As more Australians switch to electric vehicles (EVs), many wonder about the cost of charging their cars at home. Unlike petrol, which has a straightforward price per litre, EV charging costs vary based on factors like battery size, electricity rates per kilowatt hour (kWh), and vehicle efficiency. While charging at home is often the most convenient and cost-effective option, it’s important to ensure your electrical system can handle the load. That’s where experienced electricians come in—they can evaluate your home’s wiring and install the right charging station safely and effectively.
The type of charging setup you need can also vary depending on the vehicle you own, since larger batteries and different charging capacities often require a more tailored installation. Home EV charging in Australia is generally cheaper than using public EV charging stations or DC fast chargers, especially when paired with off-peak tariffs or a home solar system. Still, the exact charging cost can vary based on where you live, your energy provider, the time you charge, and the type of EV charger you install. Whether you’re driving a Tesla, BYD, Hyundai, or MG, knowing the cost to charge your electric vehicle helps you plan better, estimate your monthly running expenses, and make smarter energy choices.
In this guide, we’ll break down the real cost of charging an electric vehicle at home in Australia, including per kWh pricing, state-based electricity rates, cost comparisons across popular models, and tips for reducing your EV charging bill.
EV Charging in Australia – What It Means for Homeowners
What Is Home EV Charging and How Does It Work?
Home EV charging refers to the process of replenishing your electric vehicle’s battery using a standard residential power source. Instead of relying solely on public EV charging stations, many Australians choose to charge their electric vehicles at home using either a regular power outlet or a dedicated EV charger. This approach offers unmatched convenience, especially for overnight charging, where you simply plug in your EV after returning home and wake up to a fully charged battery.
Charging your electric car at home also allows you to take advantage of cheaper electricity rates, including off-peak tariffs and solar generation if you have a home solar system installed. For most EV drivers in Australia, home charging is the most economical and flexible option available.
Level 1 vs Level 2 Chargers – What’s Right for You?
There are two primary types of home EV charging systems used across Australian households: Level 1 and Level 2, understanding EV charging types can help you choose the right setup.
Level 1 chargers plug directly into a standard 230V power outlet and typically deliver around 2.0 to 2.4 kW. This method is slow, often requiring more than 24 hours for a full charge depending on battery size, which is why many EV owners want to know exactly how long it takes to charge an electric car under different charging setups. Those curious about typical EV charging time can find a range depending on model and charger type.
Level 2 chargers require a dedicated charging unit connected to a higher-capacity circuit, often delivering 7.2 kW or more. They can charge an electric vehicle up to three times faster than Level 1 and are ideal for drivers who need quicker charging times or have larger EV batteries, making EV charger installation a popular home upgrade.
Comparison Table: Home EV Charging Options
Charger Type | Voltage | Charging Speed | Installation Needed | Ideal For |
---|---|---|---|---|
Level 1 | 230V (standard) | 2.0–2.4 kW (slow) | None | Occasional/light daily use |
Level 2 | 240V (dedicated) | 7.2 kW and above | Yes (electrician required) | Daily use, faster turnaround, larger batteries |
What Affects EV Charging Costs?
The actual cost of charging your electric vehicle at home depends on several technical and economic variables. While electricity rates are often the focus, a complete picture includes multiple interrelated factors.
Key factors influencing EV charging cost at home:
- Battery size – Larger batteries require more energy to fully charge. A 40 kWh battery will cost less to fill than a 75 kWh one.
- Electricity tariff – Whether you’re on a flat rate, time-of-use (TOU), or EV-specific energy plan will directly affect your cost per kWh.
- Vehicle efficiency – Some electric cars travel further per kilowatt hour. For instance, an EV with 15 kWh/100 km efficiency is cheaper to run than one using 20 kWh/100 km.
- Charging time – Charging during peak hours can cost significantly more than using off-peak or overnight rates.
- Charging system efficiency – A small percentage of electricity is lost as heat during charging. Typical loss ranges between 10% and 15%, depending on the charger and vehicle.
Depending on the charger and vehicle, efficient charging may also depend on whether your electrical switchboard supports higher loads. Contact our team at Calibre Connect and we can handle electrical switchboard upgrades to support the higher demand required for EV charging.
Understanding these factors helps EV owners estimate their real-world charging expenses and choose the right energy plan or charging schedule to minimise cost.
Electricity Prices by State – How Much You’ll Actually Pay
Electricity costs in Australia vary by state and energy provider, and they play a major role in determining how much it costs to charge an electric vehicle at home. If you live in Sydney, it also helps to understand how your average electricity bills in Sydney compare to national rates, since these figures directly affect long-term EV charging expenses. For EV owners, understanding your local per-kilowatt-hour (kWh) rate is essential when estimating the real cost to charge your car. Whether you’re using a flat-rate tariff or a time-of-use plan, electricity prices can differ significantly between regions and even within a single state.
Current Home Electricity Rates by State (NSW, VIC, QLD, etc.)
Electricity rates fluctuate depending on where you live, the type of energy plan you’re on, and whether your usage includes solar offsets or off-peak pricing. Below is a snapshot of average residential rates across major states.

These figures represent averages, and actual rates may differ based on your plan, energy retailer, and whether you’re eligible for discounts or solar feed-in benefits.
How Much Does 1 kWh Cost in Your Area?
While state averages provide a general guide, the price per kilowatt hour that you pay can vary based on several factors. EV drivers should be aware of how their specific situation influences the cost of electricity used for home charging.
Key variables that affect your electricity rate:
- Tariff type – Flat-rate plans charge the same rate 24/7, while time-of-use (TOU) plans offer cheaper off-peak pricing and higher peak rates.
- Solar integration – If you use a home solar system, daytime charging may effectively reduce your cost per kWh to near zero.
- Energy provider – Different retailers offer varying base rates and discounts, including special EV-friendly plans.
- Distribution zone – Even within one state, electricity prices may vary by region due to infrastructure costs and regulatory differences.
Understanding these factors helps EV owners choose the most cost-effective charging strategy, whether that means switching plans, charging at night, or using solar generation during the day.
EV Charging Cost Estimates by Vehicle Type
To put it all into perspective, here’s how much it may cost to fully charge a few popular EVs in Australia, based on average battery size and state-average per-kWh rates.
EV Model | Battery Size (kWh) | Avg Rate (¢/kWh) | Estimated Full Charge Cost (AUD) |
---|---|---|---|

BYD Atto 3 | 60.5 | 32 | $19.36 |
Hyundai Kona EV | 64 | 29 | $18.56 |
MG ZS EV | 50.3 | 31 | $15.59 |
Nissan Leaf | 39 | 33 | $12.87 |
These estimates assume 100% charging from the grid at standard residential rates. If you use off-peak tariffs or solar generation, your actual cost to charge an electric vehicle at home may be significantly lower.
How to Calculate EV Charging Cost Per km and Per Month
Understanding how much it costs to drive an electric vehicle on a daily or monthly basis is just as important as knowing the cost to fully charge it. Most EV owners in Australia want to know what they’ll spend per 100 kilometres and what their charging bill might look like over a typical month of driving. These costs depend on your vehicle’s efficiency, your electricity tariff, and your overall mileage.
Energy Consumption per 100 km by EV Model
Electric vehicles vary in how much energy they use per distance travelled. This consumption is usually expressed in kilowatt-hours per 100 km (kWh/100 km), similar to how petrol cars are measured in litres per 100 km. A lower number means greater efficiency and lower charging costs.
Here’s a look at the average energy consumption of popular EVs in Australia:
EV Model | Battery Size (kWh) | Avg Consumption (kWh/100 km) | Notes |
---|---|---|---|
Tesla Model 3 RWD | 60 | 13.5 | Highly efficient sedan |
BYD Atto 3 | 60.5 | 15.6 | Compact SUV |
Hyundai Kona EV | 64 | 14.7 | Compact SUV with good range |
MG ZS EV | 50.3 | 17.5 | Less efficient but affordable |
Nissan Leaf | 39 | 18.0 | Older tech, higher usage |
These numbers represent typical combined driving conditions. Actual efficiency will vary depending on your speed, terrain, and driving habits.
Home Charging Cost Per 100 km in AUD
To estimate how much it costs to charge an EV for 100 km of driving, simply multiply your car’s energy consumption by your electricity rate per kilowatt hour.
For example, if your EV uses 15 kWh/100 km and your electricity rate is 30 ¢/kWh, the cost would be:
15 × 0.30 = $4.50 per 100 km
Common cost-per-100 km estimates using standard rates:
- Tesla Model 3 at 13.5 kWh/100 km = $4.05
- BYD Atto 3 at 15.6 kWh/100 km = $4.68
- MG ZS EV at 17.5 kWh/100 km = $5.25
- Nissan Leaf at 18 kWh/100 km = $5.40
Charging at home is still significantly cheaper than fuelling a petrol car, which often costs $10 to $15 per 100 km depending on fuel prices and vehicle efficiency.
Monthly Cost Estimate Based on Average Mileage
If you drive regularly, it helps to estimate your monthly EV charging cost based on how far you typically travel. The table below shows sample monthly costs for different driving ranges using a home electricity rate of 30 ¢/kWh.
Monthly Distance | Avg EV Consumption (kWh/100 km) | Monthly kWh Used | Charging Cost (AUD) |
---|---|---|---|
1,000 km | 15 | 150 | $45.00 |
1,500 km | 15 | 225 | $67.50 |
2,000 km | 15 | 300 | $90.00 |
These are conservative averages. Your actual monthly cost may be lower if you charge overnight on off-peak rates or use a home solar system. In some cases, drivers using solar can reduce their cost to near zero during daytime charging.
How EV-Specific Tariffs and Off-Peak Plans Reduce Charging Costs
One of the biggest advantages of charging an electric vehicle at home is the ability to take control of your energy costs. Many electricity retailers in Australia now offer EV-specific tariffs and time-of-use plans that give drivers the chance to charge their vehicles during off-peak hours at heavily reduced rates. These tailored energy plans can cut your charging bill by 40 percent or more compared to using a standard residential rate.
Top EV Tariffs in Australia by Provider
Several major electricity providers offer energy plans designed specifically for EV owners. These plans may include cheaper overnight charging, sign-up bonuses, or discounts tied to smart charging habits.

Overnight Charging with Off-Peak Plans (As Low as 8c/kWh)
Time-of-use (TOU) plans separate the day into peak, shoulder, and off-peak periods. Charging your EV at night can offer substantial savings compared to charging during the day or peak hours.
Benefits of off-peak charging:
- Off-peak rate example: 8 ¢/kWh vs standard rate of 30 ¢/kWh
- Cost to fully charge a 60 kWh EV:
- Standard rate: 60 × 0.30 = $18.00
- Off-peak rate: 60 × 0.08 = $4.80
- Savings per full charge: $13.20
- Monthly savings: Over $60 for drivers charging 15 times per month
Smart EV chargers and scheduling apps make it easy to automate charging during these low-cost windows, ensuring you always maximise your energy savings.
Real Cost Comparison: Standard Rate vs EV Plan
To see how much difference an EV-specific plan can make, here’s a side-by-side comparison of charging costs under two different electricity scenarios:
Charging Scenario | Electricity Rate | Cost to Fully Charge (60 kWh) | Monthly Charging Cost (1,500 km at 15 kWh/100 km) |
---|---|---|---|
Standard Flat Rate | 30 ¢/kWh | $18.00 | $67.50 |
EV Off-Peak Plan (e.g. Origin) | 9 ¢/kWh | $5.40 | $20.25 |
Switching to an EV-friendly plan not only reduces the cost per full charge but also lowers your monthly energy bills significantly. For high-mileage EV drivers, the difference could mean hundreds of dollars saved each year.
Comparing Home Charging vs Public Fast Charging
While most EV drivers in Australia prefer the convenience and cost savings of charging their vehicle at home, public charging stations offer flexibility when you’re away from home or need a faster top-up. The cost difference between home charging and public charging is often significant, especially when using ultra-rapid DC chargers.
Cost per kWh at Home vs DC/AC Public Chargers
Electricity rates at home are generally lower than those at public EV charging stations. Residential charging costs usually fall between 25 to 35 cents per kilowatt hour, depending on your energy plan and time of use. In contrast, public charging stations can charge up to three times that amount, particularly when using DC fast chargers or branded ultra-rapid networks.
Here’s a comparison of typical per-kWh pricing across common charging methods:
Charging Method | Typical Cost per kWh | Notes |
---|---|---|
Home charging (standard) | 25–35 ¢ | Based on residential electricity plans |
Home charging (off-peak) | 8–15 ¢ | EV-specific or time-of-use rates |
Public AC charger (22 kW) | 40–50 ¢ | Slower than DC, suitable for longer stops |
Public DC fast charger (50–150 kW) | 60–80 ¢ | Common at shopping centres, highways |
Tesla Supercharger (250 kW) | Up to 92 ¢ | One of the fastest, but expensive |
Home charging remains the most affordable option, especially when combined with off-peak rates or solar generation.
Total Cost for Full Charge Comparison (Home vs Public)
Using a 60 kWh EV battery as an example, the total cost to fully charge the vehicle varies significantly depending on where and how you charge.
Cost to fully charge a 60 kWh EV:
- Home standard rate (30 ¢/kWh): 60 × 0.30 = $18.00
- Home off-peak rate (10 ¢/kWh): 60 × 0.10 = $6.00
- Public AC charger (45 ¢/kWh): 60 × 0.45 = $27.00
- Public DC fast charger (75 ¢/kWh): 60 × 0.75 = $45.00
- Tesla Supercharger (92 ¢/kWh): 60 × 0.92 = $55.20
The price difference becomes even more pronounced for frequent long-distance drivers or those without access to home charging.
When Does Public Charging Make Sense?
Despite the higher cost, public EV charging plays an important role in supporting electric vehicle adoption, particularly for drivers who:
- Live in apartments or units without dedicated home charging access
- Are travelling long distances or on road trips where battery range is a concern
- Need a fast top-up during errands, work, or emergencies
- Are enrolled in loyalty programs or subscription models that reduce public charging costs
Networks like NRMA EV Fast Charging, Evie Networks, Chargefox, and Tesla Superchargers continue expanding their coverage across Australia, making public charging more accessible even outside metro areas.
