> Current time-of-use rates encourage consumers to switch electricity use to nighttime whenever possible, like running the dishwasher and charging EVs. This rate structure reflects the time before significant solar and wind power supplies when demand threatened to exceed supply during the day, especially late afternoons in the summer.

So, if you have a grid that doesn't heavily rely on solar then charging at night makes sense.

How are people going to charge their cars during commutes?

Come on, you're saying most commutes are "late morning and early afternoon"? I too would like a job where my commute in is at 11 and my commute home is at 2.

Rather than spreading EV FUD, can we instead discuss what the article is actually talking about, like installing charging infrastructure in daytime parking lots so we can take better advantage of the cheap, plentiful, and often curtailed solar energy?

We should install solar panels over those lots at the same time. It covers some of the capacity need, cools the lot and the cars, and is an efficient use of space.
It would also conveniently reduce transmission loss, and if you did it right you could probably skip the inverter overhead by going all DC.
My post wasn't not about criticizing EVs. My post was about criticizing the energy grid. I think "slow" charging over night is the best way to use EVs and an energy grid that cannot accommodate that (because of a predominance of PV) should be criticized.
Is a level 2 charger not slow enough? Running that for 2-4 hours should be enough for normal commutes I imagine.
I was referring to level 2 chargers.
From the article:

> drivers should move to daytime charging at work

Late morning and early afternoon. So, basically, people would charge their cars where they park them during the day while they work, not at home while they sleep.

Seems very doable to me.

I appreciate that you acknowledge Californians show up late and leave early
Only in Sacramento
Most people wouldn't be commuting then, but this could be an argument for employers to supply infrastructure to facilitate charging during the day while at work.
