A simple, modern guide to home EV charging in Australia — covering outlet types, charging speeds, safety tips and how to choose the right setup for your home.
Key Takeaways
- Most EV owners charge at home using either a portable charger or a wall charger.
- Charging speed depends on your outlet (10A, 15A, 32A) and your EV’s onboard charger.
- 10A = slow charging, 15A = moderate, 32A = fast single‑phase charging.
-
Portable chargers offer flexibility for rentals, travel and everyday home use, while wall chargers provide a fixed installed option.
- Smart charging features help reduce electricity costs and support long‑term battery health.

Charging your EV at home is one of the simplest, safest and most cost‑effective parts of owning an electric vehicle. Whether you’re using a portable charger or a wall‑mounted unit, the goal is the same: deliver power to your EV in a way that’s efficient, reliable and suited to your home.
This guide breaks down the essentials — outlet types, charging speeds, safety tips and smart‑charging features — so you can understand exactly how home charging works and choose the setup that fits your lifestyle. It’s written for everyday drivers and keeps things clear, modern and beginner‑friendly.

Understanding Home EV Charging
AC Charging
AC (Alternating Current) is the type of electricity supplied by Australian homes. When you charge at home, your EV receives AC power and converts it into DC using its onboard charger. This slower, controlled charging method is ideal for overnight top‑ups and long‑term battery health.
Onboard Charger
Your EV’s onboard charger determines the maximum AC charging speed your car can accept (e.g., 7kW, 11kW). This is why two EVs plugged into the same outlet can charge at different speeds — the onboard charger sets the limit.
Charging Power (kW)
Kilowatts (kW) measure how quickly energy flows into your EV. Higher kW means faster charging. Most home setups fall between 2.4kW and 7.2kW depending on your outlet and charger.
Amperage (Amps)
Amps (short for amperage) describe how much electrical current can safely flow through an outlet or charger. The higher the amps, the more electricity your EV can draw at once — which directly affects charging speed. Australian homes typically use 230–240V power, so increasing the amperage is what increases total charging power (kW).
A 10 amp outlet provides a slow, steady charge, while 15 amp, 20 amp and 32 amp outlets allow faster charging because they can deliver more current. This is why the type of outlet you plug into has such a big impact on how quickly your EV charges at home.
Putting it all together
When you charge at home, AC power flows from your wall outlet into your EV, where the onboard charger converts it into DC and stores it in the battery. The speed of this process depends on two things: the outlet you’re using (10A, 15A or 32A) and the maximum AC charging rate your EV can accept. Understanding these basics makes it much easier to choose the right home setup — whether you’re using a portable charger or planning an upgrade.
This diagram provides a simple visual overview of how an electric vehicle works. It highlights the five key components inside an EV: the electric motor, inverter, transmission, EV battery and onboard charger. Each component is illustrated with a short explanation of its role, helping beginners understand how energy flows from the charger, through the battery and inverter, and ultimately to the motor that drives the wheels.
Now that you understand how home charging works, the next step is knowing which outlets can support it — and how each one affects charging speed.
Home Outlet Types Explained
10 amp (10A) Standard Outlet (2.4kW)
The most common outlet in Australian homes. Ideal for slow overnight charging or light daily driving. Great for renters or anyone who doesn’t need fast charging every day.
15 amp (15A) Outlet (3.3kW)
A heavier‑duty outlet with a larger earth pin. Provides more stable charging and is commonly found in garages, workshops and caravanning setups. A good middle‑ground for faster overnight charging.
32 amp (32A) Single‑Phase Outlet (7.2kW)
A high‑capacity outlet installed by a licensed electrician. Delivers fast AC charging for most EVs and is the most popular upgrade for homeowners wanting reliable daily charging without installing a full wall charger.
20 amp (20A) and 32 amp (32A) Three‑Phase Power (11kW–22kW)
Available in some Australian homes. Supports the fastest AC charging speeds, but only if your EV’s onboard charger can accept 11kW or 22kW. Ideal for large households or EVs with bigger batteries.

Home Charging Options
Option 1: Portable EV Charger
A portable charger plugs directly into your home outlet and adapts to your available power. It’s ideal for rentals, travel, multi‑location charging, and everyday home use. Charging speed depends entirely on the outlet you plug into (10A, 15A or 32A).
Option 2: Wall Charger (EVSE)
A permanently installed charger that provides a dedicated charging point. Wall chargers offer consistent power delivery, tidy cable management and optional smart features. Best for households wanting a fixed, long‑term solution.

How to Charge Your EV at Home (Step‑by‑Step)
- Park your EV close to your outlet or wall charger.
- Plug the charger into the outlet (or ensure the wall charger is powered).
- Connect the Type 2 plug to your EV.
- Check your EV’s dashboard to confirm charging has started — most EVs display estimated time to full.
- Leave the EV to charge until you reach your preferred battery level.
Tip: Most EV owners charge overnight to take advantage of off‑peak electricity rates.
Home Charging Safety Tips
- Use RCM‑certified chargers to ensure compliance with Australian electrical safety standards.
- Use dedicated circuits for 15A and 32A outlets.
- Avoid using extension cords or power boards for EV charging.
- Ensure outlets are in good condition and not overloaded.
- Keep chargers off the ground and away from water.
- If an outlet feels warm during charging, stop and have it inspected.
- Have an electrician inspect older wiring if unsure about your home’s capacity.
Smart Charging: Save Money & Protect Your Battery
Many EVs, portable chargers and wall chargers support smart charging features such as:
- Scheduled charging (off‑peak rates)
- Charge‑limit settings (e.g., 80% for daily use)
- Solar‑aware charging
- Load balancing
- App‑based monitoring and control
These features help reduce electricity costs, protect your battery and give you more control over your charging routine — even without installing a wall charger.
Frequently Asked Questions
How long does it take to charge an EV at home?
It depends on your outlet and your EV’s onboard charger.
-
10A: ~10–20 hours

15A: ~7–14 hours
-
32A: ~4–8 hours
-
11kW/22kW (three‑phase): ~2–6 hours (for compatible EVs)
Do I need a wall charger?
Not necessarily. Many EV owners use portable chargers daily, especially with 15A or 32A outlets. Wall chargers are helpful if you want a fixed installation, faster speeds or advanced smart features.
