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.
Lead–acid batteries are the most common rechargeable battery type in the world, and in the U.S. 17% of the market share of lead–acid batteries is related to energy storage systems . In commercial UPSs, lead–acid batteries are dominant at various power ranges , , , , , , .
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.
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 method is based on a circuit model and the learning of the discharge characteristic (voltage and current) of the battery. The prediction of terminal voltage is achieved by successive curve fittings in real time, made with a Levenberg–Marquardt algorithm (LMA) . As a result, the developed method has high adaptability.
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.
