Supercapacitor News

I suspect that a vehicle powered by supercapacitors would be charged by other supercapacitors, and the charging conduit would not be a 2" diameter cable but instead a large number of conductors that connect underneath the car. The supercapacitors on the charger side would provide the power storage necessary to do a quick charge, while the multiple connections under the car would provide sufficient conductors to allow large current flow. The charging side supercaps would then be charged at a slower rate via a connection to the grid.

I could see a charge like this taking about 2 minutes, perhaps faster.

Imo an improved energy density and not needing to charge slower from 50% to 100%. Is the way forward. Wether this is by a combo of capacitors and batteries or a standout cap/bat I don't know.
One of them will win in the end.

This page goes through some basic concepts about capacitor charging/discharging that might apply to supercapacitors too:

Considering the huge corrent that an 85 KWh supercapacitor needs to be charged in 16 seconds what about an AC to DC converter to charge up the supercapacitor?

Sorry for the naive question, but would it be possible to charge a traditional battery pack with super-capacitors? In other words, could I slip a couple capacitors of some form into say a frunk slot or two and then be charging my batteries over the next 10 minutes as I drive away and the capacitors "unload" into the traditional battery pack?

I always envisioned the next step being sort of a charge-as-you-drive solution that can be swapped out like one would exchange an empty propane tank at Home Depot. Essentially a charged capacitor to do the job of a fuel cell in a vehicle, but much cheaper and not requiring the step of turning the electricity source to fuel and then back to electricity in the vehicle.

Cool! Very interesting. IMO the charge-as-you-drive idea is good. Hope that Tesla will consider this idea.

I can swear I saw a Tesla patent somewhere on this forum for just that. I beleive they are on it.

That is how the current Superchargers work...

Good. I would love to see a 110 KWh battery + 110 KWh Supercapacitor Supersport AWD Model S P+++. (This would be really cool ). Maybe we would have a range of 700 mi?
