Here's all the charging information that you need to know about the e-tron sportback. At 150 kW charging stations you can get approximately 58 miles of range in 10 minutes and 174 miles in 30 minutes.

Rapid charging

The e-tron Sportback’s 150 kW rapid charging capability when charging at a high speed commerical charger is achieved in large part by a highly flexible thermal management system. This system is comprised of four separate circuits and regulates the temperature of the high-voltage components. In addition to high-speed charging, a long battery life cycle and reproducible performance, even under heavy loads, are significant resulting benefits. The standard heat pump, which harnesses waste heat from the high-voltage battery, can capture up to 3 kW of actual power losses for heating and air conditioning the interior.

The right technology: revolutionary electric engineering overview

  • With buyers of premium vehicles driving an average of about 30 miles per day[1], the Audi e-tron Sportback – with an EPA-estimated range of 218 – is designed for daily usability.
  • The e-tron Sportback joins the previously introduced e-tron SUV by charging at a stand-out 150 kilowatts, at high speed public chargers.
Charging at this speed translates to:

Recently purchased the 2020 Etron Soortback. When I charge at a 150kw or 350kw station at Electrify America, the charge quickly drops to 47-49kw within a few minutes. Is there a cap on the charging speed of the Audi or is this an Electrify America issue? I have had the same result at multiple charging stations in Florida.

@BayArchitect it really depends. Sometimes charging stations may have technical issues and are limited to a lower speed. Ionity here in Europe - sort of a EA equivalent - sometimes throttle their 150kw-350kw stations if there are issues with the charger. Our local one is throttled at 50kw at the moment, on free vend.

Once your Audi is charging beyond 80% state of charge, the charge speed will drop gradually from 150kw to 50kw and less.

If your Audi has a cold battery then it may take a few minutes to get up to the full speed (as long as your state of charge is below 80%).

Otherwise there may be a problem with your car charger/battery or the battery management system in the Audi. If as you say this happens at multiple stations AND at a state of charge less than 80%, then I'd recommend you speak to your Audi dealer to see what's up.
