Kia EV9 charging speed
The Kia EV9 has a 11 kW three-phase onboard charger. That number — not the charger on your wall — is what decides how fast it charges at home.
Three-phase helps a little
This car draws 7.4 kW single-phase and 11 kW on three-phase — a gain of about 3.1 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 Kia EV9 draws 7.4 kW, adding roughly 33 km of range per hour. Over an eight-hour overnight window that is about 266 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.
| Charger | Supply | This car draws | Range per hour | 20–80% | Wasted |
|---|---|---|---|---|---|
| 10 A power point | Single-phase | 1.8 kW | 8 km | 1 day 3 h | — |
| 15 A power point | Single-phase | 2.8 kW | 12 km | 17 h 35 min | — |
| 32 A single-phase charger | Single-phase | 7.4 kW | 33 km | 6 h 36 min | — |
| 16 A three-phase charger | Three-phase | 11 kW | 47 km | 4 h 37 min | — |
| 32 A three-phase charger | Three-phase | 11 kW | 47 km | 4 h 37 min | 12 |
Assumes a battery of 72.8 kWh and real-world consumption of 199 Wh/km — measured on Australian roads by the AAA Real-World Testing Program. 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) |
