What is regenerative braking and how does it affect the range of the Audi e-Tron?

I've heard about regenerative braking being a feature of electric vehicles, but what does it do and how much of an impact does it have on the range of the Audi e-Tron?

Regenerative braking is a system that captures the kinetic energy generated by braking and converts it into electricity, which is then stored in the battery. This means that when you are slowing down or braking, the e-Tron is actually recharging its battery, increasing its range. So, it actually has a positive impact on the range of the e-Tron.
