What EV Charger Do You Need for a 2025 Audi SQ8 e-tron?
Many buyers make the mistake of purchasing a massive 80-amp home charger, which wastes money because your Audi SQ8 e-tron caps out at 48 amps anyway. You need a 48-amp Level 2 setup to match the vehicle's onboard charger. This hardware delivers 23 miles of range per hour and refills the 116.5 kWh battery in 10.6 hours. Do not pay for capacity your car cannot accept.
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
The 2025 Audi SQ8 e-tron features an onboard charger rated for 11.0 kW, which translates to a maximum draw of 48 amps on a Level 2 circuit. Plugging into a higher amperage unit yields zero benefit because the car limits the current internally. Anything smaller than 48 amps slows down your daily turnaround time at home. The EPA test protocol lists a 16.0-hour charge time at 15 miles of range per hour because federal testing accounts for grid losses and charging efficiency curves, not raw output. Matching the 48-amp threshold hits the exact limit of what the vehicle's hardware can process.
What the install involves
Supplying 48 amps of continuous current requires a dedicated 60-amp breaker and heavy-gauge copper wiring run directly from your main electrical panel. A 48-amp Level 2 charger must be hardwired because no standard household receptacle is rated to handle that much thermal load over ten hours. Call a licensed electrician to pull the wire, land the leads on the 60-amp breaker, and verify your main panel has spare capacity for the load. Ask the electrician to inspect the run length so voltage drop stays within safe limits.

Common questions
- Can I plug this car into a standard wall outlet?
- You can plug into a standard household outlet using Level 1 charging, but it takes 81 hours to fill the battery from empty. That mode only yields 3.0 miles of range per hour. You need a dedicated Level 2 circuit for normal daily driving.
- What connector does the car use?
- The vehicle uses a J1772 connector for home charging. This model year falls in the industry transition to NACS, meaning some vehicles ship with a NACS port and include a J1772 adapter. Confirm your exact port configuration before buying hardware.
- Do I need an electrician for the install?
- Yes. Hardwiring a 48-amp charger to a 60-amp breaker involves high voltage and strict local building codes. An electrician must run the correct wire gauge and mount the unit safely.
- What is the total battery capacity?
- The battery holds 116.5 kWh of energy and achieves an efficiency of 48.1 kWh per 100 miles. Total EPA range reaches 242 miles on a full charge.
