What EV Charger Do You Need for a 2025 Audi Q4 45 e-tron?
Forty-eight amps is the magic number for the Audi Q4 45 e-tron. It fills the 84.7 kWh battery pack in 7.7 hours on Level 2 equipment. Plug it in overnight and wake up to 288 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 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
The onboard charger maxes out at 48 amps, drawing 11.0 kW. Buying a bigger 60-amp or 80-amp EVSE wastes money because the car cannot pull any faster. Your vehicle gains 37 miles of range every hour at this ceiling. Going down to a smaller 32-amp or 40-amp unit slows down your nightly refill time. Feed the car what it asks for and let it rest.
What the install involves
A 48-amp continuous load requires a 60-amp breaker and heavy copper wire. No standard wall outlet handles this current safely, so hardwiring is mandatory. Call a licensed electrician to pull the wire, land it on the new breaker, and check your panel for spare capacity. Do not try to backfeed an old dryer plug for this kind of draw.
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 regular 120-volt wall outlet?
- Yes, but Level 1 charging takes 59 hours to reach full from empty. You will only get 4.9 miles of range per hour of charging. Most drivers upgrade to Level 2 quickly.
- What connector does the car use?
- It uses a J1772 connector. Many 2025 plus models ship with a NACS port and include a J1772 adapter, so verify your physical port before ordering parts.
- Why does the EPA charge time say 12 hours?
- The EPA test cycle uses lower current limits and testing protocols that do not reflect the car's maximum 11.0 kW AC acceptance rate. Under normal daily conditions at 48 amps, you get the full charge in 7.7 hours.
- Will a 50-amp hardwired charger work?
- Units like the ChargePoint Home Flex can be set to different limits, but your Audi takes 48 amps peak. Match the circuit to the 60-amp requirement for the best results.
Other vehicles
Charging times derived from EPA data for the 2025 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.
