Tesla launches '1,000 miles per hour' charging station for Model 3

Chevy had the Volt, it failed, now they have the Bolt. The Euro automakers will build and sell to the luxury end of the market. The only competitors in the mainstream US market will be from Asia, mostly Kia and Hyundai. AFAIK, the largest selling EV in Europe remains the Nissan Leaf.

From what I’ve read 90% of charging is done either at home or at work when there is plenty of time.

The biggest advantage of a charger over a gas station is that a charger can be put anywhere and it’s much less expensive.

[Moonman62]

The last 20% of charging is slow. If people can make do with an 80% charge, they can do it in a time that’s tolerable for most people (with the new V3 Supercharger).

[Moonman62]

When the big European,Asian and American car companies get up to speed (if you’ll pardon the pun) on electric vehicles Tesla will just become another Studebaker.I’ve read that Chevy already has an electric vehicle with the same range as any Tesla and has a sticker price $10,000 less than the cheapest Tesla.

There’s otherwise an overheating problem; better regardless to “top it off” rather than to deep-discharge the batts. And better to just have a 220 charger in the garage.

Surviving winter with a Tesla

Will the computer on a Tesla allow the batteries to be deep discharged to the point of doing damage?

[SunkenCiv]

I doubt it. Mostly the concern is, keeping drivers from running the batteries down too low to reach any place where the car can reasonably be recharged. That's just smart marketing. But the charging will slow down if the batteries get to some specific temperature, but also to protect the charger itself. As the root article for the topic notes, these new model Superchargers have a cooling system for the cables.

LOL

[Moonman62]

There’s a new software update that will start to heat the battery as the car approaches a Supercharger, so that it will be at the optimum temperature when the charge starts. That will shorten charging time.

The onboard computer should also prevent any damage to the battery from discharge or overheating.

One of those vids was supposed to show a guy struggling to charge his Tesla at home, parked outdoors in the winter, using only an ordinary baseboard receptacle. 110 v current can barely keep the car at *current* levels in extreme cold. :^) Anyway, not sure if that's the right one or not, this computer won't stream.

[Moonman62]

I would say that guy is the exception, not the rule.

I don’t think a person should buy a Tesla unless they have a garage with a charger, or a place at work where they can charge.

I can see a day in the future when people with neither can have their car self drive to a charger when they are asleep or otherwise not using it.

[SunkenCiv]

I'm all set, I've got a 220 outlet, all I need now is the car. Oh, and to clean that stall of the garage. No need to be hasty I guess. :^)

interesting calculations, but limiting the voltage to.240 volts is not honest. Commercial grade power can be had at 5000 volts or more to a industrial power panel. go outside look up at any power line count the number of ceramic insulators each averages 10000 volts in insulation capacity. typical three phase AC service in the USA at the street level is 15000 volts to the grey transformer on the pole. These 250kw operate at 500 volts or more there is little reason not to go to 1000 or even 5000 volt charge connections. they are only energize once a complex triple redundancy safety protocol between the charger and the vehicle have been met. there is zero risk of electrocution from a modern digital charge station to carry 5 megawatts at 1000 volts is 5000 amps and at 5000v it’s 1000 amps. 1000 amps is typical start current to the starter motor of your ICE car open your hood look at the wire running to the starter that is taking 1000amps at 12v to start your car not for more than a few seconds but its not arm thick cabling. 1megawatt chargers are coming they are inevitable. I take 10 plus hour road trips 5 or more times a year. my car has a 650 mile range which is twice as far as my bladder and backsides will take in one sitting at 300 miles I stop to strech ,piss and eat all of which takes longer than the 25 min it would take to add 300 miles to a tesla. 300 miles is 5 hours at a avg 60mph good luck getting that anywhere other than west Texas even with 75mph speed limits traffic always limits the avg to under 60.
