In this paper, the equations describing the performance of the electric vehicle are
derived. Performance characteristics for each part in the vehicle system are
obtained when the vehicle is accelerated under voltage, turn on, and turn off angle
control. A comparison between the different methods of control is established.
From these comparisons, it can be noticed that the acceleration time, for the case at
which the turn on angle is controlled, will be smaller than that for the other cases;
also the motor efficiency, at the voltage control method, has the highest value
especially at the higher values of the vehicle speed.
