Much research on battery internal resistance has been carried out to improve the accuracy of battery SOC estimation and the reliability of battery. As we know, lead-acid battery resistance is divided into three parts: ohmic resistance, electrochemical resistance, and concentration polarization resistance.
Lead acid batteries typically have an internal resistance around 20 milliohms. Thanks Crosstalk for replying me. You said 20 mOhms for a typical lead acid battery. But what is the typical ? 20, 40 or 100Ah ? (12V). I'm not 100% sure on this, but I don't think that the battery's capacity matters.
You can reduce the internal resistance of a battery by using a larger battery or by using a battery with a lower internal resistance. You can also use a battery with a higher voltage or by using a battery with a higher capacity. What is the acceptable internal resistance for a 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?
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.
Factors affecting a battery’s ability to act as an ideal voltage source include: Age of the battery: Older batteries tend to have higher internal resistance. Temperature: Extreme temperatures can affect the internal chemistry, leading to increased resistance. State of charge: A battery’s internal resistance can vary depending on its charge level.
