Abstract:

In this paper, a methodology for the parametrization of a battery equivalent circuit model (ECM) based on capacity and pulse tests is presented. The model can be extrapolated to different battery technologies, and was validated by comparing simulations and experimental tests with lead-acid and lithium-ion batteries. The results show that the model can be used to represent the real behavior of different energy storage technologies and different aging states. In the present study, lithium-ion and lead-acid batteries were analyzed due to their current widespread use.
