The Times They Are A-Charging

[Bill Pemberton]

The one thing I don't fear at all is the likelihood that driving will go away entirely to automated machines, because that is one privilege I don't believe folks will ever relinquish. Similar to the rebirth of motorcycle , where the purchase for many was just the freedom to get out and ride, with yourself in complete control. That phenomenon , some feel , saved the Harley years back and opened up another complete sales avenue for two wheeled horses. We may get to a different point many years in the future, but the personal driving device we wheel down the road will live on --- humans love that tactile experience!

Electric vehicle drivers get candid about charging: 'Logistical nightmare'

Charging an electric vehicle on the go is neither easy nor fast.

Coz,

Good article and part of the reason I think those who are concerned about a full EV switch will realize almost everything in the World involving changes in infrastructure always take longer than predictions. I would be surprised if we are full electric by 2050 and even then I think there will be a percentage of ICE/Hybrids. Those of us TMO OFs ( old farts ) will be going to the grave still seeing ICE machines running all over. This is a World mandated change, so we will continue to compete with our industrial complex, to stay in the lead, but it will come slower than projected, so I shall stay mellow and my main recharge will come every morning in the form of caffeine!

This past Xmas Eve I went by a local Wawa convenience store that has a gas station and 8 Tesla Chargers on the side. The out of towners visiting their non-EV relatives were queued up around the store.

Shocking...............and they probably don't take cash, you have to use a charge card instead, ha! Ok, I am going back to my room now.

Ugh...lol

Very impromptu "dad" joke. I liked it. Must be showing my age. Now where's my walker.....

You Need an EV Emergency Response Solution Today

The number of electric vehicles (EV) on the road is rising exponentially, and our emergency response must adjust accordingly. Electric vehicles pose several unique issues and challenges for firefighters. They burn hotter, they burn faster, and they can start on fire without warning.

Chile's plan for state control in lithium dismays business

The Chilean government’s newly announced plan to have the state take a majority stake in the lithium industry has disconcerted business leaders. But analysts cautioned Friday that the proposal appears to try to strike a middle ground between competing interests. President Gabriel Boric announced...

Was curious and checked out the article. They are using suspended abrasives in water at 300 bar ( 4351 psi ). To me it sounds like a high pressure dustless sand blaster with maybe less grit and a fine jet or some type of mobile water jet with a fancy name - "cold cut cobra system, cobra ultra high pressure lance"

When I was a firefighter we had a "piercing nozzle" that we used to try to get into inaccessible areas. It was strictly brute force and normally not able to go through thicker sheet metal.

In this case the technology is intriguing. But I wonder how effective it will be in practical use. It seems that may require a lot of poking & prodding to find the battery cell involved. Just like structure fires, it's tough to pinpoint the source just from the smoke. And if you're going in from the side and the overheating cell is in the middle, how long will it take?

By that time, the contents of the car and other cells may be well involved.

We'll see what they run into in real life.

I have the solution, all battery packs on a vehicle must be inter-connected with 2 inch fire proof tubing and 4 standardized quick connect fittings. fire fighters simply arrive on scene, hopefully one of the 4 fittings is accessible, plug in hose and fill until battery compartment pressure release valve pops. Better yet all EV's equipped with a foam fire suppression system? Lastly, just fill the battery compartment with water/anti-freeze mix. I got up way to early today and my brain is running WOT.

As the West surges toward electric cars, here’s where the unwanted gas guzzlers go | CNN

Standing on the stony ground in the bustling Fifa Park car lot, Rokeeb Yaya is haggling over the price of a dark red car. It is one of a couple hundred vehicles, parked in long lines stretching out across the vast lot – some shiny and new-looking, others dented and dusty.

Except that horsepower and torque are two ways of calculating the same energy output. If you have one, you have the other. I guess they need something to write about. Lol.

 

[Dave_W]

Lucid’s motors can actually drive upwards of 5,000 lb-ft of torque into the axles, but because the tire diameter reduces that by adding a larger radius (again, think of the wrench, in this case usually just over a foot) into the equation, estimates of the Sapphire’s real wheel-torque are more like 1,600 lb-ft.

Pretty good explanation and math up to this point, and then he gets this completely wrong. Tire diameter has nothing to do with torque, because the "foot" part of "pounds-foot" reduces it away. What tire diameter (actually radius) does do is create the divisor when converting pounds-foot of rotational force into pounds of thrust at the circumference of a circle - the forward thrust the contact patch of the tire is applying to the asphalt. But if he really means 1600 pounds of thrust at the contact patch from 5k lb-ft of torque, that would require a tire radius of 3.125 feet. And I don't think the Lucid Air Saphire is a Monster Truck.

With lots of caveats and hand-waving, horsepower is how fast you can go (top speed), and torque is how fast you can reach that speed (acceleration). I once read an interview with the then-head of Audi North America, who I think was actually quoting GM chairman Bob Lutz when he said, "Americans buy on horsepower, but they drive on torque."

These "talking heads" write all this click bait crap and mostly don't know what the hell they are talking about. Cut and paste, here you go boss.
