How does Audi's e-Tron charging station work?

I recently purchased an Audi e-Tron and I'm wondering how the charging station works. Do I need to install a special outlet or can I use a regular power outlet? Will it affect my electricity bill?

The Audi e-Tron can be charged from a regular household outlet using a charging cable included with the car. However, for faster charging, it is recommended to install a Level 2 charger, which requires a 240 volt outlet. This may increase your electricity bill slightly, but overall, the cost is still significantly lower than refueling a gas-powered vehicle.
