What is Regenerative Braking? 

Regenerative braking is a technology used in electric and hybrid vehicles to capture and reuse energy that would otherwise be lost during braking.

How Does It Work?

1. Normal Braking: In a traditional vehicle, when you brake, the car’s kinetic energy (the energy it has while moving) is turned into heat and wasted.
2. Regenerative Braking: 

• In cars with regenerative braking, when you press the brake pedal, the electric motor runs in reverse.
• This reverse action slows down the car, just like traditional brakes.
• Instead of converting kinetic energy into heat, the motor converts it back into electrical energy.
• This electrical energy is then stored in the vehicle’s battery for later use.

1. Energy Conversion: This reversed motor converts the kinetic energy of the moving car into electrical energy.
2. Energy Storage: The electrical energy produced is sent back to the car’s battery and stored for future use, such as powering the vehicle or running electrical systems.

Significance:

• Energy Efficiency: Saves energy by reusing it, reducing the need for frequent battery recharges.
• Extended Range: Helps electric and hybrid vehicles travel further on a single charge.
• Less Wear and Tear: Reduces wear on traditional brake components, leading to lower maintenance costs.

Example: Imagine riding a bicycle down a hill. Normally, if you press the brakes, you slow down and the energy goes away as heat. But if you could somehow capture that energy and use it to help you pedal back up the hill, that would be similar to what regenerative braking does in a car.
