Lead-acid (PbA) batteries have been the main source of low voltage (12 V) applications in automotive systems. Despite their prevalent use in cars, a robust monitoring system for PbA batteries have been lacking over the past century simply because the need for developing such algorithms did not exist .
Lead-acid batteries naturally degrade as they age. One effect of this deterioration is the increase in resistance of the various paths of conductance of the internal cell element. The internal ohmic test units are generally designed to detect this internal change.
There were variations in the internal ohmic readings that were unrelated to the test variables. Based on the preliminary results of this study, it is recommended that internal ohmic readings not be used as the sole acceptance criteria for lead-acid batteries.
Capacity degradation is the main failure mode of lead–acid batteries. Therefore, it is equivalent to predict the battery life and the change in battery residual capacity in the cycle. The definition of SOH is shown in Equation (1): where Ct is the actual capacity, C0 is nominal capacity.
In order to develop a battery health monitoring algorithm, it is of paramount importance to ensure that the algorithm is capable of capturing the effect of all dominant aging mechanism of the battery. There are three major degradation mechanisms concerning PbA SLI, i.e. PAM degradation, corrosion, and negative electrode sulphation.
