The potential to significantly reduce pollution could be huge.

Toyota boasts new battery technology with 745-mile range and 10-minute charging time — here’s how it may impact mass EV adoption::The potential to significantly reduce pollution could be huge.

    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. Go have a look at your nearest interstate powerilne. They transfer enough power to power, well, an entire state or at least a significant percentage of a state, and a lot of them are as thin as 1cm (less than half an inch).

      If you can power an entire state off a cable that thick without any issues, you can obviously charge an EV quickly with a very thin cable.

        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.

          Yes - cables do get thicker as you increase the capacity… but you’re never going to see a cable as “thick as a telephone pole”. Any vehicle that needs that much power will use hydrogen instead (Airbus plans to have hydrogen powered commercial passenger aircraft operational within two years).

          The other thing that needs to be considered is distance. Those interstate highway lines need to carry power over extreme distances. An EV charge cable can be very short (and they could be a lot shorter than they typically are, if thickness were to become an issue).

          There are already 350kW DC fast charge systems in deployment right now and the entire bundle of cables (several wires) is about as thick as the cable we’re all used to for pumping gas.

          At 350kW you could charge a small EV battery in something like two minutes. In reality, it takes longer… because current battery tech can’t take that much power on a small battery - it can on very large batteries such as commercial heavy vehicles, but hopefully that will change soon.
