Regenerative Braking Systems

There are many different types of braking systems that are used in cars, one of them being regenerative brakes. Each braking system in a conventional vehicle for instance produces friction, thus eventually bringing the car to a stop; the regenerative braking system, mainly used in an electrical vehicle / hybrid however, does more than simply stop a car. Like any other braking system, the regenerative brakes are made up of components that all contribute to the deceleration of a car (some of which are not as important as the other), and have also revolutionised the performance, safety and efficiency of each vehicle in the modern world.

The regenerative braking system
A basic overview of the function of the entire regenerative braking system may be, as the hybrid / electric vehicle slows down, the electric motor recuperates kinetic energy and converts it into electricity, which then regenerates the battery for reuse, whereas in a conventional vehicle the kinetic energy from friction braking is converted into heat and emitted into the environment as unused. This charged battery in turn powers the vehicle’s electric traction motor; in an electric vehicle this motor is considered to be the core source of locomotion (to move from one place to another). The regenerative braking system consists of many components, all of which have different functions. The most significant components that contribute to the braking of hybrids / electric cars are the electric motor, drivetrain, battery and the motor controller.

How it’s components work
A more technical analysis of the regenerative braking system’s components may be, as the driver of the Hybrid or electric vehicle applies force on the brake pedal, the electric motor is switched to generator mode (where kinetic energy is turned into electricity, then sent to the high-voltage battery as storage for reuse). The wheels on the rear of the vehicle transfer the kinetic energy by the...
