In this paper a conception, modelling and simulation tool for drive system of the prototype electric vehicle "ELV001" have been presented. The design and building of this vehicle have been carried out in frame of the project: "Building a market of electric vehicle and charging infrastructure - fundamentals of energy safety". The simulation tools are of great assistance to engineers and researchers to reduce product-development cycle time, improve the quality of the design, and simplify the analysis without costly and time-consuming experiments. The presented simulation tool has been developed using the system simulator Synpsys/Saber software. This user-friendly simulation package is able to simulate electric/electronic circuits and mechanical modules; i.e., it has capability for simulating the entire system of an automobile. Chosen simulation results of the electric vehicle "ELV001" has been presented.
