As you say, it is already possible to charge at high level today. For example, I already have enough power supplies in my garage to create a 24kW charger. Making a 100kW charger should cost not more than about 2k$ in power supplies, plus any smarts that might be needed (and an upgrade of your electrical service). The supplies that I have here are already plenty to overload my entire house service (240V, 100A)

If someone wants to make a 300 mile trip, they're going to need to recharge somewhere along the way. Early adopters won't mind waiting an hour to charge, but I wonder if mainstream people would trade in their ICE with charge times that long. For example, to charge a 50kWh battery in 15 minutes, one would need a 200kW connection. I'm concerned that we'll be spending a fortune on infrastructure only to find it becomes outdated by the time it is installed. Am I being too optimistic or is that still beyond what the standards group thinks is going to be needed in the next 10 years?
