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.
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
Consider a standard AA alkaline cell. When fresh, it might exhibit an internal resistance of about 0.150 Ω. However, as the battery ages or is subjected to adverse conditions, this value can rise to 0.273 Ω or even higher. This change in internal resistance can significantly affect the battery’s performance.
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.
Ohmic Resistance Lithium Ion Battery internal resistance encompasses various elements hindering the current flow within the battery. Ohmic resistance, a fundamental component, represents the inherent opposition within the battery’s components.
Generally, a lower internal resistance indicates a healthier battery. For example, a good internal resistance for a lead-acid battery is around 5 milliohms, while a lithium-ion battery’s resistance should be under 150 milliohms. One way to measure internal resistance is by using the open-circuit voltage method.
