What EV Charger Do You Need for a 2024 BMW i4 xDrive40 Gran Coupe?
Residential EV chargers can often push more power than your car's onboard system can draw. This BMW limits incoming AC power to 48 amps. You need a 48-amp Level 2 setup to hit its peak charge rate. Anything larger wastes money on hardware the car ignores.
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 36 miles |
| Full charge on a 120 V outlet | about 66 hours |
| Range added per hour (120 V) | about 4.6 miles |
| EPA rated range | 307 miles |
| Energy for a full charge | about 95.1 kWh at the wall |
Why 48 amps and not more
The onboard charger maxes out at 11.0 kW. Feeding it a 48-amp supply fills the 95.1 kWh battery in 8.6 hours. The EPA test logs a slightly faster 8.0-hour window due to test parameters, but real-world overnight top-ups match the 8.6-hour figure. Upgrading to a 50-amp or 60-amp circuit changes nothing because the car caps draw at 48 amps. Stick to the recommended 48-amp EVSE.
What the install involves
A 48-amp continuous load requires a 60-amp circuit breaker. You cannot use a standard wall outlet because no household receptacle handles that continuous draw safely. Hardwiring is mandatory for this amperage level. Call an electrician to run proper copper wiring from your main panel to the charger location.
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 plug this car into a standard wall outlet?
- Level 1 charging from a standard household outlet takes 66 hours for a full charge. It adds only 4.6 miles of range per hour. You will want a Level 2 setup for daily driving.
- What connector does the car use?
- The vehicle uses a J1772 connector. Every non-Tesla EV sold in North America through 2024 uses this standard for AC Level 2 charging.
- How much range do I get per hour on Level 2?
- You regain 36 miles of range for every hour plugged into a 48-amp supply. The EPA test rates the speed slightly higher at 38 miles per hour.
- Do I need to hire an electrician?
- Yes. Installing a 60-amp breaker and hardwiring a 48-amp EVSE involves heavy electrical work. Do not attempt DIY installation on high-amperage circuits.
Other vehicles
Charging times derived from EPA data for the 2024 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.
