Do Electric Vehicles Have Engines?

[VanFelix]

Electric vehicles do not have engines; they have electric motors. Electric vehicles complete their operation through the process of battery—current—power regulator—electric motor—power transmission system—driving the vehicle to move. From this process, we can conclude that pure electric vehicles are directly driven by motors that power the wheels. An electric motor is a device that converts electrical energy provided by a power source into mechanical energy. The power source supplies electrical energy to the electric motor, which is the driving mechanism of the electric vehicle. The motor then converts this electrical energy into mechanical energy, either through a transmission system or by directly driving the wheels and working devices. The most widely used power source in electric vehicles is the lead-acid battery. However, due to its relatively low energy density, slow charging speed, and shorter lifespan, lead-acid batteries are being replaced by other types of batteries. Currently developing power sources include sodium-sulfur batteries, nickel-cadmium batteries, lithium batteries, fuel cells, and flywheel batteries. The application of these new power sources has opened up broad prospects for the development of electric vehicles.
