About JuiceMyEV

Why this exists

Australian EV charging advice has a peculiar problem. The physics is simple — two formulas and one lookup — but almost nobody explains it, because the people publishing the advice mostly sell the hardware. So the advice trends predictably upward: bigger charger, three-phase upgrade, futureproofing.

Meanwhile the number that actually governs your driveway — your car's onboard AC charger rating — appears in no brochure, gets confused with the DC fast-charging figure, and can differ between two cars wearing the same badge.

The result is Australians paying thousands for capacity their car is physically incapable of using. Some of them end up with a three-phase charger that charges their car slower than the cheaper single-phase one would have.

Who writes this

JuiceMyEV is written and maintained by Paul. One person, not a newsroom.

I'm not an electrician, and I'm not going to pretend otherwise — which is precisely why everything here is sourced and the maths is shown rather than asserted. You shouldn't take my word for any of it, and the site is built so that you don't have to: every charging figure is computed in front of you and every car's spec links back to the manufacturer's own document.

Where I can't verify something, it says so. Where the sources disagree, it says that too. How we source and verify sets out the rules, including the widely-repeated Australian charging "facts" this site refuses to publish because nobody can produce a source for them.

What we do differently

• We show the maths. Every figure our calculator produces is computed live and every step is visible. Check it rather than trust it.
• We cite sources, and label what we couldn't verify. An honest "we don't know" beats a confident guess.
• We name the numbers we refuse to repeat. Several widely quoted Australian EV charging "facts" have no source at all. We list them on our methodology page rather than quietly pass them along.
• We tell you when the answer is "don't buy anything". Often it is.

Australian, specifically

Most EV charging content online is American or European, and much of it is quietly wrong here. American sites assume 120/240 V and NEC rules that don't apply. European sites assume three-phase is normal in housing — here it isn't. Even model specs differ: the Australian Toyota bZ4X has always been three-phase, while the North American car is single-phase, and that confusion is all over the internet.

So everything here is built around 230 V and 400 V nominal supply, AS/NZS 3000, Australian distribution network rules, cars actually sold here, and — where it exists — Australian measured data rather than lab claims.

What we're not

We're not electricians, and nothing here is electrical advice. We don't sell chargers, install anything, or take part in your purchase. An EV charger installation must be done by a licensed electrician who takes responsibility for compliance at your specific site.

We're also not infallible. Specs change, manufacturers revise things quietly, and prices move constantly. Everything carries a review date, and corrections are genuinely welcome.

How we're funded

Right now, we're not — the site carries no affiliate links and earns nothing. When that changes, we'll say so on the page where it applies, before you read the recommendation. The full commitment, including the conflicts we're aware of, is on our disclosure page.

Found an error? Own a car whose spec we've got wrong? Have a source for something we've marked unverified? We'd like to hear from you — owners routinely know things the brochures don't say, and measured data beats marketing every time.
