What EV Charger Do You Need for a 2025 Audi Q4 55 e-tron?
Forty-eight amps is the magic number for your vehicle. You need a 48 amp Level 2 setup to pull the maximum 11.0 kilowatts your onboard charger accepts. Anything smaller leaves speed on the table. Let us look at what it takes to wire that up.
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
Your battery wall holds 87.0 kWh, meaning you need a high output circuit to replenish the 258 miles of range overnight. Feeding 48 amps into the car delivers 33 miles of range per hour of charging. Plugging into a smaller 32 amp or 40 amp unit throttles your intake. The car ignores extra power if you hook up a 50 amp or 80 amp box anyway. Match the recommended 48 amp equipment to hit the 7.9 hour full charge time.
What the install involves
You must pull a heavy 6-gauge copper wire to handle the load without melting insulation. Land that wire on a dedicated 60-amp circuit breaker in your distribution panel. Do not look for a wall outlet for this job because a 48 amp EVSE must be hardwired. No household receptacle is rated for a continuous draw of this size. Bring in a licensed electrician to check if your main panel has spare capacity for the 60-amp breaker.

Common questions
- How long does a full charge take?
- A full charge takes 7.9 hours when using the maximum Level 2 rate of 48 amps. Standard Level 1 household charging stretches that same empty battery to 60 hours.
- Can I use a standard wall outlet?
- No wall outlet can handle 48 amps of continuous current safely. You must hardwire the unit directly to the electrical circuit.
- What plug connector does the car use?
- The vehicle relies on a J1772 connector for home charging. This model year falls in the industry transition, so confirm your specific port before buying hardware.
- Why does the EPA charge time differ?
- The EPA test cycle rates a full charge at 12.0 hours. That slower figure happens because the official test procedure does not always run at the car's peak AC rate.
Other vehicles
Charging times derived from EPA data for the 2025 Audi Q4 55 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.
