What EV Charger Do You Need for a 2026 Audi Q4 45 e-tron?
Forty-eight amps is the magic number for your Audi. This current level fills the 84.7 kWh battery pack in 7.7 hours. You will get 37 miles of range for every hour plugged into a Level 2 unit.
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 7.7 hours |
| Range added per hour (Level 2) | about 37 miles |
| Full charge on a 120 V outlet | about 59 hours |
| Range added per hour (120 V) | about 4.9 miles |
| EPA rated range | 288 miles |
| Energy for a full charge | about 84.7 kWh at the wall |
Why 48 amps and not more
Your car accepts a maximum onboard charging rate of 11.0 kW, which translates directly to 48 amps of draw. Buying a larger charger does not speed up the process because the vehicle limits the current it pulls. Pushing more amperage through a bigger EVSE is useless here. A 48 amp unit matches the onboard charger capability, keeping energy transfer efficient without wasting money on overhead the vehicle cannot digest.
What the install involves
A 48 amp charger draws a heavy load and must be hardwired directly to the circuit rather than plugged into a standard wall receptacle. Have a licensed electrician run a 60 amp breaker with heavy gauge wire to handle the continuous demand safely. The electrician needs to verify your electrical panel has sufficient spare capacity for the new 60 amp circuit before starting work. Hardwiring eliminates the failure points of high amperage plug connections.
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
- How long does a full charge take at home?
- A full charge takes 7.7 hours when using a Level 2 charger at the maximum 48 amp rate. Plugging into a standard Level 1 household outlet stretches that time to 59 hours.
- Can I use a normal wall outlet for Level 2 charging?
- No. A 48 amp EVSE must be hardwired because household receptacles cannot handle that much continuous current safely.
- What plug connector does the car use?
- The vehicle uses a J1772 connector. This model year falls in the industry transition period, so check your specific port before purchasing equipment.
- What is the EPA rated charge time?
- The EPA rating lists a charge time of 12.0 hours yielding 24 miles of range per hour. This standard test does not always run at the peak AC rate of the car.
Other vehicles
Charging times derived from EPA data for the 2026 Audi Q4 45 e-tron. Electrical requirements follow NEC 625.41, which sizes a circuit at 125% of a continuous load. Always have a licensed electrician verify your panel.
