2. Lead Acid Battery Modeling 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: V dis = E0 K Q Q (1)it (it+i )+Vexp Rint i = E0 V pol
For a nominal 12V and 200A car battery the model could be something like this: - Capacity 200Ah - Minimum battery voltage 11V (fully discharged) - Maximum battery voltage 13.5V (fully charged) Thus, the model can be constructed as follows: - DC voltage: 11V.
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.
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.
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 lead–acid system is thermodynamically unstable. The two most relevant side-reactions for commercial batteries are corrosion of the positive current-collector (highlighted) and electrolysis of water (highlighted). In valve-regulated lead–acid batteries (VRLA), recombination of oxygen is also a relevant process influencing the potentials at both electrodes.
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.
The Depth of Discharge (DoD) in a lead-acid battery is calculated as DoD = 1 – State of Charge (SoC). In lead-acid batteries, many different effects with different time constants occur.
