A METHOD AND SYSTEM FOR METHOD FOR ESTIMATING A PRESENT ENERGY CONSUMPTION OF AN ELECTRICALLY PROPELLED VEHICLE

The invention relates to a method for estimating a present energy consumption of an electrically propelled vehicle (1) powered by a propulsion battery (2), the method comprising: obtaining (S102) previous energy consumption values (ECt-1, ECt-2, ECt-3) for a set of previous time instants (t-1, t-2, t-3), and a present drive pattern parameter value; estimating (S104) a present energy consumption (ECt) based on a weighted moving average model (5) fed with the energy consumption values, wherein, the weighted moving average model includes a modelled gain factor for each of at least a portion of the previous energy consumption values, where the modelled gain factors are modelled as a function of the drive pattern parameter.
