Abstract: A mathematical model of a lead-acid battery is presented. This model takes into account self-discharge, battery storage capacity, internal resistance, overvoltage, and environmental temperature. Nonlinear components are used to represent the behavior of the different battery parameters thereby simplifying the model design.
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.
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.
Lead-acid batteries have limited dynamic charge-acceptance, especially at high States of Charge (SoC). The absolute amount of charge-acceptance is difficult to predict and depends not only on SoC, temperature, and (to a surprisingly small extent) voltage, but also on short and long-term history.
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.
