Why EV drivers SHOULD have range anxiety: Half of electric cars fall short on their official range by as much as 50 miles - here are the vehicles with the best and worst

Charging 50kw in a minute is about 6,900 Amps at 440 volts. That’s some big wiring. I wouldn’t hold my breath on that one.

Electric vehicles will always have a disadvantage in the winter; quite possibly a BIG one. You need heat & defrost. You may spend some time trying to get unstuck in the snow. You may get delayed in a storm. And so on...there is no way to predict a usable range in a winter situation. That is only a few of the possible problems with an EV. Not only that, but we are learning of new problems occasionally that were not previously thought of. I have read that the regular service is more expensive also, but not sure how that comes out. Keep your ICE vehicle if it’s still working.

The goal of implementing technology that doesn’t work is to get people off the road.

I wouldn’t touch any EV the way they are now. I am hoping that my ICE cars will get me through what what remains of my driving days. The best thing that could happen is to have people in government who will put an end to these insane mandates. Let the market determine the future of EVs. What a concept.

Yes thanks - I forgot that

That was done in WWII due to the unavailability of petroleum fuel in some places. Wood burning ICE engines tapped the partially combusted gasses of burning wood. I’m not sure how they did it, but I do know from reading descriptions that it didn’t work all that well.

I want to see the EV range at 10 degrees and at 0 degrees.

Every Democratic politician should be forced to drive these things here in the north all January long.

When they got stuck on the side of the road I will be there pointing and laughing.

There are some very rare exceptions where a battery vehicle might be superior. Electric fork lifts in warehouses are still found, but most use propane to avoid the charging downtime. And battery golf carts seem to work for their intended purpose.

Let the market decide. If some virtue signaling twit wants to buy an EV let him, but don’t shove one of those inferior expensive pieces of sh!t down my throat. We don’t need a bunch of communist tyrants (ie democrats) dictating what we drive, when we drive, where we drive, and how often we’re allowed to travel.

Sounds interesting. But a couple of questions spring to mind. What’s the comparative weight between a high pressure H tank and metal hydride storage for the same capacity? How long does it take to recharge the hydride and how complex (read expensive) is the mechanism compared to a storage tank.

The one user group I see an EV might be right is postal delivery where they start and stop every few hundred feet.

AND popsicle trucks and Meter Maids.

[CodeToad]

Sure. Community type vehicles.

Trying to ram highway electric vehicles down our throats is going nowhere.

Our local Ford dealer, in a presentation to the Chamber of Commerce ostensibly to promote EVs, admitted their range was far shorter than advertised. He shared about a trip from Albuquerque to Grants in a Lightning (about 80 miles) and how they realized that they were not going to be able to make it back unless they recharged. Forty-five minutes in exciting downtown Grants waiting for the truck to get enough charge for them to get home.

His point was don’t buy an EV for road trips. In town travel only.

“I’m gonna get myself a 1967 Cadillac Eldorado convertible
Hot pink with whale skin hubcaps
And all leather cow interior
And big brown baby seal eyes for head lights (Yeah)
And I’m gonna drive in that baby at 115 miles per hour
Gettin’ one mile per gallon.”

You're questions are answered in the highly technical literature on line. However, it takes a technical understanding in the science data that makes me think I was kicked in the Joules:

Symbol = Meaning

J = joule

kg = kilogram

m = metre

s = second

N = newton

Pa = pascal

W = watt

C = coulomb

V = volt

One joule can also be defined by any of the following:

The work required to move an electric charge of one coulomb through an electrical potential difference of one volt, or one coulomb-volt (C⋅V). This relationship can be used to define the volt.

The work required to produce one watt of power for one second, or one watt-second (W⋅s) (compare kilowatt-hour, which is 3.6 megajoules). This relationship can be used to define the watt. Much of the charging rates and discharge rates in these metal hydrates are expressed in joules. They don't describe how they compare to the EV batteries on the market. I think metal hydrates are faster with less energy to charge and discharge rates that can create great output currents. The rates of these functions are hard for me to estimate. It is the latest technology and I think smarter people will give better answers than I can.

I’ve never had a car meet EPA estimate. Plus of course the range “estimate” is always a lie, especially as you get low on gas. It’s fun watching that number drop 3 miles in half a mile.

And of course I’m old enough to remember the old days. No range “estimates” just the gas gauge and good luck.

[from occupied ga]

I didn’t expect you to do the calculations, I just wondered if you’d seen them

This is where I found the technical details and the results of the calculations:
