Abstract :
In this paper, we present a model for a 100 Ah high-energy-density Lithium Polymer (Li-Po) battery, using impedance spectroscopy measurements. This model, based on an equivalent circuit approach, is characterized by its simplicity. At the same time it takes into account several important phenomena that occur in lithium battery, such as the dependence of the open-circuit voltage and part of the internal resistance on the state of charge and the temperature. Simulation results are presented and validated using the real current profile of a fleet of electric mail-delivery vehicles.
