What EV Charger Do You Need for a 2022 Audi RS e-tron GT?
Forty-eight amps is the magic number. That is the peak AC rate the 2022 Audi RS e-tron GT can handle on a Level 2 setup. You need a 48 amp charger to fill the 97.1 kWh battery from empty in 8.8 hours. Plug it in overnight and wake up to 232 miles of range.
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 26 miles |
| Full charge on a 120 V outlet | about 67 hours |
| Range added per hour (120 V) | about 3.4 miles |
| EPA rated range | 232 miles |
| Energy for a full charge | about 97.1 kWh at the wall |
Why 48 amps and not more
The car has an 11.0 kW onboard charger. Buying a bigger 60 amp or 80 amp unit makes zero difference because the vehicle's onboard hardware limits the intake. Feeding it 48 amps yields 26 miles of range per hour. The EPA test pegs the rate at 23 miles of range per hour over 10.0 hours because standard testing protocols factor in charging losses and variable grid conditions. Anything smaller than 48 amps slows down your turnaround time.
What the install involves
A 48 amp continuous load demands a 60 amp breaker. Run heavy gauge copper wire from the panel to the garage wall. No household receptacle is rated for 48 amps, so you must hardwire the charging unit directly. Call a licensed electrician to pull the wire, land it on the new breaker, and verify your main panel has spare electrical capacity.

Common questions
- Can I use a standard wall outlet?
- No. Standard wall outlets provide Level 1 charging at 3.4 miles of range per hour, which takes 67 hours to fill the pack.
- What connector does this car use?
- It uses a J1772 connector. Every non-Tesla EV sold in North America through 2024 uses the J1772 connector for AC Level 2 charging.
- Will a 50 amp charger charge it faster?
- No. The car caps AC intake at 48 amps, so extra capacity at the charger goes unused.
- Can I charge at Tesla Destination Chargers?
- Yes, if you buy a Tesla to J1772 adapter. That allows a J1772 car to use Tesla Destination Chargers and Wall Connectors.
