may affect the entire PACK.So now many factories will pay more attention to:Aging Cabinet, CCD Polarity Detection, Protection Board BMS Tester and so on, All of these are part of Backup Equipment.
Xiaowei backup equipment list introduction
Spot Welding Machine
Spot welding is a key link in the production of lithium battery PACK, which is mainly used to reliably weld the battery cell with nickel sheet and other connecting materials to ensure stable current transmission and normal operation of the battery pack.
| Project | Message |
| Suit for | Cylindrical / Prismatic Battery Pack Line |
| Application | Battery tab welding / nickel strip welding |
| Degree of automation | Semi-automatic/automatic |
| Welding material | Nickel sheet, nickel-plated steel strip |
Although it doesn’t sound complicated, welding quality directly affects:PACK stability, service life, A lot of late heating, false welding problems, in fact, are related to welding.
Aging Cabinet
After the battery PACK is completed, it is not immediately shipped, but also needs to undergo aging testing. The aging cabinet will simulate different use environments, such as cyclic charge and discharge, high and low temperature and long-term operation, so that some potential problems can be exposed in advance, which can not only screen out unstable battery packs, but also make the overall performance more stable and safe.
| Project | Message |
| Test mode | Charge/discharge cycle verification |
| Number of channels | 8–256 |
| Application scenarios | PACK detection |
| Applicable types | All Lithium Battery Lines |
Sorting Machine
Battery sorting machine is mainly used to detect and classify parameters such as voltage, internal resistance and capacity of batteries. It is a very important process in the production of lithium battery PACK. By sorting, cells with similar performance can be grouped into the same group, thereby improving the consistency and stability of the battery pack.
| Project | Message |
| Sorting mode | Voltage / internal resistance sorting |
| Applicable types | Automatic cell grading & sorting |
| Number of channels | 5 – 20 channels |
| Process Stage | Cell Preparation |
CCD Polarity Detection
CCD polarity detector is mainly used to automatically detect whether the positive and negative direction of the battery is correct, and it is one of the very important detection equipment in the production of lithium battery PACK. It uses CCD vision system to quickly identify batteries, avoiding problems such as reverse polarity, missing installation or wrong position during battery assembly.
| Project | Message |
| Detection mode | CCD vision recognition |
| Detection content | Positive and negative direction, position, defect |
| Process Stage | PACK Assembly Detection |
| Application | Visual inspection & error prevention |
Protection Board BMS Tester
BMS (Battery Management System) is the core control unit of battery system, which is mainly responsible for real-time monitoring of key parameters such as voltage, current and temperature, and for battery charge and discharge protection, balance management, thermal management and fault alarm. It can guarantee the safe and stable operation of the battery pack and is called the “brain” of the entire battery system.
| Project | Message |
| Test object | BMS protection plate |
| Application stage | factory inspection |
| Test item | Voltage, current, protection function |
| Suit for | Lithium Battery PACK |
Compared to manual testing, BMS testers can:
- improve the detection efficiency
- Reduce false positives
- Auto-save test data
- Improve product consistency
In addition to these core devices, there are actually a lot of backup devices about batteries in the website.such as:
- PVC Heat Shrinking Machine
- EOL Tester
- Battery Cell Feeding Rack
- Pack Charge & Discharge Tester
These devices, while not necessarily “core hosts,” directly impact degree of automation, labor cost, production efficiency, product consistency.
Conclusion
With the increasing requirements for lithium batteries in energy storage, electric vehicles, drones and other industries, PACK production is gradually developing towards automation, intelligence and high consistency. More and more factories are paying attention to inspection, data management and production stability, which cannot be separated from the complete auxiliary equipment support.For lithium battery PACK production, a truly stable production line is not only “able to produce”, but more importantly, it can maintain stable product quality for a long time, reduce defective rate and improve overall production efficiency.As a professional turnkey service provider for lithium battery production, Xiaowei has more than 500 successful cases.
