What is regenerative braking on the Audi e-Tron?

I've heard that the Audi e-Tron has regenerative braking capabilities. Can you explain what this means and how it works?

Regenerative braking is a feature that allows the electric motor in the Audi e-Tron to act as a generator, converting the kinetic energy of the vehicle's motion back into electricity to recharge the battery. This helps to increase the vehicle's range and also reduces wear and tear on the brakes.

Regenerative braking is similar to the engine braking on a traditional car, except it uses the electric motor to slow down the vehicle instead of the brakes. This feature not only improves efficiency, but also provides smoother braking and enhances the driving experience.
