Many battery packs use a combination of series and parallel connections to achieve the desired voltage and capacity. This configuration is often referred to as a series-parallel arrangement. Let's design a battery pack using 18650 cells (3.7V, 3000mAh each) with a 4S3P configuration (4 series, 3 parallel). 6. Practical Considerations
In the world of portable electronics and electric vehicles, battery packs play a crucial role. Two popular cell types used in these packs are 18650 and 21700 cells. The 18650 cell, measuring 18mm in diameter and 65mm in length, has been a staple in the industry for years.
This combination of cells is called a battery. Sometimes battery packs are used in both configurations together to get the desired voltage and high capacity. This configuration is found in the laptop battery, which has four Li-ion cells of 3.6 V connected in series to get 14.4 V.
The size of such a pack is nD x mD x H, where n is the number of cells in a row, m is the number of rows, D is the cell diameter, and H is the cell height. Photo of completed multiple row configured cells battery pack below: Nested configurations follow the same connection principles using the same nickel tab material to achieve the design.
If the configuration consists of eight cells with the configuration of 4SP2, two cells are in parallel, and four packs of this parallel combination are connected in series. The total power produced by this pack is 97.92 Wh. The IEC 62133 harmonized the safety requirements for nickel and lithium-based batteries and cells for portable applications.
