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

Abstract

In the current research, the autonomy and the energy consumption are the most important attributes expected from the electric road vehicles. Because the electric car manufacturing industry is in a continuous progress, this offers its customers a wide range of constructive variants through which their operational requirements can be met. It also has high expectations of the electric car manufacturers in the current energy context, to develop new high-performance models that can be considered as a real alternative to the current internal combustion engine solutions. So, the research part continues, and is a priority for all car manufacturers. Moreover, the computer simulation is also included as an intermediate stage before the final projects are validated. In the first part, there are detailed theoretical aspects of the electric vehicle to be tested and the test procedure applicable to it, specific to the WLTC cycle, for the high and very high-speed test area. Also, is described the vehicle model simulated using the AMESIM modelling platform. In the second part, are presented the experimental and simulated results performing a comparative analysis. Following the analysis, it has been possible to draw graphs showing the evolution of the state of charge and the mode of exhaustion of the autonomy, in the case of the two driving zones analyzed, respectively at high and very high speed.
