Charging stations are extremely scalable, though. Tesla has one supercharger in California with 98 charging bays, and plans for another with 200 bays. You’ve never seen a gas station with that many fuel pumps because it would be extremely difficult to install the tanks and fuel plumbing and fire suppression systems to make it work. With electric charging you just need a parking lot.

The throughput of a charger is a lot lot lower. A single pump can maybe serve 20 cars an hour if it’s got a credit card reader. Most petrol stations in the UK have this and maybe 4-12 pumps depending on size. So just ball parking, if the average needed duration to charge is 10 mins on a supercharger, you need 4x more chargers than you would pumps for an equivalent.

The obvious difference is that you can’t pump your car at home, and by installing chargers in ordinary car parks you can mitigate the need the specific infrastructure of petrol stations, but the number of total chargers needed is still high, they are just not in the same places.

But you don't need that many pumps, because it takes 5 minutes to fill up the gas and pay... and then drive a 1000 more kilometers. You don't have to stay there for 1hour+ and then repeat the same after a few hundred kilometers.

Pretty much no EVs on the market in North America take an hour or more to charge enough for a few hundred km.

On the road trips I've gone on with my EV the average charge time I had was like 15 minutes. The longest was 22 minutes. I sometimes charged a little longer than as it took some time getting the kids through the bathroom and get a snack.

And my EV kind of sucks for road trips. Smaller battery, only 400V instead of 800V, and a less efficient motor setup compared to other EVs on the market.

I just did the math, and it's even worse...

VW id.3 are one of the most popular electic vehicles here.. They don't need an hour on fast charger, but still...

I took the data from here: https://ev-database.org/car/1202/Volkswagen-ID3-Pro

> Charge Time (35->280 km) 31 min

So, for ~250km of driving, you chrage it four half an hour (let's say everything is ideal, no AC needed, no stopping in traffic with ac running)... for a drive from eg Frankfurt to split (~1200km) and then back, this means 9 charges (assuming you did the first charge at home, which is far from a common thing in frankfurt with a lot of apartment buildings and not a lot of chargers there). For a normal diesel car, that would be 2 refills (assuming you started with a full tank... and you'll still haeve half a tank left over).

So, 9 charges means using the charging stations for 279 minutes, a bit over 4 and a half hours if done ideally. Refilling a diesel would take 10 minutes. So to serve an equivalent number of tourists here in transit (since our gas is cheaper outside of highways, and locals fill their cars there), we'd need 28x more charging stations compared to gas/diesel pumps. Also, even with gas pummps, during peak times (weekends all summer), you sometimes have to wait for 3-4 cars infront of you to refill, so even that is not enough for peak usage.

So, for an average german tourist going to croatia for a vacation (and there's a lot of them.. a lot!), the electric car is useless until we build A LOT more charging stations, 30x more than our curret gas ones, and add 4.5 hours of drive time.

Sure, living in a house (charge at home) and commute to work and back within the range of the vehicle... that's great. But for road trips, we're not really there yet.

I deleted my earlier comment, I didn't realize you were saying 1,200km there and back. So nine charges to go 2,400km does sound a bit realistic.

But you're saying 4 and a half hours to charge to go 2,400km is worse than the above poster who said 1+ hour to go like 200-300km. 4.5 hours of charging to go 2,400km is ~533km/h effectively, assuming starting with a good state of charge.

But you're also ignoring the fact nobody doing that route would be driving 1,200km and then immediately turning around and driving back home. They're probably going to stop at some point along that 24+ hour journey, right? Probably going to spend the night somewhere, probably going to get food to eat somewhere, right? I imagine most people need to use the bathroom at least once every 24+ hours? And they're probably driving that distance to actually visit someplace, so they're likely going to stay there at least a few hours if they're willing to drive over a dozen hours each way right? So some of those charging stops are realistically only a few minute wait, as you're just talking about the time to plug in to the charger near a restaurant, or plug in to the charger near your destination, etc.

Do drivers in Frankfurt really get in their car and drive 24+ hours round-trip only stopping to get gas a couple of times? Do people in Frankfurt not need to sleep, eat, or pee? Is driving 24 hours non-stop round trip an ideal German vacation?

And then to top it all off, the ID.3 isn't the best road trip EV. There are many other models that will charge faster. If you're the kind of person making non-stop 2,400mi road trips every few months you could pick a different EV that has better charging speeds.

Pick a Kia EV6 Long Range and you'll get an average of nearly 200kW charging speeds doing a 10-80% charge. The ID.3 Pro in your link only gets about 82kW average charging speed for a 10-80% charge. (1070 km/h vs 470 km/h). You'll end up doing the trip in significantly less charging time.

No, those drivers drive 10, 12 hours from frankfurt to croatia, then park in a place like this: https://maps.app.goo.gl/hRNCgPUhGEHayXex6 or this: https://maps.app.goo.gl/mTg4SpaNrcsi1hiv5 https://maps.app.goo.gl/dWEqaBQNVbMtC26f8 or https://maps.app.goo.gl/w4Ywf5cMzU1e4dSf8 etc. No charging station anywhere. I live much closer to that (only ~500km), and park between cars with german and czech licence plates in parking "lots" just like these every year.

I also live in a transit country for them, so I have to actively try to avoid them every summer: https://www.rtvslo.si/slovenija/zastoj-pred-predorom-karavan... most of them have german plates (this is on the way back in a 15km long traffic jam before a tunnel, and our police closed the exits so they can't leave and use the local roads.

This is the charging station before that 15km traffic jam: https://maps.app.goo.gl/xBrxbccqVg7mSw3D8 ...so, either wait here in line, or risk it for a few hours... will you use the AC, or not? :) It's not much better in austria, and even worse in croatia.

Yeah I’m baffled by the GP poster. 15 min is standard. 25 or 30 in rare circumstances or when you want to sit down for food. And this is using today’s battery chemistries, while even faster charging is already coming from solid state and sodium batteries. Naively if we assume that a gas car can move in and out in 5 minutes, you need 3-5x as many charging bays to maintain similar throughput, and those numbers are already deployed in some stations. I also think the poster seriously underestimates the cost of building, maintaining and decommissioning fueling infrastructure. Gas stations are not cheap or scalable in the same way that charging stations are.
