It will be interesting to see if there are any incentives for vehicle owners or manufacturers to adjust charging times across the grid. For example, all Tesla's in a time zone could communicate and decide which random hour they would begin charging that night so everyone doesn't hit at 2am. My iphone now doesn't charge immediately at night as it understands my typical schedule and just ensures the phone will be full when I wake up. I expect similar capabilities for electric vehicles.
We already have "demand pricing". I know of some companies who transitioned to electric vehicles (think skid loaders and other yard vehicles) who had to install their own battery systems and generators because by the time the vehicles needed to start charging, they were hit with way way higher than normal electrical prices.
I dont know the specifics- i.e. if not all of their vehicles could go a full day of charging- but only that yes, there are mechanisms in place to force those who can afford it to adapt.
Everyone else has to hope they can plug into a smart grid that only actually charges when the price drops.
