What EV Charger Do You Need for a 2022 Audi e-tron?
Forty-eight amps is the magic number for the Audi e-tron. It matches the onboard charger limit exactly. You will need a hardwired Level 2 unit to push that much current.
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 8.8 hours |
| Range added per hour (Level 2) | about 25 miles |
| Full charge on a 120 V outlet | about 67 hours |
| Range added per hour (120 V) | about 3.3 miles |
| EPA rated range | 222 miles |
| Energy for a full charge | about 96.4 kWh at the wall |
Why 48 amps and not more
The Audi e-tron accepts up to 48 amps of alternating current through its J1772 port. Buying a larger 50-amp hardwired unit will not make the car charge any faster because the onboard hardware caps the draw at 48 amps. Pumping 48 amps into the 96.4 kWh battery pack fills it from empty in 8.8 hours. The EPA test pegs the session at 10.0 hours because federal testing protocols include efficiency losses and occasional power throttling.
What the install involves
You need a 60-amp breaker and heavy gauge copper wire pulled to the garage wall. A 48-amp continuous load requires a hardwired connection because no standard household receptacle is rated to handle that much sustained heat. Bring in a licensed electrician to check your main panel for spare capacity and land the new circuit. The professional will mount the unit directly to the wall studs and torque every lug to code.

Common questions
- Can I plug this car into a standard wall outlet?
- Yes, using Level 1 charging, but it crawls at 3.3 miles of range per hour. A full recharge from empty takes 67 hours on household current. You will want a Level 2 setup for daily convenience.
- 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. The e-tron follows this standard natively without needing dongles for home use.
- Why does the EPA charge time differ from the max rate?
- The EPA-rated charge time of 10.0 hours accounts for standard test cycles and thermal management overhead. Real-world charging at the maximum 48-amp rate finishes the job in 8.8 hours.
- Can I use Tesla destination chargers with my Audi?
- Yes, by adding a Tesla to J1772 adapter rated for at least 80 amps. This unlocks public destination chargers and older wall connectors while parked away from home.
