Lithium Ion Battery Pack Assembly Line
There are many production processes for lithium batteries, including front-end and back-end, and the input cost is very high. Due to the increasing business volume, many friends have opened Lithium Ion Battery Pack Assembly Lines by themselves. However, there are still some friends who do not quite understand the equipment needed for lithium battery assembly and production pack lines. I will continue to share relevant knowledge here for the convenience of friends who need to know.
Brief Introduction of New Energy Lithium Battery Assembly Pack Line
Some friends will ask how much a set of lithium battery pack assembly line equipment costs. In fact, there is a lot of equipment, you need to know your output to determine, because some equipment is automatic, and some are manual. The prices vary a lot, and there is no need to go to the automatic line if the output is not a lot, so you must first explain your specific needs, and then give a plan and quotation.
Lithium battery pack line process introduction
1. Cell capacity
Test a single battery cell: whether the capacity, rate, cycle times, etc. meet the requirements.
2. Sorting and pairing of single cells
Sorting is carried out according to the set voltage and internal resistance value to ensure its consistency.
3. The positive electrode is pasted with barley paper
Prevent short circuit caused by high temperature of battery.
4. Welding nickel sheet for battery pack
5. Welding protection plate
6. Comprehensive test of semi-finished products
Test the theoretical design parameters after connecting the battery pack and protection board
7. Aging test
Charge and discharge cycle test
8. Waterproof, insulating bracket, and labeling into the shell.
Equipment required for lithium battery assembly production pack line
1. Sub-container
The capacity, rate, cycle times and other data of the battery can be measured directly with the sub-container.
2. Battery automatic sorting machine
The 6-speed sorting machine and the 10-speed sorting machine are used more often, and other channels can be customized according to customer requirements.
3. The positive sticker can be pasted manually, or it can be pasted automatically by an automatic sticking barley paper machine
4. Manual spot welding machines and automatic spot welding machines are available
Among them, the manual spot welding machine can be divided into AC spot welding machine, DC spot welding machine and transistor spot welding machine. Automatic spot welding machines include single-sided automatic spot welding machines, series-parallel automatic spot welding machines, double-sided automatic spot welding machines and sticker test series-parallel spot welding machines and so on.
5. The same is true for the welding protection plate, which can be semi-automatic or automatic spot welding machine
6. Finished product comprehensive tester
50V60A, 100V120A, 100V200A, etc.
7. Aging cabinet
30V10A charge 20A, 70V5A charge 20A, 70V10A charge 20A, 84V10A charge 14A, 100V10A charge 14A, 100V10A charge 20A, etc.
The above is the new energy lithium battery assembly production pack line process and the required equipment, I hope it can help you understand the reference. The writing is relatively simple, which is convenient for basic understanding. If you need in-depth and detailed understanding, welcome to communicate!
