What home charger does the BMW i5 need?
| Model years | Trims | Charger | Breaker |
|---|---|---|---|
| 2024-2027 | all trims | 48 A | 60 A |
Fit a 48 A charger for the BMW i5 and you're done. Every i5 from 2024 to 2027 accepts 11.0 kW, and that takes a 48 A unit on a 60 A circuit.
Why 48 amps and not more
BMW limits AC charging in the car, so an 80 A charger delivers the same 48 A as a smaller one. Go below 48 A and you lose speed. A 2027 i5 on a 40 A unit adds 28 to 32 miles of range per hour, compared with 33 to 38.
Charging time by model year
| Year | EPA range | Level 2, miles per hour | Level 2, empty to full | 120 V, miles per hour |
|---|---|---|---|---|
| 2027 | 262 to 328 mi | 33 to 38 | 8.6 to 8.7 h | 4.3 to 5 |
| 2026 | 259 to 310 mi | 32 to 36 | 8.6 to 8.7 h | 4.2 to 4.7 |
| 2025 | 239 to 295 mi | 29 to 34 | 8.6 to 8.7 h | 3.8 to 4.5 |
| 2024 | 240 to 295 mi | 30 to 34 | 8.6 h | 3.9 to 4.5 |
Level 2 figures assume a charger that supplies the car's full rate. Where a year shows a range, it spans that year's trims.
Year to year, the i5 changed very little at the plug. Charging from empty takes 8.6 to 8.7 hours in every model year, while the rate edged up from 30 to 34 miles of range per hour on 2024 cars to 33 to 38 on 2027 cars.
What the install involves
Where the unit goes matters more than people expect. Measure from the charger location to the i5's charge port with the car parked the way you normally park it, and leave slack. A 48 A charger is hardwired to its 60 A breaker, so moving it later means another visit from the electrician.
- 48 A charger: 60 A breaker, hardwired, because no household receptacle is rated for a 48 A charger.
- Charge port, 2024: J1772. Every non-Tesla EV sold in North America through 2024 uses the J1772 connector for AC Level 2 charging.
- Charge port, 2025-2027: J1772. From 2025 the industry is moving to the NACS port, and makers switch at different times. Some of these cars have a J1772 port and some have NACS with an adapter, so look at the port on your own car before choosing a charger's plug.
Chargers that fit the BMW i5
Smallest adequate unit first. Every amp above what the car accepts is capacity it never uses.
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
- Is a 40 A charger enough for a BMW i5?
- It works on a 50 A breaker with a NEMA 14-50 outlet. On a 2027 you'd see 28 to 32 miles of range per hour instead of 33 to 38.
- Will a bigger charger make a BMW i5 charge faster?
- No. The i5 caps AC charging at 11.0 kW, which a 48 A unit already supplies.
- How long does a BMW i5 take to charge overnight?
- About 8.6 to 8.7 hours from empty on a 48 A charger.
- Do I need a permit for a BMW i5 home charger?
- Usually. A new 240 V circuit typically requires a permit and an inspection, which the electrician arranges.
Other models
Range and efficiency come from EPA data for the BMW i5, covering 10 EPA listings across 4 model years. Onboard charger ratings are from manufacturer specifications. Breakers follow NEC 625.41, which sizes a continuous load at 125%. Have a licensed electrician check your panel before buying.
