AI Customer ServiceThe internal resistance (IR) of a battery is defined as the opposition to the flow of current within the battery. There are two basic components that impact the internal resistance of a battery; they are electronic resistance and ionic resistance. The electronic resistance plus the ionic resistance will be referred to as the
If the internal resistance of the battery cell is not provided by the manufacturer, as we’ll see in this article, using the discharge characteristics of the battery cell, we can calculate the internal resistance of the battery cell, for a specific state of charge value.
Here’s a step-by-step guide to calculating the internal resistance of a battery: Measure the Open-Circuit Voltage (VOC): This is the voltage of the battery when no load is connected. Use a multimeter for accurate results. Connect a Known Load: Attach a known resistor to the battery.
The internal resistance of a battery increases as the state of charge decreases. This is because as the battery discharges, the chemical reactions that produce the electrical energy become less efficient, which increases the resistance of the battery. What is the typical internal resistance of a 1.5V battery?
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.
For example, a high-capacity NiMH battery cell designed for use in an electric vehicle may have an internal resistance of around 1000 mΩ, while a high-rate discharge NiMH battery may have an internal resistance of around 2000 mΩ.
