The lead-acid model has been proposed and explained in [ 21 ]. The Shepherd relation is the simplest and most popular battery model [ 7 ]. It defines the charging and discharging phases’ nonlinearity. The discharge equation for a Lead acid battery is as follows:
When modelling lead–acid batteries, it's important to remember that any model can never have a better accuracy than the tolerances of the real batteries. These variations propagate into other parameters during cycling and ageing.
Conclusions This article suggests a recent method for identifying lead-acid battery parameters. This method updates the battery model with unknown parameters employing the metaheuristic algorithm algorithms. The identification compares the model output with actual measured data, and RMSE is utilized as an objective function.
A lead–acid battery has two main characteristics: the thermodynamic equilibrium voltage U0 and the complex battery impedance. These characteristics are represented in a basic Electrical Equivalent Circuit (EEC). When a discharge (load) or charge current flows through the terminals, voltage drops (overvoltages) across the impedance terms are added to U0.
The findings approve that the suggested identification method is excellent at precisely estimating the parameters of a lead-acid battery. In addition, the proposed method proved highly accurate compared to various algorithms and three testing cases. Conceptualization, H.R. and S.F.; methodology, H.R.,
