AC vs DC Charging: Every Type of EV Charging Explained

AC and DC charging differ in one thing: where the electricity is converted for the battery. AC charging sends mains power to the car and the car’s own onboard charger converts it, so the speed is capped by that small unit, usually 7 or 11 kW. DC charging does the conversion in the cabinet beside the bay and feeds the battery directly, so the car’s battery sets the limit and sessions take minutes instead of hours. Every charging type in Australia, from a power point in a carport to a 350 kW highway unit, is one of those two, and this guide walks through all of them, with our own data on what the cars sold here can actually use and where each type is.

What is the difference between AC and DC charging?

The grid supplies alternating current. A battery stores direct current. Something has to convert one to the other, and where that happens is the whole difference.

AC charging puts the converter in the car. NRMA’s charging explainer puts it plainly: the car’s onboard charger converts the grid’s alternating current to direct current for the battery. That onboard unit is small, so AC charging is slow no matter how big the charger on the wall. NRMA’s own warning is that a 22 kW wall box will not necessarily charge every EV at 22 kW.

DC charging puts the converter in the cabinet. The same NRMA page describes DC fast charging as doing that conversion outside the car, inside the charging unit, which is what allows much higher rates. The car’s onboard charger is bypassed, and the limit becomes what the battery management system will accept.

The ACT Government adds the practical consequence: DC chargers typically have higher power output than AC, so they are often much faster, but also more expensive to use.

The plugs follow the same split. Type 2 for AC, CCS2 for DC on effectively every new EV sold here, with the Nissan Leaf’s CHAdeMO the holdout. Our connector guide covers the plugs; this page is about the power behind them.

Every type of EV charging in Australia

The range-per-hour figures are the ACT Government’s typical speeds: up to 15 km per hour from a 2.3 kW power point, up to 40 km from a 7 kW AC charger, up to 130 km from a 22 kW AC charger and up to 420 km from a 50 kW DC charger. NRMA’s explainer gives a similar spread for home charging, 13 to 22 km per hour from a wall socket and 38 to 45 km from a 7 kW wall box. Treat them as ceilings, the DC one most of all: the ACT’s own rule of thumb, quoted further down, works out to about 300 km an hour from a 50 kW unit. Your car’s own limits, covered below, usually bring them down.

A few rows need a sentence each.

Power point and portable charger. The cable with the control box that came with your car. Slow, but the ACT Government notes an overnight charge from a regular socket can add up to 150 km, and it puts the average Canberran’s driving at about 40 km a day. The portable charger guide covers the 10 A and 15 A versions, and the extension cord guide covers the one thing not to do with it.

Wallbox. A dedicated AC charger on its own circuit. NRMA lists the single-phase version at around 7 kW and three-phase at up to 22 kW, both needing electrician installation. Which one suits your car is the subject of the next section, and our home charging guide and home charger comparison cover the purchase.

Kerbside. For drivers without a driveway. The Australian Renewable Energy Agency funded an Intellihub trial of 50 chargers on street power poles across nine NSW council areas in 2022, aimed at owners of apartments, townhouses and units with no on-site charging, and built for top-ups and overnight charging. The NSW Government’s third kerbside grant round, a $5 million program open from 21 September to 21 December 2026, funds both AC and DC chargers on the kerbside and in council and commercial carparks across 37 eligible council areas, aimed at the parts of NSW with the least off-street parking. Our guide to charging without a driveway has the detail.

DC fast and ultra-rapid. The line between them is a convention, not a standard. Our own dataset counts a site as fast DC from 40 kW. JOLT’s city units are DC too, with CCS2 and CHAdeMO leads and 7 kWh free a day with a service fee per session, so a charger on the street does not always mean a slow one. Our public charging guide covers the networks and the Supercharger guide covers Tesla’s.

Bidirectional. The newest type runs the other way. Vehicle-to-load exports power from the car to appliances. Vehicle-to-home and vehicle-to-grid need a bidirectional charger and, in Australia today, a very short list of approved cars. Our bidirectional charger guide and V2L guide cover what works here now.

What do Level 1, Level 2 and Level 3 mean?

They are American labels. The NSW Government’s Vehicle Emissions Star Rating site maps them for Australia: Level 1 is AC from a regular power point at 1.4 to 3.7 kW, Level 2 is AC at 7 to 22 kW from a dedicated unit on a separate circuit, and Level 3 is DC covering 25 to 350 kW. Australian networks and installers mostly skip the labels and quote AC or DC plus the kilowatts, which is the habit worth copying. “Level 2” tells you nothing about whether the car in front of it will take 7 or 22.

Which AC speed can your car actually use?

Your car’s onboard AC charger limit: 7 to 11 kW .

This is the figure the AC side of the table above is really measured against. We keep charging specifications for 34 battery-electric models sold in Australia, each verified against the maker or an independent test in August 2026. Their onboard AC chargers break down like this:

The three 22 kW cars are the Toyota bZ4X and both Zeekr 7X variants. Every BYD in the database except the Sealion 7 sits at 7 kW. The Hyundai, Kia, Tesla, Volvo, BMW and Polestar entries sit at 10 to 11 kW, which needs three-phase power to reach.

So the honest answer to “should I buy a three-phase wallbox” is: check this number first. For 31 of the 34 cars, a 7 kW single-phase unit gives you most of what the car can take, and an 11 kW unit gives you all of it. NRMA’s explainer says the same thing in fewer words: there is no point paying for a faster AC setup if the car cannot make use of it.

Which DC speed can your car actually use?

Your car’s peak DC rate: 100 to 150 kW .

Same exercise for the fast side. Peak DC rates across the same 34 cars:

Two things fall out of that table. First, 21 of the 34 cars peak at 150 kW or less, so for most drivers a 150 kW unit and a 350 kW unit are the same charger. Second, these are peak figures, held only for part of the session. The Australian Renewable Energy Agency’s op-ed on charging speed reported in 2023 that the average rate across one ultra-fast network was 60 kW, because few cars could accept more than 100 kW and rates fall as the battery fills. The fleet has moved on since, but the gap between a charger’s label and a session’s average has not closed.

The ACT Government’s rule of thumb is a useful one for planning: on a DC charger, the charger’s kilowatt rating is roughly the kilometres of range it adds every 10 minutes, so a 50 kW unit adds about 50 km in 10 minutes, slowing past 80 per cent. Our guide to how long charging takes has a calculator for your own battery and charger.

Where is each type of charging in Australia?

This is where our charger dataset earns its keep. It holds 1,395 public charging sites as of November 2026, built from Open Charge Map listings plus operator sites we have confirmed, and it records the fastest plug at each one. 787 sites have fast DC, which the dataset counts from 40 kW. The other 608 are AC-only or carry slower DC, which for a road-tripper means a stop measured in hours, not minutes.

Western Australia has the most sites of any state in our dataset and the lowest share of fast ones: two in three WA sites are AC-only or slow DC. Queensland is the reverse, with almost nine in ten listed sites fast DC. Victoria and the ACT have both the density and the speed.

Two more things the data shows. In the six states, 509 of the 739 fast DC sites sit outside the capital-city areas (Sydney, Melbourne, Brisbane, Perth, Adelaide and Hobart, each with its surrounds), so fast charging is mostly a regional network, which is the right way round for the trips it exists for. And the fastest unit listed in each state, in our November 2026 refresh, tops out at 300 kW in the ACT, 350 kW in NSW, Victoria, Queensland, South Australia and Tasmania, 400 kW in Western Australia, and 80 kW in the Northern Territory, where our charging gaps study still finds the country’s longest run between fast chargers. The regional blackspots page lists the towns with no DC at all, and the charger map shows every site with its speed and price.

What does each type cost?

AC is cheaper than DC, and home AC is cheapest of all. A flat home tariff runs about 30 cents per kWh in our cost calculator’s default, an off-peak EV plan about 8 cents, and rooftop solar costs you only the feed-in tariff you give up. Our cost guide does the arithmetic for your car.

In public, the clearest AC-versus-DC comparison is RAA’s South Australian network, one of the few Australian networks that publishes both prices on one rate card. Metro off-peak AC is 33c/kWh and metro off-peak DC is 66c/kWh, exactly double, with a $1 minimum per session and a $1 a minute idle fee at DC sites after a 10-minute grace period. Evening peak, 5 pm to 10 pm, lifts both.

Elsewhere, DC pricing in our tariff dataset runs from Tesla’s 27 to 74c/kWh depending on site and time of day, to NRMA Electric’s location-based 69 to 99c/kWh, with the top of that band at remote Northern Territory sites. Evie’s last announced rates were 50 to 73c/kWh across its AC and DC tiers. Chargefox and Exploren sites are priced by the site owner, and plenty of council and shopping-centre AC posts are free; our free charging directory lists them. How to pay, and the fees that catch people out, is in our guide to paying for public charging.

Which type should you use?

The ARENA op-ed’s argument is the one that holds up: EVs suit charging when convenient, not filling when empty. For anyone who can charge at home or at work, that low-power AC connection should be the first choice, with public DC for the trips that need it.

In practice:

1. Daily driving: AC where the car sleeps. A power point covers the average day. A 7 kW wallbox covers a big day and lets you use a cheap overnight window. Buy three-phase only if your car is one of the few that can use it.
2. Parked anyway: free or cheap AC. Shopping centres, hotels, council carparks. Carry your Type 2 cable, because AC posts are often socket-only. Our Type 2 guide covers the cable.
3. On the road: DC, to 80 per cent. Know your car’s peak rate before you plan around 350 kW units. Charge to 80 and move on; both the ACT Government and NRMA note the taper past 80 per cent, and networks charge idle fees for the car that stays.
4. No driveway: kerbside AC or DC. Check the charger map for the posts and poles near home, and watch the NSW kerbside program if you live in one of its 37 council areas.

The short version: AC is the charger you own, and DC is the charger you visit. Buy the AC speed your car can use, and plan trips around the DC speed your car can take, not the number on the cabinet.
