Interested to learn how the "wall box that will allow high speed charging at home" will work given the restricted amperage of the single phase feed to homes?
Most modern US homes have 200A service at 240V (which is center-tapped, with the center at ground, giving us two sets of 120V circuits that are 180 degrees out-of-phase). So in principle, a 48 kW charge rate is possible. Of course, that would leave nothing for the rest of the house.Interested to learn how the "wall box that will allow high speed charging at home" will work given the restricted amperage of the single phase feed to homes?
My best guess is that it will be a very big "wall box" incorporating a large battery pack which will slowly charge from the incoming power line .... or is there another way?
Most homes in the UK have only a 60A service fuse at 230V which gives a maximum of just under 14kW - by the time you subtract the power taken for cooking, lighting, entertainment, etc. only a "slow" charge is possible during the evening (more in the "wee small hours", but still not what I would say is enough for a high speed charge without battery assistance).Most modern US homes have 200A service at 240V (which is center-tapped, with the center at ground, giving us two sets of 120V circuits that are 180 degrees out-of-phase).

I do not know what modern homes in Germany have.
I guess we should also ask them exactly what they mean by "high speed"?
Coolest car there?
I really like the idea of one motor per wheel, but it needs to in-board. Putting it in place of the normal wheel hub and brakes increases unsprung weight by a lot, which is terrible for both ride and handling.https://cleantechnica.com/2019/06/20/evergrande-group-says-it-will-be-major-ev-company-in-3-5-years/

The linked article does't mention them. They're great at providing or absorbing big bursts of current, but their energy density is way too low to replace batteries for bulk energy storage.Super caps here we come with regen almost instant charges.........

Actually that's a pretty big deal IMO. Certainly not continuous cruise power, but assuming you get that rate for 6 hours a day, that's 45 miles/day range from onboard solar, which is never plug in territory for many daily commutes. You won't always get the sun, but when coupled with 450 miles of battery to buffer against inclement weather and to cover the occasional longer trip... very interesting.Be still my beating heart!
The solar panels add an additional charge of up to 12 km/hour (7.5 miles/hour).
