AI Customer ServiceIn a parallel circuit, the total current of the battery pack is the sum of the currents through each individual branch. If the current through each battery cell is I cell = 2 A and there are 3 cells connected in parallel (N p = 3), the battery pack current is calculated as: I pack = N p · I cell = 3 · 2 = 6 A
If each cell has the same resistance of R cell = 60 mΩ, the internal resistance of the battery pack will be the sum of battery cells resistances, which is equal with the product between the number of battery cells in series N s and the resistance of the cells in series R cell. R pack = N s · R cell = 3 · 0.06 = 180 mΩ
The internal resistance of the battery pack is made up of the cells, busbars, busbar joints, fuses, contactors, current shunt and connectors. As the cells are connected in parallel and series you need to take this into account when calculating the total resistance.
Given that all battery cells are identical and have the following parameters: I cell = 2 A, U cell = 3.6 V and R cell = 60 mΩ, applying the equations used in series and parallel battery cells connections, the current, voltage and resistance of both battery pack configurations are calculated as: I pack = N p · I cell = 2 · 2 = 4 A
When connecting two battery cells in parallel, you should be able to calculate the equivalent internal resistance using the formula 1 R = 1 r1 + 1 r2. This is because the total resistance is the sum of the individual resistances.
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):
