Don't get me wrong, I'm all for this but I remember reading a comment on here a while back saying that to get that kind of energy jammed into a battery that quickly you'd need a cable as thick as a telephone pole to keep it from glowing like a toaster coil.
Nah that's bullshit.
Interstate powerlines are like half an inch and they carry several orders of magnitude more power than you'd ever need to quickly charge a car battery.
EV charge cables are thick because a lot of them contain several wires which all need to be electrically shielded from each other (which is generally done by maintaining a physical gap between the actual wires). Part of that is just because we have multiple generations of EV charge technology and the new standards are backwards compatible with the old standards... so a lot of the wires in the cable are not even used when you charge your EV.
Yes but that's 10s of thousand volts AC power at a reasonable current. We're talking DC at a couple hundred volts and an extremely high current.
