What EV Charger Do You Need for a 2024 Audi SQ8 e-tron?
Wiring a home charger for your Audi SQ8 e-tron requires a 60 amp breaker and direct hardwiring. No household receptacle handles the necessary current safely. You need a licensed electrician to pull the heavy wire and land it on the panel. The car takes 48 amps at peak performance.
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 10.6 hours |
| Range added per hour (Level 2) | about 24 miles |
| Full charge on a 120 V outlet | about 81 hours |
| Range added per hour (120 V) | about 3.1 miles |
| EPA rated range | 253 miles |
| Energy for a full charge | about 116.6 kWh at the wall |
Why 48 amps and not more
Your car accepts up to 48 amps of alternating current, meaning a 48 amp Level 2 setup refills the 116.6 kWh battery in 10.6 hours. Buying a larger charging unit provides no speed benefit because the onboard charger limits current intake. Plugging into a smaller circuit only throttles your charging speed. Feed the car its maximum intake rate to keep downtime minimal. The system delivers 24 miles of range per hour of charging.
What the install involves
Hardwiring is mandatory for this 48 amp load. A 60 amp breaker must protect the circuit to supply the necessary continuous current safely. Ask an electrician to check your main panel for spare capacity before buying hardware. Running thick copper wire straight from the breaker to a wall unit avoids thermal risks associated with high amperage outlets.

Common questions
- What connector does the SQ8 e-tron use?
- Your car uses the standard J1772 connector for all alternating current Level 2 charging. Every non-Tesla electric vehicle sold in North America through 2024 relies on this plug.
- Can I use a standard wall outlet?
- Standard household outlets deliver Level 1 power, which takes 81 hours to fill the battery from empty. You must install a dedicated high-voltage circuit to get practical home charging speeds.
- Why does the EPA charge time differ from the peak rate?
- The EPA test does not always run at the car's peak AC rate, which explains why official agency estimates show 16.0 hours for a full charge. Real world charging at the maximum 48 amp rate takes 10.6 hours.
- Can I charge at Tesla stations?
- You can use Tesla Destination Chargers and Wall Connectors if you purchase a separate Tesla to J1772 adapter. This lets your J1772 car hook up to those specific Tesla units.
Other vehicles
Charging times derived from EPA data for the 2024 Audi SQ8 e-tron (covering 2 EPA trim listings). Electrical requirements follow NEC 625.41, which sizes a circuit at 125% of a continuous load. Always have a licensed electrician verify your panel.
