What EV Charger Do You Need for a 2022 Audi e-tron S Sportback?
A full charge takes 8.7 hours at the maximum rate. That window fits neatly into a standard night of sleep. You need a 48 amp Level 2 setup to hit that speed.
The numbers
| Maximum AC charging rate | 11.0 kW (48 A) |
|---|---|
| Charger size to buy | 48 A |
| Circuit breaker required | 60 A |
| Outlet / connection | hardwired (a 48 A EVSE must be hardwired -- no household receptacle is rated for it) |
| Charge port | J1772 |
| Full charge on Level 2 | about 8.7 hours |
| Range added per hour (Level 2) | about 24 miles |
| Full charge on a 120 V outlet | about 66 hours |
| Range added per hour (120 V) | about 3.2 miles |
| EPA rated range | 212 miles |
| Energy for a full charge | about 95.2 kWh at the wall |
Why 48 amps and not more
The car accepts a maximum of 48 amps for alternating current charging. Buying a larger unit will not speed up the process because the onboard charger limits the intake. Pushing 48 amps delivers 11.0 kilowatts to the 95.2 kilowatt hour battery. Going down to a smaller breaker leaves you waiting longer every morning. Match the supply equipment to the vehicle limit.
What the install involves
A 48 amp electric vehicle supply equipment unit requires a 60 amp breaker. No household receptacle is rated for this load, so you must hardwire the unit directly. Call a licensed professional to run heavy gauge copper wire from your panel to the garage wall. They will land the circuit on a dedicated double pole breaker and verify your main service has enough spare capacity.

Common questions
- Can I use a standard wall outlet?
- Plugging into a regular household socket gives you Level 1 speeds. That method adds 3.2 miles of range per hour and takes 66 hours to refill the battery from empty.
- What connector does the car use?
- Every non Tesla vehicle sold in North America through 2024 uses the J1772 connector for AC Level 2 charging. The port on your fender matches this standard directly without needing special adapters.
- Why does the EPA charge time differ from the peak rate?
- The EPA rating estimates 10.0 hours for a full charge because federal test cycles do not always run at the absolute peak alternating current rate of the vehicle. Real world charging at 48 amps completes the job in 8.7 hours.
- Will a 50 amp charger work?
- Units like the ChargePoint Home Flex can deliver 50 amps, but your car maxes out at 48 amps. You will only draw what the vehicle onboard hardware allows.
