The challenges for modeling and simulating lead–acid batteries are discussed in Section16.3. Specifically, the manifold reactions and the changing parameters with State of Charge (SoC) and State of Health (SoH) are addressed.
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.
During the lifetime of a lead–acid battery, aging mechanisms affect its electrical performance. These mechanisms influence the behavior under open-circuit conditions and under load. For any electrical model, the values of the resistances and capacities change over time due to aging.
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 work of Lander in the 1950s is a baseline for the description of corrosion processes in the lead–acid battery. The development of microscopic models began in the 1980s and 1990s. For instance, Metzendorf described AM utilization, and Kappus published on the sulfate crystal evolution.
