What EV Charger Do You Need for a 2022 Audi e-tron S?
Forty-eight amps is the correct figure for your car. This setup requires a dedicated Level 2 supply to fill the 95.5 kWh battery overnight. You will get 24 miles of range per hour of charging.
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 3.1 miles |
| EPA rated range | 208 miles |
| Energy for a full charge | about 95.5 kWh at the wall |
Why 48 amps and not more
Your car accepts up to 48 amps of alternating current. Pushing more amperage into the vehicle makes zero sense because the onboard charger maxes out at 11.0 kW. A larger unit will not speed up your recovery time. Sticking to 48 amps feeds the battery at its maximum rated AC intake without wasting money on oversized hardware. Your car takes 8.7 hours to reach a full state from empty at this rate.
What the install involves
You need a 60 amp breaker to feed this load safely. Run heavy copper wire from your electrical panel to the garage wall. Skip the outlet entirely because a 48 amp draw demands hardwiring to prevent thermal damage at the terminals. Bring in a professional to verify spare capacity in your panel and land the circuit properly.
Chargers that match this car

Common questions
- Can I use a standard wall outlet?
- Level 1 charging on a standard household outlet takes 66 hours for a full tank. It adds only 3.1 miles per hour. You need a proper Level 2 setup for daily driving.
- Why does the EPA estimate take longer?
- The EPA rating lists 10.0 hours to fill the battery instead of 8.7 hours. Government test procedures factor in efficiency losses during the conversion process.
- What plug type does the car use?
- Your car uses the standard J1772 connector for all Level 2 AC equipment. Every non Tesla vehicle sold in North America through 2024 relies on this plug format.
- Will a 50 amp charger go faster?
- No. The onboard charger caps your intake at 48 amps regardless of what the supply equipment can handle.
Other vehicles
Charging times derived from EPA data for the 2022 Audi e-tron S (covering 2 EPA trim listings). Electrical requirements follow NEC 625.41, which sizes a circuit at 125% of a continuous load. Always have a licensed electrician verify your panel.
