Lithium-ion Battery Pack Manufacturing Process & Design
Step One: Cell Sorting. The cell sorting stage is a critical step in ensuring the consistent performance of lithium-ion batteries. The lithium-ion battery manufacturer should have a strict gap standard of less 5mv voltage gap, less 15mΩ internal resistance, and less 5mAh capacity gap. To ensure the li-ion battery with a long-lasting cycle and ...
To create a 12V battery pack, you will need to connect four 18650 cells in series. To do this, connect the positive terminal of one cell to the negative terminal of the next cell using a pure nickel strip. Repeat this process until you …
Layout The Cells for Spot Welding. Now that we know our battery pack will be in 3S2P configuration, we can put the cells together. We have 2 cells each in the parallel groups ( 5000 mAh x 2 = 10000 mAh) and we have 3 of those groups in series. To begin, place the first parallel group of 2 cells positive side up.
To make the battery pack, you will have to electrically connect the 18650 cells together. This is most commonly done using a spot welder and nickel strip. Avoid nickel-plated strips, and instead, opt for pure nickel strips. They cost a little more, but pure nickel strip has far lower electrical resistance.
So in this tutorial, I will show you how you can make a 18650 Li-ion Battery Pack with a BMS circuit and all the things you need to know before you built one! Step 1: Watch the Video! If you don''t want to read all the stuff watch …
