Charging an electric car at home is simple and similar to charging a phone

You can charge your electric car at home using either a standard wall socket or a dedicated AC fast charger (often referred to as a 'wallbox' charger). A standard wall socket will do the job, but it will take several hours to add 100km of driving range. This may be enough for many owners who travel less than 100km on average each day.

If you regularly travel longer distances, you may want to install a dedicated home EV charging unit for faster and more efficient charging. Known as Level 2, a home charging unit will provide dedicated AC charging for EVs from about 7kW (on single-phase power) up to 22kW (three-phase), which is much faster than Level 1 (2kW). A single-phase 7kW EV charging unit will add about 35-40km of driving range per hour, delivering enough for most vehicles' average daily use in an hour or so and a full recharge overnight.

Charging your electric car at home is convenient and cheaper than taking it to a power station. It's also cost-effective because it shouldn't require additional installation. However, it's a good idea to have a qualified electrician check your home's electrical wiring and circuitry to ensure it can handle the load.

A standard wall socket or a dedicated AC fast charger can be used

Electric vehicles (EVs) can be charged at home using a standard wall socket or a dedicated AC fast charger. The standard wall socket is a regular power outlet, also known as a Level 1 charger, which provides a typical charge rate of 1 to 4 km every 10 minutes. This means it will take several hours to add 100 km of driving range, which may be sufficient for those who travel less than 100 km per day.

The dedicated AC fast charger, often referred to as a 'wallbox' charger, provides faster and more efficient charging. This type of charger is known as Level 2 and can provide single-phase power of about 7 kW, or three-phase power of up to 22 kW. A single-phase 7 kW charger will add about 35 to 40 km of driving range per hour, typically providing enough charge for most vehicles' average daily use in an hour or so, and a full recharge overnight.

The Level 2 AC fast charger is much faster than the standard wall socket and can reduce charging time significantly. This type of charger often comes with its own tethered cable and plug, typically a universal Type 2 connector compatible with all new electric cars in Australia. However, untethered options with a socket for removable cables are also available to suit different plugs, including Type 2 and Type 1.

Charging an electric car at home offers convenience and cost savings. Home charging eliminates the need to visit electric stations frequently and can be more cost-effective than charging at public stations. Additionally, charging at home during off-peak hours or using smart charging features can further optimise energy use and reduce costs.

It is important to note that before setting up a home charging station, it is recommended to have a qualified electrician inspect the home's electrical wiring and circuitry to ensure it can handle the load. Using a dedicated circuit for charging is advised to avoid overloading. Additionally, if you park your car on the street, your options for home charging may be limited.

The cost of charging at home is significantly less than filling a tank with petrol

Electric vehicles (EVs) are increasingly popular in Australia, with many buyers attracted by the prospect of lower running costs compared to petrol or diesel cars. Charging an EV at home is generally much cheaper than filling a tank with petrol, although there are some important factors to consider.

Firstly, the cost of charging an EV at home depends on the applicable electricity rate. In Australia, electricity retailers typically charge between 20 and 35 cents per kilowatt-hour (kWh). To calculate the total cost of charging an EV battery, you would multiply the battery size by the electricity rate. For example, charging a 60kWh battery at a rate of 30 cents per kWh would cost $18.

Secondly, the speed of charging affects the overall cost. A dedicated Level 2 AC home charger, also known as a "wallbox", can deliver charging speeds of up to 22 kilowatts (kW), significantly faster than the standard 2.4 to 7 kW available from a regular wall socket. However, faster charging rates are generally more expensive, and Level 2 chargers typically cost between $950 and $3,000, with additional installation costs.

Thirdly, the cost of charging an EV at home can be reduced to zero if the electricity is sourced from solar power, as long as the charging is done during the day when sunlight is available. Even without solar power, charging during off-peak hours can result in significant savings, as electricity prices during these periods are often below 20 cents per kWh.

Finally, it is worth noting that while home charging is generally more cost-effective than filling up with petrol, public charging networks can also be utilised when necessary. Some public charging stations are free to use, while others offer varying rates depending on factors such as location, charging speed, and time of day.

Charging at home is convenient and cheaper than taking it to a power station

Charging your electric car at home is a convenient and cost-effective option. While public charging stations are becoming more widely available in Australia, they may not always be easily accessible. If you have off-street parking, you can charge your electric vehicle (EV) from a regular power outlet, known as a Level 1 charger. This is a simple and affordable option, as it doesn't require additional installation. However, it may not be practical for longer commutes or trips, as it provides a slower charge rate of 1 to 4 km every 10 minutes.

For faster and more efficient charging, you can install a dedicated home EV charging unit, known as a Level 2 charger. These units provide AC charging from 7kW to 22kW, adding 35 to 40 km of driving range per hour. This is much faster than Level 1 charging and should deliver enough range for most vehicles' average daily use in an hour or so. Level 2 chargers typically come with a tethered cable and plug, with universal connectors compatible with most new electric cars.

Charging your EV at home is not only convenient but also cost-effective. Electricity retailers in Australia charge between 20 and 35 cents per kWh, which is significantly cheaper than the average cost of filling a tank with petrol. If you generate your electricity through renewable solar energy, the cost to charge your EV is essentially zero, as long as you charge during the day. Additionally, charging at home allows you to take advantage of off-peak hours and smart charging features that optimise energy use, further reducing your costs.

While installing a dedicated home EV charger comes with additional costs, it can save you money in the long run. The price of a Level 2 charger ranges from $950 to $3000, depending on the model and installation fees. Some car companies even offer free installation when you purchase an EV. By investing in a home charging unit, you can enjoy the convenience of charging your EV from the comfort of your home, avoiding the need to rely solely on public charging stations.

Home charging units are faster than Level 1 charging and bring other benefits

While charging your electric vehicle (EV) at home using a standard wall socket is possible, it is a slow process. This is known as Level 1 charging and provides a typical charge rate of 1 to 4 km every 10 minutes. This means it will take several hours to add 100 km of driving range.

Upgrading to a Level 2 AC home charging unit brings many advantages. Also known as 'fast charging', a home charging unit provides dedicated AC charging for EVs from about 7 kW (on single-phase power), up to 22 kW (three-phase), which in both cases is much faster than Level 1 (2 kW). A single-phase 7 kW EV charging unit will add about 35 to 40 km of driving range per hour, which should deliver enough for most vehicles' average daily use in an hour or so, and a full recharge overnight.

The convenience of a home charging unit is another benefit. Wall-mounted home EV chargers are usually tethered with a cable and fully set up to recharge your electric car as soon as you park at home. This means you can keep your portable/mobile charger in the car for emergencies.

The cost of installing a home charging unit can be high, ranging from $950 to $3,000, plus installation. However, many car companies include free installation when you purchase an EV, and charging at home is usually about half the price of rapid charging.

In addition, if your electricity at home is harnessed via renewable solar energy, the cost to charge your EV is zero (as long as you charge it during the day when it is sunny). Combining solar energy with a home charging unit can, therefore, bring significant cost savings.
