Yes, that's hard to imagine. Ballpark a megawatt per car being
charged.

Engineers are supposed to have that kind of imagination. John Larkin may just have confessed to not being an engineer.

In this case, the problem of fast charging a a solid state battery could be solved by fast charging from a big static solid state battery at the charging station.

The grid could recharge the static battery between recharges.

Yup. And that "big battery" will be charging one car per day so it could
recharge to provide that megawatt fast charge.

I still remember working at the oil field 40 years ago where we had three 12MW
compressors pumping gas into oil wells ("gas lift"). It is like charging 36
those fast charge cars. Nothing special, just a little thing -- we had a
couple of dedicated high voltage power lines straight from the power
plant...

The story is from 2021...nothing has been added to it apparently.

It would be nice if it worked out, but we all know manufacturers have
marketing departments that don't always know what they are talking about.

As for a megawatt charging, this might make short term storage options
useful - something that takes a while to charge but could release it
quickly under load.

Indeed! So who'd be stupid enough to invest big buxx in installing
that "big battery" with its accompanying infrastructure for such an
insignificant clientele?

No, they will just have a bunch of diesel generators in the bushes
round back.

One proposal for using the fast-charge batteries is to have the car
have three or four charging ports and to water-cool the charging
cables and connectors. Make coffee with the hot water?

The charging cable will be awesome. Definitely not for self-service
charging of Honda Fits.

Well, it's been about 18 months now since I complained about being
nearly run over by an electric car which I couldn't hear coming when
crossing the road and nothing of the kind has happened to me since,
I'm happy to report. That outcome was certainly not expected. I'd
anticipated being run-over with increasing regularity as time went on,
but it would seem I was vastly over-estimating the take-up of EVs.
There's a certain cohort in the population who will not willingly
submit to climate alarmism - and it's much larger than I'd thought and
thankfully, sanity has prevailed.

A lot of elderly people will simply be unable to handle such a heavy
and cumbersome piece of equipment.

Maybe we'll go back to the days of station attendants who wash windows and all that sort of thing. Insurance companies might insist on it. If there's a way to screw up the connection to the vehicle someone will find it. Tired, hurried people make mistakes even if they know exactly what they're doing.
I wonder about the added electrical inspections. Will it be once a year or so?

I wonder if the charging cable will become part of the car. It would be like plugging in a household fan or whatever.
Could some creative soul rig up some sort of cable reel for them? It would take up a lot of space, though.

Why not a (standardized) "dock" that the car drives up-to/on-to and
honking big contacts connect to plates on the underside of the vehicle?
(isn't that how the robot vacuum cleaners take on charge?)

Elderly people can't lift elevator cars either, but don't seem to have
difficulty controlling ascent and descent.

The whole point of having heavy machinery like electric cars and trucks, is that
we aren't limited to muscle power.

What to do about the dirt, gravel, etc. that gets on vehicles? The bad connections would create heat. I live in a rural area. Gravel roads are common.

Would it be practical to use oversized welding cables with connectors like this?
<https://www.tractorsupply.com/tsc/product/hobart-cable-connectors-for-no-1-no-3-0-cable> There are red versions of
this. The connectors could be made not to fit the wrong port.
Two cables would be a bit of a nuisance but could be smaller. Welding cable is really flexible.

The contacts could be behind spring-loaded (or otherwise secured) "doors",
opened as part of the mating "ritual". This would also ensure they
weren't casually accessible by worker-bees...

Burning fossil carbon isn;t the cheapest way to generate energy any more. Wind turbines and solar cells are now cheaper. The message hasn't got to John Larkin yet.

Npbody is going to put a megawatt charger where it would only recharge one car per day.

That would be an expensive solution, but if you were as silly a John Larkin you might go for it

Seems unnecessary. Heavier cables would be cheaper, less complicated and easier to maintain.

It's not showing up in the statistics yet, but the fossil carbon propaganda machine doesn't publish those sorts of statistics.

Not a claim for which there is any statistical evidence.

A certain proportion of the population is out of touch with reality, and believe what they read in Russia Today and the Daily Mail.
They don't think that they are insane - they are out of touch with reality.

I wonder how that would work in snowy places. Nighttime freezing and daytime thawing. The moisture/dirt gets to the charging area during the day when someone is driving then freezes at night when the vehicle is parked. What problems would that cause for the spring loading?
Differing vehicle heights? How to get drivers to properly align the charging components on the bottom of the vehicle with the actual charger?

You can bet any electrical contacts under a car no matter how well
protected, will suffer from salt, water and grit ingress. There's no
keeping it out unless it's all permantently sealed up which of course
it can't be.

Note that this isn't a "seldom used" electrical/mechanical interface.
It will see relatively frequent use as the car needs to be charged
often and would likely *want* to be "kept charged".

So, can be augmented with mechanisms to wipe the contacts clean,
conductive grease to keep out moisture, etc.

Grease fittings under cars are exposed to the elements 24/7/365
yet only need a casual wiping off before being called upon to perform!
Electronics under the hood are exposed to harsh chemicals, the elements,
temperature extremes, etc.

Every year, every driver has to drive their car onto a dynamometer
for emissions testing, under load.

How is it that we don't see folks flying out of the testing center,
at speed, because the drive wheel wasn't on the dyno but, instead,
was on /terra firma/?

You have an incentive to do this correctly. Otherwise, you don't get
a charge. The charger doesn't care if you have to call for a tow!

Why don't we see folks spilling gallons of gasoline at gas stations
because they couldn't line up the hose with the filler tube?
Stations are attended mainly to protect against malicious abuse,
not clueless drivers!

> I used to fix things for a living so I'm a pessimist.

Look at how annoying it is to mate a charging cable to a phone
(Apple got THAT right with the lightning connector; the micro USB
is an abortion!). Yet, people *persist* because they want THEIR
phone to be charged.

Wireless (phone) charging addresses this annoyance -- but, at a greater
cost than a 1 cent USB connector/cable!

[Why do they sell rechargable "cells" that have to be recharged
outside of whatever device uses them -- because the device
wasn't designed with charging in mind?]

Yeah, it's a challenging problem. But, when you consider the
convenience and risk factors, how does it compare to
asking grandma to plug in a cable correctly?

Why can't they make TIRES that don't wear out? Or brakes?
Somehow we find it acceptable to have to MAINTAIN these things.
Surely we could make it easy to swap out wheels instead
of having to "service" brakes!
