What To Consider With EV Charging At Home?

What To Consider With EV Charging At Home?

Do you have an electric vehicle and are considering the convenience and efficiency of installing an at home EV charging station? EV charging at home offers both convenience and long-term savings, however it's important to understand the different things to consider for a safe, efficient and suitable setup. 

What are the different types of EV chargers?

EV chargers are categorised based on their different power supply. In Australia, there are three types of EV chargers, Level 1, Level 2 and Level 3 which are the DC Fast chargers. 

Level 1 Charging

Level 1 chargers use a regular 240V household power outlet, typically delivering around 1.4-3.7kW of power. This is the slowest EV charging method but may be sufficient for drivers with minimal daily travel needs. Using this method, your electric vehicle can gain around 10–20km of driving range per hour of charging. A full charge using Level 1 can take anywhere from 10-16 hours, depending on the size of the EV’s battery. While it’s convenient because it doesn’t require any special equipment or installation, it’s best suited for overnight or emergency charging. These are best for:

  • Hybrid vehicles with electric and standard options
  • Occasional or emergency home use
  • Drivers with short commutes and long overnight parking availability

Level 2 Charging

Level 2 chargers offer a significant upgrade in speed and efficiency. These chargers typically operate between 7.2kW to 22kW, depending on your home or building’s electrical infrastructure. They are professionally installed and require a dedicated circuit and often a wall-mounted charging unit.

At 7.2kW, Level 2 charging can add approximately 30–50 km of range per hour, while a 22kW charger can deliver up to 100–120 km per hour—making it ideal for overnight charging or quick daily recharges. These are best for:

  • Daily EV drivers who need reliable overnight charging
  • Homes with solar systems or battery storage
  • Workplaces or commercial properties with fleet vehicles

Level 3 – DC Fast Charging

DC Fast Chargers deliver direct power at very high rates, ranging from 50kW to 350kW, depending on the charger and the EV’s capability. These are not typically suitable for home installation due to their infrastructure and cost requirements, but are commonly found at highway service stations, urban fast-charging hubs, and commercial charging sites.

At 50kW, a DC fast charger can add around 150–200 km of range in 30 minutes, while a 150kW charger can deliver up to 300 km of range in as little as 15–20 minutes. These are best for:

  • Long-distance drivers needing quick top-ups
  • Highway travel and intercity road trips
  • EVs that support high-capacity DC charging
  • Commercial fleets

How long will it take to charge my EV?

The time it takes depends on three factors including, battery size, charging level and battery health. On average the charging time is: 

  • Level 1: 10-16 hours
  • Level 2: 2-5 hours 
  • Level 3: 10-20 minutes

Will you need to upgrade your power supply?

Your home’s current electrical systems may need to be upgraded to support an EV charger depending on your property and appliances. A qualified electrician can conduct a site inspection to assess your current setup and ensure your home can accommodate an electric vehicle charging station. If you’re not driving frequently, a standard power point may be sufficient or you may wish to install a specific electric vehicle charger. 

It's important to contact an electrician to make sure that your charging equipment meets Australian standards, this ensures your safety and also your vehicles warranty. 

What does it cost to charge an EV from your home or business? 

Charging your electric vehicle at home is typically the most cost-effective option, unless you happen to live near a free public charging station. The overall cost of home EV charging can vary based on several factors, including your vehicle's battery size, your daily driving habits, your electricity rates, and when you choose to charge. 

Consider charging in off-peak hours 

Charging your electric vehicle during off-peak hours of the day will allow you to reduce your electricity costs and increase long-term savings. Many electricity providers charge lower rates at different times of the day which you can take advantage of.

Consider smart charging 

In recent years, smart charging has become popular to provide automatic charging when your EV is plugged in when the electricity is the cheapest. It's important to only charge the battery when it needs it, keep the battery charge level between 20-80% for optimal battery performance. If you already have solar panels at home, charging your EV with solar energy can also significantly reduce running costs

Consider government rebates and incentives

Some Australian states and territories offer incentives for EV charger installation or home energy upgrades that can reduce your out-of-pocket costs. These rebates are subject to change, so it’s a good idea to check with your local authority or a licensed installer.

Where should I install my EV charging station at home?

Location matters when installing your EV charger. Ideally, your charger should be:

  • Close to where you park your vehicle (garage, carport, or driveway)
  • Protected from the weather (many chargers are weather-rated, but cover is still ideal)
  • Mounted at a height that allows easy access to the cable
  • Installed with enough clearance to avoid trip hazards

Most chargers are wall-mounted, but some other options are available if wall space is limited. You’ll also want to consider the cable length to ensure it comfortably reaches your car’s charging port, regardless of how you park. A professional will adhere to Australian standards for EV charger installations to cover everything from the type of charger to regulations for ongoing maintenance. 

Are you located near a public EV charging station?

When considering electric vehicle charging it's beneficial to know whether you are located near a public charging station. If you are, before planning an at home station you might want to consider: 

  • How fast your car will charge depending on your needs and schedule
  • The best locations in your area 
  • The availability of chargers that are compatible with your vehicle 

If there are plenty of public charging options you may want to start with these before installing your at home system.
