Well, if you could tap a 1000 Volt line you could use a smaller cable. I don't seem to have any of those near my house. Maybe underground, I don't know.I was thinking about the same thing. Assuming a Tesla sized battery, charging in 5 minutes instead of 75 means drawing 15x the power.
I'd priorize the battery issues as follows,Yup. The issue with EVs right now is energy density, not charging speeds. The charging speed issue is already being addressed, so now all we need to do is increase energy density by 3-4 times.
Agreed, but think about power stations (aka: gas stations) that had access to that type of high voltage line. Then you could drive your EV without any range anxiety since there could be a station on every corner like there is today with gas.Well, if you could tap a 1000 Volt line you could use a smaller cable.

I think we all get that. My comment is simply that to deliver the same energy in 5 minutes that a Tesla gets from a supercharger in 75 minutes the charger has to deliver 15 times the power.If you read the article about this new company, they are not talking about charging your standard LI battery faster. They have developed a new battery technology with the primary goal being fast charging. It looks very interesting!
I''l jump into the could be wrong pool. My understanding is that our neighborhood (fairly typical modern) has a "low voltage" or "mains voltage" supply of 1kV to our distribution transformers which step it down to 240V split phase.The line that distributes power to a neighborhood is 2400V (correct me if I'm wrong)...
4000 amps 1200kwA 5 minute charge on a 300 mile battery, as claimed, would take a lot more current than is available anywhere people are currently charging cars. I imagine you would probably have to build charge stations that are next to and tap directly into an electric company distribution substation. These new batteries are still going to be slow to charge when charged at home, work, and most convenient locations. But it is still nice to see advancements here.
