About those EV home charging systems...

I've been musing re home EV charging. I have no expertise beyond common sense but there will surely be practical considerations involved...

Let's say we have a surburban family with mom, pop & children all driving EVs. How many can be charged at once? I am thinking a multi-EV charging system and the necessary electrical capacity to safely power it would both need to be heavy-duty and therefore quite expensive. ka-ching and then you get to pay the electric bill!

If this home only has a minimum power charging system requiring hours to charge a single vehicle, there would be EVs on that charger constantly - and squabbles about "I'M next!" Btw, the insurance companies will note these systems and surely raise their rates accordingly.

Scenario 2: Same residential home but Mom & Pop are travelling for a week. I can envision Junior or Miss Cutie Pie telling their friends "Sure, come on over! My parents are gone for the week, you can use our charger all you want." More ka-ching on the power bill.

On a concurrent note, I've read speculative posts on how once a residential neighborhood reaches sufficient EV saturation, the electrical distribution serving them will necessarily need to be strengthened to handle all the extra required capacity. Someone must pay up for these modifications.

“In the high rise apartment areas, every inch of real estate is already in use.”

No place to park, no car, no need for a charger.

2-3 days! Even 18 hours is incredibly long.

No current/amperage stated, guessing it’s like running an electric clothes dryer on high heat for 18 hours. Reddy Kilowatt loves EV’$$$$$$.

Ooof!
No more guessing, it looks quite pricey for you and lucrative for your electric utility provider. Amp draws per charger listed here.

Thanks but I’d prefer to have real-world users comment on their sub-freezing experiences.

And he was referring to ICE cars!

I would not want to live in a large building with a lot of EVs being charged in the parking decks below the building.

“I you have the most common 100Amp service then you will using 40% of your available power to charge your EV. That is only one RV. So if you have 2 charging circuits charging two cars at one time then it would 80%.”

Most will not need to charge at full capacity most of the time.

You apparently don’t know about high rise parking garages.

If you don’t think there are cars in New York City, Boston, Atlanta, etc, maybe you should visit them in your car.

I am a little surprised. TX has some pretty big cities and every one of them I have visited had more than a few cars. Plus trucks, buses, construction equipment, whatever.

“2-3 days! Even 18 hours is incredibly long.”

Do you put 18 gallons into your. gas tank every day?

Amen.

I would not even park a car in a garage connected to the house. Mine are in a separate building 25 yards from the house.

Gasoline has its own peculiarities.

10% loss.
In a vehicle that has a mileage rate based on battery power seems like a bad deal for cold weather climates

You can take longer trips when the weather improves :)

Take shorter trips till weather cooperates
Or buy a winter rat that may have battery issues but you can go get one at Auto Zone..

We plan on keeping our ICE vehicles, but will add an EV. We have pre ordered an Aptera, which besides being the most effecient EV (production should start in first half of 2023) available, is solar capable of adding up to 40 mph range per day in optimal conditions from the sun . 4 iterations will be available. 250 mile range, 400 mile range (which we chose), 600 mile range, and 1000 mile range. It is a "funny" looking vehicle and only a 2 seater. But this is fine for us, a semi retired couple who only make long road trips occasionally. That is why we will still keep our ICE vehicle (2018 Subaru). The Aptera will be capable of using any charge level, including standard 120 volt house outlets, which will give 100-150 miles of range on an overnight 10-12 hr charge. If we only use it for my wife's commute to the bus barn where she drive's school bus, we will NEVER have to charge it. Of course we will use it more than that, but that gives you an idea on how fantastically efficient it is. Take a look at it. It might be something you're interested in. It answers a lot of the negative questions surrounding EVs. It is definately a niche product. But it fits our niche perfectly. Check out the link below. If you decide to get one, use the discount code below. It will save you $30 off the $100 refundable reservation. Aptera pre order discount

“You apparently don’t know about high rise parking garages.”

You said there was no space for chargers. If they have parking spots they have space for chargers.

Everybody knows that.

Wait till the rebels start disabling the grid.

“Take a look at it. It might be something you’re interested in.”

I don’t think is interested. His “musing” was just a way of introducing his anti-EV rant.

“Porsche is installing 350 kw stations.”

There were 286 million cars registered in the United states in 2020. If they are all replaced one-for-one with EVs, how many charging stations wound that require and how much generated electricity?

For when your battery pack goes out...

Possibly. When I said "You're" I meant that generically, for all readers.

I got a good laugh out of that.

And a BINGO to you.

He is more interested in showing how clever he is than he is in facts and logic.

And we are supposed to include him in our address.

And as for the claim that the present grid can handle the potential load, there are a couple of problems with that.

#1 We do not know what the potential load will be. All cars or only a few....all trucks or none. How many construction machines; cranes, paving equipment, front end loaders, excavators?

#2 But we do know that both Texas and California have already demonstrated that they have very serious grid problems and they are a warning to the rest of the country.
