Abstract

A lead-acid battery model was developed for use in characterizing lead-acid battery performance for renewable energy power generation and load balancing. This model includes the effect of temperature, current, and state of charge (SOC). The model was tested against experimental results for constant power discharge. This model also shows a strong link between the applied dc current and the effective impedance of the cell.
