Thats a non issue.

You tell that to competent electric engineers, specialized in high power currents.

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!).

Well, that is called the basis of a de facto standard and if no one else will step up and propose something, it might as well be his organisation...

Wow. 1300A?

And how many vehicles per hour?

Frankenstein (over the Service Station tannoy): "Quick Igor, the ultra-capacitors are at their height!"

*Igor, wearing a welding mask, throws a lever.

Frankenstein: (mad gleam in eyes) "Give my transportation life! LIFE! Bwwwaaaha-ha-haaaa!"

*lame sound of electrical whine reducing in pitch.

Frankenstein: What??

Igor: Maastah, thith ith the tenth car thth morning. We musth shut down the syth-tem and await the recharging of the capacitah bhanks.

Frankenstein: Noooooooooooo!

So it would matter if the proposals are filled by no-bid-contracts and there are open source specs so any manufacture can make aftermarket bits that owners can buy.

Well, if public money is being spent in the EU it has to be through a tender.

But I agree, an open standard is preferable, but a de facto one is better than a free for all.

I shall be at the Motor Show on Saturday. I intend to visit their stand and the quick charging question will definitely be at the top of the list.

ABG has a bunch of pics. It definitely seems to move under it's own power.

As for fastcharging, that recently tested 2Mw could fill up a Lightnings, or whatever, all day long. 3 minutes seems a bit fast though. Most articles state 10.

domenick!

Thats exactly what I meant!

A open source technical solution - not stumbling from oil addiction to the next one - to a setup of a shrewd scam setup of a non-open standard battery vendors monopolistic pos system.

Thanks for the link

Those pics are from the company website gallery. (Press Area)


The AN battery clearly works, but reading between the lines it would have been connected to the grid through some heavy cables.

Most articles state 10 minutes for a full charge, but 3 minutes for 80% is what is driving this high current.

Are there any better interior shots?

OK so I had a bit of a think about this cable requirement and came up with the following. Maybe someone can check the maths.

Based on a typical 13A cable having cores of 1mm diameter, I recon you would need three cores of ~27mm diameter for a 3 phase system (I'm assuming UK 415v three phase here). Not including insulation, that means a 77mm diameter overall cable.

Taking the density of copper as 8950kg/m3, that leads to a cable mass of 15.5kg per metre, plus insulation.

Not out-of-the-question heavy, but certainly very unwieldy. Think of an F1 refuelling hose.

No idea how much difference braided cable makes to this, and this assumes 100% efficiency in the charging for the assumed supply current.

dp,

it's a beautiful looking car for sure... I hope that the handling and performance is just as good.

BTW, do you have any idea how much those wheel motors weigh?

All the best,

Chris H.

Someone can gladly check my math but I did some calculations on the first post on autobloggreen on the Lightening, I'll quote:
"OK lets do the math then.
The battery pack is 36kWh, and it can get to 80% they say in 10 minutes. So assuming you've completely drained it and you want to recharge it. You then need to supply 36 x 0.8 = 28.8kWh. Lets say there is a 10% lost to inefficiencies in the charger. You then to draw 28.8kWh x 1.1 = 31.68kWh from the grid. That is over a hour to full the battery but we only have 10 minutes so we are talking 6 times as much power. 31.68 x 6 = 190.08kW continously over a 10 minute period.

I must admit I'm no expert on 3-phase power but it seems our normal industrial 3-phase and 3-pins or 4 pins, IEC 60309-type connectors has a maximum of 690V and 250A, which gives you a max for the plug (and probably the wire as well) of: 690 x 250 = 172kW.

So you are talking special extra thick industrial type plug. And that is just the plug, the power needed is so much you probably need a dedicated feed from a powerstation. All this means for someone to be able to do this they will be paying a LOT more than the basic rate for the kW you pay at your meter. Hence the economics of the quick-charge means it will hardly ever be available."

Sounds to me as 10 min charging is not effectively possible. And the range is NOT 200 miles, probably 200km. Tesla's choices are looking better and better every minute I'm actually pretty sure for the Roadster they hit the exact right choice. For the model S it might be different with the shortish shelf life of standard Li-ion but we'll see I guess.

From various info on the PML Mini, the entire wheel assemblies are apparently 24kg with the motors and 23.5kg stock (including disc brakes etc).

Look to the left of centre in the pictures and you can see Messrs Siry, Rochefort and Platshon checking out the competition. Boys, stop looking so shifty or you'll give the game away :-D


By the way, am I the only one that thinks this has a hint of Fisker's pen about it?

Those images are way too big to place inline on this thread. Can you find smaller ones and link to the larger ones? Or just leave a link with no image.

Btw, Notice Darryl and Aaron in the background?

Yeah, as soon as I saw them come up I replaced them with thumbs, but you beat me to it :redface:.
