You have just brought home a new EV, and now the questions start. Do you need a Level 2 charger or a three phase one? Should you upgrade your power supply? Around the homes we look after in Donvale, Doncaster and across Melbourne’s east, this is one of the most common things people ask us, and the way the question is usually phrased hides a small misunderstanding.
Here is the part worth knowing up front: Level 2 and three phase are not two competing options. Three phase is simply one way to run a Level 2 charger. So the real decision is not “Level 2 or three phase” at all. It is whether your Level 2 charger should run on single phase or three phase power. Once you see it that way, the choice gets a lot simpler.
Not Sure Which Charger You Need?
Our licensed electricians check your switchboard and how you drive, then match you to the right Level 2 setup, single phase or three phase, no guesswork.

What a Level 2 Charger Actually Is
A Level 2 charger is the wall mounted unit most people picture when they think of home EV charging. It connects directly to your switchboard through a dedicated circuit, rather than a standard power point, and it charges far quicker than the portable cable that comes with the car. It is also the unit we fit on most home EV jobs, because the portable charger that ships with the vehicle was never meant to carry the daily load.
Every Level 2 charger runs on either single phase or three phase power. That is the only branch in the road. A single phase Level 2 charger typically delivers around 7kW, which adds roughly 40 to 50 kilometres of range an hour. A three phase Level 2 charger can deliver up to 22kW, which adds well over 100 kilometres an hour. Same category of charger, very different speed, decided entirely by the power feeding it.
Single Phase vs Three Phase: What It Means at Home
Most Melbourne homes are wired for single phase power. Newer builds, larger properties and many commercial sites tend to have three phase. You can usually get a rough idea by looking at the main switch on your switchboard: one main switch generally means single phase, while three sitting side by side points to three phase. We always confirm this properly during a site visit before recommending anything, because guessing here is what quietly leads to wasted money.
A few honest points for the decision:
- Single phase 7kW is plenty for most households. Charging overnight easily covers a normal daily commute, even for a larger battery.
- Three phase only helps if your car can use it. Plenty of popular EVs cap their AC charging at 7kW or 11kW, so a 22kW charger gives you nothing extra.
- Upgrading to three phase is a real job. If your street and home are single phase, adding three phase means new supply and switchboard work, which adds genuine cost.
- Three phase makes sense when you already have it, or when you cover very high daily distances, or run a business with several vehicles.

So Which One Do You Actually Need?
For the large majority of homeowners, a single phase Level 2 charger is the right answer. It is cheaper to install, it suits the power most homes already have, and it charges quickly enough that your car is full each morning without you thinking about it.
Three phase earns its place in a smaller set of cases. You already have three phase power at the property. You drive serious distances every day. You run a commercial site or a small fleet and need vehicles turned around faster. Or you are doing a renovation or new build and want to set the place up for the future while the walls are open, which is far cheaper than retrofitting later.
The smartest charger is not the fastest one on paper. It is the one matched to your car, your home and how you actually drive.
What we would steer you away from is paying for three phase you cannot use. A 22kW charger feeding a car that only accepts 7kW is money spent for no benefit, and after years on the tools across the eastern suburbs, it is the mistake we see catch people out most.
Get the Right Setup the First Time
EV charging should be simple once it is set up correctly, and the setup is where a licensed electrician earns their keep. The wrong charger or an underdone install can mean slow charging, safety risks or a costly redo down the track.
