1. A computer-implemented method for selecting a velocity profile for an electric vehicle, comprising acts of:
determining a route to be traveled by the electric vehicle based on a starting point and a destination;
determining a plurality of parameter values, the plurality of parameter values comprising:
at least one first parameter value for each of a plurality of road segments in a selection horizon, wherein the selection horizon is associated with the route; and
at least one second parameter value for at least one energy storage device of the electric vehicle;
using the plurality of parameter values to predict a plurality of velocity profiles over the plurality of road segments in the selection horizon, wherein:
each velocity profile of the plurality of velocity profiles is predicted based on a corresponding value of at least one variable relating to a driving style of a driver of the electric vehicle;
computing an energy consumption cost and a travel time cost for each velocity profile of the plurality of velocity profiles; and
selecting, based on the respective energy consumption costs and the respective travel time costs, a velocity profile from the plurality of velocity profiles.
