What EV Charger Do You Need for a 2023 Audi e-tron S?
You need a 48 amp Level 2 home charging setup to fill your 2023 Audi e-tron S overnight. The car limits AC intake to 11.0 kilowatts, which means anything larger is wasted capacity. A standard plug will not work at this draw.
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 8.7 hours |
| Range added per hour (Level 2) | about 24 miles |
| Full charge on a 120 V outlet | about 66 hours |
| Range added per hour (120 V) | about 3.1 miles |
| EPA rated range | 208 miles |
| Energy for a full charge | about 95.5 kWh at the wall |
Why 48 amps and not more
Matching the vehicle max draws 48 amps through a recommended 48 amp EVSE. Plugging into a higher amperage supply will not speed up the 8.7 hour full charge time because the onboard charger cannot accept more than 11.0 kilowatts. Buying a 50 amp unit like the ChargePoint Home Flex allows you to dial down the amperage if your breaker panel has limited headroom. Sticking to 48 amps replenishes 24 miles of range every single hour. The EPA cycle estimates a slower 21 miles per hour because those official tests do not always run at the maximum AC rate of the vehicle.
What the install involves
A 48 amp continuous load demands a dedicated 60 amp breaker to stay within safety codes. You must hardwire the unit directly to the electrical supply because no household receptacle is rated for 48 amps. Call a licensed electrician to pull heavy gauge copper wire and land it on the new breaker in your panel. They will also verify that your main electrical service has spare capacity for the 60 amp draw.
Chargers that match this car
Energy monitoring built in. Hardwire it for the full 48 A.
Compact unit, good for tight garages.
Adjustable from 16 A to 50 A in the app, which helps if your panel is tight.

Common questions
- Can I use a regular wall outlet for Level 2 charging?
- No. A standard 120 volt household outlet delivers Level 1 charging, which only adds 3.1 miles of range per hour and takes 66 hours to fill the battery from empty.
- Why does the EPA charge time differ from the max rate?
- The EPA test cycle does not always run at the peak AC rate of the vehicle. That accounts for the difference between the 8.7 hour maximum rate and the 10.0 hour EPA estimate.
- What plug type does the car use?
- Your car uses a J1772 connector for all AC Level 2 charging. Every non Tesla EV sold in North America through 2024 uses this standard.
- Can I charge at a Tesla destination location?
- Yes, if you use an adapter like the Lectron Tesla to J1772 unit. It lets your J1772 car hook up to Tesla destination chargers and wall connectors.
Other vehicles
Charging times derived from EPA data for the 2023 Audi e-tron S (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.
