What Is Regenerative Braking?
Regenerative braking is a method of getting back the energy lost during braking and storing it as electricity in the battery.

It converts the motion (kinetic energy) of your car and returns it as electrical power to the vehicle,increasing its efficiency.
Regenerative braking (sometimes shortened to regen) is used in all of the hybrid and battery-electric cars plus a few petrol only powered cars.



How Does It Work?


https://www.youtube.com/watch?v=pqRlkAYLDZs

In a conventional car,a tremendous amount of energy is wasted by the braking system. When you put your foot on the brake,the surface of the brake is pushed against the hub’s spinning disk or drum.Disc and drum brakes do a fine job of stopping the car,but all of the kinetic energy of your car’s momentum is irrecoverably lost to heat from friction.

Electric and hybrid vehicles drive the wheels with an electric motor or multiple motors. When you start to coast,each motor instantly becomes an electrical generator,working to capture the car’s kinetic energy.Operating as generators,they both create a drag on the wheels they're attached to and start producing electricity.

As soon as you depress the brake pedal,the generator is told to increase its power generation,which in turn causes even more resistance,slowing the car.
The electricity generated flows back to the battery pack,where it’s available to help accelerate the vehicle,or power its systems.

When you press the accelerator,the battery provides electricity to turn the motor,which turns the wheels.
When you take your foot off the gas,or apply the brakes,this process goes into reverse.


Battery---->Wheels

Battery<----Wheels


Electricity to the motor is cut and instead the wheels transfer their kinetic energy to the motor,essentially transforming it into a generator to send electricity back to the battery.

Regenerative braking work better at certain speeds than at others.They're most effective in stop-and-go driving situations.So hybrids and fully electric cars also have friction (standard) brakes,as a kind of back-up system in situations where regenerative braking simply won't supply enough stopping power.

ANOTHER AREA REGENERATIVE BREAKING IS FULLY APPLIED IS ON AIRCRAFTS, A FLYING AIRCRAFT HAS NOTHING TO DO WITH FRICTIONAL BRAKES.

You don't need to have a car to appreciate this. Simply add this to your knowledge so when your mates are talking, you won't be left out.

As for not having a car, you dint need to announce your status here. You font have today does not mean tomorrow you would not be donating aeroplanes.

Dint look down on yourselve.
