This is impractical in so many ways. First, you don't charge to 60% you charge to 80%. Second, having driven many thousands of miles on EV trips, I can tell you that you can't successfully schedule your stops on a clock. Impossible to do.

There is ONE charging company that I know of that said they allowed reservations, EVgo, and I think that's been turned off.
I agree, also with multiple long distance (multi-day+) Mach E trips under our tires by now.

IMHO in 3 - 4 years things will be very different, even in the current charging desert of West Virginia.

Businesses have to be able to get off the ground to begin with. It's the chicken-and-egg problem: If they can't scale up, they can't make money. If they can't make money, they can't scale up. There are lots of incentives out there to get DCFC prices lower for consumers at the beginning of this transition, but over time, those incentives are going to slowly dry up, letting the companies sink or swim on their own.

This isn't a conspiracy; it's well-known that DCFC takes a lot of financial investment. Demand charges are very real, and very high - something everyone is actively working to reduce. It's also why most networks are switching to per-station real time pricing.

Lower cost of fueling shouldn't be the sole reason for EV transitions, but I suspect I'm actively veering into dangerous territory there ;)
Demand charges do not have a negative effect unless the commercial load has a poor load factor. If the commercial load operates at peak load for about 75% of the day then the demand charge are a wash. If they have a greater load factor than 75% their electricity actually becomes cheaper. The utility has to build facilities large enough to meet the commercial loads peak. They have to recover that through sales. They guarantee cost recovery through demand charges. Otherwise the costs are passed on to others. Rate making is a cost causer cost payer exercise. Just a personal pet peeve because many complain about demand charges without understanding why they exist and for a normal consistent electric load they do not increase costs.

Currently a person is allowed to stay at most chargers as long as they want. On non-holiday weekends reservations are not needed. They are needs for the busiest holiday travel times. This probably will not be true after 2024. Ferries have reservatins. Trains have reservations. Planes and motels have reservations. Naysaying is not a reason against them.

I went to a sporting goods store today and there was a BK next door. There were a dozen V3 chargers there under covers. Not sure if they had Magic Docks or not since they were covered up. ?‍♂?

Sorry, are you saying most DCFC sites aren't hit by demand charges?

No, just that demand charges are not expensive as long as there is a high load factor. Basically just because it has a demand charge does not make the electric charge high. If you look at the overall rate it will have the demand that looks high cost but then the per kWh charge is low. As a matter of fact if the load factor was above 75% (or there about as it depends on rate making) the electric cost will be less than residential. Then the only additional cost would be the charger and profit. Of course the issue is very few DCFC have a load factor approaching 75% but the alternative would be to pass on the cost to others and that is not fair.

Well, yes, DCFC is always going to be inherently worse than gas refueling just by it's very nature. It takes 10x longer than a gas refuel, which is way worse right there. It also means bottlenecks are 10x more likely because it takes so long for the people before you to get out of the way when many happen to arrive around the same time. And the cost equation for installing more chargers is terrible vs gas because 90% of charging takes place at home, thus 90% of the revenue potential that gas has simple doesn't exist for DCFC. That means investing in a ton of redundancy doesn't make business sense.

So if the comparison is to the quickness and capacity of gas refueling, you'll always be disappointed. That's never gonna be matched, even on Tesla's better network. The entire model is at an inherent disadvantage. If you want gas standards for quick and plentiful refueling, you'd need to stick with gas.

Of course, what arguably makes the worse DCFC refueling experience worth it is that home L2 charging is so much better than gas. Better 90% of the time + worse 10% of the time is considered a net plus to many.
Yep, which is why I think we act like early adopters and make excuses for a crappy experience because the technology is so cool. I do it also.

Refueling at home is 100x better than getting gas from a gas station. If you never need to get a public charge, a BEV is by far the best experience. That is why my next BEV needs to have a lot more range.

Here is mine charging with MagicDock, 125kW was the highest I seen,
That's the max for a Magic Dock charging a Mach-E. The MD's are only rated for 350A max. The Mach-E battery pack voltage is roughly 355V. 350A * 355V = 124kW.

Lets hope the Ford adapters will be rated for more.

Almost all of the DCFC charging curve is 124 kW or lower. Mostly lower. So the total impact is very minimal. If the MME could keep a sustained charge rate of above 124 kW for 20 minutes I would be concerned. It can't.

I am so ready to buy my adapter!

I rarely charge above 60% when road tripping. Also try to stay under 20 minutes at each stop, unless we are eating. People that charge to 80% or more at each stop are the ones causing the lines.

I guess we will just disagree. Using 40% (60 - 20) of my battery, or 36kW, means stopping every ~100 miles, is inefficient and too often for me. More likely, you won't find a charger every 100 miles on many routes. Every 150 miles is much more likely. Also, every stop takes at least 5 minutes on each end. Your 20 minute stops are 30. My 30 minute stops are 40.

I can go 150 miles using 10-60% on my CR1, at 70-75mph. My Rivian does the same. I am typically last in first out at chargers. On my latest trip of 750 miles, I did it with 4 stops, averaging 25 minutes. We ate at 2 of those stops. I skipped many chargers.

On one trip I took this summer, I needed to charge to 100% because my next stop didn't have any chargers and I planned to be driving around quite a bit. It took an hour.
