Oh dear Lord. They're going to paint the hub motors in bright colours, aren't they. Just so everyone notices.

Looks like blue LEDs to me. I think it's fine for an auto show.

Hmm, they are just not getting this quick charge business are they.

So unless I am mistaken, even on UK three phase, to charge the Tesla battery in 3 minutes would take 2000 Amps. The Lightning will be no different, lithium-titanate battery or not. I doubt if Tesco or any other store has that on offer.

This in the trunk, anyone?

Finkenbusch

If a supercapacitor is (slow loaded and) put inbetween the carbatteries & the grid (wether at Tesco or at home) to empty 2000 Amps in a very short time from a condensator to the battery are not unfeasable.
As capacitors main purpose in life is ultra fast up-unloading of power.

And high capacity capacitors are no future items but today in daily heavy use in many public transport systems all over Europe, and I suppose the whole world.

"bitchslap Tesla"


ha ha Tesla is the one to beat.

Tesla should address the quick charging thing officially. They have publicly commented that the Roadster could charge in an hour. I'm sure it's too late to change the 2008 car so it could actually do it at a high powered charging station (Tesco) or whatever, but I think hat they should say that they could do it and will offer that capability for the 2009 model. Nevermind that it will rarely get used by Lightening owners or Tesla owners, Tesla just can't loose the bragging rights fight.

Because the consequeces would be what exactly?

If they indulge into this stupid quick charging charade they will only add credit to it. They should stick to ther "charge over night" and point out the difficulties when confronted. To handle megawatts of power the major issues are cables, safety and reliability of connectors.

Tesla should put out an official press release, or at the very least a blog entry on their site, debunking the whole quick charge thing and put some science behind it.

They especially need to do this if they plan to go down the battery swap route with future models. Maybe they could put it out jointly with Project Better Place.

Finkenbusch

Thats a non issue.
With that weak security concerns nobody would be allowed to fill any vehicle with a highly flammabe or explosice agent as petrol or gas in public places.

Its a matter of technology only.

And that technology (bring high power outlets to the masses in tghe US like we have in most over Europe) is here today - only hindered by the lazyness of the fat & n the brink of bancrupsy waggeling US car (and other industries) industry on one side and powerful interests to keep the status quo as oil addicted (look in your wallet after paying at the pump)


To be on the cuttiong edge of technology was once a USA trademark - lets stick to the spirit "It can be done"

Finkenbusch

If you look very close under the skirts and in the pants of "project better place" you find out that is a well thought and well maketet (till Olmert in Israel) scam - to lure the public with a shrewd green argument from one dependency (oil) to the next (one single monopolistic battery producer, marketeer & technology!).

Think - the proponent is a very clever SAP official - he knows ho to trick markets / investors and mislead the public.

Better go forward and confront the future with the best the US historical proven has - intelligence, cleverness, open market thinking and technical prudeness.

Leaving the oil chains behind forgood...

dpeilow

I think you are missing the point. At 415v this requires 2000 Amps. Their plan can only work with 11kV at the outlet and that requires massive re-engineering of the grid, whether in Europe or the US.


But hang on: Welcome to Lightning Car Company - The UK's Premier Electric Sports Car

OK so maybe 1300A
