ANALYSIS OF A CONVERTED ELECTRIC CAR IN DYNAMIC MODES

Vasil Dimitrov, Atanas Nikolov

The report examines a converted electric car Audi A2, a light and aerodynamic model, for which a suitable induction motor was selected, the range at different gears and driving speed is calculated for two types of batteries. An analysis of four dynamic acceleration modes of the electric car was carried out, calculating the acceleration with gear shifting at two different induction motor rotation frequencies and two acceleration modes without gear shifting. Based on mileage and dynamics studies, the way of the gearbox using can be optimized, or it can be replaced with a reducer an appropriate gear ratio. The methodology presented in the report can be used when converting cars to electric, both for choosing a suitable car and electrical drive, and for optimizing the mechanical part of the electric car, to obtain increased energy efficiency, high operational reliability and compliance with the ments for electromagnetic compatibility, according to modern IEC standards.
