What is the difference between electric vehicles and petroleum fuel vehicles?

Electric vehicles draw energy from batteries where electrical energy is stored. The energy source of oil-fueled vehicles is fossil fuels such as gasoline, diesel and LPG (liquefied petroleum gas). Electric motors that convert electrical energy into motion energy are used in electric vehicles, and internal combustion engines are used in petroleum fueled vehicles.

In electric vehicles, motors create circular motion. In this way, the movement created by the electric motor can be transferred directly to the wheels. In internal combustion engines, the linear motion of the pistons is converted into circular motion using different systems.

The rotational speed of electric motors ranges from 0-18,000 rpm (rotations per minute), and electric motors can produce power with high efficiency at different rotating speeds. Internal combustion engines, on the other hand, produce maximum power within a certain speed range - mostly at high speeds. For this reason, in vehicles with internal combustion engines, a transmission system is needed to efficiently transfer the power produced by the engine to the wheels. In vehicles using electric motors, the energy supplied from the batteries is controlled and the speed and torque generated by the motor are changed.
