The only use for that is for people that cannot charge at home I would think. After having driven for 4 to 5 hours a 15 minute break is not an issue?

If you can charge while you sleep, you would typically have enough capacity to make it through a normal day?

Yes, there are probably exceptions but if you're not a commercial driver and drive >250 miles a day, that sucks....

I don’t know exactly, and I’m not an EV driver, but considering how many cars I see at supercharger stations, it seems to have a use case.

I’m guessing it’s an American thing too though, we can drive many more hours and no one is driving straight 4, let alone 5 hours going 75+ mph in an EV because no one is going to run their battery down to zero. On top of that Americans really don’t like taking long breaks on road trips because that only extends the trip that in a fuel vehicle can, well, could commonly be 6-20 hours driving in the past.

All the winning we are doing over here is quickly changing the mobility of American though. But that’s a whole different and interesting topic because it has major implications for America’s survival as a single entity that people overlook. America has held together to a large extent precisely because Americans could afford being mobile during the American century, i.e., the glue that kept the country together and made it feel like it belonged to us, an actual nation. That glue is breaking down for many reasons, one being expensive, impractical mobility.

It would be helpful for the current generation of smaller electic vehicles that are fine for daily use but would need to stop every 100 miles on a longer trip in winter.

Just got home from visiting family a couple of hours away in the highlands here. Battery is now at 40%, it'll take almost 2 days of charging at home to get it back to 100%. Hopefully I don't have another significant open highway drive to make in the next day or so.

Also our electricity rates fluctuate based on the underlying wholesale rate. It's going to be clear and sunny tomorrow at midday. Sure would be nice to be able to set my car to charge at midday when the price is single digits cents per kw, or maybe even negative. Instead I'll just have to drip it in with the higher rates at midnight-6am and know tomorrows cheap rates will average out to a much lower cost.

TLDR: definitely useful even for people who charge at home.

Man, people have wildly different lifestyles than what you presume, also some of us live in colder climates where official battery numbers become a joke. Those numbers would be unacceptable for me and my family for example, annoying and disrupting every single weekend. Suffice to say we own 2 ICE cars and no electric car is coming anytime soon, the overall costs and inconvenience are simply too high.
