So be honest, do you / would you go out and unplug & move your EV when you hit your target charge percentage in the middle of the night? Is that what you're saying the etiquette is?
I probably wouldn't in this circumstance, first come first serve.
only problem with phevs is that they take a lot of time for very small amount of EV-only miles, since they charge very slowly quite often. For instance, Rav4 Prime had 3.3kw charger, now 6.6kw charger while most EVs have a minimum of 11kw on-board charger.
Plus you only gain 35 miles of charge, so who are you even kidding with public charging, it makes so little sense IMHO.
Over 14+hrs later the X is still plugged in. The 2 other Model Ys didn’t even get a chance to use the Tesla charger. I’m not sure about the speed of the Tesla charger that they’re using but the J1722 charger speed was sufficient.
On a slow charger, it will take at least 15 hours to charge that 100 kwh battery assuming he rolled in with it close to fully discharged.
I was plugged into such a slow charger at Niagara falls a couple of weeks ago. Went for a 70 km bike ride that took over 4.5 hours elapsed time and the car charged only 20% or 80 km....At that speed if the car was almost fully discharged (say I got there at 20%) it would have needed 18+ hours just to charge to 100% and my cars range is probably less than that X.

exactly... phev's are setup for local short commutes and at home charging typically with a regular outlet.

i think most people don't comprehend the math involved and the huge amount of electricity needed to fully charge a large ev battery. i roll my eyes when i read people say stuff like "why don't ev's have solar on the roof so they could run forever"? even a 400w solar panel means only .4kw (MAX) per hour, so an 80kwH battery so that would take 200 hours to charge it in ideal circumstances!

I think that's incorrect. For example, my solar at this time is producing 5.6kW
At peak I produce about 7.35kW. My brother in laws solar produces about 12kW at peak, he charges his car when he's producing peak power. If I were to turn my amp down, I could easily charge just using the sun's power. I produce at the height of summer about 55 or 56 kWh, so that would be the max. So it is conceivable to be able to charge using the sun, just not a full 81 kWh, which is the size of my Model Y's battery pack

Bit is talking about a solar panel on a car, not on your residence.
The Ocean has one of the larger solar roofs in the industry and will give the owner up to about 1,500 miles of additional range a year in a location like California with good weather, Fisker says.
"Under ideal conditions if you go in snail traffic on the way to work, bumper-to-bumper, you could get up to 2,000 miles a year. There comes a point where it is quite efficient, quite a lot of miles you can get free, total zero emission, so I think if you can afford it, it's a really cool feature."
"It's obviously still really expensive. We have spent a lot of time on developing it and making it work correctly. We put it in because I think it's a technology that, as we start improving it, maybe in the later stage in some years, we can double or triple the energy. Then suddenly you get to the point where you can do small trips without even using any other power than solar. We are not there yet."
Sunny climate = 1500 miles/year or ~5 full charges. Divide by 365 and you're at 4 miles a day
The point is even if it's no better than Level 1charging it's always there and always charging during daylight hours. These guys are working on a solar tonneau for truck beds - https://worksport.com/pages/solis-cor
they seem to think they can deliver 1.5kWh in about 2.5 hours.

1.5kwh is 5 mi. in my car. so if it were charging all day outside, say 7.5 hours, that would add 4.5kwh or 15mi. range. pretty useless.
this is also why solar roofs at ev charging stations are very limited. they can either charge maybe 1 car (with a huge array) or will need TONS and TONS of battery capacity ($$$$$) to capture all the sun when cars aren't charging.
The best panels today operate at ~23% efficiency. If the panels put on cars operated at 100% efficiency they would still only gain 16 miles per day on the Ocean or ~5.8kW

Depleted to full takes right under 2hrs. Mine has the 6.6kw charger and I always see 7.3-7.4kw according to my charger at home.
I drove/drive around in EV mode and always get over 35 miles. I did a highway only drive and got 42 miles (which is my roundtrip commute to work/home) and my longest in town EV drive was 55 miles with speeds under 55mph.
503 miles with 1.5 gallons remaining on this past weekend highway roadtrip in HV mode on 1 gas tank. I used EV mode moving around in town.
Is that what you're saying the etiquette is?
. I have 21 panels on my roof, and I can do about half a battery pack
