Modeling of the Operation of an Asynchronous Electric Drive of an Electric Vehicle in Slip Modes

Abstract

Mathematical and computer models of the asynchronous electric drive of an electric vehicle with a detailed mechanical part, taking into account the mechanical differential, are constructed to study dynamic processes while reducing the coefficient of friction of one or two wheels with a road surface. Computer simulation of dynamic processes in the electric drive during a collision, as well as pulling away on the road surface with a reduced coefficient of friction, was carried out. The analysis of the obtained time diagrams was carried out. The analysis showed the adequacy of transient processes and their accordance to physical laws. As a result of the analysis, standard changes in the values were defined that allow us to identify the decrease in the coefficient of friction, which in the future will minimize slippage in hazardous areas by means of a controlled electric drive.
