What EV Charger Do You Need for a 2025 BMW i4 M50 Gran Coupe?
Forty-eight amps is what your car needs for maximum AC charging speed. You want a Level 2 unit capable of pushing this exact current. The onboard charger limits power delivery at 11.0 kilowatts, matching the 48 amp requirement. Plug in empty and expect a full battery in 8.7 hours.
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 31 miles |
| Full charge on a 120 V outlet | about 67 hours |
| Range added per hour (120 V) | about 4.0 miles |
| EPA rated range | 267 miles |
| Energy for a full charge | about 95.8 kWh at the wall |
Why 48 amps and not more
Your vehicle's onboard charger maxes out at 48 amps. Buying a 60 amp or 80 amp charger provides zero speed benefit because the car cannot draw past its 11.0 kilowatt limit. Dropping down to a 32 amp or 40 amp circuit slows down your daily turnover time. Stick to the 48 amp rating for the fastest home refill. Going higher wastes money on equipment the car ignores.
What the install involves
You need a dedicated 60 amp breaker paired with heavy gauge wiring. Hardwiring is mandatory because no standard wall receptacle safely handles 48 continuous amps. Call a licensed electrician to run the circuit and mount the unit directly to the wall. Do not attempt DIY installation unless you have professional electrical experience.

Common questions
- Can I use a regular wall outlet?
- No. Level 1 charging on a standard 120 volt household outlet yields only 4.0 miles of range per hour. A full charge takes 67 hours.
- What plug type does the car use?
- The vehicle uses a J1772 connector. Many 2025 models ship with a NACS port and include a J1772 adapter.
- Why does the EPA charge time differ?
- The EPA test cycle takes 10.0 hours at 27 miles of range per hour. Real world maximum output reaches 31 miles per hour over 8.7 hours.
- Will a 50 amp charger work?
- Yes, units like the ChargePoint Home Flex support adjustable amperages up to 50 amps. Set it to 48 amps to match your car's limit.
Other vehicles
Charging times derived from EPA data for the 2025 BMW i4 M50 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.
