Conventional vehicle are gasoline engine type and it content sets of mechanical linkage system where power transfer from engine to wheel, liquefied petroleum fluid is main source required to produce a power.
Ev vehicle is battery operated machine but electric charging is required to store energy so power transfer from electrical system to mechanical system to drive a vehicle.
Gasoline engine generally petrol and Diesel based where electric vehicle based on types of battery and it's alternative sources.
Componant of EV is battery motor current actuators and control.
EV motor types depending upon power output. So basically induction motor magnetic motor DC motor Brushless DC motor etc.
