The 18650 lithium-ion battery is one of the most common lithium-ion batteries on the market at present. What are the key points about the PACK process of the 18650 lithium-ion battery? Let's take a look.

The 18650 lithium battery pack process is mainly formulated according to the structure of the PACK battery. Most 18650 lithium battery pack processes have similar characteristics, which are multiple in parallel and multiple in series. The 18650 lithium battery pack process has distinctive characteristics, among which the biggest feature is 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, the 18650 lithium battery pack includes: 18650 cell, battery protection plate, connecting nickel sheet, lead-out nickel sheet, green paper auxiliary material, insulating paper, wire or plug wire, PVC outer packaging or shell Output (including connector), key switch, power indicator, and auxiliary materials such as EVA, highland barley paper, plastic bracket, etc., together form the PACK, and most types of 18650 battery PACK are applicable to this process.

Design process skills of 18650 lithium battery pack with multiple parallel and multiple strings

1. Take the principle of priority and easy operation, that is, easy operation by employees.

2. Take the principle of giving priority to operation safety, that is, employees are not easy to short circuit or have better preventive measures during operation.

3. Adopt the principle of equipment, that is, use auxiliary equipment to complete without manual work as much as possible, at least semi-automatic.

4. The packaging design should be reasonable, easy to take and put, and the product should not be taken out of the customer for half a day.

18650 lithium battery pack process quality characteristics

1. The lithium battery with good quality needs to be provided by qualified and stable suppliers with good performance. The single battery can be used after passing a series of safety tests and performance tests.

2. It is required that the internal resistance of the battery be low and consistent. Regardless of 14.8V lithium battery pack or other energy storage battery packs, the low internal resistance shall be guaranteed to ensure the capacity, platform and heat dissipation of large current discharge.

3. The battery structure adopts ventilation design, and the space between two adjacent batteries is not less than 2mm. This structure requires that the battery be fixed with plastic support.

4. PACK battery factory uses slotted nickel sheet for spot welding. The size of nickel sheet meets the requirements of high current discharge. The nickel sheet material ensures low internal resistance, the spot welding machine ensures stable operation, and the welding needle ensures quality. The operator can operate after being trained and qualified. After spot welding, check whether the welding spot is firm. In addition, vibration test shall be conducted for each batch of products to verify the anti-vibration performance.

5. Different batches of batteries are made into typical finished products and life tests are carried out. The actual cycle life is obtained from the cycle test of the finished battery when the experience of the lithium battery PACK design specification is summarized.

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 tested at different times under high and low temperatures, and the actual discharge curve is obtained.

The above is the common PACK process points for 18650 lithium battery.
