Features:
The general 18650 lithium battery pack includes: 18650 cell, battery protection board, connecting nickel strip, insulating paper, wire; PVC outer package or shell, output (including connector), key switch, power indicator, EVA, highland barley paper, plastic bracket and other auxiliary materials.
We provide a full series of Energy Storage Battery Assembly for different customers.
18650 Lithium Battery Pack Process Quality Features:
1. The use of qualified lithium batteries requires qualified and stable suppliers to provide single batteries with good performance. After a series of safety tests and performance tests, the single batteries can be used after they are qualified.
2. No matter 14.8V lithium battery pack or other energy storage battery pack, it should ensure low internal resistance, high current discharge capacity, platform and heat dissipation.
3. The structure of the battery adopts ventilation design, and the space between the two adjacent batteries is not less than 2mm. This structure requires the use of plastic bracket to fix the battery.
4. Pack battery factory uses slotted nickel strip in spot welding. The size of nickel strip meets the requirements of high current discharge. The material of nickel strip ensures low internal resistance. The spot welding machine ensures stable operation. The welding needle ensures quality. The operator can work after training and passing the examination. After spot welding, check whether the welding spot is firm. In addition, vibration tests were carried out 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. When the experience of lithium battery pack design specification is summarized, the battery finished products are tested to get 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 different rate discharge tests are carried out at high and low temperature to obtain the actual discharge curve.
Process Characteristics :
1.Adopt qualified lithium battery
2. Low internal resistance and good consistency

Important process:
First of all, the cells should be separated and paired before assembly, in order to ensure that there are no defective products.
The lithium battery sorter can be set to multiple gears through the upper and lower limits of internal resistance. The resistance is adjustable, and the adjustment mode is diversified and fast. It is equipped with imported voltage internal resistance tester, integrated PC, high-end drive, all electric motor configuration; Process detection signal comprehensive and bid farewell to a single industrial machine.
Our company manufactures various types of Li ion battery equipment. We welcome your contacts from any place of world.
For lithium battery spot welder, the thickness and material of welding workpiece have great influence on welding parameters. The welding electrode head of different materials and structures should be selected according to the thickness, sheet and material of the battery.
If the distance between the welding electrode tips is too large, the welding power will increase, and the required energy will increase accordingly. Generally, the distance between the two electrode tips is adjusted to 3mm, and the clamp of lithium battery needs to be paved with nickel sheet.
