So you've joined the EV revolution – congratulations! But now you're facing the frustrating reality of slow charging speeds from your standard wall socket, or perhaps you're tired of hunting for public charging stations. The solution? A dedicated home EV charger that transforms your garage into your personal charging station, saving you time and hassle while maximizing your electric vehicle experience.
This comprehensive guide will walk you through everything you need to know about home EV charging in Australia, from understanding the technical jargon like kilowatts (kW) and kilowatt-hours (kWh) to selecting the perfect charging solution for your specific needs. By the end, you'll have the knowledge to make informed decisions about powering up your EV at home.
Why Bother with a Dedicated Home Charger? (Beyond the Standard Socket)
Speed
Standard power points charge at a snail's pace of 2-3kW, adding just 10-15km of range per hour. Dedicated home chargers deliver 7kW or more, meaning you can add 40-100+ kilometers of range each hour depending on your setup.
Convenience
No more public charging station hunting or waiting. Your car charges while you sleep, ensuring you start each day with maximum range.
Safety
Purpose-built EV chargers include advanced safety features to protect your home's electrical system and your vehicle from power fluctuations, overheating, and electrical faults.
Smart Features
Many smart chargers connect to your home Wi-Fi, allowing you to monitor charging remotely, schedule charging during off-peak hours, and even integrate with solar systems.
Cost-Effectiveness
By leveraging off-peak electricity rates, often priced significantly cheaper per kWh (kilowatt-hour), you can dramatically reduce your charging costs compared to daytime or public charging options.
Charger Types & Key Electrical Terms Explained
Understanding the Lingo (Before We Dive In):
- Volts (V): Think of this as electrical 'pressure'. In Australia, standard home voltage is around 230-240V.
- Amps (A - Amperes): This is the electrical 'current' or the rate of flow. A standard power point safely provides 10 Amps (10A), while dedicated circuits for chargers handle more (e.g., 15A, 32A).
- Phase: Refers to how electricity is delivered to your home. Single-phase provides one electrical pathway (~230V), while three-phase provides three separate pathways, allowing for higher power delivery. Most homes have single-phase, but three-phase allows for faster EV charging.
- Kilowatts (kW): This measures the rate or speed of power delivery. It's calculated by multiplying Volts and Amps (and dividing by 1000 to get kilowatts). Higher kW means faster charging. (Think of kW as how fast water flows into a bucket).
- Kilowatt-hours (kWh): This measures the amount of energy used or stored over time. Your EV's battery capacity is measured in kWh (e.g.,60kWh battery), and your electricity bill charges you per kWh consumed. (Think of kWh as the total amount of water in the bucket).
Comparing Level 1 and Level 2 Charging
| Feature | Level 1 Charging | Level 2 Charging |
|---|---|---|
| Connection Type | Standard 10A power point or 15A outlet | Dedicated 32A circuit (single-phase) or 16A/32A (three-phase) |
| Power Output | 2.3 kW (10A) to 3.6 kW (15A) | 7.4 kW (single-phase) to 22 kW (three-phase) |
| Charging Speed | 10-15 km range per hour | 40-120+ km range per hour |
| Installation | No installation required for 10A, basic electrical work for 15A | Requires professional installation |
| Best For | Occasional charging, PHEVs, overnight charging for short commutes | Daily EV use, larger batteries, faster turnaround |
| Energy Delivery | ~2.3–3.6 kWh per hour | ~7–22 kWh per hour |
| Example Product | 15A Type 2 portable charger | 7kW or 22kW portable chargers |
Power Up: Single-Phase vs. Three-Phase Homes
What's the Difference?
Single-phase supplies one path of ~230V electricity. Three-phase supplies three separate paths, allowing more power delivery potential – enabling higher kW chargers (like 22kW) to run efficiently by drawing Amps across multiple phases.
Typical Australian Homes
Most residential properties have single-phase power, which typically limits home charging to around 7.4 kW. However, newer homes, properties with workshops, or homes that have had electrical upgrades may have three-phase.
How to Check Your Supply
Look at your switchboard – a single-phase home will have one main switch, while three-phase will have three (or a single switch that's wider and controls three phases). When in doubt, ask your electrician during quotation.
Upgrade Costs
Converting from single to three-phase typically costs between $1,000-$3,000+ depending on your location, property access, and local network requirements. This isn't just for EV charging – it benefits homes with multiple high-power appliances like air conditioning systems and pool equipment.
Impact on Charging
Single-phase typically limits home charging to ~7.4 kW, sufficient for overnight charging that adds 40-60km of range per hour. Three-phase is needed for wallboxes or portable chargers aiming for 11 kW or 22 kW, which can add over 100km of range per hour.
Choosing Your Weapon: Selecting the Right Charger Hardware
Power Needs (kW)
Match the charger's kW output to your home's power supply (single/three-phase) and your car's maximum AC charging capability. There's no point installing a 22kW charger if your car only accepts 7kW AC or you only have single-phase power. Always check your car's specifications for maximum onboard AC charging rate.
Circuit Requirement (Amps)
Ensure the electrical circuit installed has the correct Amp rating for the charger (e.g., a 7kW charger typically requires a 32A circuit). This is crucial for safety and performance.
Tethered vs. Untethered (Fixed Cable vs. Socket Only)
- Tethered units have permanently attached cables – convenient but less flexible if you change vehicles with different connector types.
- Untethered units have a socket where you plug in your own cable – more adaptable for future vehicles but slightly less convenient.
Portable Options
For flexibility without permanent installation, consider portable charging options:
- A 7kW portable charger drawing 32A from a suitable outlet delivers the same power as many wall-mounted units.
- A 22kW portable charger connected to a three-phase outlet provides the fastest possible home AC charging.
- Adaptable options like the FlexPro can connect to various outlets with different Amp ratings, making them perfect for home and away use.
Smart Features
Consider whether you need:
- Wi-Fi connectivity for remote monitoring and control
- Load balancing to manage power use alongside other appliances
- Solar integration to maximize self-generated electricity use
- Time-of-use scheduling to take advantage of off-peak electricity rates
- RFID access for shared chargers
Durability and Installation Location
Australian weather can be harsh – ensure your chosen charger has appropriate IP ratings (water and dust resistance) if it will be installed outdoors. Look for IP54 as a minimum, preferably IP65 for fully exposed locations.
The Installation Journey: From Quote to Charge (Focus on Wallboxes & Outlets)
Step 1: Initial Assessment
Contact qualified electricians for a site assessment to determine the best location and what electrical work is needed. This process applies whether you're installing a wallbox or the dedicated high-Amp outlets needed for faster portable chargers.
Step 2: Check Your Electrical Capacity
Your electrician will assess whether your home's existing supply has enough capacity for the charger. They'll check:
- Available capacity on your switchboard
- Whether a new dedicated circuit is needed
- If an electrical supply upgrade might be required
Step 3: Choose Installation Location
Consider:
- Proximity to your parking spot (cable length is typically 5-7 meters)
- Access to sufficient power supply
- Protection from weather if necessary
- Cable management to prevent tripping hazards
Step 4: Obtain Quotes and Approvals
Get detailed quotes from multiple electricians. Be aware that some installations may require approval from your electricity distributor, especially for higher-powered chargers.
Step 5: Installation Day
A straightforward installation typically takes 2-4 hours, including:
- Installing a dedicated circuit from your switchboard
- Mounting the charger or installing the high-amp outlet
- Testing and commissioning the system
- Providing documentation and usage instructions

- Level 2 portable chargers: $700-$1,500 (7kW-22kW options)
- Basic wallbox chargers: $800-$1,500 (7kW single-phase)
- Advanced wallbox chargers: $1,500-$3,000+ (higher power or smart features)
Installation Costs
- Simple installations: $500-$1,000 (where existing capacity and nearby access is available)
- Complex installations: $1,000-$2,500+ (requiring significant cable runs, switchboard upgrades, etc.)
- Three-phase power upgrade: $1,000-$3,000+ (if required for higher-powered charging)
Running Costs
Calculate running costs by multiplying your electricity tariff (cents per kWh) by the amount of energy (kWh) added to your car's battery. For example, charging a 60kWh battery from empty at 25 cents per kWh would cost $15.
Portable Charger Advantage
If you already have a suitable high-Amp outlet, portable chargers offer significant savings by avoiding the installation cost associated with a dedicated wallbox circuit. However, if you need that outlet installed, costs may be comparable to a wallbox installation.
