Capacitors? Where's the proof?

Now what could cure all of this debate would be for battery companies to start making 12V batts that rest at 14V, narrowing the gap between alt and batt voltage. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

Noobs will still buy caps.

That gap is there because you need a higher voltage to charge the batteries. If your batts rested at 14V you would need 16-17V to charge them...

Actually it would be 'technically correct' to put it like this.. once they discharge they are going to pull demand on the system rather you have it or not..

Still not technically correct...once the cap is initially charged it merely floats along with whatever the system voltage is. It doesn't draw any extra to speak of at that point. Unlike a battery that can supply a relatively large amount of energy before its voltage drops appreciably, a cap's voltage will drop at a constant rate as energy is drawn from it. Technically, once charged to system voltage, a cap is always charged fully.

Some things to think about. The vast majority of the energy stored in a cap is not usable, ever. It might soften the initial voltage drop from the alt being overloaded or give the alt the mili-seconds that it needs to overcome its own inductance and increase output during a transient but as far as providing a real storage capacity for system use, even the biggest caps are useless. A cap with zero ESR (the perfect cap) has a usable storage capacity of 0.5 amp-seconds per Farad. Even small batteries measure their storage capacity in amp-hours. You would have to completely fill your car with caps to begin to rival the storage of even a small battery. Also because caps do have an ESR, the more current you try to draw from one, the more voltage is lost as heat. In a high current demand situation, a cap can be rendered completely unable to deliver any current because its output voltage is dropped to system voltage by resistance losses.

No offense to you, because you are learning and none of us started off knowing everything, but like helotaxi said, your understanding of how caps work is very misinformed. If you have any questions on what Ive said here, feel free to ask.

i do have a question.. why are you being such a small minded idiot about the electronic characteristics of capacitors?

is it because you have learned some 'advanced' pieces of knowledge and can no longer provide to the community because your theories are out-dated?!

i'm thinking that is exactly what is going on.. otherwise you would be worse with that much energy to derive the science of the technology.

you sound like you are talking about technology that you have read from books that go back to the era of 1960.

to argue about what i said on how each event a capacitor goes through has a name for the characteristic.. you are making yourself into a troll and a flamer.

your efforts will not continue to mislead the people now that this post has shed light on your illicit methods.

by taking whatever characteristics you want to derive a capacitor that fits your needs is pathetic and doesnt justify the science of the technology as my original post does.

"then the cap has to recharge it self by ******* like a vacum all the energy it can from the battery"

here you bother to contradict yourself.. giving an example of hypocrisy.

one post says they arent patient.. another post says they are patient.. i think it is you who is ruining the sticky.

The underlined statement is false IMO. If you have a big bank of 3100's with a single 300a alt you can easily run 10kw+ depending on how many batts you have.

You are correct, in a way. Eventually your power would run out, if you played forever. But no one does, and by the time you do turn it back up voltage should come back up too.

yay for electrical storage..!

There is no magic in a cap. There is no "technology" involved. We're talking about two charged plates with a gap between them. Nothing has changed since the phenomena was discovered several hundred years ago. You rattle on like you know something, but at every turn you're flat wrong. Get over it. Learn to read, then actually put that knowledge to use by reading something about the subject and actually learning that is correct rather than continuing to spout your misconceptions as fact.

There he is quoting someone else to point out where they are wrong. Might be you...

**this event has a name and a value.. making some caps better than others****this event/threshold has a name and a value.. making some caps better than others**

** these events have a name and a value.. making some caps better than others**

**this event/threshold has a name and a value.. making some caps better than others**

**again, this event has a name and a value.. making some caps better than others**

i am sorry.. i do not know the names of each event, nor do i know what the ideal values are.

I think you are really on to something here. Your expertise on this subject is duly noted.

Id berate you further, but Ive expended all the patience on you I have at the moment.

That magic technology he is referring to are all those events/thresholds he doesn't know the name or value of.

This guy's kinda spooky, isn't he?
