Can you stop fucking pout pout in all the topics of electric cars that there is on this site and focus on your already started topics which already discuss it too widely with no evidence to support!
It becomes heavy in addition to destroying the real subject!
Experience the electric car

Alain, could you stop taking yourself for the schoolmaster?
And in addition interest you to read the posts? Is it me who talks about telecom and lobbies?

When on the subject indicated, I am still looking for reports showing real and independent measurements showing the energy consumed for recharging car batteries, in correspondence with the energy then released at the input of the engine.
It seems that for several decades, no specialist or journalist has thought of making these measurements? Surprising, isn't it?

This subject speaks of feedback from the electric car, so this is not a discussion on the pout pout!
Stop rotting all the good stuff with your gadget in the air!
Even Christophe asked you but you still persist!
I invite you to read your own comments> 90% of your 1595 posts are to promote pout pout!

Stepping behind sometimes can strengthen friendship.
Criticism is good if added to some compliments.

Indeed, you speak of that, with a vocabulary of school lessons, citro speaks of telecom and lobbies, while I ask:

As a great specialist in everything, have you ever seen a measurement report on this?

You take yourself for Christophe now, do you think he's not big enough to speak when he wants?

Another of your free affirmations, because you know everything and you control everything, even the percentages of my post speaking on this or that subject? surprising
Come on, laugh, show us your seriousness by showing how you get to 95%
But start a new subject, there you pollute.

well I see that there is nothing to do and that we are scrapping hard on this forum...
to respond to citro on the use of batteries, i quite agree that lead is a solution that is old and heavy. Unfortunately lithium is still emerging and not very economical especially if we want to make a low cost car capable of doing most of our daily journeys, ie 70km.
So why not keep these good old batteries and instead focus attention on the lightening of the car in question.
10kW of lithium batteries costs at least € 4000, which is still expensive, whereas with lead it is 5 times less.

I agree that the more technically simple the solution, the better.
But the laws of mechanics being what they are, it takes more material to make a vehicle around something heavy. This is summed up by the "spiral coefficient" studied and presented by Michel Kieffer (whose site no longer works ???).
So when you understand all this, you are looking for another solution than batteries.

You can give an example for lead batteries at this price.enzo20134 wrote:10kW of lithium batteries costs at least € 4000, which is still expensive, whereas with lead it is 5 times less.
I have the impression that you imagine being able to use automotive starter batteries to ensure the traction of an EV ...
Electric traction batteries have NOTHING to do with the automotive batteries found in supermarkets ... They are much heavier, and above all they support "deep discharges" at 80%, when the starter batteries support painfully 10% discharge ...
With starter batteries, of equivalent capacity to the NiCd batteries which equip my cars, you would painfully obtain a quarter of the nominal autonomy (20km) ...
With good lead traction batteries cars like my 106 painfully reach 50km. My current autonomy at NiCd is 80km ...
In short, lead-acid batteries worthy of the name would cost you at least € 3000 with greatly diminished performance and a lifespan of 2 years maximum in daily use ...
There is no photo, lead is not economical ...

a lead type traction battery does not cost more to manufacture than a starter battery and weighs the same weight
the problem is that these batteries are less common, and even worse called special solar! therefore more expensive only because of a coup
basically with lead we have 2 times less energy for the same weight than with NiCd
but secondary problem, with the NiCd one can empty until the end without damaging the battery ... with the lead if one empties until 0 without reaching an outlet the battery will be damaged while awaiting the load: it is for what the lead battery finds especially useful next to a heat engine, not alone
there may be better, the NiZn battery, it has already worked, it does not cost much, it has known drawbacks, but as it is I think it will be useful!

Eco Marathon (s) 2011
Hello
In 2011 the IUT Ville d'Avray will take part in the challenges
** EducEco (all electric and solar)
** Shell Eco Marathon (all electric, on 17 cars entered)
see website http://shell-eco-iut-va.voila.net/index.html
(especially The News)
Personally I actively participate in electric motors
Do not hesitate to support us
Competition will certainly be formidable!

It is possible that I participate, as last year, in the supervision of the event.
So we may meet in Nogaro.
I wish you less "stunts" than in 2010 and more success.
