The operating voltage of the pack is fundamentally determined by the cell chemistry and the number of cells joined in series. If there is a requirement to deliver a minimum battery pack capacity (eg Electric Vehicle) then you need to understand the variability in cell capacity and how that impacts pack configuration.
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 [-].
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.
The battery pack will be designed for an average energy consumption of 161.7451 Wh/km. All high voltage battery packs are made up from battery cells arranged in strings and modules. A battery cell can be regarded as the smallest division of the voltage. Individual battery cells may be grouped in parallel and / or series as modules.
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.
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):
One illustrative case is to consider two battery pack configurations with the same nominal total pack capacity (230Ah). The first pack configuration has n p =46 cells arranged in parallel, which are then arranged …
