We've gone over this before brew. Mustang/Shelby ownership is a lifelong dream of mine. If the Mach E weren't a chitty crossover SUV I might be tempted

50% increase? 100% increase?

But go ahead and just make sh1t up. Cause your FREEDOM in in the line!

That is correct. Most homes have 200 amp service panels. Costs a couple thousand to upgrade. But, I don’t know of any power grid in the US that could accommodate a 50% increase in demand which is what it would take to power a household charging just one EV. If we mandate out all fossil fuel vehicles then we’re talking a demand increase of at least 100% or more considering most households regularly operate AT LEAST two vehicles.

Damn the torpedoes, full speed ahead.

Anthony,

In fairness I should be more polite about this.

30+ years I have been an engineer, and even I had to check a reference and do some math before I knew an EV would be no problem.
It sounds like power a home does not have - but it doesn't work like that.

As I said, I do it on 150 amp service. In a 3 bedroom, 2-1/2 bath home with a pool and 2 HVAC units. A bit over 2,500 sq/ft in the Texas heat.

Even with 2 EV's, you don't charge during the day when your using lots of power. And you don't often need to change from empty. Charging an EV at home is about like using an electric clothes dryer or your oven. Your home as that power - especially overnight.

And if you need fast charging, you spend 15-20 minutes at a 3 phase, 480 volt charger. Sorry - homes just don't get 3 phase power.

When I did the math on my home, it was apparent that the changes I had been doing made it a no brainer. Loosing incandescent and florescent lighting, having HVAC with a much higher SEER rating, and so on - I really don't need 200 amps of service. 200 amps is based on 20th century calculations - and we are not there anymore.




I guess it pizzes me off to hear so many people say the technology is not ready, or that it won't work. But then again, we are talking about where we will be in 10-20 years. But it works great for me - today.

Most people charge at home and don’t need to get “gas” on the road. Now in the future a Bucky’s or a Love’s truck stop is going to look a bit different. In year to come.

I have 150 amp service at home. I use a 30 amp/240 volt plug in the garage to get a full tank every night.
If I need more/faster I would go to a 480 volt super charge and get a cup of coffee. Doesn’t happen often. In fact it’s never happened.

Right now - most people can't get and EV. The big three have just begun tooling up.
Right now home charging is hit and miss based on where you live. To upgrade your home might cost a lot, or nothing.
Right now EV's are not a practical choice for many apartment dwellers.

2035 - 13 years hence:
Auto manufactures have had EV modules for sale for more than 10 years.
Home and apartments have long had 240 volt wall plugs (exactly like for a cloth dryer) designed in or retrofitted because of the cost and convenience factor.
People who don't want and EV either buy a new PHEV or keep their ICE car.

Now - Then - and Beyond:
People living in a van down by the river still get screwed.

You’re good Scott. I know you’re passionate about your beliefs. What I was alluding to was the reality of what would be required to support a world without petroleum powered automobiles.

Here is my logic. Most homes have at least 2 vehicles. In today’s world most households have at least two wage earners.

During the pandemic many office jobs transitioned to remote. However, many of those workers have returned to brick and mortar locations. Remote work increases costs mostly due to the need for VPN’s not needed in hardwired locations. Especially when a company has a pre-existing fixed real estate cost.

That means that during a 2 to 3 hour period every evening millions of vehicles will be plugging in to recharge for the next day. As a result, there will be a huge increased demand for power during this period. Perhaps a 50-100% increase at this time. After which demand will subside.

To handle such an increase a tremendous upgrade in infrastructure will be required. However, this will be a short window. I wonder if such an upgrade for such a short period be economically feasible.

And forget engineering. You would flunk common sense. Or maybe just plain comprehension.
My scenario was very clearly aimed at long distance driving.
I'll provide pictures next time. You can review them while waiting for your hypothetical super charging station.
(I think Elon Musk has taken more people into space then have used those things. But hey. we've got 13 years...)

Apartments will have 240V wall plugs. (although I've always thought of them as 220/221, whatever it takes).

OK Mr. "infrastructure appears in an instant". In 13 years, you think that every apartment will have at least one 240V plug for every unit.
Even if that proves to be true, what about families with more than one vehicle?
My son lives in Boston. His apartment doesn't have a lot. He gets a permit and parks on the street.
Will all the legal parking spots have these magic outlets? At 240V each?
But forget about the volts. It's the amps that matter when designing the infrastructure. How many amps will we be feeding? At night (when folks are home). With their AC on. Or their soon-to-be-mandated ELECTRIC heat in the winter.

This 13 year vision looks eerily similar to Disney's Tron.
Maybe if dear old Nicoli Tesla had won the war, we'd be able to embrace his wireless concept. But our ac/dc method can't possibly be upgraded to that degree in 13 years.
Hell, maybe never.

But you do love your mandates.

Riddle me this; does a 120 volt circuit and a 240 volt circuit both rated at 15 amps have the same power?
No sir, it is the watts that matter, not the amps. Come on, you know that (remember your engineering).

Glad to see you again showing yours.

Looking at my phone now…the nearest Supercharger station is 10.2 miles away with 2 of 12 station available (there is a great BBQ place next to the station in Grapevine)
At 11.4 miles is 5 of 10 available - slow night in Southlake.
Denton, 12 miles, dead’s as always has 3 of 6 available.
Plano is 13 miles
Dallas 21
Well you get the idea.

But long rang driving - looks like station every 50 miles or so in any direction. Prolly not so good if you live in BF.
