How does the efficiency of regenerative braking affect the driving range of the Audi e-Tron?

I have heard that the e-Tron has an advanced regenerative braking system. Can someone explain how this system works and how it affects the overall driving range of the vehicle?

The regenerative braking system in the e-Tron uses the electric motors to generate electricity while braking, which is then used to recharge the battery. This can increase the driving range by up to 30% in stop-and-go traffic.

The more efficient the regenerative braking system is, the more energy it can recapture and the longer the driving range will be. So, it is important to use lower levels of regenerative braking when driving on highways to maximize range.
