A clear, modern guide to real EV charging speeds at home — including 10A, 15A, 32A, single‑phase and three‑phase charging in Australia.
Key Takeaways
- 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.
- Most Australian homes support up to 7.2kW (32A single‑phase).
- 11kW and 22kW require three‑phase power and a compatible EV.
- Real‑world km/hour varies by EV efficiency, temperature and battery size.

How EV Charging Speed Works
Home EV charging uses AC power, which is slower than public DC fast charging, but far more convenient, predictable and cost‑effective for daily use. Understanding how fast your EV can charge at home comes down to three key components — and each one plays a different role.
1. Your Outlet (10A, 15A, 32A, Three‑Phase)
Your outlet determines how much electrical current your charger is allowed to draw. A higher‑rated outlet = more available power.
- 10A outlet → up to 2.4kW
- 15A outlet → up to 3.3kW
- 32A single‑phase outlet → up to 7.2kW
- 32A three‑phase outlet → up to 22kW
This is the starting point for your charging speed — your charger cannot exceed what the outlet can supply.
2. Your Charger (Portable or Wall Charger)
Your charger’s job is to convert AC power from your home into a form your EV can use. Portable chargers and wall chargers can both be fast — the difference is not the charger itself, but the power source behind it.
Portable chargers:
- Plug into 10A, 15A, 32A or three‑phase outlets
- Speed varies based on the outlet
- Ideal for flexibility and travel
Wall chargers:
- Hard‑wired to a dedicated circuit
- Provide consistent daily charging
- Often cleaner and more convenient
3. Your EV’s Onboard Charger (The Real Speed Limit)
This is the most important factor — and the one most EV owners don’t realise.
Your EV has an internal AC charger that sets the maximum AC charging speed it can accept.
- If your EV supports 7kW AC, it will never charge faster than 7kW at home — even if you plug into a 22kW three‑phase outlet.
- If your EV supports 11kW AC, you’ll only reach that speed on a three‑phase connection.
- If your EV supports 22kW AC, you’ll unlock the fastest possible AC charging at home.
This is why two EVs plugged into the same outlet can charge at completely different speeds.
Charging Speeds by Outlet Type
10A Outlet (2.4kW)
- ~10–15 km of range per hour
- Best for overnight charging or emergencies.
- No installation required — perfect for renters, apartments, or homes without upgraded wiring. If you drive 20–40 km per day, a slow overnight top‑up is usually enough to keep your battery healthy.
15A Outlet (3.3kW)
- ~15–22 km of range per hour
- Good for daily charging.
- Great for daily commuting. Adds around 15–22 km of range per hour, ideal for topping up after work or overnight if you drive moderate distances.
32A Single‑Phase (7.2kW)
- ~35–45 km of range per hour
- Fastest single‑phase home charging.
- Best for busy households or longer daily driving. Adds around 35–45 km per hour, giving most Australian EV owners enough range for commuting, errands, and weekend trips.
Three‑Phase (11kW–22kW)
- ~50–120 km of range per hour
- Only beneficial if your EV supports 11kW or 22kW AC.
- Ideal for EVs that support faster AC charging. Adds up to 120 km per hour, perfect for drivers who need rapid home charging or have larger‑battery EVs.
Real‑World Charging Speeds (km per Hour)
| Power | Outlet | Approx. km/hour |
|---|---|---|
| 2.4kW | 10A | 10–15 km |
| 3.3kW | 15A | 15–22 km |
| 7.2kW | 32A single‑phase | 35–45 km |
| 11kW | Three‑phase | 50–70 km |
| 22kW | Three‑phase | 90–120 km |
Note: Efficiency varies by EV model, temperature and driving style.
How Long Does It Take to Fully Charge an EV at Home?
Based on a typical 60kWh battery:
| Power | Outlet | Full Charge Time |
|---|---|---|
| 2.4kW | 10A | 20–28 hours |
| 3.3kW | 15A | 14–18 hours |
| 7.2kW | 32A | 8–10 hours |
| 11kW | Three‑phase | 6–7 hours |
| 22kW | Three‑phase | 3–4 hours (EV‑dependent) |
Most EV owners charge overnight and rarely need a full 0–100% charge.
Which Home Charging Speed Do You Need?
Choosing the right home charging speed depends on how far you drive, how often you charge, and whether your home already has upgraded wiring. Here’s a simple, practical breakdown to help you decide.
Choose 10A If:
- You drive short distances (20–40 km/day)
- You only need slow overnight charging
- You live in a rental or apartment with no ability to upgrade outlets
- You want a low‑cost, plug‑and‑play solution
Real‑world example: You get home at 6pm with 40% battery. By morning, you’re back to 80–90% — enough for commuting, school runs and errands.
Choose 15A If:
- You want faster overnight charging without major electrical work
- You don’t want to install a 32A outlet
- You drive moderate distances (40–80 km/day)
- You want a simple upgrade that gives noticeably faster charging
Real‑world example: You drive 60 km/day. A 15A charger adds ~15–22 km/hour, giving you a full recharge in 4–6 hours.
Choose 32A (7.2kW) If:
- You want fast daily home charging
- Your EV supports 7kW AC charging (most EVs in Australia do)
- You have a busy household or longer daily driving
- You want the best balance of speed, convenience and cost
Real‑world example: You arrive home at 30%. A 7.2kW charger gets you back to ~80% before bedtime.
Choose 11kW or 22kW If:
- Your home has three‑phase power
- Your EV supports 11kW or 22kW AC charging
- You want the fastest possible home charging
- You have a large‑battery EV or drive long distances daily
Real‑world example: A 60kWh EV can go from 20% to 80% in around 3 hours at 11kW, or 3–4 hours at 22kW.

Frequently Asked Questions
Is home charging cheaper than public charging?
Yes — home charging is almost always cheaper than public charging, especially when you use off‑peak electricity rates. Most Australian EV owners pay between 20–35 cents per kWh at home, compared to 60 cents to $1.20 per kWh at public DC fast chargers.
Home charging also avoids idle fees, queueing, and peak‑hour surcharges.
Can I charge an EV from a normal power point?
Yes — a standard 10A household outlet works with 10A portable chargers. It’s slow, but perfectly safe when the outlet is in good condition. A 10A outlet adds around 10–15 km of range per hour.
If you drive more than 40–50 km per day, upgrading to a 15A or 32A outlet is recommended.
Do I need three‑phase power?
You only need three‑phase power if your EV supports 11kW or 22kW AC charging and you want the fastest possible home charging speeds. Three‑phase charging can add 50–120 km of range per hour, but only if your EV is capable of using that extra power.
Most EVs in Australia charge at 7kW AC, which works perfectly on single‑phase power.
Final Thoughts
Home charging speeds vary depending on your outlet, charger and EV — but for most Australian homes, 7.2kW (32A single‑phase) offers the best balance of speed, convenience and cost. It’s fast enough for daily commuting, reliable enough for busy households, and compatible with almost every EV sold in Australia.
Three‑phase charging is ideal for EVs that support 11kW or 22kW AC, but it isn’t essential for most drivers. If your EV is limited to 7kW AC, three‑phase power won’t increase your charging speed.
Whether you choose 10A, 15A, 32A single‑phase, or three‑phase, the best home charging solution is the one that fits your driving habits, your home’s electrical setup, and your EV’s onboard charger.
