Customer ServiceThe 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.
There are two different approaches followed in the battery industry to measure the internal resistance of a cell. A short pulse of high current is applied to the cell; the voltages and currents are measured before and after the pulse and then ohm’s law (I = V/R) is applied to get the result.
Battery internal resistance is a crucial parameter that determines the performance and efficiency of a battery. It is the measure of opposition to the flow of current within the battery due to various factors such as the electrolyte, electrodes, and connections.
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
Several factors contribute to the internal resistance of a battery. These include: Electrode materials: The materials used for the electrodes, such as the active materials and current collectors, influence the internal resistance. The conductivity and surface area of the electrodes play a significant role in determining the resistance.
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.
