REGENERATIVE BRAKING SYSTEM

BRAKING METHOD IN WHICH THE MECHANICAL ENERGY FROM THE LOAD IS CONVERTED INTO ELECTRIC ENERGY AND REGENERATED BACK INTO THE LINE IS KNOWN AS REGENERATIVE BRAKING. THE MOTOR OPERATES AS GENERATOR

NECESSITY OF THE REGENERATIVE BRAING SYSTEM



IN LOW-SPEED, STOP-AND-GO TRAFFIC WHERE LITTLE DECELERATION IS REQUIRED; THE REGENERATIVE BRAKING SYSTEM CAN PROVIDE THE MAJORITY OF THE TOTAL BRAKING FORCE. THIS VASTLY IMPROVES FUEL ECONOMY WITH A VEHICLE, AND FURTHER ENHANCES THE ATTRACTIVENESS OF VEHICLES USING REGENERATIVE BRAKING FOR CITY DRIVING.

AT HIGHER SPEEDS, TOO, REGENERATIVE BRAKING HAS BEEN SHOWN TO CONTRIBUTE TO IMPROVED FUEL ECONOMY – BY AS MUCH AS 20%.


WORKING


Regenerative Braking System is the way of slowing vehicle by using the motors as brakes. Instead of the surplus energy of the vehicle being wasted as unwanted heat, the motors act as generators and return some of it to the overhead wires as electricity.

The vehicle is primarily powered from the electrical energy generated from the generator, which burns gasoline. This energy is stored in a large battery, and used by an electric motor that provides motive force to the wheels.
