To calculate the number of cells in a battery pack, both in series and parallel, use the following formulas: 1. Number of Cells in Series (to achieve the desired voltage): Number of Series Cells = Desired Voltage / Cell Voltage 2. Number of Cells in Parallel (to achieve the desired capacity):
Given a number of cells in a battery pack (such as 100 cells), they can be arranged as sets of cells directly in parallel, which are then connected in series (such as a 2P50S battery), or as strings of cells in series, which are then connected in parallel (such as 50S2P).
The total battery pack voltage is determined by the number of cells in series. For example, the total (string) voltage of 6 cells connected in series will be the sum of their individual voltage. In order to increase the current capability the battery capacity, more strings have to be connected in parallel.
Step 3: Calculate the total number of cells: Total Cells = Number of Series Cells * Number of Parallel Cells Total Cells = 7 * 6 = 42 cells So, you would need 42 cells in total to create a battery pack with 24V and 20Ah using cells with 3.7V and 3.5Ah.
Whenever possible, using a single string of lithium cells is usually the preferred configuration for a lithium ion battery pack as it is the lowest cost and simplest. However, sometimes it may be necessary to use multiple strings of cells. Here are a few reasons that parallel strings may be necessary:
The battery pack capacity C bp [Ah] is calculated as the product between the number of strings N sb [-] and the capacity of the battery cell C bc [Ah]. The total number of cells of the battery pack N cb [-] is calculated as the product between the number of strings N sb [-] and the number of cells in a string N cs [-].
