Benefit of the model
The model enables circuit designer to predict and optimize LeadAcid battery runtime and circuit performance.
The model can be easily adjusted to your own Lead-Acid battery specifications by editing a few parameters that are provided in the datasheet.
The model is optimized to reduce the convergence error and the simulation time.
This Lead-Acid Battery Simplified SPICE Behavioral Model is for users who require the model of a Lead-Acid Battery as a part of their system.
The model accounts for Battery Voltage(Vbat) vs. Battery Capacity Level (SOC) Characteristic, so it can perform battery charge and discharge time at various current rate conditions.
As a simplified model, the effects of cycle number and temperature are neglected.
The model is characterized by parameters: C which represent the battery capacity and SOC which represent the battery initial capacity level. Open-circuit voltage (Voc) vs. SOC is included in the model as an analog behavioral model (ABM).
• NCells (Number of Cells in series) is used when the Lead-acid cells are in series to increase battery voltage level.
