Electric vehicles (EVs) are surging in popularity in Australia, offering a sustainable transportation option. While public charging stations are expanding, one of the key benefits for EV owners is the ability to conveniently charge their vehicle at home.
Installing a home EV charger provides flexibility and cost savings. This guide explains the process for Australian households looking to electrify their garage.
EV Charging Basics
There are a few key considerations when installing a home EV charging station:
Types of Chargers
There are different levels of EV chargers:
- Level 1 – Slow charging via a regular wall outlet. Best for overnight top-ups.
- Level 2 – Faster charging via a dedicated 240V circuit. The preferred option for convenient daily home charging.
- DC Fast Charge – Rapid 30min charges at public stations. Not currently practical for residential use.
For most Australian homes, a Level 2 charger offers the best balance of speed and practical installation.
Power Supply Capacity
Before installing an EV charger, it’s important to have a qualified electrician assess your electrical system’s capacity. EV chargers have high power demands, so your supply needs to be robust enough to support the additional load.
Upgrades like a new metre board may be required if capacity is insufficient.
Dedicated Circuit
A dedicated circuit is ideal for powering an EV charger cleanly and safely. This isolates the high electrical load, avoiding tripped breakers or power fluctuations.
Step-By-Step Installation Guide
Once you understand the basics, here is how to tackle the installation process:
Choose an Experienced Electrician
EV charger installation is complex, involving high voltage electrical work. Hiring a qualified electrician experienced with EV chargers is strongly advised. They’ll ensure Australian standards and safety regulations are met.
Determine the Location
Consider the best location for the wall-mounted charger near your parking area. Optimise for:
- Convenience of charging your EV
- Protection from weather
- Minimal distance from the switchboard
- Safety and accessibility
Take into account any hazards like flooding or vehicle impact.
Mount the Charger Securely
Your electrician will securely mount the charging unit on a wall or sturdy pole. The mounting height and position must allow convenient charging access without ever being strained.
Install the Dedicated Circuit
Your electrician will run wiring from the switchboard to your new EV charger location. This dedicated circuit ensures consistent, uninterrupted power supply.
Choose a Level 2 Charger
Level 2 chargers deliver faster charging speeds by utilising higher 240V power:
- Typically charge 20-60 km of range per hour of charging
- Require installation by a qualified electrician
- Offer convenient daily home charging solution
Level 2 is the preferred option for most Australian households.
Consider Smart Charging Technology
Smart chargers allow app or voice control and can integrate with rooftop solar and battery storage systems. This allows you to maximise self-sufficiency and only draw grid power when needed. Discuss options with your electrician.
Additional Factors to Consider
Charging Speeds
The charging capacity depends on the car model and charger power rating. Most Level 2 chargers deliver 20-60 km of range per hour of charging. Understand your vehicle specs when selecting a charger.
Installation Costs
A typical Level 2 home installation ranges from $1200-$2000 but can vary significantly based on site conditions. Get multiple quotes to find the best value electrician.
Electrical Upgrades
If your home’s electrical capacity is insufficient, upgrades like a new switchboard may be required first. This can add $2000-$5000 to costs. Your electrician will advise if upgrades are needed.
Benefits of Home EV Charging
- Convenience – charge your EV any time at home
- Cost savings – cheaper than public rapid charging
- Speed – faster than a standard wall outlet (Level 2)
- Control – monitor and schedule charging remotely
Installing an EV charger provides freedom and savings for Australian EV owners. Follow this guide and hire a professional electrician for safe, efficient charging at home.
