Sources
Everything on this site comes from one of two places: an official Australian source listed below, or an assumption we state openly and let you change. No source is a blog post or a marketing page.
All sources below were checked on 2026-10-04. Where a fact could change — tariffs in particular — the page says so rather than freezing a number.
How to charge your electric vehicle
- A fixed or hard-wired charger must be installed by a licensed electrician.
- Extension leads and power boards must not be used for EV charging.
- A portable charger in an existing compliant socket generally needs no installation, but the socket and circuit should still be checked.

Charging options for houses and strata buildings
- A 7–22 kW charger adds substantial continuous load, so maximum demand and switchboard capacity must be assessed.
- An upgrade or alteration to the supply may require an authorised Accredited Service Provider, depending on state and work involved.
- Apartments and strata may require load management and owners-corporation approval.
Understanding your energy bill
- A time-of-use tariff charges different rates by period: peak, shoulder and off-peak.
- A daily supply charge applies regardless of how much electricity you use, so it does not change when you charge more.

Electricity pricing plans and tariffs
- Time-of-use rates and their windows differ by distribution area, retailer and plan, so no single Australian rate is quoted on this site.
- Time-of-use pricing generally requires a smart or interval meter.

Electricity safety in the home
- Electrical work in NSW requires a Certificate of Compliance Electrical Work (CCEW) from the licensed electrician.

Figures this site assumes rather than cites
Charging losses and the share of rated power a car actually accepts are planning assumptions, not published official figures, because they vary by vehicle, temperature and state of charge. The calculator defaults to 10% loss and 85% of rated power and shows you both on screen, so you can change them or substitute a figure from your own car.
Electricity prices are never quoted as an Australian average here. Retail prices differ by distribution area, retailer and plan, and change. Enter the rate from your own bill.
