Research concerning the autonomy of the electric vehicles, simulated and measured, in the case of driving at the low and the medium speed, specific to the WLTC test.

Abstract

The most important attributes expected from today’s electric vehicles are the electricity consumption and the autonomy, which must be able to unequivocally replace the results achieved by the vehicles equipped with an internal combustion engine. These expectations come equally from the car manufacturers and from the end users. Based on these premises, in a first part of the paper, are presented the theoretical aspects concerning the test procedure for determining the autonomy of electric vehicles, applicable at the European level, with the highlighting of the low and medium driving zones, specific to the WLTC test. Also, are indicated theoretical details regarding the model of the electric vehicle tested and simulated, using the AMESIM modelling and simulation platform. In the second part are presented the comparative results obtained by measuring and simulating regarding the electric autonomy, respectively the influence that the driving at the low and the medium speed has, upon of the state of charge depletion of the traction battery.
