What are brakes?
A brake is a device that decelerates a moving object / prevents an object from accelerating.
Brakes use friction to convert kinetic energy into heat
When the brake is pushed the caliper containing piston pushes the pad towards the brake disc which slows the wheel down.
Convectional braking system
Conventional braking systems use friction to counteract the forward momentum of a moving car.
As the brake pads rub against the wheels, excessive heat energy is created.
This heat energy dissipates into the air, wasting up to 30% of the car's generated power
Regenerative braking
A regenerative brake is an energy recovery mechanism which slows a vehicle by converting its kinetic energy into another form of energy.
The energy can be either used immediately or stored until needed.
How does it works?
When the driver steps on the brake pedal of an electric or hybrid vehicle, these types of brakes put the vehicle's electric motor into reverse mode, causing it to run backwards, thus slowing the car's wheels.
While running backwards, the motor also acts as an electric generator, producing electricity that's then fed into the vehicle's batteries.
The battery supply the power when the vehicle need.
Benefits of regenerative braking
Reduction of pollution
Increase in engine life
Breaking is not total loss
