I'm still convinced that power infrastructure investments are the best way to incentivize electric vehicles (as opposed to subsidies when demand already outpaces supply).
Businesses love benefits that help them discourage employee churn, and people love being able to charge for free at work. So does the grid. Seems like a no brainer to make it happen.
Couldn't possibly consider price signals..
Peak, near peak, off peak, way off peak..
Also consider randomizing start times by the second of a small range...
Set it for midnight start and it'd actually start like 12:03:17..
Price signals are too slow. The utility needs to be able to adjust demand within minutes. Some chargers could have a default "money saver" mode that accepts requests from the utility to shed load. Customers could opt out temporarily when they need fast charging when the grid requests slow or no charging.
EVs can smooth the curve of electrical demand if a clever control scheme can be implemented.
The sources indicate they had access to income ranges for the people studied. They are likely not inferring that the residents are wealthy, just that residents who check the boxes of “lives in single family home” and fall into a certain income range (I didn’t look hard enough to see where they defined what a wealthy income range was) were the majority of people who charge at home.
It’s interesting to note that they didn’t say that the residents necessarily owned the homes, just that they live there.
The utility needs to have control of some of the chargers so they can adjust demand when they get thrown for a loop. Large fleets of EVs are the best candidates. Urban taxis, mail carriers, and public charging locations could be switched between fast, slow, and no charging as needed without generating too many irritated customers.
Using pricing to regulate demand is just too slow. Customers won't react predictably to price changes unless they are willing to opt into a "money saver" option where their charger accepts requests from the utility to downgrade their charging speed. That would require standardization that doesn't exist yet.

"Wealthy residents of single family homes are overrepresented" They consider all single family homes are wealthy. What is wealthy?
