What EV Charger Do You Need for a 2022 Audi e-tron GT?
Wiring a garage for Level 2 charging requires a professional to pull a circuit and land it on the breaker. Your 2022 Audi e-tron GT draws 48 amps at 11.0 kilowatts. You need a 48 amp EVSE to feed the car at its maximum onboard charger rate. A licensed electrician must handle this installation.
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 8.9 hours |
| Range added per hour (Level 2) | about 27 miles |
| Full charge on a 120 V outlet | about 68 hours |
| Range added per hour (120 V) | about 3.5 miles |
| EPA rated range | 238 miles |
| Energy for a full charge | about 98.2 kWh at the wall |
Why 48 amps and not more
The car accepts a maximum of 48 amps, so buying a larger charger gives zero speed benefit. Feeding it 48 amps replenishes 27 miles of range every hour. A full battery takes 8.9 hours from empty at this rate. The EPA test rates the car at 24 miles per hour because that testing process does not always run at peak AC rate. Pushing more amperage through the line does not speed up the car because the onboard charger limits intake.
What the install involves
A 48 amp continuous load requires a 60 amp breaker. No household receptacle is rated for this draw, so the unit must be hardwired directly into the circuit. Have an electrician check your panel for spare capacity before buying hardware. They will run heavy gauge copper wire to the wall mount and torque the terminals down. Skipping these steps risks thermal overload.

Common questions
- What connector does the car use?
- Every non-Tesla EV sold in North America through 2024 uses the J1772 connector for AC Level 2 charging. Your car plugs directly into any standard J1772 cord.
- Can I use a standard wall outlet?
- Level 1 charging from a standard household outlet delivers 3.5 miles of range per hour. A full charge takes 68 hours this way, which is far too slow for daily driving.
- Why does the EPA charge time differ from the max rate?
- The EPA rated Level 2 charge time is 10.0 hours instead of 8.9 hours because the EPA test does not always run at the car's peak AC rate. Real-world charging at 48 amps hits the faster time.
- Can I charge at public Tesla stations?
- You can use a Tesla to J1772 adapter to plug into Tesla Destination Chargers and Wall Connectors. These adapters let your J1772 car access destination units.
