BMW iX3 charging speed
The BMW iX3 does not have one charging speed — it depends on the variant. It is 22 kW three-phase on the 50 xDrive, and 11 kW three-phase on the 40 (from Q4 2026). Which one you own changes what you should install at home.
It depends which BMW iX3 you have
This is the trap. Two cars wearing the same badge can need completely different chargers, and the dealer is unlikely to mention it. Find your variant below before you spend anything.
The 50 xDrive — 22 kW three-phase
This car steps up from 7.4 kW single-phase to 22 kW on three-phase — a gain of 15 kW. If you already have a three-phase supply, install a three-phase charger. This car is one of the few sold in Australia that can genuinely use it.
The 40 (from Q4 2026) — 11 kW three-phase
This car draws 7.4 kW single-phase and 11 kW on three-phase — a gain of about 3.6 kW. Real, but modest. If you already have three-phase, use it. If you don't, the upgrade is hard to justify on charging speed alone.
The short answer
On the standard Australian home charger — 32 A single-phase — The 50 xDrive draws 7.4 kW, adding roughly 36 km of range per hour. Over an eight-hour overnight window that is about 286 km — far more than most Australians drive in a day.
On the standard Australian home charger — 32 A single-phase — The 40 (from Q4 2026) draws 7.4 kW, adding roughly 37 km of range per hour. Over an eight-hour overnight window that is about 294 km — far more than most Australians drive in a day.
What every charger actually delivers
Every figure below is computed live from this car's onboard charger rating, not copied from a brochure. "Wasted" is capacity you would pay for and never use.
The 50 xDrive — 22 kW three-phase
| Charger | Supply | This car draws | Range per hour | 20–80% | Wasted |
|---|---|---|---|---|---|
| 10 A power point | Single-phase | 1.8 kW | 8 km | 1 day 17 h | — |
| 15 A power point | Single-phase | 2.8 kW | 13 km | 1 day 2 h | — |
| 32 A single-phase charger | Single-phase | 7.4 kW | 36 km | 9 h 51 min | — |
| 16 A three-phase charger | Three-phase | 11 kW | 54 km | 6 h 32 min | — |
| 32 A three-phase charger | Three-phase | 22 kW | 107 km | 3 h 18 min | — |
Assumes a battery of 108.7 kWh and real-world consumption of 185 Wh/km (segment estimate). Charging losses of about 10% are included. Change the assumptions in the calculator →
The 40 (from Q4 2026) — 11 kW three-phase
| Charger | Supply | This car draws | Range per hour | 20–80% | Wasted |
|---|---|---|---|---|---|
| 10 A power point | Single-phase | 1.8 kW | 9 km | 1 day 7 h | — |
| 15 A power point | Single-phase | 2.8 kW | 14 km | 19 h 57 min | — |
| 32 A single-phase charger | Single-phase | 7.4 kW | 37 km | 7 h 29 min | — |
| 16 A three-phase charger | Three-phase | 11 kW | 55 km | 5 h | — |
| 32 A three-phase charger | Three-phase | 11 kW | 55 km | 5 h | 11 |
Assumes a battery of 82.6 kWh and real-world consumption of 180 Wh/km (segment estimate). Charging losses of about 10% are included. Change the assumptions in the calculator →
Charging by variant
| Variant | Onboard AC charger | Type | Battery (kWh) | DC max (kW) |
|---|---|---|---|---|
| 50 xDrive | 22 kW | Three-phase | 108.7 | 400 |
| 40 (from Q4 2026) | 11 kW | Three-phase | 82.6 | 300 |
Notes
- One of the very few cars sold in Australia with a genuine 22 kW onboard charger — three-phase, standard in Australia. If you own one, a 22 kW home charger is actually worth it.
- Base iX3: 11 kW three-phase standard, with a 22 kW onboard charger available as an option. Arriving in Australia around Q4 2026.
