Australian homes have three charging options: a standard 10A power point (no install required, slow), a dedicated 15A outlet (~3.6kW, installed by a licensed electrician), or a hardwired 7kW wallbox (~7.4kW, the fastest a single-phase home can go). For daily charging, a dedicated outlet or wallbox removes the speed constraint a standard power point has.
All three use your home's 240V supply. The difference is the circuit amperage and whether a licensed electrician needs to run a new circuit from your switchboard. The 10A option uses whatever outlet is already there. The other two require an electrician.
For most EV owners, the wallbox is the long-term answer. It adds enough range overnight to cover a week of typical driving from a single fill. If budget or switchboard capacity is a constraint, the 15A outlet is a solid middle step.
Three ways to charge an EV at home
The three home charging methods aren't equal in speed, but they all run off the same 240V household supply. What differs is the amperage of the circuit and whether you need a new electrical circuit installed.
Knowing what your home already has helps. Most Australian homes come with 10A power points as standard. A 15A outlet and a hardwired wallbox both need a licensed electrician to run a new circuit from your switchboard.
A standard power point works, but 10A is slow
A standard Australian household power point runs on a 10A circuit. At 240V, that is roughly 2.4kW. A portable EVSE (the cable that comes with most EVs) plugs straight in with no install needed.
That's slow. A 2.4kW charge adds around 10 to 15 kilometres of range per hour. For a 60kWh battery at 20% charge, a full overnight charge of eight hours adds roughly 80 to 120km. That covers light daily use but leaves little buffer for higher-mileage days.
Running a power point hard for years wears older outlets out. Before using a 10A outlet as your regular charging socket, have a licensed electrician check it. An outlet that gets warm under steady load needs replacing.
A 15A outlet gets you overnight range without a full wallbox
A dedicated 15A outlet delivers 240V at 15 amps, which works out to roughly 3.6kW. That is 50% faster than a standard power point and enough to add 15 to 25 kilometres of range per hour.
Over a typical overnight charge of seven to eight hours, a 15A outlet adds 105 to 200km. More than enough. For most Australian drivers who cover under 60km a day, you'll wake up with a full charge every morning.
Installing a 15A outlet requires a licensed electrician to run a dedicated circuit from your switchboard to a weatherproof outlet near where you park. Not a DIY job. It's prohibited under Australian electrical regulations. A dedicated 15A outlet install guide covers what the job involves and what affects cost.
The 15A outlet is the most common mid-range choice: it costs less than a full wallbox and covers most real-world driving needs. If you drive more than 100km a day or want a faster top-up buffer, the 7kW wallbox becomes worth the extra investment.
A 7kW wallbox is the fastest a typical Australian home can go
A dedicated EV wallbox wired to a 32A circuit delivers 240V at 32 amps. That works out to about 7.68kW. In practice, wallboxes are rated at 7kW or 7.2kW to allow for minor supply variation. This is the top speed for single-phase AC charging on a standard Australian home supply.
Most Australian homes are on single-phase electricity. Unless your home has already been upgraded to three-phase supply, 7kW is the fastest home charging rate you can get.
A 7kW charger adds 25 to 35km of range per hour. An overnight charge of seven to eight hours adds 175 to 280km, which is enough to fully charge most EVs currently sold in Australia. See the 7kW vs 22kW guide if you are comparing wallbox power ratings before buying.
A licensed electrician hardwires the wallbox to a dedicated 32A circuit from your switchboard and mounts the unit near your parking space. Before installation, they check your switchboard capacity to confirm your home can take a 32A circuit. If a panel upgrade is needed, they quote for that too. See the full ev charger installation guide for what the assessment covers.
Overnight charging adds more range than most drivers expect
Most EV drivers charge the same way they charge their phone: plug in when you get home, wake up with a full battery. Simple. The car draws what it needs and stops when it hits the target.
The maths works in your favour. A 7kW charger running for eight hours delivers up to 56kWh. That is enough to fill a typical EV battery from empty. No management needed.
Even the 15A outlet at 3.6kW delivers around 26kWh over seven hours. That is well above typical daily use for most drivers. Plenty of headroom.
The overnight model also cuts the habit of topping up at public fast-chargers for daily use. You use the public network for long trips. Your home charger handles everything else.
Smart chargers and solar let you charge on cheaper power
A smart EV charger connects to your home Wi-Fi and lets you set charging windows from an app. The most common use: set it to start after 11pm, when many electricity plans offer off-peak rates. Off-peak charging cuts your per-kilometre energy cost compared to charging during peak evening hours.
If your home has solar, a smart charger can run during the day when your panels are making surplus power. Instead of sending that surplus to the grid at a low feed-in rate, you put it straight into your EV battery. Some smart charger systems link to solar inverters and adjust the charge rate in real time.
A basic wallbox has none of that. It charges whenever it's plugged in. If off-peak savings or solar use matters to you, check the smart vs basic charger guide before you buy.
For homes with solar, the right setup can make EV running costs very low. A dedicated solar EV charging guide covers how to size the system and what the integration looks like in practice.
Your installer confirms what your home can take before you buy a charger
Before buying a wallbox or booking a 15A outlet install, a licensed electrician checks your switchboard. Three things matter: whether your switchboard has room for a new dedicated circuit, whether it has a free breaker slot, and whether you are on single-phase or three-phase supply.
Older switchboards with ceramic fuses rather than circuit breakers often need an upgrade before a new circuit can be added. The electrician spots this on the site visit. They quote for the upgrade alongside the charger install if one is needed.
Getting a site check before you buy a wallbox saves you from purchasing a unit that won't work with your switchboard or phase supply. Most electricians who do EV installs include a switchboard check as part of their quote.
Frequently asked questions
Yes. A standard 10A Australian power point works with the portable cable that comes with most EVs. It delivers roughly 2.4kW and adds around 10 to 15km of range per hour. Slow, but usable. Good for top-ups and occasional use. For daily charging, most drivers move to a 15A outlet or a dedicated wallbox.
Yes. A dedicated 15A outlet delivers roughly 3.6kW and adds 15 to 25km of range per hour. A seven-hour overnight charge covers 105 to 175km, which is more than enough for most daily driving. A licensed electrician installs a dedicated 15A circuit from your switchboard.
On a 7kW wallbox, most EVs go from near empty to full in six to eight hours. On a 15A outlet at 3.6kW, the same charge takes eight to twelve hours depending on battery size. Most drivers just plug in when they get home. Full battery in the morning. No timing needed.
Yes. Any hardwired installation, including a dedicated 15A outlet or a wallbox, requires a licensed electrician under Australian electrical regulations. Every state. Every territory. You cannot legally run a new circuit yourself. The standard 10A power point is the only option with no install needed.
For most EV owners, yes. Charging at home means waking up to a full battery every morning, which removes the need to stop at public fast-chargers for daily commutes. A 15A outlet is the lower-cost starting point. A 7kW wallbox is the better fit if you drive more than 100km a day or want overnight headroom for a larger battery.
The lowest hardware cost is the standard 10A power point: no install needed, just use the cable that came with your EV. But it's the slowest option. The next step up, a dedicated 15A outlet, costs less than a full wallbox install and gives you 50% more speed. For long-term running cost, a smart charger set to charge off-peak lowers your energy cost no matter which outlet you use.
A 7kW charger (7.68kW on a 32A single-phase circuit) adds roughly 25 to 35km of range per hour. An eight-hour overnight charge adds 200 to 280km. For most EVs with a 50 to 77kWh battery, that is a full charge from empty. That's it for single-phase. The 7kW rate is the ceiling for a standard Australian home unless you upgrade to three-phase supply.
You need a smart EV charger with solar integration or a scheduled charging window. Set it to run during peak solar hours. Some smart chargers link to solar inverters and adjust the charge rate in real time based on surplus output. A dedicated solar EV charging guide covers the full setup and sizing in practice.
Most homes can start charging tonight. Not after an upgrade. Not after a site visit. Right now, with the cable that came with the car.
The real question is which option fits how you drive and how much you want to invest. A standard power point is zero install, zero cost, and slower than most daily drivers want, but it's already there. A 15A outlet is the middle ground: a single circuit from your switchboard, a weatherproof outlet near where you park, and enough overnight speed that the battery is full by morning without you thinking about it. A wallbox is the upgrade that removes every constraint: faster fill, any EV, any battery size, any distance. One conversation with a licensed electrician tells you which of those your home can take and what it will cost.
