Tesla Launches Supercharger V3 With 1,000mph Charging, Better Efficiency, and More (electrek.co)
Yesterday, Tesla launched the next generation Supercharger V3 with higher charging capacity, better efficiency, and more. The biggest new feature is the ability to deliver a new 250 kW of peak power thanks to an "all-new liquid cooled cable design." Electrek reports: According to the company, the cable is "significantly lighter, more flexible, and more efficient" than their current air-cooled cable found on the V2 Superchargers. Other than the cable, the Supercharger V3 should be undifferentiated from V2 at the station. The company didn't even release new pictures for V3. The new 250 kW peak at the station is also enabled by a new 1 MW power cabinet. Instead of using onboard chargers staked together, the new Supercharger is built using technology Tesla developed for its massive grid energy storage system. With the new technology, there will be no power share between stalls like in the current version.
On Tesla's most efficient vehicles, like the Long Range Model 3, the company says that the new Supercharger V3 can add up to 75 miles of range in 5 minutes and charge at a peak rage of 1,000 miles per hour of range. A new 'On-Route Battery Warmup' software feature was also announced. When entering a Supercharger station in your navigation system, the vehicle's software will "intelligently heat the battery to ensure you arrive at the optimal temperature to charge." That's assuming you have enough charge in the battery when you come in. The new feature alone should reduce "average charge times for owners by 25%," according to the automaker. Model S and X owners may be disappointed to hear that the new peak charging rates won't be available for their vehicles at launch. Instead, they will have to wait for a software update "in the coming months." Model 3 vehicles will be the first to receive the software update to support the new speeds.

You have to reach Mach 1.35 before it starts charging?

The latest chargers installed in Europe are 350kW, with 500kW rollout beginning.
The main issue is that most cars can't take high enough voltage to make it practical. The Audi eTron will be the first to hit 350kW most likely, at 800V.
It will be interesting to see what Tesla to to get their charging up to 250kW given the lower voltage of the battery packs.

Tesla is more than Musk.
Congratulations to the engineers working on this stuff. It sounds great!
Yep - shot into space at 1000 mph.

I think it refers to the rate of power delivery compared to the rate of power draw a vehicle woul duse to go 1000Mph.
example, suppose that sustaining 100Miles per hour in air drag were to require , to pick an approximate number, 25KW of engine power. Noiw scale this by 10. that's 250KW and 1000Mph. I'd actually say that the real number is about half that for most cars. so really this is 550MPH charging that someone rounded up.
Now this is wonderful in the sense that it's actually the unit you care about. If you are using your car sustainably on a drive across the country then if you have to recharge it every 5 hours for 5 hours then you aren't going to get far. it it takes 5 hours to recharge 5 hours of drivine then the rate of charging is equivalent to your rate of travel when moving. e.g. 60MPH. so if you can do it ten times faster then it takes ten times less long. It's a convenient unit as perplexing as it sounds.
One the other hands it's fundamentally insane. Asking a member of the public to make connections that carry megawatts is Bonkers. And in fact it never will be anything but bonkers... ever. The only form of dense energy storage that we've come up with that is not so explosive is in fact gasoline. It's redicluously safe when you consider the crazy amount of energy you are transfering when your hand is on the gas pump handle. Electricity isn't that safe. I don't think it can ever be. Megawatts of power just burns holes in things at the slightest resistance. Even a 1 ohn resister would melt metal instantly and probably spray plasma.
there's a reason why our houses have 110 volts. It's the transition point between air gap jumping plasma arcs that are self sustaining st elmos' fire death and spakes that just damp out. Get up to 480 and you are wielding plasma torches. Likewise 20 amps is where things like small resistances in connections start to just matter but can usually be managed.
megawatts is just bonkers. no way will this ever be safe as this fleet ages.
Some drink at the fountain of knowledge. Others just gargle.
Having installed one of the supercharger locations I can tell you that they are not exactly light weight on the power. Each charging cabinet was fed with 480Vac @ 175Amps, 3 phase. About 145KW. Each cabinet had a pair of chargers. The units were water cooled too. Pretty nicely engineered affair to be honest. I really would not want to put my car on one of the V2 units, Lithium batteries prefer to be charged at a more sedate rate. I can only imagine just how bad the V3 would fuck them up!
Good thing no one is talking about 250 kilovolts, isn't it?
Can I build an arc welder to plug into it?
I've abandoned my search for truth; now I'm just looking for some useful delusions.
Please convert miles to hogs heads so the metric community can understand.
Pretty much, although I'd much rather have 600 miles in 15 minutes, your scenario would at least be useable.
Too bad you'd be riding on rocket fuel. Fuel and oxidizer packed in close proximity is something we didn't push too hard on in aviation on account of it being too dangerous for everyday use and tremdendously mass SWaP inefficient compared to liquid fuel powering an air-breathing engine. But suddenly you want it in your car.
So this is only an issue for Tesla.
well, if you're recharging it with gasoline; the future is now buddy boy!
Yep - shot into space at 1000 mph.
Nope. Ignoring air friction, and assuming you shot straight up, the highest altitude you'd reach would be a little over 10 km before you'd start falling back to earth. (v^2 = 2ah if you want to check the arithmetic.)
If it weren't for deadlines, nothing would be late.
V2 vs. V3 charging
The charge time to 50% charge really is close to half that of the V2 charger. I suspect future SW updates will optimize this somewhat further.
Given that for some one going from 0 to 100%, the net savings will not be some eye popping number. But for those who drive in with 30 miles on the battery and fill 200 miles per session might see significant savings, from 35 minutes to 20 minutes, may be.
But the real winners are the yet to be made pickup truck and the roadster. Their battery capacity is very high and they can soak up power at 1000 miles/hr for 15 minutes or so, picking up 250 miles in 15 minutes.

Finally, a Tesla product I really want to try.
Teslas with Autopilot are so safe they don't need bumpers.

Fortunately, Tesla only tests their cars on nice sunny southern California days, so there's no risk of injury.

Do what other municipalities did to coin miners. Raise the cost of high volume electricity to that consumer.
If you're going to slam the grid, you get to help improve it.
I actually think Tesla has made the right tradeoffs. I don't want to carry around a 600 mile battery... Why do I want to carry that much weight when my average day is 40-100 miles? When the energy density gets that high I'd rather have a lighter car that can go 300 miles. Getting the 15%-75% charging times down is the right thing to do for people who are on a road trip, so I see the V3 as a great move.
One of the reasons I got the LongRange battery in the Model 3 (besides that it was my only choice at the time) was that I knew from previous experience that I would take a big hit on range in the winter. So, the "310" rating gets me a good reliable 200 miles in the dead of winter, and more like 260-280 in the summer going at "normal" highway speeds.
If I lived in a warm place like Southern California I'd consider the small battery, not having to deal with the cold weather issues. Again, as long as the Supercharger network is dense enough to get me from city to city, I'd rather have the smaller (cheaper, lighter) battery for everyday driving than some humongous battery that I almost never use the capacity of...
The key to the Tesla in my mind is the Supercharger network... Most of the other charging infrastructure dates back to the days of crappy EVs with tiny batteries that were only used around town. We use the Chargepoint network for our old Honda Fit EV and now for the Volt, but never for the Tesla. The Tesla has enough range to never charge when out and about... and the Chargepoint network is more of a destination thing... you charge when you get to your destination, it's not really convenient for along-the-way charging the way the Supercharger network is.
When the other automobile manufacturers get serious about selling EVs (we're still 5 years away from them WANTING to sell you one instead of an ICE) then maybe some of them will partner with Tesla on the Supercharger network. Or maybe Tesla will spin the Supercharger network off as a separate corporation?
