What EV Charger Do You Need for a 2023 Audi Q4 e-tron?
Your garage circuit can push more power than many residential panels tolerate, but your car dictates the actual intake. The Audi Q4 e-tron accepts up to 48 amps of Level 2 charging through its onboard hardware. You need a 48 amp EVSE to hit the maximum speed. Plug it in at night and walk away.
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 34 miles |
| Full charge on a 120 V outlet | about 60 hours |
| Range added per hour (120 V) | about 4.4 miles |
| EPA rated range | 265 miles |
| Energy for a full charge | about 86.6 kWh at the wall |
Why 48 amps and not more
The vehicle handles a maximum of 11.0 kW, which translates directly to 48 amps on a 240 volt line. Buying a larger 60 amp or 80 amp charger yields zero speed gains because the onboard charger limits the flow. Feeding it 48 amps gets you a full battery in 7.9 hours, adding 34 miles of range every hour. The EPA test reports a slower 9.0 hours and 29 miles per hour because federal testing cycles include efficiency losses and specific temperature constraints. Sticking to 48 amps matches the factory limits without wasting money on overhead the car rejects.
What the install involves
A 48 amp continuous load requires a dedicated 60 amp breaker paired with heavy gauge copper wire. You must hardwire the unit directly to the electrical panel because no household receptacle is rated for a continuous 48 amp draw. Have a licensed electrician pull the wire, land it on the breaker, and verify your main panel has spare capacity for the load. Do not attempt a DIY install on a circuit this heavy.
Chargers that match this car
Energy monitoring built in. Hardwire it for the full 48 A.
Compact unit, good for tight garages.
Adjustable from 16 A to 50 A in the app, which helps if your panel is tight.

Common questions
- Can I use a standard wall outlet?
- No. Standard household outlets provide Level 1 charging at 120 volts, which takes 60 hours to fill the 86.6 kWh battery and adds only 4.4 miles of range per hour. You need a hardwired Level 2 setup.
- What connector does the car use?
- This vehicle uses a J1772 connector for all AC Level 2 charging. Every non-Tesla EV sold in North America through 2024 relies on this standard plug.
- Will a 50 amp or 80 amp charger charge the car faster?
- No. The car maxes out at 48 amps, so any extra capacity on the charger side goes unused. Your charge time stays identical.
- What is the efficiency of this vehicle?
- The EPA rates the car at 32.7 kWh per 100 miles, yielding an efficiency of 103 MPGe. You get 265 miles of total range on a full charge.
Other vehicles
