Start with the daily top-up
A suitable portable setup may cover your daily driving. A dedicated charger gives you more flexibility when you need more energy in less time. Battery size alone does not decide which option you need.
Driving
Estimate the energy used on an ordinary day.
Time
Count the hours available to charge.
Vehicle
Check its AC charging limit and instructions.
Home
Ask an electrician to assess the setup.
Two ways to charge at home
The Australian Government’s charging-equipment guide distinguishes household-outlet Level 1 charging from dedicated Level 2 AC charging. Actual charging power depends on the equipment, vehicle and conditions.
Level 1: a suitable household outlet
Use a compatible portable unit with its control box and approved adapter. An existing power point is not automatically suitable for sustained EV charging.
Level 2: a dedicated AC unit
A dedicated installation can offer higher power, but the vehicle’s onboard AC limit and the commissioned setup still determine what it can use.
- Charging window
- Portable chargingCan work when a suitable setup replaces your daily energy use while the car is parked.
- Dedicated chargerMore useful when you need a larger top-up in a shorter time.
- Usable power
- Portable chargingThe portable unit, approved adapter and outlet determine the available power.
- Dedicated chargerThe home supply, configured output and vehicle AC limit can cap the advertised rating.
- Electrical work
- Portable chargingAn existing outlet and circuit still need assessment for sustained charging.
- Dedicated chargerHave the installation designed and commissioned by a licensed electrician.
- Equipment
- Portable chargingCheck the exact vehicle, charging unit and approved adapter combination.
- Dedicated chargerCheck vehicle compatibility, cable reach and whether the unit is tethered or socketed.
- Controls
- Portable chargingThe vehicle or compatible equipment may support scheduling.
- Dedicated chargerConfirm the exact model’s scheduling, solar and load-management features and any extra equipment.
- Complete cost
- Portable chargingInclude the unit and any assessment or remedial electrical work.
- Dedicated chargerInclude equipment, installation, commissioning and any supply or site work.
How long would your daily top-up take?
Chosen inputs: steady 2.4 kW or 7.4 kW input, 20 kWh/100 km driving consumption and 90% efficiency. These are illustrations, not measured vehicle performance. Many portable units supply less than 2.4 kW.
Time to replace the energy used while driving
- 40 km 8 kWh to the battery
- 2.4 kW example3.7 hours
- 7.4 kW example1.2 hours
- 100 km 20 kWh to the battery
- 2.4 kW example9.3 hours
- 7.4 kW example3.0 hours
- 160 km 32 kWh to the battery
- 2.4 kW example14.8 hours
- 7.4 kW example4.8 hours
Energy to replace = kilometres × consumption ÷ 100. Time = energy ÷ (input power × efficiency). Range per hour = input power × efficiency ÷ consumption × 100. The examples give 10.8 and 33.3 km per hour respectively.
Across 8 hours, these inputs deliver 17.3 or 53.3 kWh to the battery, if it has capacity remaining. Vehicle limits, temperature, state of charge and changing power can alter the result. Follow the vehicle maker’s charging instructions.
Match the option to your routine
- Record daily driving, vehicle energy use and how long the car is normally parked.
- Allow for longer days, shared charging and times when the car is away from home.
- Have an electrician assess the available setup before relying on a charging calculation.
- Compare extra power and supported features with the complete installed price.
If a safe portable setup already covers your routine, there is no fixed deadline to upgrade. If it falls short, take your driving and charging-window figures to the installer. Our home EV charging guide covers the broader planning steps.
Have the electrical setup assessed
The Australian Government’s home-charging guidance recommends licensed-electrician advice and professional installation of a dedicated charger. Ask about outlet condition, circuit and supply capacity, cable routing, protection, commissioning and completion documents.
Leave electrical design, testing, installation and repairs to a licensed electrician. Queensland’s Electrical Safety Office guidance explains why DIY electrical work is unsafe. Check the relevant requirements where you live; this guide supplies no wiring or circuit-design instructions.
Check permissions and installer credentials
For shared parking or rented property, confirm permissions and responsibilities before ordering. The government’s strata resident guide covers working with the owners corporation and landlord. Our apartment charging guide provides further starting points.
Verify the electrical contractor’s licence through the relevant regulator, such as Queensland’s official licence search for Queensland work. The Wombat checks ABNs; you check relevant licences, insurance and experience before hiring.
Compare complete costs
Use the EV charger installation planning and quote checklist to prepare your vehicle, parking, access and charging-window details for comparable proposals.
Include the equipment, electrical assessment, installation or remedial work, any supply changes and optional service fees. Ask which items are fixed, allowed for or excluded. The EV charger quote guide covers scope and attributed installation examples.
For running costs, compare metered electricity, losses and your actual tariff. In a separate illustration, delivering 20 kWh at 90% efficiency draws about 22.2 kWh; at a chosen $0.30/kWh that costs about $6.67. These are chosen inputs, not a market tariff or a quote. Solar charging may also mean giving up export payments.
Check support and written terms
Ask about maintenance, app or subscription fees, fault handling, call-outs, labour and warranty exclusions for the exact model. Keep installation records and check your insurer’s disclosure and coverage requirements.
Choose features you can use
Scheduling may help match a low-rate window; compatible solar control may follow surplus generation. Confirm what the vehicle or exact charger supports, any extra hardware and ongoing fees. Ask the electrician whether load management suits the installation. Do not assume every smart charger provides every feature or guarantees savings.
Compare the exact Australian model
Check connector compatibility, the vehicle’s AC limit, cable reach, supported controls and local support. Use our charger-selection guide for detailed product questions, rather than choosing from the highest advertised power alone.
Follow charging and emergency guidance
Use compatible equipment as instructed by its manufacturer. Do not use extension leads, power boards or improvised adapters. If equipment is damaged or behaves abnormally, stop using it and arrange professional advice; do not open or repair it yourself.
Fire and Rescue NSW’s EV guidance says not to charge a vehicle with suspected damage. For an EV incident, keep clear, call 000, tell the operator an EV is involved and follow their instructions.
Primary guidance checked 16 October 2026. Calculations use the explicit inputs above and do not establish vehicle performance or electrical suitability. Product features and the applicable installation requirements need confirmation for the actual model and property.
