The reduction of greenhouse gas emission is necessary to limit the global warming. Electrification of the transport sector is one solution. To accelerate the change, accurate and fast simulation program are one of the key issues. The choice of the accurate model is an important aspect to the simulation program. In this paper, different models of an electric drive for an electric vehicle are compared in terms of computation time and energy consumption. A static model will lead to divide the computation time by 100, by losing only 2% of accuracy
