Do lead-acid batteries change internal resistance under different current?
Taking three full charging lead-acid batteries with a similar performance to discharge, as shown in Fig. 4, the change of internal resistance under different current for discharging has the same trend. Obviously, the battery internal resistance increases faster along with the enhancement of discharging current.
What is internal resistance in a lead acid battery?
As the capacity of lead acid battery decreased or the battery is aged, its internal resistance will be increased. Therefore, the internal resistance data may be used to evaluate the battery’s condition. There are several internal resistance measurement methods, and their obtained values are sometimes different each other.
Does a lead-acid battery increase charge transfer resistance?
SOH is reflected by changes in the impedance of a lead-acid battery during operation. Hypothesis that the increase of the impedance is sufficient for the estimation of the available capacity was presented in . The study explained increase of the charge transfer resistance during the battery ageing.
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.
