What EV Charger Do You Need for a 2024 Audi Q4 55 e-tron?
Many buyers make the mistake of purchasing an 80-amp charging station, wasting hundreds of dollars on capacity your car cannot accept. Your Audi Q4 55 e-tron draws up to 48 amps of current for Level 2 charging. You need a 48-amp Level 2 setup to hit the maximum onboard charging rate of 11.0 kilowatts. Anything larger is money down the drain.
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 7.9 hours |
| Range added per hour (Level 2) | about 33 miles |
| Full charge on a 120 V outlet | about 60 hours |
| Range added per hour (120 V) | about 4.3 miles |
| EPA rated range | 258 miles |
| Energy for a full charge | about 87.0 kWh at the wall |
Why 48 amps and not more
The vehicle has an 87.0 kilowatt-hour battery pack. Feeding it 48 amps delivers 33 miles of range every hour, filling an empty pack in 7.9 hours. If you hook this car up to a larger 60-amp or 80-amp supply, the onboard charger limits the intake to 48 amps anyway. Extra amperage sits idle. Stick to the 48-amp ceiling. It matches the hardware on board.
What the install involves
You must hardwire your 48-amp EVSE because no household receptacle is rated for that load. Have a licensed electrician run a dedicated circuit with a 60-amp breaker to your garage wall. The electrician will pull heavy copper wire, land it directly on the breaker, and check your service panel for spare electrical capacity. Do not attempt DIY wiring for high-amperage continuous loads.

Common questions
- Can I plug this car into a standard wall outlet?
- You can plug into a standard household outlet using Level 1 equipment, but it adds 4.3 miles of range per hour. A full charge from empty takes 60 hours. Treat Level 1 as an absolute emergency backup.
- What plug does the car use?
- Your car uses a J1772 connector for all AC Level 2 charging sessions. Every non-Tesla EV sold in North America through 2024 uses this standard plug. You do not need a special adapter for standard public or home chargers.
- Why does the EPA charge time show 12 hours?
- The EPA test does not always run at the car's peak AC rate, which accounts for the longer duration in their official estimates. Under ideal home conditions matching your 48-amp setup, a full charge takes 7.9 hours and yields 33 miles per hour.
- Can I use Tesla destination chargers?
- Yes, if you buy a proper adapter like the Lectron Tesla to J1772 charging adapter. It lets your J1772 car pull power from Tesla Destination Chargers and Wall Connectors.
