What is electric regenerative braking and how does it work in the Audi e-Tron?

I've been looking into purchasing an Audi e-Tron and have heard about their regenerative braking system. Could you explain how it works and how it benefits the overall driving experience?

Regenerative braking is a system that converts the kinetic energy of your car's momentum into electrical energy to recharge the battery. In the Audi e-Tron, the system uses the electric motor to slow down the vehicle, rather than traditional friction brakes. This not only increases the efficiency of the car, but also reduces wear and tear on the brake pads.
