Could someone please explain to me how this is possible ?

NO NOT at allPractically, its not possible because every battery takes time to recharge for 1 hours or more time. So, this range would be a myth.
Some background (here)... Fisker is one of those companies you love or hate (especially for Tesla fans)... time will tell whether any of these claims are 'real'... personally I hope they are, we really need a step change in battery storage capabilitiesCould someone please explain to me how this is possible ?
And just think, nothing is 100% efficient. The inefficiency primarily presents as heat. If the process were 95% efficient then you'd have about 750 kilowatts of heat generated over the course of 1 minute. That's a lot of heat. It's equivalent to burning about a quart of gasoline over that one minute interval. To my knowledge charging tends to be ever worse than 95% efficient so the losses only increase from there.It's not possible
It's Fisker - the well known con
700 miles range is what 250 Kwhrs? - in one minute is 15 Mega Watts
At 1000 volts that is 15,000 Amps
And that is assuming zero losses!
It's a con from a known con man
Playing devils advocate, Tesla are already claiming 1.6MW on the Semi using an 8 pin charge port (here)... are we really saying that Fiskers claims are *impossible* or they are simply beyond anything that we can imagine today700 miles range is what 250 Kwhrs? - in one minute is 15 Mega Watts

I'm not sure what you think a "Truck Sized" connector looks like, but the 1.6MW connector fitted to the Tesla Semi is about the size of an adult male palm (see photo), indeed it's smaller than most CHAdeMO plugs that I've usedTesla already do what 300 Kw? with two pins so eight would do about 1200Kw
Sounds doable - but that would be a "Truck Sized" connector
Do you think Tesla has actually charged a Semi at the claimed rate to the claimed capacity with this connector (or any connector)? Since the current prototype is for show, with specs that are generally phrased as characteristics of the truck which will exist in a few years, and many technical details are deliberately not mentioned, I suspect that the connector is "conceptual".I'm not sure what you think a "Truck Sized" connector looks like, but the 1.6MW connector fitted to the Tesla Semi is about the size of an adult male palm (see photo), indeed it's smaller than most CHAdeMO plugs that I've used![]()
Who knows? If you start doubting what Musk says then what about the rest of the semi or 2020 Roadster announcementsDo you think Tesla has actually charged a Semi at the claimed rate to the claimed capacity with this connector (or any connector)?
I find it hard to imagine how you could physically plug one vehicle into four Superchargers, the cables are short and most sites have the charging stalls in a rowThere is a rumor about, that some months ago, a Semi used a group of 4 Superchargers at once for a recharge.
Extension cords?I find it hard to imagine how you could physically plug one vehicle into four Superchargers, the cables are short and most sites have the charging stalls in a row![]()
It's a long way if it consists of conductors which are too small. It's not unreasonably far for properly sized 400 volt power cables.Whatever you believe, it is interesting to consider the length of DC power conductor used in the Tesla Supercharger architecture. Conductors travels from the bank of chargers in the Supercharger cabinet, across the forecourt, in/out the Supercharger 'stand', into the car, through the HVJB, and then finally into the battery... that's a long way![]()
Sure... thankfully we don't have to guess at the Supercharger site details because they're available online (here)It's a long way if it consists of conductors which are too small. It's not unreasonably far for properly sized 400 volt power cables.
Sure, why not, it's only 120kW DCExtension cords?
