Some of the most important objectives expected of today’s electric vehicles, as well as from manufacturers and end-users, include electricity consumption, autonomy, which should be able to unequivocally substitute the results obtained by vehicles equipped with a thermic energy source. Based on these premises, a first part of the paper, presents aspects of the current testing methods applicable to electric vehicles, in order to calculate the electricity consumption and also in order to calculate the autonomy, respectively the World-wide harmonized Light duty Test Cycle, characterized by the four driving zones at low, medium, high and very high speed that the electric vehicle has to comply with. In the second part of the paper, as a result of testing the electric vehicle under research on the dynamometer bench, it is highlighted the specific areas from the test cycle, where the traction battery autonomy shows a significant decrease.The analysis of the evolution of the autonomy is corroborated with the acquisition of data from the main electronic control units of the electric propulsion system.
