EV Charging Cost FAQ
Answers to common questions about charging tariffs, battery sizing and petrol savings in Australia.
How much does it cost to charge an electric car in Australia?
Charging costs depend on where you plug in. Charging at home on solar power costs around $0.05 to $0.08/kWh (opportunity cost), while off-peak home grid power is typically $0.15 to $0.22/kWh (about $9 to $13 for a full 60 kWh charge). Public DC fast chargers generally range from $0.50 to $0.85/kWh ($30 to $51 for a full charge).
How much money do you save switching from petrol to an EV?
An average Australian motorist driving 15,000 km per year typically spends $2,500 to $3,200 annually on petrol (assuming 9.5 L/100km at $1.90-$2.10/L). Charging an EV primarily at home costs between $450 and $750 per year, yielding annual fuel savings of $1,800 to $2,500.
What is the cheapest way to charge an electric car in Australia?
The cheapest method is home daytime charging powered by your rooftop solar system, followed by a dedicated off-peak or EV controlled load electricity tariff (often offered between 12am and 6am).
Why does charging speed slow down above 80% on public fast chargers?
Lithium-ion batteries accept power quickly when low, but taper their charging rate substantially between 80% and 100% to protect cell longevity and manage battery heat. For long road trips, it is faster and cheaper to unplug at 80% and drive to the next fast charger.
