01
Vehicle & charger
We consider the charging capability of the vehicle and the EVSE you want to install so the electrical work matches what the equipment can actually use.
EV Charging · Homes & Businesses
Install the charger around the property — not the other way around.
AESS installs AC EV chargers for homes and commercial properties across Toowoomba and surrounding regions. Before we run the cable, we look at the switchboard, existing electrical load, supply capacity, charger location and what else the property may need in the future.
Start with the site
The right charger depends on more than the car.
Vehicle capability matters, but so does the building it plugs into. A charger that looks perfect on a product page may be unnecessary, undersized or impractical once the switchboard, cable route and available electrical capacity are considered.
02
Switchboard & supply
The existing protection, available board space, supply arrangement and maximum demand all influence the appropriate installation.
03
Parking & cable route
Charger location, cable distance, construction, weather exposure and the way vehicles actually park can materially change the job.
Electrical capacity first
An EV charger is a meaningful new electrical load.
Even when the charger itself is straightforward, it contributes to the installation's total load. AESS assesses maximum demand and the relevant protection and supply arrangement before committing to the final charging circuit.

Existing household or business load
Air conditioning, electric hot water, cooking, machinery and other significant loads all form part of the picture.

Switchboard condition and space
The board must have an appropriate way to accommodate the new circuit and protection.

Incoming supply and mains
Where capacity is tight, the consumer mains or broader supply arrangement may need to be considered rather than looking only at the charger circuit.

Future loads
A second EV, more air conditioning, a pool, induction cooking or workshop equipment can influence how much headroom is worth allowing now.

Charging rate
Fastest available is not automatically the best installation.
For many owners, overnight home charging means the car has hours available to recover the energy used during the day. The sensible charger size depends on kilometres travelled, vehicle capability, available supply and how quickly you genuinely need the battery replenished.

Questions worth answering first
How far do you actually drive?A car doing modest daily kilometres may not need the maximum charging rate its onboard charger supports.
How long is the vehicle normally parked?Eight or ten hours at home overnight is a very different use case from a commercial vehicle needing a short turnaround.
What can the vehicle accept?Installing a higher-rated AC charger does not make the car accept AC power faster than its onboard charging hardware allows.
What can the property comfortably support?The charger should fit the electrical installation, not force unnecessary upstream work unless the extra capacity has genuine value.
Home & commercial charging
One EV at home and ten vehicles at work are different electrical problems.
AESS can approach residential and commercial charging around the actual use case rather than treating every installation as the same wall-mounted charger.
A
Home charging
Dedicated AC charging for a garage, carport or driveway, with the existing household load and future electrical plans considered before installation.
B
Workplace charging
Charging for staff, customers or business vehicles where electrical capacity, access, operating hours and future expansion all matter.
C
Fleet planning
Multiple vehicles can turn charging into a distribution and load-management project rather than a collection of unrelated single chargers.
Solar-aware charging
Already making solar during the day?
Some EV chargers and energy-management systems can vary charging to make better use of available solar generation. The practical options depend on the charger, solar equipment, metering arrangement and when the vehicle is actually parked at the property.
Worth considering — not worth overselling.
If the car is away from home every weekday while the solar is producing, a sophisticated solar-diversion feature may have less value than it first appears. If the vehicle is regularly parked during generation hours, it can be much more useful.
AESS can look at the electrical side and help determine whether the proposed charging setup makes sense for the site.
Plan past the first vehicle
The first charger is the cheapest time to think about the second one.
You do not have to install future chargers now. But cable routes, switchboard space, distribution and capacity can be planned so the next vehicle does not require starting the electrical design again from scratch.
Second family EVAllowing for another vehicle can affect charger location, board space and how the available load is shared.
Business fleetTwo chargers becoming six is easier when distribution and capacity were considered before the first two went in.
Switchboard upgradeIf the existing board is already crowded or ageing, the EV project may be a sensible trigger to modernise it properly.
Three-phase planningWhere a property already has three-phase supply, or genuinely needs a broader supply upgrade, EV charging can form part of that larger capacity conversation.
AESS approach
Car. Charger. Property. Then cable.
1
Understand the use case
Vehicle, daily kilometres, parking location, desired charging speed and likely future charging needs.
2
Assess the electrical installation
Review the switchboard, supply, relevant existing loads and the proposed cable route.
3
Define the installation
Confirm charger location, circuit and protection requirements, any management features and any upstream electrical work required.
4
Install, test & certify
Complete the electrical installation, test the work and issue the required electrical compliance documentation.

Common questions
EV charging FAQs.
Can I just plug my EV into a normal power point?
Some vehicles can charge from a suitable socket using manufacturer-approved portable charging equipment, but dedicated AC EV charging is generally more practical for regular charging. The appropriate setup depends on the vehicle, charging needs and electrical installation.
Do I need three-phase power for an EV charger?
No. Many home charging installations use single-phase supply. Three-phase charging may be useful where the vehicle supports it and the property has a suitable three-phase supply and capacity.
Does a 32A single-phase charger still need load management in Queensland?
From 1 October 2026, the former QECM requirement for active management of a single-phase 32A EV charger under clause 8.14.4(b) was withdrawn. The installation maximum demand must still be recalculated and any required protection or supply changes addressed. Load management can still be chosen where it is useful for the site.
Will I need a new switchboard?
Not automatically. AESS assesses the existing switchboard, available space, protection and electrical capacity first. Some sites only need the new charger circuit; others benefit from a broader upgrade.
Can the charger use my solar?
Some charger and energy-management products support solar-aware charging. Whether that feature provides real value depends on the existing solar system, charger compatibility, metering and when the vehicle is parked at home.
Can AESS install a charger I have already purchased?
Potentially, yes. We would first need the make and model details and to confirm the equipment is suitable for the intended installation and Australian requirements.
Current network information on this page reflects Energy Queensland's September 2026 contractor alert withdrawing QECM clause 8.14.4(b) from 1 October 2026. Electrical installation work in Queensland must be performed under the appropriate electrical licensing arrangements.
EV charger enquiry
Send us the car, charger and property details.
Tell us the vehicle, the charger you are considering, where the car parks and whether the property is single or three phase if you know. We can work out the electrical side from there.
