BMW i7 charging time by charger type
| Charger | 10% → 80% | 0% → 100% | Miles/hour |
|---|---|---|---|
| Level 1 — standard outlet (120 V, 12 A) | 63 h 45 min | 91 h 4 min | ~3 mi/h |

| DC fast charging (up to 195 kW)manufacturer estimate; power tapers past 80% | ~34 min | not recommended | — |
AC times include charging losses (~10% on Level 2, ~20% on Level 1). Cold weather, preconditioning, and the battery's state can stretch these figures. Charging past 80% is slow on DC and gentler on the battery when done on AC at home.
