International audience. This paper studies the effect of the granularity of acell model on the voltage accuracy. A multi-coupled cell modelwith varying parameters is compared with a simpler one(varying voltage source and equivalent series resistance). Thefirst model implies a very long and complex characterizationprocess. The second one is very simple. Experiments areperformed at different temperatures by applying a currentprofile corresponding to a driving cycle of an electric vehicle.Experimental results show both models can be used for 25°Cand 10 °C ambient temperatures with reasonable accuracy.Nevertheless, when the temperature is cold the multi-coupledmodel is more accurate.
