How does the regenerative braking in Audi e-Tron work?

I'm curious about the regenerative braking system in the Audi e-Tron. Can someone explain how it works and how efficient it is in terms of battery regeneration?

The Audi e-Tron uses a combination of regenerative braking and physical brakes to slow down the car. When the brake pedal is pressed, the electric motor acts as an alternator, converting kinetic energy into electrical energy to be stored in the battery.

Not only is regenerative braking efficient in terms of battery regeneration, but it also helps with preserving the physical brakes. The regenerative braking system in the Audi e-Tron provides a seamless and comfortable driving experience while also increasing the lifespan of the brakes.
