What EV Charger Do You Need for a 2024 Audi Q4 40 e-tron?
A full charge takes 7.9 hours at maximum Level 2 speed. That means overnight recovery fits easily into a standard sleeping schedule. Your Audi Q4 40 e-tron draws up to 48 amps.
The numbers
| Maximum AC charging rate | 11.0 kW (48 A) |
|---|---|

| 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
Matching the vehicle onboard charger requires a 48 amp supply. Pushing more current past this limit accomplishes nothing because the car caps intake at 11.0 kilowatts. A smaller unit works fine, but it adds hours to your wait time. Stick with the specified 48 amp capacity to capture 34 miles of range every single hour. Anything larger wastes money on hardware the vehicle cannot use.
What the install involves
A 60 amp breaker feeds the circuit. Hardwiring is mandatory for this load level because no household receptacle handles 48 amps safely. Have a qualified electrician pull the wire and land it directly on the breaker. Ask them to verify your main panel has spare capacity before starting the job.

Common questions
- How long does a standard wall outlet take?
- Plugging into Level 1 requires 60 hours for a full tank. You gain only 4.4 miles of range per hour.
- Can I use a Tesla charger with this vehicle?
- Yes, but you need a Tesla to J1772 adapter rated for at least 80 amps. The car itself uses a standard J1772 port for all AC charging.
- What is the difference between peak rate and EPA charge time?
- The EPA test takes 9.0 hours instead of 7.9 hours. Standard testing cycles do not always run at the maximum AC rate the vehicle can accept.
- What kind of hardware should I buy?
- Units like the Emporia Level 2 EV Charger 48A or the Wallbox Pulsar Plus 48A match your car's maximum draw. Both units output the full 48 amps required for fast overnight charging.
