Description
Summary:The driving range of electric vehicles is an important issue. The velocity profile can have an important impact on their energy consumption and thus their driving range. In this paper, a commercial electric vehicle is studied. The model of its traction subsystems is developed using a forward approach. A specific driving cycle generator is then coupled with this model. A feedback from the model to the generator allows for recalculation of the velocity reference in case of a limitation due to the electrical drives, for a more accurate estimation of energy consumption. Different trips are then studied with this method. The maximal velocity has a strong impact on the energy consumption while the maximal acceleration has a low impact.
