18650 lithium-ion battery is one of the most common lithium-ion batteries currently on the market. So what are the key points about the PACK process of 18650 lithium-ion battery? Let’s take a look below.
The 18650 lithium battery pack process is mainly formulated based on the PACK battery structure. Most of the 18650 lithium battery pack process features are similar, with multiple parallels and multiple series. The 18650 lithium battery PACK process has distinctive features. The biggest feature is the flexible combination. Most continuous orders can be completed semi-automatically. It is conceivable that the 18650 lithium battery pack process is becoming more and more streamlined. Generally, 18650 lithium batteries PACK battery pack includes: 18650 battery cells, battery protection plate, connecting nickel sheet, lead nickel sheet, green paper accessories, insulating paper, wires or plug wires, PVC outer packaging or shell, output (including connectors), key switch, The battery indicator, as well as auxiliary materials such as EVA, highland barley paper, and plastic brackets, together form the PACK, and most types of 18650 battery PACK are suitable for this process.
Multi-parallel multi-string 18650 lithium battery pack design technology skills
1. Adopt the principle of giving priority to easy operation, that is, easy operation by employees.
Low temperature lithium iron phosphate battery 3.2V 20A -20℃ charging, -40℃ 3C discharge capacity ≥70%
Charging temperature: -20~45℃ -Discharge temperature: -40~+55℃ -40℃ Support maximum discharge rate: 3C -40℃ 3C discharge capacity retention rate ≥70%

2. Adopt the principle of giving priority to operational safety, that is, employees are not prone to short circuits or have better preventive measures when operating.
3. Adopt the equipment principle, that is, use auxiliary equipment to complete the work without manual labor as much as possible, at least semi-automatically.
4. The packaging design must be reasonable, easy to take and put away, and the product should not be left out for a long time after the product is delivered to the customer.
18650 lithium battery pack process quality characteristics
1. To use lithium batteries with acceptable quality, qualified and stable suppliers are required to provide single cells with good performance. The single cells must undergo a series of safety tests and performance tests and be used after passing them.
Low temperature and high energy density 18650 3350mAh-40℃ 0.5C discharge capacity ≥60%
Charging temperature: 0~45℃ Discharge temperature: -40~+55℃ Specific energy: 240Wh/kg -40℃ Discharge capacity retention rate: 0.5C Discharge capacity ≥ 60%

2. The battery is required to have low internal resistance and good consistency. Whether it is a 14.8V lithium battery pack or other energy storage battery pack, low internal resistance must be ensured to ensure the capacity, platform, and heat dissipation of large current discharge.
3. The battery structure adopts a ventilation design, and a spacing of no less than 2mm should be maintained between two adjacent batteries. This structure requires the battery to be fixed with a plastic bracket.
4. The PACK battery factory uses slotted nickel sheets for spot welding. The size of the nickel sheets meets the requirements for large current discharge. The nickel sheet material ensures low internal resistance. The spot welding machine ensures stable operation. The welding needles ensure quality. The operator has been trained and assessed and qualified. After starting the operation, check whether the solder joints are firm after spot welding. In addition, vibration tests are conducted on each batch of products to verify the anti-vibration performance.
5. Different batches of batteries are made into typical finished products and subjected to life tests. When the lithium battery PACK design specification experience is summarized, the finished battery products are subjected to cycle tests to obtain the actual cycle life.
6. Verify the high and low temperature performance of the battery. The cells of different PACK lithium battery manufacturers are made into finished products and discharged at different rates under high and low temperatures to obtain actual discharge curves. OFweek Lithium Grid
