Charging cars at home at night is not the way to go, study finds

"We were able to show that with less home charging and more daytime charging, the Western U.S. would need less generating capacity and storage, and it would not waste as much solar and wind power," said Powell, mechanical engineering Ph.D. '22.

So, charge during peak usage hours and you need less generation resources? Huh?

Tell us what kind of cars to buy. Tell us how to fuel them. Tell us when to fuel them.

Just gimme gasoline.

Here in Arizona, a western state, we need our grid during the day for constant air conditioning. Nighttime charging for cars SHOULD make more sense.

Of course, gasoline and diesel are stored forma of energy. They are quite flexible.

[Brian Griffin]

The sunshine shines during the day.

Solar panels need sunshine to do their thing.

Solar panel farms will be developed to support daytime charging.

Folks in Cleveland should however retain their gasoline credit card. Their ICE cars will need gasoline.

Why the hell do employers have to install chargers at their businesses? That’s insane, like all the rest of this EV nonsense. I’m sure TexasGator will be along shortly to tell us all how to think about this. :(

Right, charge your vehicle during the day, when it’s inconvenient. Sounds great

[packagingguy]

Well solar energy would have to be stored if night time charging is used.

Also the wind doesn’t blow at night so the windmills stop working. /sarc.

Why not put a motor in the car to charge the batteries? Don’t we already do that?

[Leep]

I think peak oil returned during the night.

“Charging cars at home at night is not the way to go, study finds”

hmmm ... because they just figured out that the sun doesn’t shine at night?

Note that it takes 8-12 hours to charge a Tesla 3 at home, or 1/2 hour at a 120Kw Supercharger station, or an hour at a 50kW station.....but using the fast chargers will shorten the life of the batteries, which will cost more to replace than a used Tesla with bad batteries is worth. IOW, a Tesla with toasted batteries is basically "totaled" for cost.

Ain't no way of getting around physics. No miracle cures yet anticipated.

Leave TeslaGator alone!

Over a hundred years ago the ultra superior ICE powered car crushed the steam and EV competition and both of those exotics were dead by the time WWI started.

The left has so mismanaged everything that we’ll soon have no power, no water and no food. Then they’ll blame everyone and everything but themselves.

Kaiser Permanente has about 7,000 workers in their Oakland headquarters. Can we expect them to provide charging stations for their employees to charge their cars during work?

How about all the other large employers who have thousands of workers who drive an hour or more each way to work?

With more than 20 million cars in California, many of which will need to be charged daily, they had better get to work putting in those charging stations!

Why do I sense that workplace charging station mandates will be foisted upon employers and additional inflation pressures placed upon consumers for this manufactured climate crisis???

[Freedumb]

Maybe the headline should read that if we are moving to an EV car model, then generating the power during the daytime (talking about you solar) when people are not charging their cars is not the way to go.
