18650 lithium-ion battery PACK process welding should pay attention to? The 18650 lithium-ion battery is now one of the most common lithium-ion batteries on the market. The cylindrical batteries commonly used in the battery pack, that is, the 18650, 21700, 32650 specifications of the unit. The 18650 lithium-ion battery PACK process is important to formulate according to the PACK battery structure, and most of the 18650 lithium electric PACK process features are similar.

18650 lithium-ion battery PACK process welding should pay attention to? 1,18,650 Lithium-ion battery should pay attention to the current of spot welding. 2,18650 Lithium-ion battery should pay attention to the diameter of the solder needle when welding. 3,18650 Lithium-ion battery should pay attention to the welding pin pitch when welding.

4,18650 Lithium-ion battery PACK process welding should pay attention to the number of solder joints. 5, can not be fried when spot welding, can not be shorted, can not be soldered. Multiple stringed 18650 lithium-ion battery PACK design process skills 1, the principle of priority, that is, employee easy operation.

2. Take the principle of priority safety, that is, the employee is not easy to short or have better preventive measures. 3.

Take the equipment principle, that is, without manual, at least semi-automated as much as possible with the auxiliary equipment. 4, packaging design is reasonable, easy to put, don't get it, you can't get it in the customer. In 18650, there are a variety of non-consistent reasons for the Pack of lithium ion battery.

The material of the constituent battery itself is incomplete, and the process of manufacturing the battery cannot be controlled to each battery in any detail. This will result in inconsistent capacity, inconsistent with the end voltage, inconsistency in internal resistance, and the life is inconsistent. In addition to electrical performance, the appearance of 18650 lithium ion batteries should be tested.

For example, the scratches, damage, stains, pits, bumps such as the surface of the battery can affect the assembly of the battery module and the latter security characteristics. Summary: 18650 Lithium Ion Battery Pack is designed to be screening, different customers are completely different from the battery cells before 18650 lithium ion battery PACK, due to the high level of production of 18650 lithium ion power lithium battery, better stability, High replaceability, can effectively reduce production costs, save labor, so that 18650 batteries have unique advantages in the modularity of system development and standardization.
