EV battery sizes range widely from 16kWh to up to 86kWh. The bigger the battery, the further you can drive.
To get the full benefits, you’ll need to check on the capacity of the electricity network supply to your home. The cost to set up your home charging outlet depends on things like your current home electrical design, the electricity tariff and charging options you choose.
Your EV manufacturer will provide the specific charging options available for your car. Depending on which EV you choose and how many kilometres you drive, you may need to upgrade your home’s electricity supply.
The guide below details what type of charger might suit you best:
|Driving distance per week (average)||Charger recommended|
|Less than 200 kilometres||Normal socket connection|
|200-500 kilometres||Dedicated wall-mounted charging unit|
|Over 500 kilometres||Dedicated EV charging point|
Electrical supplies to many homes and buildings in Victoria (especially those built before 1970) may not be enough to support the addition of an electrical vehicle charging load.
In these cases, an upgrade might be needed to make sure charging an EV won’t cause fuses to blow and impact the reliability of supplies to you and your neighbourhood.
We can let you know more about your supplies, if an upgrade is recommended and what the costs will be. Visit eConnect to register your interest and see what the capacity is in your area.
If you contact us as soon as you order your EV, we can work to make sure any upgrades are finished before your new car arrives.
If you’re wanting a dedicated charging unit for your EV, then the charging point in your home will need to be set up by a Registered Electrical Contractor (REC). They will install it in line with Australian Standards and the Victorian electricity rules.
The REC will visit your home and evaluate the wiring, electrical outlets and other hardware needed to support the charging of an EV.
On average, research in Victoria has shown setting up a home charging outlet costs around $1,750 for the charging circuit wiring, and the charging outlet cost can vary from:
Talk to your electricity retailer (the company that sends your electricity bill) about how you can make the most of new, time-of-use tariffs offered by CitiPower and Powercor that can allow you to charge your EV when it is most cost-effective.
Essentially, peak periods on our networks are between 3pm and 9pm daily. So if you can charge your vehicle before or after that time, then you may receive the benefit of lower network costs.
The Electric Vehicle Council is the national body representing the electric vehicle industry in Australia. CitiPower and Powercor are members of this organisation.
Their website offers useful information to help you select electric vehicles including:
Charging times are falling quickly as technology advances. Residential chargers are usually able to fully charge EVs in around six to eight hours, depending on the vehicle’s capacity. This means you can easily charge your car overnight.
Public fast chargers are able to get you back on the road much faster. Leave your car at a charger while you go shopping or to work and in three hours, it’ll be fully charged.
If you charge your EV using electricity generated by your rooftop solar system, then your recharge costs can be further reduced with the added benefit of no CO2 emissions from this renewable energy source.
There are now an increasing number of solar aware charging options available.
These track your solar export and adjust the charging rate of your EV to soak up that excess and charge your EV. It’s a great option when your vehicle is at home during the day.
If you have a battery, then you can charge your EV off the stored solar when the sun doesn’t shine (enough).
Like any other electronics in your home, you need to make sure the equipment used to charge your car is safe.
We also recommend you ask your REC to install a ‘Residual Current Device’ to keep you and your family safe. These devices will turn off the power if they detect a fault. The most common types of safety switches found in homes may not be suitable to protect you from all the faults that an EV or its charger may create.
