I'll throw my hat in the ring of rage:

PHEVs are (largely) for consumers who don't understand how EVs work (but think they do) and are too scared of having to sit in their car and charge for an hour anytime they leave the town perimeter.

In reality with most EVs, you can drive 500 miles with one 30 minute charge. That's 7 hours of driving at 65mph, and one 30 minute charge. I know everyone claims to be a psychopath driver who never stops on a road trip for more than 5 minutes every 7 hours when they learn this, but the reality is you don't even notice the charging stop. Unlike gas pumps, it's the norm to leave your car on the charger while you go do something else (eat, sight see, shop, w/e).

It's only really trips that are >500 miles where this starts to become apparent. Or on trips through remote areas. Or having no idea how EVs work, driving till you're almost empty, then deciding it's time to get off the highway and find a charger.

The consumer segment that actually needs PHEVs is incredibly small, but the segment that thinks they need them is huge, hence the market.

I've driven from Portland to Santa Clara and back twice in my EV. The first time, I actually planned my charging stops and made a spreadsheet of expected charging times and actual charging times.

The first time I did the trip, for each 665 mile leg, I spent about 75 minutes charging, which certainly gives more charging time per mile than your estimate, but it's also because I wanted to arrive at my destination with 80%, and also I gave ABetterRoutePlanner pessimistic numbers regarding my range, and as a result, was charging at higher SoC's than planned. Still though, even with the poor planning, I spent literally zero minutes sitting in the car waiting for it to charge.

A year and a half ago, I drove from Portland to San Diego and back. 2,200 miles. I had zero complaints about charging times.

I did have some minor range anxiety last year driving around Yellowstone, since I'd only have access to a charger at the start and end of my day. Just had to remind myself that I wasn't really driving THAT far throughout the day, and that the driving I WAS doing was going to be relatively slow.

I'm just gonna call bullshit on that one. https://ev-database.org/cheatsheet/range-electric-car looks like it's got a bunch of recent vehicles, and pegs average range at 390km or 242mi. The _highest_ range there is 720km or 450mi, and a 300KW charge runs it 10-80% (+500km range, not miles) in a half hour.

If you _don't_ have the absolute best range + infrastructure to support the charge at that rate: I've got a 2020 Kia Soul w/ 64kWh battery and lines up with the 390km range rating. Did a road trip last year. My charger caps out at 73kW or so on a DC charge, and a charge at that rate (40%-80%) gave me ~150km in a half hour. 10-80% is ~220-250km and takes an hour.

Now, I did the road trip with two kids and a dog, so an hour's potty/walk break every 2-2.5h driving worked out for us, but I don't think that's entirely generalizable. I do also agree that unless we're road-tripping, it's a nonissue. We put a level 2 charger in the garage, and plug in overnight once or twice a week and no range stress at all.

I think they assumed a Tesla Model 3 or Hyundai Ioniq that has 300 miles of range. You leave home with 80% or 100% charge. Stop at a supercharger for a half hour when you have 50 miles left, which will get you back up to 80% battery.
Call it a midrange Model 3 (RWD), ~275mi range from full, drive 250mi, 25 mins to 220mi range again?

OK that roughly lines up - the Model Y doesn't quite get there (on expected range) and it's apparently 40% of the market, but it's also pretty close.

Assume 300 mi range and 200kW charging

Leave home full charge -> drive 275 miles -> charge 30 min to 80% -> drive 225mi -> arrive with ~10%
