How does the Audi e-Tron charge its battery?

I'm thinking of purchasing the Audi e-Tron but I'm not sure how the battery charging process works. Can anyone provide some insight?

Hi Samantha, with the Audi e-Tron, you can charge the battery at home using a 120-volt outlet or a 240-volt outlet. You can also charge it at public charging stations using a Level 2 charger. The car also has regenerative braking, which helps to continually charge the battery while you drive. It's a very efficient process!
