What EV Charger Do You Need for a 2024 BMW i4 M50 Gran Coupe?
A full charge takes 8.6 hours on a proper Level 2 setup. That timeline easily covers an overnight refill from empty. You need a 48 amp EVSE to hit that peak speed. Level 1 charging takes 66 hours and serves little practical purpose.
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 8.6 hours |
| Range added per hour (Level 2) | about 31 miles |
| Full charge on a 120 V outlet | about 66 hours |
| Range added per hour (120 V) | about 4.1 miles |
| EPA rated range | 269 miles |
| Energy for a full charge | about 95.1 kWh at the wall |
Why 48 amps and not more
Your car accepts up to 48 amps at 11.0 kW. Buying a larger 50 amp charger like the ChargePoint unit wastes money because the onboard charger caps power intake. Feeding the car 48 amps yields 31 miles of range per hour. Dropping to a smaller circuit slows down the refill speed without any gain.
What the install involves
Hooking up a 48 amp EVSE demands a dedicated 60 amp breaker. Local electrical codes prohibit using a standard wall outlet for this load. You must hardwire the unit directly to the supply lines. Hire a licensed electrician unless you have professional training in residential electrical work.

Common questions
- What plug does the car use?
- Your car features a J1772 connector. Every non-Tesla EV sold in North America through 2024 uses this standard for Level 2 AC charging.
- Can I use a standard 120 volt outlet?
- Plugging into a regular household outlet delivers 4.1 miles of range per hour. A full battery takes 66 hours this way.
- What do the EPA test numbers mean?
- The EPA lists an 8.0 hour charge time yielding 34 miles per hour. That test measures average charging efficiency over a standard cycle rather than peak output.
- Which charger should I buy?
- Both the Emporia 48A and Lectron V-Box 48A supply the maximum current your car accepts. Hardwire either one to get 48 amps of continuous output.
Other vehicles
Charging times derived from EPA data for the 2024 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.
