BYD Atto 3 charging speed
The BYD Atto 3 has a 7.0 kW single-phase onboard charger. That number — not the charger on your wall — is what decides how fast it charges at home.
Three-phase will do nothing for this car
The BYD Atto 3 has a single-phase onboard charger. On a 22 kW three-phase charger it draws 7.0 kW — exactly what a cheaper 32 A single-phase unit already gives it. Upgrading your home to three-phase, which typically costs $2,500–$6,000, would not make this car charge one minute faster. Buy a 32 A single-phase charger and spend the difference on something else.
The short answer
On the standard Australian home charger — 32 A single-phase — The BYD Atto 3 draws 7.0 kW, adding roughly 37 km of range per hour. Over an eight-hour overnight window that is about 295 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 | 9 km | 19 h 9 min | — |
| 15 A power point | Single-phase | 2.8 kW | 15 km | 12 h 3 min | — |
| 32 A single-phase charger | Single-phase | 7.0 kW | 37 km | 4 h 45 min | — |
| 16 A three-phase charger | Three-phase | 3.7 kW | 19 km | 9 h 3 min | 7.4 |
| 32 A three-phase charger | Three-phase | 7.0 kW | 37 km | 4 h 45 min | 15 |
Assumes a battery of 49.92 kWh and real-world consumption of 171 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 →
