What EV Charger Do You Need for a 2026 BMW i4 eDrive35 Gran Coupe?
You need a 48 amp Level 2 home charger to fill the battery of your 2026 BMW i4 eDrive35 Gran Coupe overnight. The car handles up to 11.0 kW of AC power through its onboard charger. A smaller unit slows down your daily turnaround time. Anything larger is a waste of money because the vehicle cannot draw more current.
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 7.0 hours |
| Range added per hour (Level 2) | about 36 miles |
| Full charge on a 120 V outlet | about 54 hours |
| Range added per hour (120 V) | about 4.7 miles |
| EPA rated range | 251 miles |
| Energy for a full charge | about 77.4 kWh at the wall |
Why 48 amps and not more
Matching the 48 amp onboard limit gets you 36 miles of range per hour. A full recharge takes 7.0 hours from empty. If you hook this car up to a 60 amp supply, it takes the maximum possible AC rate. Plugs rated for less amperage force the car to throttle down its intake. You gain nothing by buying a 50 amp or 80 amp charger because the internal hardware caps out right at 48 amps.
What the install involves
A 48 amp load requires a dedicated 60 amp breaker wired straight to the unit. No household receptacle handles this continuous draw safely. You must hardwire the connection. Call a licensed electrician to run heavy gauge copper wire from your main electrical panel to the garage wall. Do not attempt DIY installation on a circuit this heavy.

Common questions
- What plug does the car use?
- It uses a J1772 connector. Many 2025+ vehicles ship with a NACS port but include a J1772 adapter, so a J1772 home charger still works. Confirm your car's port before buying.
- How long does a standard wall outlet take?
- A standard Level 1 setup delivers 4.7 miles of range per hour. Filling the 77.4 kWh battery this way takes 54 hours. Use Level 2 instead.
- Can I use an extension cord with my Level 2 charger?
- Never use an extension cord for high amperage EV charging. High current draws generate extreme heat across long runs. Hardwire the unit directly to eliminate failure points.
- What is the total battery capacity?
- The pack holds 77.4 kWh of energy. That provides an EPA rated range of 251 miles. Efficiency sits at 30.8 kWh per 100 miles.
