What EV Charger Do You Need for a 2025 Audi SQ8 Sportback e-tron?
A full charge takes 10.6 hours on Level 2 equipment. That window easily fits an overnight top-up. Plug in after dinner, wake up to a full battery.
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 23 miles |
| Full charge on a 120 V outlet | about 81 hours |
| Range added per hour (120 V) | about 3.0 miles |
| EPA rated range | 242 miles |
| Energy for a full charge | about 116.5 kWh at the wall |
Why 48 amps and not more
Your car accepts up to 48 amps of alternating current. Match that figure with a 48 amp EVSE to pull 11.0 kilowatts from the wall. Going to a larger 50 amp or 80 amp unit wastes money because the onboard charger caps your intake anyway. Feeding it fewer amps slows down your replenishment rate for no gain. Stick to the 48 amp rating for maximum speed.
What the install involves
You need a dedicated 60 amp breaker installed in your main electrical panel. Run heavy gauge copper wire from that breaker directly to the garage wall. Hardwire the unit permanently because no household receptacle safely handles 48 continuous amps. Call a licensed electrician to pull the circuit, land the wires on the breaker, and verify your service panel has spare capacity for the heavy load.
Chargers that match this car

Common questions
- Can I use a normal wall outlet?
- Level 1 charging on a standard household outlet takes 81 hours for a full tank. It adds 3.0 miles of range per hour. You will want a dedicated Level 2 setup instead.
- What connector does this car use?
- It uses a J1772 connector. Many 2025 plus vehicles ship with a NACS port but include a J1772 adapter. Confirm your car port before buying.
- How many miles of range do I get per hour?
- At maximum Level 2 speed, you add 23 miles of range every hour. The EPA test rates the car at 15 miles of range per hour because standard laboratory tests do not always run at the vehicle peak AC rate.
- What is the battery capacity?
- The battery pack holds 116.5 kWh of total energy. That energy moves the 242 mile range vehicle at an efficiency of 48.1 kWh per 100 miles.
Other vehicles
Charging times derived from EPA data for the 2025 Audi SQ8 Sportback 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.
