6 FAQs about [The role of the internal resistance of the lead-acid battery]

What is the internal resistance of a lead-acid battery?

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.

What is a good internal resistance for a 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. What is the average internal resistance of a battery? The average internal resistance of a battery varies depending on the type and size of the battery.

Why do batteries have a fixed electrical resistance?

While the grid, welds, and tabs of the battery will have a fixed electrical resistance for a given battery (barring large temperature fluctuations or corrosion with age), the resistance of the electrode materials will be a function of SoC, which increases throughout formation.

What determines the internal resistance of a battery?

Each of the different phenomena itself may depend on the battery state (SoC and temperature), load (current) and short-term history (length of rest period, charging and discharging). The observed internal resistance strongly depends on the applied measurement technique.

Why should you use a battery internal resistance chart?

By using a battery internal resistance chart, you can easily monitor the internal resistance of your battery and identify any potential issues before they become a problem. Remember, a lower internal resistance indicates a healthier battery, while a higher internal resistance indicates a bad battery that needs to be replaced.

How does the resistance of lead acid change with discharge?

The largest changes occur between 0% and 30% SoC. The resistance of lead acid goes up with discharge. This change is caused by the decrease of the specific gravity, a depletion of the electrolyte as it becomes more watery. The resistance increase is almost linear with the decrease of the specific gravity.
