10 to 90 is indeed slow (not as slow anymore as that article). 10 to 80 is about 40 minutes. So not quite as bad as you're saying.

10 to 80 leaves me 70% effective capacity, so that's 0.7 * ~400 = ~280mi/charge. This would mean on my 575mi drive I'd spend 3 * 40min = 2hr charging. So it'll take me 11hr to do a 9hr drive. Let's say I was towing. That would give me ~180mi/charge. On the 575mi trip I'll have to charge 4 times, so 2hr40min. So that's actually worse than I calculated before in both cases. EDIT: it seems to me this technology isn't ready for production yet. Or, at least, it's best suited for subcompact vehicles that don't get loaded heavily. EDIT2: I get it, though. If I lived in a city or a suburb and used my car exclusively as a grocery getter + commuting rig, it might make sense to run an EV--if there was a good one available at a reasonable price. But that's the other thing. They're all expensive, unmaintainable, and packed full of useless infotainment garbage and a whole bunch of plastic--just like everything else built this century. So really what's the point of using electrons from the grid instead of gasoline from the pump if I have to get a new car every 5-10yr? Instead, I'll maintain my (currently) 25-30y.o. vehicles s.t. they'll last a further 20 years thereby having prevented something like 10 cars from ever having to be built in the first place. And I own them outright, so no car payment.

  > Let's say I was towing. That would give me ~180mi/charge. On the 575mi trip I'll have to charge 4 times, so 2hr40min. You wouldn't start full? Using your numbers, 250*.9 + 180 + 180 makes the trip in two charges. Stopping a couple of times for meals makes it take no net increase in time. edit: It definitely doesn't work for everyone and every use case, but it's much better than you calculate. The EV road trips I've taken have been slightly inconvenient but the day to day convenience of at home charging makes up for it. Also I don't understand why you're continuing to edit your message long after I replied.

  > You wouldn't start full? Using your numbers, 250*.9 + 180 + 180 makes the trip in two charges. Sorry, you're quite right. So towing it'll be 2hr of charging for 9hr of driving, empty it'll be 80min for 9hr. I don't really buy the meals argument, though... I can't recall when I've ever stopped for a meal while driving somewhere. Even on long road trips (like 4k+ mi) I prefer not to eat whole meals during the day as I find they make me less alert and sleepy, especially given the lack of physical activity driving entails. That's not to say it would be impossible, or bad even, to take a few half hour breaks during a day's drive. I hope some day a car manufacturer decides to make a simple, decent, 25+yr vehicle again. No plastic, repairable, maintainable. I'd love to buy one.
