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
A key parameter to calculate and then measure is the battery pack internal resistance. This is the DC internal resistance (DCIR) and would be quoted against temperature, state of charge, state of health and charge/discharge time. Symbolically we can show a cell with the internal resistance as a resistor in series.
Since weld anomalies will prevent the battery pack from delivering its full level of performance, it is recommended to test assembled battery packs using a battery tester. The Hioki BT3562 can measure the internal resistance of battery packs of up to 60 V, while the BT3563 can measure the internal resistance of battery packs of up to 300 V.
Assuming 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, calculate the following parameters of the battery pack: current, voltage, internal resistance, power, power losses and efficiency.
The resistance of a battery pack depends on the internal resistance of each cell and also on the configuration of the battery cells (series or parallel). The overall performance of a battery pack depends on balancing the internal resistances of all its cells.
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
