Why can't most people slow charge EVs at night while they sleep? Seems like an easy choice that won't lead to any problems for the user or the provider of power.
Frugality and commonsense used to be national virtues. Now it is all about entitlement and what's in it for me.Common sense is a rare commodity. . Adding an economic incentive to reduce their peak loads and do load shifting may get some folks over the fairly "low fence" but many people assume that power from the grid is not anything until its gone. Talk to any rural person who has to run off a generator for a few days and they will be very much aware of load shifting and peak loads.
That's cause every Facilities Manager wants the 240v 50amp charging circuit, times 5 parking spaces, because every FM knows bigger is better. Most employees could do quite well with a 240v 16amp EVSE. Connected for 7 hours, that's about 23kwh into the car battery assuming 85% efficiency. At 3 miles per kw (most little EVs do better), you won't need to charge at home.I was on the phone the other day with a firm that does a lot of commercial buildings and EV charging is giving them fits. It turns out that the building electric load is minimal compared to the possible EV charging load if everyone plugs in at the same time when they drive into work. To make it practical there has to be some load management of the chargers or the wiring and support equipment gets vastly oversized.
Around 3 miles per KW . If I do lot of local driving in the 40 to 50 MPH range it goes up to 3.1. Some folks claim 3.3. Its very outdoor temp related, the battery is kept within a temperature range with either heat or cooling from the HVAC system.That's cause every Facilities Manager wants the 240v 50amp charging circuit, times 5 parking spaces, because every FM knows bigger is better.

My company's building (I work there, I don't own it) is supplied 120/208 3-phase in the utility room, so it's really limited. But we got 3 parking spaces with 16amp level-2 Clipper Creek EVSE's happily running at 208v. The plan is to add 3 more spaces in the Fall.
What kind of miles are you getting for each kw into the battery?
I think the issue is which state gets the revenue. An example is many folks live on the NH border but commute to Mass due to lower overall NH taxes. So they are putting wear and tear on Mass roads yet NH would most likely collect the pay per mile fee as most pay per mile schemes are tied to recording the data during annual inspections. It also may be tricky if one state puts in pay per mile and one does not. Not all state require annual inspections so how would the data be recorded? Oregon is looking at it and Illinois reportedly do it with trucks but I havent looked up any details.
Folks are getting pay per mile car insurance usually combined with nanny software that detects unusual vehicle operation like aggressive acceleration, hard braking or operation over the speed limit. That effectively allows the insurance company to pick low risk drivers who are more profitable. They usually get the data from a plug in device on the OBD port. Many new cars now have cell phone transmitters in them that communicate to the manufacturer so it would not be hard to piggyback mileage data to a state via the manufacturer.
Of course pay per mile hits the folks in rural areas far worse than in urban areas so its another regressive tax.
EV's are not damaging roads, big over the road trucks tear up roads, along with plows and other winter stuff.
