A feature, not a bug to the high and mighty.
Sorry, I meant the previous post for Boogieman.
From the article: “The transition of battery packs from wired to wireless connectivity enables automotive manufacturers to scale their electric vehicle platforms across multiple vehicle models to meet growing consumer demand,” Patrick Morgan, VP of Automotive at Analog Devices, said.”
That’s a joke. By all reports there is no ‘growing consumer demand’. Other articles in WSJ indicate that dealers are having a tough go selling EV to consumers.
More from the article: “With this flexibility, GM can pack in anywhere from 50 kWh to 200 kWh of energy capacity (double what the current largest Tesla battery, the P100D, can hold), translating into 350 - 400 miles of estimated range and a 0 - 60 in as low as 3 seconds.”
So how long to recharge these batteries? On a long trip, I can refuel my gas car in five minutes or less. I really don’t want to wait for an hour or two to recharge.
With President Trump, we didn’t need OPEC. We were a net exporter of petroleum.
From the article:
What’s more, the Ultium system is capable of handling an 800V electrical architecture. That is, most mainstream EVs on the road today (luxury models like the Porsche Taycan, Audi e-tron GT and Polestar 2 being exceptions) as well as a majority of the DC fast charging stations, use a 400V standard, which limits the amount of energy a station can dump into your car’s depleted power cells to around 200 kW. With an 800V architecture, a DC station can pump as much as 350 kW across its line — more than double that of Tesla’s 150 kW limit. This should enable Ultium vehicles to charge faster — GM claims it can add 100 miles of range with 10 minutes of charge time — and also output some of that power to other devices (even other EVs) using an Integrated Charging Control Unit (ICCU).
“Gas stations need to be equipped with charging stations that take 10 minutes to charge. “
I don’t think such a charger exists.
I didn’t see any tow ratings for the new 1000hp Hummer.
thats only partly true.
OPEC has strong influence on price in US
even if US does not import from them
EV's ca.1900 were getting 100 miles per charge. And now 300 miles per charge is considered great. What a quantum leap!!!!
11,500lbs
One question. Where is all the electricity going to come from to run these charging stations? We’re shutting down coal, oil and NG. We’re building no new nuclear plants, and all the usable rivers have been dammed. Wind and solar supply 6-8% of our total power now with little expectation of massive output growth. Can’t speak to the international supply if fairy dust and unicorn farts.
Patience Grasshopper patience.
Batteries are very bulky and heavy
My experience has been recently with these electric bikes that are out there
Those bikes weigh 60 pounds mine weighs 30
So therefore you’re just going to be restricted on a bike that has a battery on it
Same is true with electric vehicles
Case in point: range
To get 400 miles out of an electric vehicle you’re gonna need a lot of batteries and it’s gonna be very bulky
You simply cannot run a battery car in the very cold weather
Batteries take a long time to recharge
Electricity is also expensive unless you make it yourself for solar panels
The killer for me as well if you run out of juice and you’re nowhere near anything
It’s an electric bike you’re gonna have to push that thing up the mountain
your car you’re just kind of screwed
I get it I get Tesla. They’re FAST AS HELL. ELECTTIC MOTORS ARE VERY EFFICRNT
but just give me my gas powered vehicle any day
One thing you don’t see on the desert highway between Bakersfield and Las Vegas:
Teslas.
And you don’t see them on the highway between Palm Springs and Phoenix either.
Do you have a citation for the100 miles range assertion? I’ve never seen a number remotely close to that. Thanks
I am fine with EV vehicles, provided there is ZERO subsidies or tax credits of any kind for them.
Also, I think EV sales should be halted, until the states and federal representatives legislate taxes for EVs that derive an average equivalent level of taxation as the fuel taxes - without taxing “miles driven” - with all the data collection THAT will require.
Lastly, the battery industry either has to self-clean-up the pollution pilling up in the mountains of used car batteries, or have a tax applied to batteries to pay for public efforts to do it. Batteries should not be permitted in landfills and should be sent to outfits that break them up and break them down, recycling what can be recycled.
It is hypocritical to refer to the EV industries as “green” and not polluting when the massive increase in battery use already here, and set to be massively growing, is just changing one pollution issue for another, and so far its largely being ignored.
“Gas stations need to be equipped with charging stations that take 10 minutes to charge.”
I’m going to open up a combination charging station and massage parlor. Charge and discharge.
Where does the power come from?
I will say one thing for GM it is the only corp. to be forcefully split four times by the government.
“So how long to recharge these batteries?”
Depends on how much power the charger can put out. A 200 kWh battery will take at least an hour if the charger can pump 200,000 Watts. If you want a 6 minute charge time then the charger must provide 2,000,000 Watts. And I’m not going to be comfortable with 2 megaWatt cabling. 2 megaWatts per charging station is completely ridiculous, if us consumers are going to do the hookups and charging, 10 kW is likely going to be tops.
Charge times go up if battery inefficiencies and issues like heating up are considered.
