Talk about EV chargers in the US, I just browsed to "plugshare.com" to see its latest map. I then zoomed in to certain areas, and panned around to see the distribution of the chargers.
There are many chargers in CA. But in other Western states, there are stretches of highways with chargers spaced more than 100 miles from each other. And if you set the filter to show only chargers with 100+kW to screen out 50 kW chargers, you will see large areas devoid of high-speed chargers.
A 50 kW charger will give you perhaps 75 mi in 1/2 hour of charging, while with 100 kW, you can get 150 mi of range in 1/2 hour.
There are big areas of Nevada, Utah, Idaho, and Montana devoid of high-speed chargers. EV owners would do well to stay away from these areas. And even if there are a few, if one is not lucky, he may be queuing behind other EV owners.
