How does the Audi e-Tron recuperation system work and what benefits does it offer?

I have read about the Audi e-Tron's recuperation system, but I am still unclear on exactly how it works and what advantages it brings. Can someone please explain it to me in detail?

The Audi e-Tron's recuperation system uses its electric motors to recover energy that is normally lost during braking or coasting. This energy is then stored in the battery for later use, which improves overall efficiency and range. It also allows for one-pedal driving, as the car can come to a complete stop using the recuperation system instead of the brakes.

In addition to improved efficiency, the recuperation system also offers a smoother and more controlled driving experience. This is because the deceleration caused by the recuperation system is more gradual and adjustable compared to traditional braking methods. As a bonus, your brake pads will also last longer.
