An electric car, as the name suggests, is a type of vehicle that moves by the power of batteries instead of liquid fuel such as diesel or gasoline. The concept is very old but it has gained momentum of late due to factors such as the need for green automobiles, cheaper means of transport and sheer innovation.
By mere observation, an electric car looks like any other car but a close examination of its motive power and engine system will reveal a different set of components.
The electric car is mainly made up of an electric motor, a controller and a set of batteries.
The electric motor moves the car just like the motor in a starter makes it turn. It is the main means through which the car is able to move around. 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 foot from the power, resulting in low speed for the vehicle. The controller also ensures that as soon as the driver steps on the brakes, acceleration is automatically reduced.
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 not simply full or no acceleration. In these cases, the controller will intelligently monitor the press of the pedal and supply the necessary current accordingly.
The set of batteries provide the power for the moo to turn to make the car move.
An electric car uses minimal mechanical systems and is therefore quiet and smooth in movement.
