It's nice to be able to hand wave away the problem. "A few hours" is "10 hours", and the instantaneous energy for each of those is very high. When I charge my EV it doubles my normal peak electrical usage (in KW, instantaneous) and quadruples (or more) my average KW usage.
In my new neighborhood a set of ~5 homes is connected to a 50 KVa transformer. Those five homes charging a single vehicle each at the same time is enough to overload that transformer even with zero other demand. That's a real problem.
My understanding is that we're talking about a doubling of demand. Are we ready to double all of our electrical generation and transmission infrastructure?
