An electric car, as the name suggests, is a type of vehicle that runs on battery power instead of liquid fuel such as diesel or gasoline. The concept is very old but has gained momentum of late due to factors like the need for green automobiles, cheap means of transportation and sheer innovation.
From mere observation, an electric car looks like any other car, but a close examination of its driving force and engine system reveals a different set of components.
The electric car is mainly composed of an electric motor, a controller and a set of batteries.
The electric motor turns the car in the same way as the motor in the starter turns it. It is the main means through which the car is able to move. The controller is a set of devices that monitors and supplies power to the motor.
The controller basically manages the acceleration; Transmitting less voltage as the driver releases his leg from power, resulting in a lower vehicle speed. The controller also ensures that acceleration is automatically reduced as soon as the driver steps on the brakes.
The controller acts like a switch, turning the battery supply on and off. But it is more than that. A driver may have different levels of acceleration and may only have full or no acceleration. In these cases, the controller will intelligently monitor the presses of the pedal and supply the required current accordingly.
The set of batteries provide the power to move the mu to make the car move.
An electric car uses a minimum of mechanical systems and is therefore quieter and smoother in motion.
