Installing a home EV charger is the single best investment you can make as an electric car owner. While you can charge from a standard power point, a dedicated Level 2 charger is faster, safer, and smarter. Here's everything you need to know about home EV charger types, costs, installation requirements, and the best options available in Australia.
Level 1 Charging: Standard Power Point
Every EV comes with a portable charger (often called a granny charger) that plugs into a standard 10A power point. It's the slowest option, but it's free — you don't need any installation.
- Power output: 2.4kW (10A @ 240V)
- Charging speed: ~12–15km of range per hour
- Overnight charge (10 hours): ~120–150km of range
- Installation cost: $0 (uses existing socket)
For many Australians who drive less than 50km per day, Level 1 charging is perfectly adequate. Plug in when you get home, wake up to a full battery. However, it's important to use a dedicated circuit — don't run an EV charger off a power board or extension lead.
Level 2 Charging: Dedicated Wall Charger
A Level 2 charger is a dedicated unit hardwired to your switchboard on its own circuit. It's faster, safer, and offers smart features that a standard socket can't provide.
| Charger Type | Power Output | Charging Speed | Time for Full Charge (60kWh) |
|---|---|---|---|
| Single-phase 7kW (32A) | 7kW | ~40km/hr | 8–9 hours |
| Single-phase 7.4kW (32A) | 7.4kW | ~42km/hr | 8 hours |
| Three-phase 11kW | 11kW | ~65km/hr | 5.5 hours |
| Three-phase 22kW | 22kW | ~120km/hr | 2.7 hours |
Most Australian homes have single-phase power, which limits you to 7–7.4kW charging. This is more than sufficient for overnight charging. If you have three-phase power (common in newer homes and some older properties), you can install an 11kW or 22kW charger — though your EV must also support three-phase charging to benefit. Our comparison of single-phase versus three-phase EV chargers explains when the upgrade actually pays off.
Installation Costs
The total cost of a Level 2 home charger installation depends on the charger unit, electrical work, and any switchboard upgrades required:
| Component | Cost Range |
|---|---|
| Wall charger unit (7kW) | $700–$1,500 |
| Installation labour | $500–$1,000 |
| Switchboard upgrade (if needed) | $500–$1,500 |
| Cable run (if long distance) | $200–$800 |
| Total typical cost | $1,500–$2,500 |
Costs are lower if your switchboard is modern, the charger location is close to your meter board, and no trenching is required for underground cable runs.
Smart Chargers: Worth the Extra Cost
Smart chargers cost $200–$500 more than basic units but offer features that can save you significantly more than that over time:
- Scheduled charging: Set your charger to start during off-peak hours automatically, saving 40–50% on charging costs
- Solar diversion: Automatically adjusts charging speed to match available solar excess, maximising free fuel
- Load management: Monitors your household power usage and adjusts charging to avoid overloading your supply
- Energy monitoring: Track exactly how much energy your EV uses and what it costs
- App control: Start, stop, and schedule charging from your phone
Electrical Requirements
Before installing a Level 2 charger, your electrician will assess:
- Available capacity: Your switchboard needs enough spare capacity for a 32A circuit. Older homes may need a switchboard upgrade
- Single vs three-phase: Determines maximum charger power. Check your meter or switchboard, or ask your electrician
- RCD protection: A dedicated Type A or Type B RCD is required for EV charger circuits under Australian standards
- Cable distance: Longer runs between the switchboard and charger location require heavier gauge cable
- Metering: If you want a separate tariff for EV charging (e.g., controlled load), a separate meter may be needed

Key Recommendations
- A 7kW single-phase charger is sufficient for the vast majority of Australian EV owners
- Invest in a smart charger if you have solar or a time-of-use tariff — the savings pay for the premium within 1–2 years
- Always use a licensed electrician who is experienced with EV charger installations
- Get at least two quotes — installation costs vary significantly between electricians
- Consider future-proofing: if you might add solar panels or a second EV, discuss this with your electrician upfront
