Battery based electric vehicles of today and tomorrow.

Sounds like grocery getter pickups for now vs long trip towing vehicles. Nothing wrong with getting groceries.

The charging stations could have local power storage. I read an article not long ago about using flywheels to store energy. A big flywheel can store an impressive amount of power, and release it quickly for a 20 minute charge. Then it could gradually spin up again, stabilizing the load on the grid.

50+ years ago there was talk of using a flywheel method to power city buses. They come in handy on a hay baler with a small tractor as well.

Molecular Machines: NanoGear – Mechanics of the Infinitely Small

While Italy has been a leader in the minds of many of us "gear heads" they are taking the concept of gears out of human sight. Just wrapping our heads around buying a car without a gas tank, transmission or starter is huge and now this.

250,000 to 350000 watts chargers. holy crap, how is the power grid supposed to support this.

What are you, an electrician or something ?

l'll pick on the obvious target, Cali. Today, the wind blows, and they can't/won't keep the grid up.

Waive the Magic Wand, and that problem goes away.....

Brownouts or worse during heatwaves are not unheard of...... M Wand time again.

USA is well ahead of us right now (I sit here, locked down under Wuhan War III at the moment....), so let's use the M Wand one more time and pretend that people and holiday and traffic patterns return to normal....

It's coming up to July 04 long weekend, and the M Wand has held off all those other issues in LA. Thursday night, a million or so fractional MegaWatt chargers plug in, to get ready for the holiday weekend drive.....

No Worries, wave the M Wand one more time...... and give the LA grid Viagra.....

I guess the best thing to do is when he visits you with his gasoline/diesel vehicle go ahead and fill up his tank. That is what people did in remote areas before filling stations were everywhere and you lived very remotely. I learned this from the tour guide in a remote Lake Tahoe Nevada Mansion when guest from the California coast would visit. (Just a hundred years ago . . . .)

Time always Rolls Along....

None of us were alive when gas engines debuted..... gas was so scarce in some areas, you went to a pharmacy, druggist, apothecary to get fuel...

Lots to learn, from actual History....

Did Ford just damage their chance of long term success by suggesting the Lighting is light years ahead of the F150's on their lots today?

I often listen to this guy from Denmark.

Interesting video.

You'd think Osborne would be required Marketing 101 reading.... but I'm getting old, and tend to forget, people don't read anymore....

While there is no shortage of public Virtue Signalling on the horizon any time soon, it's a bit surprising that Ford went as far as they did, trash-talking their present (and pretty much only) golden-goose.

Detroit has long regarded small car ICE production as a losing game, and Ford killed most of their traditional car production some time back.

Elon's evangelical style works, but folks and companies should think carefully, before blindly adopting same....

Reading on electricity in Denmark....

Electricity sector in Denmark - Wikipedia

Denmark is a net importer of electricity. The flow of electricity between Denmark and the countries it has interconnectors with (Norway, Sweden, Germany and the Netherlands), and the direction of that flow, is highly variable and depends on current demand and current Danish wind power output.

Danish average consumption of electricity per person was 0.8 MWh less than EU 15 average in 2008. Denmark has average electricity costs (including costs for cleaner energy) in EU,[2] but general taxes increase the price to the highest in Europe.[3] In 2015, supply security was over 99.99%, among the highest in the world.[4]

They tried flywheel UPS’s in the 70s and 80s, didn’t work out. Everyone went to static with battery backup.

Newsom orders ban of new gas-powered cars by 2035

In a dramatic move to tackle climate change, Gov. Newsom announced that the state would ban new models of traditional cars beginning in 15 years.

when they shut the grid down they are going to have one heck of a time bringing it up with all those ^^^^ cars wanting to charge dead batteries.

Remember all new CA homes come with roof top solar panels to charge your EV.

 

[grsthegreat]

Ya right. An ev that needs 50-80 amps to charge. Id like to see an arrey that can output that level of power for 8-12 continuous hours.

Good point. After losing power, you'll have to remember to start the charger back on.

Sounds like you must have a 200 HP electric tractor that you use all day.

People that have 8-12 hours daily to recharge are fine with a 15 amp 120 volt outlet assuming they only drive the average 30-40 miles daily.

Since we had 220v on a 40 amp breaker to our detached garage I set up to charge using 220v but the max the Leaf on board charger can draw is 26 amps and it tapers down from there.

Charging an electric car isn't as demanding like arc welding.

What voltage do solar panels put out? 24V? 48V? More? Less? Ohm's law says half the voltage, twice the current for a given amount of power. Also keep in mind that inverters are not 100% efficient. Sounds like you'd need a pretty hefty array. Never mind that most of the charging would likely take place at night when those panels aren't putting out anything.
While the draw of a car recharger isn't that of a welder, neither is anyone running a welder at 100% duty cycle for 8+ hours straight either.

Solar panels are not used to directly fast charge EV's or power your AC powered TV or frig.

Wow the Lighting is not like any 2022 gas F150.

But more people are moving out of CA than in. So new homes there are not what they projected.

The same thing is going on in WV I read this morning. Not all states will be EV ready perhaps.

I think they are talking about a flywheel the size of a house, not a flywheel in the house. The flywheel could act as an armature for a big motor/generator. Plus, it would not be a UPS, it would just even out the load. If the grid goes down, so does the flywheel.

On the down side, the suckers would be big. 30' in diameter and 10' tall, plus the control electronics, bearings and enclosures. Maybe they could dig a hole and put them under the charging stations?

There's no doubt the US needs a massive update of it's creaky electrical distribution system, but rapidly evolving demand will make designing it a nightmare.

The new ford advertisement for their truck says it takes 80 amps for 8 hours. I’m not making this up. and I never only drive 30-40 mile a day. More like 200 doing service calls.

at 80 amp charging, they say the truck will get 30 miles for every charging hour. Then again they say

With Ford Intelligent Backup Power, enabled by the available 80-amp Ford Charge Station Pro and home management system Ford can help install, F-150 Lightning automatically kicks in to power your house. Once power is restored, the truck automatically reverts to charging its battery. Based on an average 30kWh of use per day, F-150 Lightning with extended-range battery provides full-home power for up to three days, or as long as 10 days if power is rationed, with results varying based on energy usage.

i install generators for a living. Nearly every one is a 22kw generator. How can they say the national average power use is 30 kWh per day. If you run the numbers, this is rediculous assumption. No way in he** this truck can operate a house for 3 days, unless there only running refer, freezer and a few lights. Add in wells, elect heat, heat pumps, ac units. Their nuts.

hows that old saying go......figures never lie, but liars always figure.
