I'm off for three days and you guys start talking about EV charging. Literally doing 1200km in two days in a 66kW Hyundai. A few points to add to the discussion:

1) you charge where you park. You top up in quick breaks when you need to go further. Nobody wants to fastcharge, so we expect it to become a much smaller part of driving than gas stations are now. Over here we expect just 13% of all EV charging to be at (highway) fast chargers. Imagine if you could fill up your car with water. Would you really opt to fill it up at a random industrial parking lot you could also drop a hose in it on your own driving lane and at work for half the price? How about your employer realizing they could make money by offering you free charging when you allow them to use your car as a battery storage? Opportunity charging, which is that you charge when your car is standing still anyway, is the inevitable way forward.

2) The US is dearly lacking in both fast and destination chargers. Range anxiety disappears once those two are remotely reliable - I know this from first hand experience and from a bunch of studies done on the Dutch charging station network, which happens to leave every other country in the dust. As soon as it's a common sight for there to be a charger in a parking lot, people stop complaining. Because I already have the luxury of a dense and reliable network of destination and fast chargers, I almost never have to worry, and I also almost never fastcharge. Colleague of mine has a charger at home and at work and he's never even used a fastcharger. Because if you leave full and can charge at your destination, that's two charging stops eliminated. So a <car range> mile trip both ways is made possible by just one charger at my destination, that happens to also be a decent way to make money for businesses with a large energy connection. Tesla drivers love their Superchargers, but normal people will avoid them if they can. And if you do need them - for most people, as soon as your EV can do 100+ kW of fast charging, which is "most new models and probably whatever first model upper class people will buy", nobody minds the stops because you'll be ready to drive another 150-200 miles right when you're done taking a piss or grabbing a coffee. Especially when you factor in that charging is cheaper per mile than gas.

3) What will drive the change in chargers? Well, the business case for EV destination chargers is decent. The case for rapid chargers is VERY good as soon as you hit a certain level of daily users. There is less overhead and less insurance than a gas station. It never needs refills, and you can basically just plop one down and wait for your investment to pay off. Even a small station can draw traffic, or can boost sales. The number of rapid chargers that aren't Tesla has doubled in less than eighteen months over here. We fully expect every supermarket, DIY store, McDonalds and Starbucks (any place that you will park at for more than 20 minutes and that owns the land it's on) to follow suit.

4) Smart charging capabilities have been made mandatory on all public slow charging stations here. The collective energy use of EVs will be a hit on the grid, but it's in the form of "small spikes in many places", which is something that grids are in theory perfectly capable of handling if dimensioned correctly. The real problem that will fick things up are heavy vehicles. They consume a factor 10-15 more energy than cars per km and require near 1MW chargers if you want to top them up along the way. The energy use of industrial zones can easily increase by TWh's if adopted widely, which is not the case of personal vehicles. And the TCO, which is nearly always the main driver of any EV adoption rate, however is good enough that the trucks will be here before the infrastructure is upgraded.

5) I still dream of a V2G system of energy brokerage whereby we can delay daily power use with cars and home batteries. The realities are complicated, and the rise of EVs seems to be going just a bit too fast for V2G to catch up. My city is one of the first to realize what you guys are theorizing about.

But it's the result of one incredibly entrepreneurial dude who's been at this problem for 8 years. Wider adoption... I don't know. I hope so.
