What EV Charger Do You Need for a 2025 BMW i4 xDrive40 Gran Coupe?
Your garage circuit might deliver plenty of power, but the car dictates what flows into the battery. A 48 amp Level 2 charger feeds this vehicle at its maximum onboard limit of 11.0 kW. You need a 60 amp breaker and a hardwired connection to hit that peak speed. Plan on hiring an electrician unless you already have heavy-gauge wiring in place.
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 33 miles |
| Full charge on a 120 V outlet | about 67 hours |
| Range added per hour (120 V) | about 4.3 miles |
| EPA rated range | 287 miles |
| Energy for a full charge | about 95.9 kWh at the wall |
Why 48 amps and not more
The car draws 48 amps max, so buying a larger 50 amp or 80 amp home charger gets you nothing extra. Extra amperage sits unused because the onboard charger limits power intake. Charging takes 8.7 hours from empty to full at this 48 amp rate. Pushing more current into the port is physically impossible for this model. Stick to the 48 amp rating and skip paying for capacity the car cannot ingest.
What the install involves
Code requires a 60 amp breaker for a 48 amp continuous load. Hardwiring is mandatory here because no standard household receptacle handles 48 amps safely. Hire an electrician to run THHN copper wire through conduit straight to the unit. The electrician must also verify your main electrical panel has enough spare capacity for the 60 amp draw.

Common questions
- Can I plug this car into a standard wall outlet?
- Yes, but Level 1 charging takes 67 hours to reach full capacity. You get about 4.3 miles of range per hour of charge time.
- Why does the EPA charge time differ from the max rate?
- The EPA-rated Level 2 charge time takes 10.0 hours instead of 8.7 hours. Government test procedures do not always run at the car's peak AC rate.
- What plug type does the car use?
- The car uses a J1772 connector. This model year falls in the industry's NACS transition, so confirm your physical port before buying.
- How many miles of range do I get per hour on Level 2?
- You add 33 miles of range for every hour plugged into a 48 amp Level 2 charger. The EPA test method yields 29 miles per hour.
Other vehicles
Charging times derived from EPA data for the 2025 BMW i4 xDrive40 Gran Coupe (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.
