No you don't. 20 minutes at a DCFC will get you to at least 80% for most EVs.
You need several hours to charge it at home, but it's gonna be at home for several hours anyways. With an L2 charger, you can go from 0-100% overnight.
L2 charging usually happens overnight, but larger capacity batteries won't fill if you don't plug in early enough.
It is 300 miles to my mom's house. Some electric cars could just make that in perfect conditions but give me a headwind or a cold day both of which happen once in a while and I can't make 300 miles on a charge and I will have to stop in the middle. At that point a fast charge is required. It is not acceptable to say I have to stop somewhere that I don't want to be for many hours to charge my car to get it the rest of the way. That is a trip where, if you have to make it, there isn't a better option. Flying would be even longer than driving by the time I get to the airport and rent a car on the far end, not to mention a lot more expensive.
At least in the U.S. it is very common for people to make a one or two thousand mile trip once a year for vacation. Particularly if you have a family, flying is not a reasonable cost and so you'll take those several days of driving to save money. Those road trips also let you stop someplace and see some weird small-town exhibit which is fun in its own way
I think the issue you're stuck on is driving an EV like an ICEV. When you're low on gas you stop, fill up, and continue. It's slightly different with an EV because you shouldn't fill up all the way on a stop. That takes so much more time because the batteries charge slower as they fill up. So if you want to get somewhere quicker you should actually be charging less at stops and stopping more often. I don't know about other cars but Tesla has a good route planner built in that does this for you and preconditions the battery while you travel to a fast charger, which is also important to reduce charge times.
In that 300 mile trip, there is a gas station every 10 miles. There is a level 3 charger every 100 miles. Which is to say, I certainly can make the trip in my electric car, but I'm I have to make sure I stop where there's a charger because unlike a gas car I can't say the gauge is getting low. I'll stop at the next exit. I have to say the gauge is at half per charge - I better stop at the next charger because I don't know if I can make the one after that.
Except most people stop for 15 minutes to refuel when they're on a road trip.
And to share my own anecdote, I've never once waited for a charger.
The great thing with an EV is you don’t have to stay there while it charges, so you can do those things in parallel.
You can do faster stops for the weekly fill-up, certainly. But in that case the comparable situation in the EV is zero minutes. The vast majority of owners will spend far fewer minutes on refueling for their EV in a given year even if the road trip stops really did take two or three times as long.
And those people are often bad at math or grossly undervalue their time.
Some people drive 10 minutes out of their way (20 min round trip) to save 5 cents/gallon. Even if you have a 20 gallon tank, that's only saving $1.00. I wouldn't take 20 minutes out of my day just to save $1, even 15 years ago when I was living paycheck-to-paycheck on $10/hr.
An EV that takes an extra 10-15 minutes over 300 miles seems like a reasonable alternative: there may be others.
They're definitely not. At least, certainly not any time within the next 10 years.
I've just done a thousand mile journey from UK to Norway in that car. It was not a big deal to charge on the way and would be less so in a newer car.
