Good point, but even lossless, you've got to push power in at a rate above 1 MW.Another Ooof would be to get rid of 120kW excess heat. Here is hoping that charging a supercapacitor comes with way less losses than batteries: moving electrons instead of ions.
What would be a reasonable rate to expect in the future? Is the superchargers' 120kW already pushing it? Assuming batteries/capacitors are not the issue.Good point, but even lossless, you've got to push power in at a rate above 1 MW.
Unfortunately, according to Wikipedia (which appears slightly out of date at the moment) current supercapacitors only have about 1/50th the energy capacity per kg as Li-Ion. The new graphene supercapacitor in this video could bring that up substantially, but I couldn't find any numbers that indicate its energy capacity per kg. It would have to be in the 100-250 Wh/kg range to compete with Li-Ion according to the article.I'm assuming super capacitors of a comparable power - say 85 kWh - would weigh way less than the equivalent amount of batteries. If the Model S is somewhere around 4,600 pounds, how much weight savings would super capacitors provide?
Not only would that extend range, but it might cause a total redesign of the car.
Ya, that's why I passed on buying the Roadster because the Model S battery technology was going to be better!A friend just sent this to me and said "Your car is already out-of-date" lol.

And it should sound like the Death Star powering up when recharging after the Model S leaves.Wouldn't the solution be to load up a supercapacitor at the supercharger station with 85kWh of energy and then when a Tesla Model S plugs in then the power is dumped from the charging station's supercapacitor into the car's supercapacitor?

So almost like a "battery swap" where you don't do a physical swap you just swap the power in one supercapacitor into another.
The charging station's supercapacitor has to be large enough to act as a buffer or cache so that if there are a lot of cars in a short amount of time they can all get a super super super fast charge.
