What EV Charger Do You Need for a 2022 Audi Q4 e-tron?
Your home wall circuit can pump plenty of juice, but the Audi Q4 e-tron stops accepting power at 48 amps. Buying a massive 80 amp charger changes nothing for your daily refill speed. Match your hardware to the onboard charger limit.
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 7.8 hours |
| Range added per hour (Level 2) | about 31 miles |
| Full charge on a 120 V outlet | about 60 hours |
| Range added per hour (120 V) | about 4.0 miles |
| EPA rated range | 241 miles |
| Energy for a full charge | about 85.9 kWh at the wall |
Why 48 amps and not more
The 2022 Audi Q4 e-tron has a maximum onboard AC rate of 11.0 kW, which translates directly to 48 amps. Feeding it anything above 48 amps is a waste of money because the car will not draw it. At this peak rate, you add 31 miles of range every hour. A full battery takes 7.8 hours from empty. The EPA test protocol measures a slower 9.0 hours because that specific testing cycle does not maintain the car's peak AC rate the entire time.
What the install involves
You need a 60 amp breaker to run a 48 amp charger safely. A 48 amp EVSE must be hardwired because no household receptacle is rated for that continuous draw. Call a licensed electrician to pull a heavy copper circuit and land it on the new breaker. Ask them to verify your main panel has spare capacity before they start.

Common questions
- 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.
- Can I use a standard wall outlet?
- Yes, but Level 1 charging on a standard household outlet takes 60 hours for a full tank and only adds 4.0 miles of range per hour. You will want a Level 2 setup for daily convenience.
- Will a 50 amp charger charge my car faster?
- No, because the car caps its AC intake at 48 amps. A larger unit like the ChargePoint Home Flex can be set to 48 amps in the app to match your car.
- Can I charge at Tesla stations?
- You can use Tesla Destination Chargers and Wall Connectors if you buy a Tesla to J1772 charging adapter rated for 80 amps.
