What are the benefits of Audi e-Tron's regenerative braking system?

I've heard that Audi e-Tron has a regenerative braking system. Can you explain how it works and what benefits it provides?

Regenerative braking is a feature in electric vehicles where the brakes convert the kinetic energy from deceleration into electrical energy, which is then stored in the battery. This helps to increase the vehicle's range and also reduces wear and tear on the brakes.

Using regenerative braking can also improve the driving experience by providing a smoother and more controlled deceleration. It can also potentially reduce the need for frequent brake replacements, saving you money in the long run.
