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.
Lead-acid (PbA) batteries are one the most prevalent battery chemistries in low voltage automotive applications. In this work, we have developed an equivalent circuit model (ECM) of a 12V PbA battery while preserving the major dynamics of a semi-empirical model we have developed previously.
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 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.
Two novel state of health estimation algorithm for lead acid batteries are presented. An equivalent circuit model is used to estimate the battery capacity. A fast Fourier transform based algorithm is used to estimate cranking capability. Both algorithms are validated using aging data.
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.
