How Much Does It Cost to Charge an Electric Car in Australia?

If you are weighing up an electric vehicle against your next internal combustion engine car, the running cost is usually a big factor in your decision.

Charging an electric car in Australia costs anywhere from a few dollars to around fifty bucks. But here’s the crucial part: where you charge matters more than what vehicle you drive.

The figures below are estimates for the costs of charging an EV in Australia, since it’s impossible to give a one-size-fits-all approach with so many electric vehicles available and charging stations all across the country. Your actual cost depends on your electricity plan, your charger type, and your car’s battery size.

Cost of Charging an Electric Vehicle at Home

Most EV drivers do most of their charging at home overnight as part of their daily driving routine, and this is by far the cheapest way to do it.

Your applicable electricity rate depends on your plan, but on a standard flat electricity tariff in South East Queensland, expect to pay somewhere around 25-35 cents per kWh. Move to an EV-friendly or off-peak plan, and that can drop to 10-20 cents per kWh for charging done late at night.

A typical mid-size EV uses about 15 to 20 kWh of battery capacity to travel 100km, so a full charge for a small electric vehicle generally costs between $10 and $25 on a standard rate, and considerably less charging overnight on a cheaper plan.

How Charging Time Affects the Cost

Home charging is slower than public fast charging, but that is exactly why it costs less. A full overnight charge on a home Level 2 charger typically takes 4 to 10 hours, depending on your EV battery size, which fits comfortably inside a normal off-peak window, so you are not paying a premium for speed you do not actually need overnight.

Why Do Public Charging Stations Cost More?

Public charging stations almost always cost more than plugging in at home, because you are paying for the convenience and the speed as much as the electricity itself.

• Public AC charging (the kind you find at shopping centres, car parks, and office blocks) typically comes in at around 30-40 cents per kWh, close to a standard home rate.
• Public DC fast charging (the kind built for topping up on a longer trip) typically costs 40-65 cents per kWh, roughly two to three times a home off-peak rate.

A full charge on a fast charger for a mid-size EV can cost anywhere from $25 to $40, depending on the network and how fast the charger runs.

The fastest EV chargers can quickly recharge a battery from near-empty to 80% in around 20 to 30 minutes, which suits a road trip, and the moments when range anxiety actually matters, far better than it suits your daily commute.

Most rapid charging station networks in Australia now support Tesla and non-Tesla vehicles through the same connector standard, so brand is less of a factor at a public charger than it used to be.

Keep an eye on where you park, too: some public chargers sit inside paid parking areas near shopping centres, so factor the paid parking fees in on top of the charging cost, and several networks add an idle fee if you leave the car plugged in for an extended period after it finishes charging.

What Affects EV Charging Costs?

The final figure varies depending on a handful of factors more than any other:

• Your electricity tariff. A flat kWh tariff and an EV-specific or time-of-use plan can differ by 15 cents or more per kWh, which adds up fast over a year of daily charging.
• When you charge. Charging during off-peak tariffs is consistently the cheapest option, and it also usually falls outside peak periods, when the grid has the most spare capacity.
• Your car’s efficiency. A smaller, lighter EV can use noticeably less energy per 100km than a heavier SUV, the same way a small petrol car uses less fuel than a large one.

Charger Types and Their Power Output

• Level 1 (a standard power point) has the lowest power output and is the slowest way to charge.
• Level 2 (a home wallbox or public AC charger) is the average rate most owners actually use day to day.
• Level 3 / DC fast costs more per kWh than a home wallbox, simply because you are paying for speed and site infrastructure on top of the electricity.

Solar power at your home changes the equation entirely. Charging during daylight hours off your own solar panels can push your real cost per kilometre close to zero, which is the biggest single lever most homeowners can pull.

Costs of EV Charging vs Petrol

This is usually where the electric vehicle case gets made or broken, so it is worth doing the maths plainly rather than waving at a vague “it’s cheaper” claim. It also matters for on-road costs beyond fuel, since a smaller weekly outlay is one of the clearest ownership savings an EV offers, popular electric cars included.

Unleaded petrol in Queensland is currently costing around $2.00 to $2.10 a litre, so a single tank on a mid-size car can cost past $100. A typical petrol car uses roughly 7 to 10 litres per 100km, which puts petrol running costs at approximately $14 to $21 per 100km.

An EV charged at home on a standard rate runs closer to $4 to $7 per 100km, and drops to roughly $1.50 to $4 per 100km on an off-peak plan. For a driver covering 12,000 to 15,000km a year, that gap alone typically adds up to $1,000 to $1,700 a year back in your pocket, before you even factor in solar.

This holds whether you are driving a mainstream model like a Tesla Model 3 or Y, a Hyundai Ioniq electric, or something further up the range like a Porsche Taycan, since the saving comes from the electricity price gap, not the badge on the car.

A plug-in hybrid sits in between: plug-in hybrid EVs have a much smaller battery than a full electric car, so a full charge costs less, but the petrol engine still takes over for longer trips once that charge runs out.

Charge for Next to Nothing With Home Solar

The genuine cost-cutter in this whole picture is running the car off your own solar panels while the sun is up, rather than buying every kWh from the grid. If your system is already generating more than the house is using, that surplus goes into the car for close to nothing instead of being exported for a low feed-in tariff.

It is the same principle that makes a solar battery worth it for a household’s general power use, just pointed at the driveway instead of the meter box.

Homeowners who pair solar with a smart EV charger that shifts charging into the sunniest part of the day tend to see the lowest real-world running cost of anyone in this article, well under the off-peak grid figures above.

Getting the Right Charger Installed at Home

A car that ships with a standard “granny cable” can technically be charged from a normal power point, but it is slow, usually adding only 10 to 15km of range per hour, and it is not what most households actually want to live with.

A proper Level 2 home charger changes that. It typically adds 25 to 40km of range per hour, which is enough to fully charge most EVs overnight, and it charges more efficiently than a standard socket over time. EV batteries tend to charge a little faster and lose a little less capacity to heat over long periods when the current is properly managed by dedicated charging hardware rather than a household socket.

Installation needs a licensed electrician, and typically runs $1,500 to $5,000 depending on your switchboard, how far the cable has to run and what your home’s power supply allows, so get that scoped properly rather than guessing off a national average.

We install home EV chargers across Brisbane and South East Queensland, including Tesla Wall Connectors, the myenergi Zappi, which can prioritise solar automatically, and Fronius Wattpilot chargers. Browse the full range on our EV chargers page.

The Bottom Line on Charging Costs

Where and when you charge matters more than which EV you drive. Home charging beats public charging, off-peak beats standard rate, and solar beats grid power every time, so the households paying the least to charge are usually the ones who have stacked all three rather than relying on the car alone to deliver the savings.

Frequently Asked Questions

How much does it cost to fully charge an electric car in Australia?

For most mid-size EVs, expect somewhere between $10 and $25 on a standard home electricity rate, or as little as $6 to $12 on an off-peak plan. The exact figure depends on your battery size and your electricity rate.

Is it cheaper to charge an EV at home or in public?

Home charging is almost always cheaper. Public AC charging is roughly in line with a standard home rate, while public DC fast charging typically costs two to three times more, because you are paying for speed and convenience rather than just the electricity.

How much cheaper is an EV than a petrol car to run?

On current Queensland fuel prices, a petrol car generally costs $14 to $21 per 100km to run, against roughly $4 to $7 to cover the same distance on a home charge at a standard electricity rate, or $1.50 to $4 on an off-peak plan. Over a year of average driving, most owners see somewhere between $1,000 and $1,700 come off their annual running costs.

Does charging speed affect how much I pay?

Yes. The faster the charger, the more you generally pay per kWh, because that price also covers the network’s equipment and site costs, not the electricity alone.

Can solar panels make EV charging free?

Not quite free, since most homes still draw some grid power overnight or on cloudy days, but plugging in while your panels are producing can take your real cost per kilometre down close to zero, especially once your system generates more than the house needs.

Do I need a special charger installed at home to save money?

You do not strictly need one, since any EV can be charged from a standard power point. A proper Level 2 charger is what makes overnight charging fast enough to be practical, and pairing it with solar and an off-peak or EV electricity plan is what actually delivers the savings above.
