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.

my answer and the death ray plasma arc

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.

Re:Catching up

[JaredOfEuropa]

Meanwhile, existing Tesla hardware is already capable of utilising the higher charge rate after a simple software update. That’s pretty impressive. I don’t think any of the other car manufacturers had the foresight to prepare for the 350kW chargers or even the 175kW ones. Sounds like they are playing catch-up to Tesla, not the other way around.

Re:My car needs a software update

[olddoc]

I think the hardware will be a big reason why Tesla cars get scrapped. What happens 15 years down the road when the motherboard that controls the charging system blows a capacitor and Tesla says they aren't made anymore? Will there be an aftermarket supply of major electronic components for old Teslas?

Re:WTF is 1000 mph charging?

[AmiMoJo]

MPH for charging speed is a very useful metric, because it tells you how long you will have to charge to go a certain distance. If your destination is 200 miles away and you charge at 400 MPH, you know that you need to charge for half an hour.

The main issue with it is that it depends not only on the charging speed, which varies with the battery charge level, temperate and a number of other factors, but also the efficiency of the car which varies with model, tyres and most of all driving technique. 1000 MPH is the most optimistic figure, if you drive the car hard it will be lower.
