1. A method for estimating a present energy consumption of an electrically propelled vehicle powered by a propulsion battery, the method comprising:
obtaining previous energy consumption values for a set of previous time instants, and a present drive pattern parameter value; and
estimating a present energy consumption based on a weighted moving average model 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 non-linear functions of the drive pattern parameter.
