2019 Audi e-tron quattro - In North America, when plugged into a conventional 240-volt charger delivering 9 kilowatts, a full charge will take 10 hours. Plugging the car to a faster 50-kW DC charger can provide an 80 percent charge in 80 minutes. If the charger delivers 100 kilowatts, that time is halved to 40 minutes.
