Evaluation of the Energy Efficiency of a Fleet of Electric Vehicle for Eco-Driving Application

In this paper, an approach to evaluate the energy efficiency of an electrical vehicle during a short trip is addressed. This approach provides metrics that can be used to evaluate the potential of improvement achievable via intelligent eco-driving techniques and the performance actually achieved by any of them. It can be the basis for an evaluation of a fleet of vehicles and of a whole city for which an energy efficiency map could be derived, depending for instance of traffic management strategy. Experimental data are provided to illustrate the approach for a fleet of electric vehicles in an urban environment. The methods proposed are intended to be the basis of a driver assistance system oriented to optimal eco-driving.
