EVs as we know them are a dead end. It’s one of those wonderful solutions that look really good until you take a deeper look.

Shouldn't you try to at least give a reason why you think so?

That is a silly statement, as absurd as saying electricity itself is a dead end. The fact of the matter is EVs and electrified vehicles in general are the best answer we've got for the future of consumer mobility. Nothing else really competes long term.

We were thinking to add PV to the roof of the office for daytime charging of employee cars. The cheapest power, and the right time to use it

That's one way to get 'em back in the office! :)

Except if they were really serious they would have just eliminated the need to spend that energy driving into the office by allowing WFH.

The solution to this is going to be have customers enroll in smart charging. Keep your car connected to the smart charger when not in use and during times of excess power charge the car for a few cents per kw.

So, the solution to "the solution" is to allow the government to control more of the market? Who will enforce this? What will the penalties be? Or, do we just raise power prices for everyone and then give them a break if they allow a third party device to restrict their power usage? Seems like a great way to subsidize "the solution" on the backs of people who can't afford a new EV of their own. Also.. when are there…

The grid does and will increasingly curtail renewables. If they had a demand queue of customer cars to send that power to, they do that instead of curtailing it.

This is not a penalty situation, it is an enticement. Smart charge rates of 4 cents instead of 20 cents a kw/h. People will voluntarily do this to save themselves money.

Why bother asking these types anymore? It's just going to the same debunked propaganda over and over.

We have the means to balance grid usage by telling specific families at which time they should charge their vehicles.

Families who are not at home during the allotted time won’t be able to charge.

People charge at night because home charging is the only practical way to own an EV and most people work during the day.

Fix the charging situation first — but be aware that more convenient charging will induce more demand for EVs from apartment dwellers, which will increase demand for electricity overall.

The only real solution is to improve the power grid so that EV owners can charge whenever they want.

Yup, let the tech overlords plan your life for you for the greater good. Fuck that fishing trip - your energy company decided you’re not important enough to have a charged car.

Simple answer is just "congestion pricing". You want fast charging at peak hours, pay double. If not, set some price optimization. And set it to prioritize the first 30% of charge to never be stranded but always wait for cheaper power to fill to the top. If you've got a fishing trip, plan ahead or pay extra. That's just free markets.

Is there currently distinction between electric for charging vs traditional uses at the residential level?

That already happens. PG&E charges differently at peak times in California, for example. People just pay for it anyway because they can’t plan their daily lives around the power company’s preferred times.

I'd say that plugging in a car should mean - charge it enough to get me to a hospital. Beyond that wait for the optimum charge time. However there should also be a screen that overrides this if you are going on a trip or something.

You mean like how companies have always decided who gets gasoline, when and for how much anyway?

EVs already have the capability to schedule charging around time-of-use electrical pricing and also a way to charge now regardless of price.

I suspect this capability will only improve over time up to an including the ability to dump power back into the grid from the battery if the electric co is willing the pay enough to make the battery wear worth it.
