At some point later I got around to playing with DC fast charging ... That market still has a long way to go as far as sorting out its business model, as billing based on time vs energy is completely unfair ... An excuse that's offered less and less often is that pricing by kilowatt-hours delivered is prohibited in some states by utility regulatory rules. I didn't know they were billing for DC charging in the US base…

I've never paid by the minute. Tesla Superchargers often deliver less energy per minute when they're busy (sometimes much less!) and it would be frustrating if they charged per-minute. Other systems I've seen (Chargepoint) also seem to be energy-based. The Supercharger network is well done. It's a shame that they took this long to open up to other car models because they really do get a lot of things right.

Careful. Some superchargers will now charge you extra per minute as soon as you cross 80% capacity (regardless of your charge limit).

My understanding is that some US states have regulations against selling power by the kWh unless you are a registered power utility. This is an old regulation meant to be about landlords marking up electric rates to tenants etc.

Most states have updated their laws to account for EV charging providers, and in those states we pay per kWh.

In some states, like Georgia, you are considered an electric company if you bill in kWhs. So some DCFC companies simply billed in the time equivalent. $0.30/min-$0.50/min.

I've seen videos of that car... don't they only have like 40 miles of range, and the range extender only holds like 5 gallons of fuel?

You don't want the range extender - it makes it fiddly and potentially unreliable. As for the range, I'm getting about 110 miles of range. It depends how you drive. This is the 94Ah battery, the later models had more range.

Range extender was definitely a requirement when I got mine in ‘19. But that’s because I did not have reliable charging available in the area.

It also came in handy for a bad road trip (charging stations more than my range apart, so I couldn’t otherwise get there from here, but hold state of charge kept it up at 75% with frequent gas stops)

No need to go further than dead center EU to see chargers where the cost has a time component, and an energy component, and even a (small) one time fee. Sometimes the charger is inside a paid parking, there that comes on top. These aren't shady operators either either, just the way they saw fit to prevent abuse and make more money. Some have reasonable limits to prevent abuse [0], others just charge the customer as m…

Is abuse here just parking in the charger and leaving for a few hours, assumingly skipping any parking fee if you're only paying for kWh?

Abuse means leaving your car parked while it is not actively charging.

Fine to leave for a few hours if your car needs a few hours to charge fully.

Not fine to leave for a few hours if your car was 15 minutes from full.

Later on ( https://techno-fandom.org/~hobbit/cars/ev/dcfc/app-problem.h... ) he talks about the app problem, and I believe the UK and possibly the EU are mandating that chargers must support contactless payment, so you can just do it with your regular bank card.

Glad it worked out for you. I am in South Africa so there still aren't many charging stations but we're getting there. Most people charge from their houses though and that's what I do as well. With solar it's practically free to drive around town, school runs etc.

Does this also apply to non-Teslas? I'm guessing there's a bit of two-way communication from car to charger, for authentication/billing purposes but also for congestion fees like charging beyond 80%. Does the app notify you to take your car off the charger?

I understand the reasoning but sympathize with the luddites who shun all this technology. Imagine going on a road trip with your EV, stopping for a bite to eat and refresh while putting your car on the charger. Maybe there was a long line or you needed a long bathroom stop, so your car sits at the charger "too long" and you get a nice penalty.

I know Electrify America used to, but in recent years, I haven't come across any time-based chargers (but I haven't used a charger outside of Texas since 2022, so may be an issue in only certain states, as other comments have alluded to)
