While I agree that the grid needs rebuilding, I don't think it is as dire as "every EV will be doing a full recharge every night". Every ICE is not refilling their tank every day (outside of pandemic buying); I would have to think that a "smart" charger could simply be told when the car is needed, and then charge at a corresponding rate. For example, I get home at 6pm, plug in and set an alarm for 7am departure--the car knows I want the interior at 70F and fully charged by then, and it figures out how to do that for me. If that's a trickle charge for 12 hours, or a fast pulse charge at 3am, I don't care.

Does anyone know what the utilization of the grid actually is? I mean, when CA starts doing rolling blackouts, I'm not sure if that is the powerplants not keeping up, or the wires themselves overheating. Regardless: the wires (the grid we are discussing) can only pass so many amps. What is the typical percentage of usage, winter vs summer? Are we running at 90% already and thus have no overhead? or are we at 50% and assuming that it's just going to fault out?
