Abstract

In an EV (Electric Vehicle), the more tractive force produced by the electric powertrain in fact requires more electric current from the battery. The question is how efficiently the stored energy is used, as for modern EVs, the ability to move over a greater distance represents an important issue. Of course, it can be best confirmed by physical measurements on the vehicle, but before, the analytic calculations and the simulations are important to certify the choices. In this context, the actual paper presents the analysis of the capabilities of a BLDC motor powertrain. A new method is used in the determination of the number of identical motors needed to participate in the powertrain, based on the efficiency map of the individual motor.
