You’ve just bought your first EV and you’re excited. When someone asks how you’ll charge it, you say, “There are chargers at the shopping centre. I’ll just use those when I need them.” Your friend who already owns an EV falls silent.
A few months later, you’re in a car park at 7pm, waiting for a DC fast charger. You’re paying more per kWh, and all that fast charging is slowly affecting your battery in ways you didn’t expect.
At PSC Energy, we install home EV chargers with solar systems every week. We know this decision well and will give you a clear answer. Many new EV owners in Australia make this mistake. Home and public EV charging aren’t equal. One should be your main method, while the other works best as a backup.
In this article, you’ll learn about the following:
- How Home EV Charging Works in Australia
- How Public EV Charging Works in Australia
- What DC Fast Charging Does to Your EV Battery
- The Solar Advantage: When Home EV Charging Becomes Almost Free
- When Public Charging Alone Might Work for You
- FAQ: Home and Public EV Charging in Australia
By the end of this article, you’ll get a clear breakdown of how each option works, what they really cost, how DC fast charging affects your battery over time, and when to use each approach.
How Home EV Charging Works in Australia
You have two main ways to charge an EV at home.
The first option is a standard 10A household power point, often called “granny charging.” It gives about 2.4 kW of power, adding around 15 km of range per hour. Charging a 60-80 kWh battery from empty takes 24 to 40 hours, so it’s not a practical long-term solution for most drivers.
The second option is a dedicated Level 2 wall charger. These connect directly to your home’s electrical system and run at 7 to 22 kW. Here’s what that means for you:
- A 7.4 kW single-phase charger adds roughly 40-50 km of range per hour.
- A 22 kW three-phase charger adds roughly 100-120 km of range per hour.
- A 7.4 kW charger fully charges a 60-80 kWh battery overnight in 8-11 hours.
- A 22 kW charger cuts that to around 3-4 hours.
Home EV charger units in Australia cost between $700 and $2,050. Installation adds more, depending on your home’s wiring.
How Public EV Charging Works in Australia
Public charging in Australia falls into two categories: Level 2 AC charging and Level 3 DC fast charging.
Level 2 public chargers (AC)
Level 2 public chargers run at 7 to 22 kW and are found in places like shopping centres, council car parks, hotels, and workplaces. Their charging speed is similar to a home wall charger.
Key things to know:
- Cost: $0.30 to $0.50 per kWh, though some chargers are still free.
- Many Level 2 stations don’t have a cable attached, so you’ll need to bring your own Type 2 to Type 2 cable. A three-phase cable costs about $20 more than a single-phase one and is usually worth the upgrade.
- Some older stations use the Type 1 plug, so you’ll need a Type 1 to Type 2 adaptor, which costs about $150.
- Charger availability depends on the network, and you might not find one free during busy times.
Level 3 public chargers (DC fast charging)
DC fast chargers work at speeds from 25 kW up to 350 kW. For example, a 150 kW charger can take a 60 kWh battery from 20% to 80% in about 25 to 30 minutes.
What you need to know:
- Cost: $0.60 to $0.85 per kWh, depending on the network and speed.
- DC power bypasses your car’s onboard charger and goes straight to the battery. This creates more heat and wears out the battery faster.
- DC fast charging is best for long road trips, not for everyday charging.
Tesla Superchargers
Tesla’s Supercharger network is the most reliable Level 3 network in Australia. V2 Superchargers deliver 40-120 kW. V3 Superchargers deliver up to 250 kW each on a dedicated power supply, so charging speed stays the same even when several cars are charging at once.
- Tesla owners pay $0.70 per kWh, with charges automatically charged to their account.
- Non-Tesla owners can access compatible Superchargers through the Tesla app at $0.85 per kWh, or $0.70 per kWh with a $ 9.99-per-month membership.

What DC Fast Charging Does to Your EV Battery
DC fast chargers send electricity straight into your battery pack at high speed, bypassing your car’s onboard charger. This creates more heat inside the battery cells, and heat is the main enemy of lithium-ion battery health.
Here is what repeated DC fast charging does over time:
- It accelerates the rate at which your battery loses capacity.
- A battery that loses capacity faster delivers fewer kilometres per charge.
- Fewer kilometres per charge means you need to charge more often.
Most EV manufacturers mention in their warranty documents that frequent DC fast charging can reduce your battery’s long-term capacity. Some even limit how many fast charges are covered under warranty.
AC home charging works at a lower, controlled rate through your car’s onboard charger. It creates less heat, causes less wear, and is what most manufacturers recommend for daily charging.
The Solar Advantage: When Home EV Charging Becomes Almost Free
If you have rooftop solar, home EV charging changes the equation entirely.
A solar system produces the most power between about 9am and 3pm. Many modern home EV chargers have a solar smart-charging mode that senses when your system is making extra power and uses it to charge your car instead of sending it to the grid.
Here is why that matters:
- In NSW in 2026, feed-in tariff rates for exported solar sit at roughly $0.05 to $0.10 per kWh.
- Grid electricity to charge your EV costs $0.28 to $0.40 per kWh.
- A solar smart charger redirects surplus generation into your car, replacing expensive grid electricity with energy you would otherwise export at the low feed-in rate.
For solar smart charging to work well, you need:
- A solar system large enough to generate a consistent surplus, typically 10 kW or more.
- A smart charger with a solar charging mode, such as the Sigenergy AC EV Charger, myenergi Zappi, or Fronius Wattpilot.
- An EV that accepts AC charging, which all modern EVs do.
EV owners with solar and a smart charger often pay less than $2 for a full charge. On sunny days, if they charge during peak solar hours, some pay nothing at all.

When Public Charging Alone Might Work for You
There are genuine situations where a home charger is less critical.
You might get by on public charging if:
- You live in an apartment and do not have access to a dedicated car space or strata permission to install a charger. Workplace charging, destination charging, or public Level 2 stations may cover most of your needs. Dedicated apartment EV charging solutions are also available in NSW, including through the ReadySteadyPlug scheme.
- You drive short distances, such as under 30 km a day. A standard power point might be enough to top up overnight, but it’s slow and not ideal for long-term use.
- Your workplace offers free Level 2 charging five days a week. If you do most of your charging at work, you may not need a home charger as much.
Even in these cases, it’s not a good idea to rely on public DC fast charging as your main daily method because of the higher costs and battery wear already discussed.

FAQ: Home and Public EV Charging in Australia
Is home EV charging cheaper than public EV charging in Australia?
Yes, by a lot. Home charging on a standard tariff costs $0.28 to $0.40 per kWh. Public DC fast charging costs $0.60 to $0.85 per kWh, which is about two to three times more for the same energy. With rooftop solar, home charging can cost as little as $0 per kWh or up to $0.10 per kWh.
Can I rely on public EV charging alone in Australia?
You can, but it’s not a smart long-term strategy for most homeowners. Public charging is more expensive, less convenient, and harder on your battery if you use DC fast chargers often. It works well as a top-up on road trips or as a bridge while you set up a home charger.
How long does it take to charge an EV at home in Australia?
A standard 10A power point delivers 2.4 kW, so a full charge on a 60 kWh battery takes 24 to 40 hours, which isn’t practical for regular use. A 7.4 kW Level 2 wall charger charges the same battery overnight in 8 to 11 hours. A 22 kW three-phase charger does it in 3 to 4 hours.
Does DC fast charging damage my EV battery?
Frequent DC fast charging causes your battery to lose capacity faster than AC home charging. The high-speed direct-to-battery delivery generates more heat, and heat degrades lithium-ion cells over time. Occasional fast charging on road trips is fine. Using it as your main daily method will shorten your battery’s life faster than necessary.
What is the cheapest way to charge an EV in Australia?
Charge at home during peak solar hours using a solar smart EV charger. This redirects extra solar power, which would otherwise be exported at $0.05 to $0.10 per kWh, into your car instead. Without solar, charging at home on an off-peak time-of-use tariff is the next best option at $0.15 to $0.22 per kWh.
Can I use solar panels to charge my EV at home?
Yes. A smart home EV charger with a solar charging mode detects surplus solar production and uses it to charge your car. This works best with a 10 kW or larger solar system and a charger that supports solar smart charging, such as the Sigenergy AC EV Charger, MyEnergi Zappi, or Fronius Wattpilot.
What size home EV charger do I need in Australia?
For most single-phase homes, a 7.4 kW Level 2 charger is the standard recommendation. It charges a typical EV overnight and supports solar smart charging. If your home has three-phase power, an 11 kW or 22 kW charger gives you faster speeds for a modest extra cost. A licensed electrician can check your switchboard before installation.
