How do regenerative brakes work in the Audi e-Tron?

I've heard that the Audi e-Tron has regenerative brakes, but I'm not sure how they actually work. Can someone explain the technology behind them?

Regenerative brakes in the Audi e-Tron use an electric motor to convert kinetic energy into electricity, which is then stored in the battery.

By using regenerative brakes, the Audi e-Tron is able to extend its range and reduce wear on the traditional brakes.

Unlike traditional brakes, regenerative brakes in the Audi e-Tron do not generate excess heat, making them more efficient and environmentally friendly.
