LOL. Do these people even think for just a second or two about the implications of their claims? What kind of connection from the grid are you going to have to have if you’re going to be able do dump that much power through an outlet “in seconds”?
And fusion power, cheap and plentiful, is just 20 years away (or was it 10?) forever....
It’s obvious the writer is conflating the ability of the coin sized cell to be charged in seconds with cells that would be the size of a D cell and thousands of them in a EV pack.
While the coin sized cell with maybe 1500 miliwatt hours total capacity and that is being generous could be charged in a second with 5400 wattseconds of energy which at 3.7V would be 1459 amps over a single second at 5 seconds it’s one fifth the amps 249 over ten seconds it’s 145 amps and so on for each doubling of seconds.
To do a 50kWh pack in ten seconds would be 18,000,000 wattseconds or 18 megawatts for ten seconds at 1000V HVDC V4 standards you would need 18,000 amps.... For more reasonable 5 min which is 300 seconds you need 600,000 watts per second a much more reasonable 600kw which at 1000 volts is only 600 amp the Tesla NACS plug is rated at 900 amps and 1000V with a coming extension to 1000 amps and 1200V. So charging a Model 3 pack from zero to 100% if the cells could take it would take 5 min at 600kw well inside the V4 HVDC standards.
No way a car sized pack charges in seconds not unless you have have 25,000V HVDC distribution grid voltages at long distance 500,000 volt HVDC powerlines volts 18 megawatts is only 36 amps the conductor could be shoestring thin the insolation would be subsea cable thick think half a foot wide cables and 25+ lbs per linear foot. Not happening I like my Model 3 very much but be realistic. This writer doesn’t know engineering electrical or otherwise.
