For EV owners in Perth, charging at home and using public chargers each have different costs, convenience and practical benefits. Your EV charging cost Perth can depend on your electricity tariff, vehicle efficiency, charging speed, charging habits and whether you have solar.
Understanding these differences can help you choose the most practical way to charge your EV.
The home EV charging cost Perth drivers pay is mainly determined by how much electricity their vehicle uses and the electricity rate at their property.
A simple way to estimate the cost is:
Charging cost = electricity used (kWh) × electricity price per kWh
Your actual electricity use depends on factors such as:
Charging at home can also be convenient because you can plug in when you arrive home and charge overnight without making a separate trip to a charging station.
The public EV charging cost Perth drivers pay varies between charging networks, locations and charger types.
Public chargers may provide AC charging or faster DC charging. DC fast chargers can provide a much quicker top-up than typical home AC charging, making them useful for longer journeys or when you need to get back on the road quickly.
Public charging can be particularly useful if you:
Because public charging fees can vary, it is worth checking the charging network’s current pricing before using a particular station.
Factor | Home EV Charging | Public EV Charging |
Electricity cost | Based on your home electricity tariff | Based on the charging network and pricing |
Solar power | Can use excess solar generation | Generally separate from your home solar |
Charging speed | 7kW AC is common for homes | AC and faster DC options are available |
Convenience | Charge while parked at home | Requires travelling to a charging station |
Regular use | Well suited to daily charging | Useful for top-ups and longer trips |
Installation | Requires suitable electrical capacity | No home installation required |
Best suited to | Overnight and routine charging | Travel and faster top-ups |
Looking at your regular driving habits is more useful than comparing one charging session. For many EV owners, using a home charger for routine charging and public chargers when travelling can provide a practical combination.
For homeowners who regularly drive an EV and have suitable off-street parking, a dedicated home charger can make charging more convenient.
However, installation should not be based on the charger alone. A qualified electrician should assess the property’s electrical capacity, switchboard, cable route, circuit protection and existing household load.
At Willex Electrical, our qualified electricians have hands-on experience installing EV charging systems across Perth homes. We install and commission Tesla, Zappi and Evnex charging systems and assess the electrical requirements before installation.
Our work can include the appropriate dedicated circuit and RCBO protection, switchboard checks, electrical testing, charger commissioning and required electrical compliance documentation. Willex Electrical is a WA-licensed electrical contractor (EC14820), providing electrical services across Perth.
The home EV charging cost Perth homeowners should consider therefore includes both the ongoing electricity used for charging and the electrical requirements of the installation.
The public EV charging cost Perth drivers experience may be worthwhile when convenience or charging speed is more important than routine home charging.
Public charging can make sense for:
For regular Perth driving, a home charger can provide a convenient charging base, while public stations remain useful when your driving takes you beyond your normal routine.
It depends on your home electricity tariff, public charging fees, vehicle efficiency and charging losses. Solar generation can also affect the overall cost of home charging.
It can. Using excess solar generation to charge an EV can reduce the amount of electricity drawn from the grid.
A 7kW charger is a common home charging option, but suitability depends on the property’s electrical capacity, switchboard and existing electricity demand.
Not necessarily, but a dedicated charger can provide faster and more convenient charging. A qualified electrician can assess your property and recommend a suitable setup.
