No more live batteries Ultra-capacitors!




by caracole » 13/08/08, 20:48

Someone knows this product

http://www.colemanflashcellscrewdriver. ... nformation

Do not use a battery (it's good for ecology) only an ultracapacitor.

Charged in 90seconds and much more autonomy than a "conventional" screwdriver

I looked vain, I did not find this product in France, Spain.

Uh ... bcp more than a classic battery I doubt a little anyway ...

Otherwise the electric screwdriver is not bad as a product anti-econological you do not find?

A screwdriver I say no ... we all have one but that ...

It is totally true ! we are no longer talking about a capacitor in micros-farads, but ultracapacitors, ultracapacitor whose value is expressed in Farads .... It's not nothing. and in a few years, I think these products will replace the batteries.

A look here: http://www.ultracapacitors.org/ultracap ... ducts.html ( in English )

and here (in french)

In a few years I do not know but now ... Here's a topic on the question:

ultra capacitor

What do you think of this? It would be good if it was not just an announcement effect a revolution in perspective.

: Arrowu: Your niouze is not very cool ... It dates from August 2008. :?

The body of this car Microcar, manufactured in France is sold in Canada or receives its electric motor.

Eestor technology has not been proven yet.

Finally do not believe that it will be easy to recharge at home in 5 minutes ... For this it will be necessary to have at home a charger rather expensive ...

ultra capacitor




by raymon » 04/05/09, 07:12

The main interest is not that these capacitors that allow greater autonomy would have a much longer life, are almost indestructible, could be recharged very quickly on a suitable electrical outlet, would not be limited not the possible shortage of lithium.
400km range and 125 kmh it's not really a cart.

... and the meter connection able to support the demand: it must do a lot of amperes : Cheesy:

In fact, I think the 5 minute connection could be a "gas station" service, which is a good time to get home without having to push. For the rest, we have plenty of time.

There are still some problems with recharging, which is a security problem (theft, vandalism and others) when you do not have a garage: imagine that you had to recharge your batteries at the bottom of your HLM in a neighborhood " sensitive ": it would be better to go to the gas station.

Or take out the ultracapacitors one after the other to get them to the apartment (pray for the elevator to work) and load them ...

On the other hand, the big big advantage is the charging intensity. While the batteries do not support a load greater than 3 times its capacity (that one corrects me if I am wrong on the 3C because the medocs that I take currently disturb my memory and my reflection).

Off in deceleration with engine braking, if we want to recover the max of energy we will necessarily exceed this limit. In the case of supercapacitors we are not limited. Moreover for the restart we can draw more power than for a battery.

At first, I think that the supercapacitor will be put in parallel with the batteries for energy recovery to restore the power at startup and to recharge the batteries at a power acceptable to them.
