Home charging explained

Last checked: 8 November 2026.

This page explains the electrical side: what your house can supply and what that means for charge times. For product choices, installers and tariffs, see the home charging guide.

Always ask a licensed electrician

Whether your home can take a given charger depends on your mains cable, switchboard and local network rules. Only a licensed electrician can assess that. Ausgrid states that all work inside a customer's property must be done by a licensed electrical contractor1.

Single-phase and three-phase

  • Single-phase is the common home supply. A 7 kW wallbox is the usual single-phase top end; RACV lists 7 kW single-phase at roughly 35 to 40 km of range per hour2.
  • Three-phase gives up to 22 kW on AC. RACV lists up to 22 kW three-phase at about 50 to 130 km of range per hour2.
  • Many homes have only single-phase. We did not find an authoritative Australian source for the share of homes with three-phase, so none is quoted.

The kW figures follow from the current rating. A 32 A single-phase circuit at a nominal 230 V is about 7.4 kW; a 32 A three-phase circuit is about 22 kW; a 16 A three-phase circuit is about 11 kW (our arithmetic; nominal supply voltages are 230 V single-phase and 400 V three-phase).

A car only charges as fast as the slower of the car and the wallbox. See which grade takes what in the home charging guide: the 7X takes up to 22 kW AC on all grades3, the X RWD and 009 FWD are listed at 11 kW and the X AWD at 22 kW45.

From the street to your car: single-phase vs three-phase Power reaches a home charger through the street network (DNSP), the service cable, the meter, the switchboard (main switch, RCD and EV circuit breaker), the wallbox (EVSE) and the car's onboard charger. Single-phase is one live plus neutral: a 32 A circuit gives about 7.4 kW at most. Three-phase is three lives plus neutral: about 11 kW on a 16 A circuit and about 22 kW on 32 A. Figures are nominal, calculated at 230 V and 400 V. A licensed electrician checks the mains cable and board, the network may need notification or approval, and the car's own limit still applies: X RWD 11 kW, 7X 22 kW AC. HOME CHARGING: YOUR SUPPLY Single-phase tops out at about 7.4 kW. Three-phase lifts the ceiling to 22 kW. The car's own AC limit still applies.

Real charge times

Hours from empty to full, ideal case, at the wallbox's rated power (energy divided by power, before charging losses). The car's own AC limit caps the speed, shown as "limited".

Pack (grade) 10 A portable 7 kW 11 kW 22 kW
61 kWh (X RWD) 26.5 h 8.7 h 5.5 h limited to 11 kW
66 kWh (X AWD) 28.7 h 9.4 h 6.0 h 3.0 h
75 kWh (7X RWD) 32.6 h 10.7 h 6.8 h 3.4 h
100 kWh (7X Long Range, AWD) 43.5 h 14.3 h 9.1 h 4.5 h
116 kWh (009 FWD) 50.4 h 16.6 h 10.5 h limited to 11 kW

Pack sizes come from CarExpert435; the hours are our arithmetic. The 2.3 kW portable figure is 230 V times 10 A, as used in the home charging guide. RACV puts portable chargers at about 1.4 to 2.8 kW2. In daily life you rarely charge from empty: a typical 20% to 80% top-up takes 60% of those hours. Real sessions run longer than the ideal, and we found no sourced loss figure.

Overnight is usually enough

Ten hours on a 7 kW wallbox adds about 70 kWh, before losses. For most daily driving that covers it.

What it costs

Quotes vary widely

We found no authoritative price guide. The ranges below come from installers and comparison sites, and mid-2026 figures. Get at least two quotes.

  • Typical installed single-phase 7 kW jobs are quoted from about $1,000 to $1,500 (EVSE Australia)6, $1,200 to $2,299 (Solar X Energy)7 and $1,500 to $3,500 depending on complexity (e-Green Electrical)8.
  • The main cost driver is distance from the switchboard and whether the board needs work. Older homes built before the mid-2000s often need board work before a 32 A circuit can be added7.
  • We found no sourced three-phase price.
  • Zeekr offers: the MY27 7X launch offer for orders from 1 November to 31 December 2026 includes a 7 kW wallbox, supply only; installation by a licensed electrician is at your cost9.

Network approval, at a high level

Your electricity network (the distributor, or DNSP: Ausgrid, Endeavour, Energex, Ergon and so on) has rules for how big a charger you can connect. They differ by network and they are changing. In general:

  • Your electrician checks your supply and tells you whether the network must be notified or must approve the work. Ausgrid says it requires approval where the electrician identifies a need to upgrade the supply, and it may ask to be notified before installation so it can assess grid impact1.
  • One industry article gives thresholds of 20 A single-phase and 40 A three-phase for notification, but says the figures were not checked against the primary guideline10. We have not confirmed them. Treat them as not confirmed.
  • Queensland (Energex and Ergon) has had extra rules for single-phase chargers, including network devices or limits. Older Energex material says a dedicated 22 kW three-phase charger switched across all phases can be connected without those device options11. One report says the limit on single-phase 32 A chargers without a network device was withdrawn from 1 October 202612. That is a single news source that does not reproduce the manual, so check the current Queensland Electricity Connection Manual (QECM) before relying on it.
Getting a home charger connected Five steps to connect a home charger: 1 choose the charger size from the car's AC limit and your supply; 2 a licensed electrician inspects the mains, board and phases; 3 find out whether the network needs notification or approval, which varies by DNSP, and either notify only or apply and wait; 4 install and test; 5 charge. Rules differ by network and change, so check your DNSP. HOME CHARGING: GETTING CONNECTED Check with the network first. Your electrician tells you whether the network must be notified or must approve the work. 1 Choose charger size Car AC limit, your supply 2 Licensed electrician inspects Mains, board and phases 3 Does the network need notification or approval? Varies by DNSP Notify only Apply and wait 4 Install and test 5 Charge Rules differ by network and change. Check your DNSP. Queensland has had specific single-phase rules, reported changed 1 Oct 2026 (unconfirmed).
The usual order of steps. Rules differ by network, so your electrician leads.
