Comparison of two levels of cell models for an EV current cycle
Résumé
This paper studies the effect of the granularity of a
cell model on the voltage accuracy. A multi-coupled cell model
with varying parameters is compared with a simpler one
(varying voltage source and equivalent series resistance). The
first model implies a very long and complex characterization
process. The second one is very simple. Experiments are
performed at different temperatures by applying a current
profile corresponding to a driving cycle of an electric vehicle.
Experimental results show both models can be used for 25°C
and 10 °C ambient temperatures with reasonable accuracy.
Nevertheless, when the temperature is cold the multi-coupled
model is more accurate.
