Add to cartPower (kW) = volts × amps ÷ 1,000. A standard Australian power point at 230 V and 10 A delivers about 2.3 kW, which adds about 13 km of range per hour. A 15 A outlet delivers about 3.45 kW (19 km per hour) and a 7 kW wall charger about 7.4 kW. kWh is energy: a 60 kWh battery holds what a 2.3 kW charger delivers in about 26 hours, before losses.
- kW is speed, like litres per minute at a bowser.
- kWh is quantity, like litres in the tank.
- Australian homes run at about 230 V, so amps × 0.23 ≈ kW.
- Range per hour ≈ kW × 0.9 efficiency ÷ 0.16 kWh/km. On 10 A that's about 13 km.
Cheat sheet
Power and range by outlet
| Outlet or charger | Current | Voltage | Power | Range per hour |
|---|---|---|---|---|
| Standard power point | 10 A | 230 V | 2.3 kW | ~13 km |
| Dedicated 15 A outlet | 15 A | 230 V | 3.45 kW | ~19 km |
| Type 1 portable charger | 8 A | 230 V | 1.8 kW | ~10 km |
| 7 kW wall charger (single-phase) | 32 A | 230 V | 7.4 kW | ~42 km |
| 22 kW wall charger (three-phase) | 32 A × 3 | 400 V | 22 kW | Limited by the car's onboard charger (often 11 kW) |
Worked example
From kW to hours
Question: how long does a 60 kWh battery take from 20% to 80% on a 10 A power point?
Energy needed: 60% of 60 kWh = 36 kWh into the battery. Power into the battery: 2.3 kW × 0.9 = 2.07 kW. Time: 36 ÷ 2.07 ≈ 17.4 hours.
On 15 A: 36 ÷ (3.45 × 0.9) ≈ 11.6 hours. For your car, see charging times by model.
Why 10 A, not more?
Why you can't just pull more from a power point
A standard Australian power point and its plug are rated at 10 A. A portable charger with a 10 A plug is designed to stay within that for hours. Chargers that claim 16 A from a 10 A plug, or adapters that put a 15 A plug in a 10 A socket, exceed the outlet's rating. More power needs a higher-rated outlet installed by a licensed electrician.

DetailsQuestions
Frequently asked
How many kW does a normal power point supply?
About 2.3 kW: 230 volts × 10 amps. In practice voltage varies a little, so expect 2.2–2.4 kW.
What's the difference between kW and kWh?
kW is the rate of power (how fast energy flows); kWh is an amount of energy. A 2.3 kW charger running for 10 hours delivers 23 kWh.
How many amps does an EV charger draw?
A portable charger on a 10 A plug draws up to 10 A; on a 15 A plug, up to 15 A. A 7 kW single-phase wall charger draws 32 A on a dedicated circuit.
How many km does 1 kWh give an EV?
Roughly 5–7 km for a typical EV, depending on the car, speed and weather. Our figures assume 16 kWh per 100 km, or about 6.25 km per kWh.
