AI Customer ServiceThe 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.
High internal resistance in a pack can make it less efficient, reduce its range, and create too much heat in EVs, which can be dangerous and shorten the battery’s life. Therefore, calculating and reducing the internal resistance of battery packs is crucial in designing efficient, safe, and long-lasting battery systems.
Yes, you can measure the internal resistance of any type of battery using the same method. However, keep in mind that the internal resistance may vary depending on the battery chemistry and its state of charge. What precautions should I take when measuring the internal resistance of a battery?
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
A key factor in the design of battery packs is the internal resistance Rint [Ω] . Internal resistance is a natural property of the battery cell that slows down the flow of electric current. It’s made up of the resistance found in the electrolyte, electrodes, and connections inside the cell.
