You're taking an extremely optimistic view of things there Mark.

Will electric vehicles be mainly charged at off-peak hours?  That's a good theory and it might even hold up in reality, though I haven't seen it studied yet.  This is somewhat odd to me as there are enough electric cars out there to get at least a rough approximation of when people actually DO charge their electric cars rather than when people think they should charge them.

I would toss out a guess that MOST owners of electric vehicles will mostly plug them in when they get home from work, probably at about 5pm.  If so that would be a BIG problem because that closely aligns with peak electricity demand summer months.  Obviously there are some simple technical changes that could help here, but are they being used?  Note that I did not say "CAN they be used?", but "ARE they being used?"
