Wattage basis: The three common home charging levels; 7 kW single-phase covers most owners (~30% of AU homes have three-phase).

Cutting the cost

Charge overnight on an off-peak or dedicated EV tariff, or during the day if your solar is exporting anyway. You rarely need a full charge every night, so top up to your usual daily range instead of filling to the top each time. Set a scheduled start so the car waits for the cheap window, and steer clear of charging through the early-evening peak.

Frequently asked questions

How is the running cost calculated?
Watts ÷ 1,000 × your electricity rate = cost per hour. A ev charger drawing 7,000 W on a 33.1c/kWh tariff costs $2.32 an hour — the calculator above lets you change every input.
Does a higher star rating cut the cost?
Yes — the star rating compresses the power draw or energy per use, which scales this page's figures directly. The low–high band in the table (2,400–22,000 W) roughly spans efficient to inefficient models.
Why does the state matter?
The appliance draws the same power everywhere — but each state's reference usage rate differs, so the same hour of running costs $1.92 in the cheapest state and $2.93 in the dearest. Pick your state above for exact figures.
