Originally by: Tigobitty
To my knowledge a capacitor is capable of much faster recharge and discharge of high energy, whereas a battery is more for longer term storage of said energy. Even in just a frigate, the dynamic energy levels produced by module requirements are astounding, a Battery would have troubles coupling the reactor output to the load without running into thermal issues, or just flat out kersploding.
Confirms that what powers our ships are fusion, think I read that somewhere.. From now on I'm gonna assume that The Capacitor is just a huge bunch of capacitors available for discharge. But then that doesn't sit right with the nonlinear recharge rates..
CCP, answer question plx.
I imagine the power source varies from race to race and ship to ship, though the obvious answer is actually an antimatter reactor, since that's got a higher energy produced/unit of fuel than fusion. The capacitor is the common point for all ships, since any given ship needs a way to store generated power for non-continuous uses, and forcing a battery into rapid charge/discharge would screw it up fast.

Originally by: Feawin From my understanding, the difference between capacitors and batteries is that while a battery allows for a constant voltage during its discharge, the capacitor's voltage during (its rather short) discharge decrease exponentially. So shouldn't the capacitor used on all ships in eve tehnically go under the definition of a battery?
Or am I talking gibberish?
The battery as a power source? or power store? the capacitor is a power store, they are entirely different things. The capacitor can provide more energy faster than a battery. You can if you so wish chose to belive the power source for your ships capacitor is lots of batteries if you want, but its far more likely it is energy from your ships engines that charges the capacitor, as unlike batteries it wont run out (seemingly none of the four different racial propulsion systems need fuel)

Originally by: Thremill i guess it would be safe to assume, that the ships run on fusion reactors, since fusion ammunition is readily available. But then again you know what they say about 'assume'
Well we have fusion bombs at the moment, doesn't mean we have fusion reactors, way way easier to make a fusion weapon than a safe reliable controllable power source or we would hav ethem already. I guess fusion amunition is essentially a tiny fusion warhead so are no more advcanced (except in minaturisation) than the hydrogen bomb.

Originally by: Gunnanmon Simple, they couldn't think of a good way to implement a power source, so they chose a capacitor. Quite what charges the capacitor up escapes me.

Originally by: Sig Sour Edited by: Sig Sour on 14/09/2010 20:33:43 So why are the modules that expand your capacitor called "Capacitor Battery" and not "Capacitor Expander"?
Also you guys should buff the ****ing **** out of those mods so people use them.
The max load on a capacitor cannot be expanded without replacing it, batteries can be added to increase the overall circuit's max load. This or,
Because Fred has been expanded to the max by it's builders , and thus cannot be charged further by Barney. Said Barney however enjoys the longer charges and discharges of Fred, caused by Wilma, and thus created miniature Freds, allowing for a bigger charge, allowing for longer discharges.

Capacitors are often used in conjunction with a power source.
You store charge on them, so you can get extra power when you need it. Presumably the ships of eve have a power source, which has the sole purpose of running the life support, propulsion, etc, then as available, it diverts energy to charging the capacitors, which have non-linear charging, essentially the more charge on it, the slower it is to charge. Then as extra power is needed, say to run a module, the capacitor has the power (current and voltage) to run it.
One major advantage of capacitors to batteries is mass and on a planet weight, at least in the lead-acid sense, although for equivalent power capacity, even rechargeable batteries have more mass per charge than capacitors. This weight a. Many model airplanes now use capacitors instead of batteries, as do some un-manned gliders.

Originally by: CCP Greyscale Obviously this is The FutureÖ so all tech is subject to arbitrary awesomeness, but from a usability/intuitiveness perspective, I think most people would associate "battery" with long-term storage and "capacitor" with short-term storage. With the way the EVE module system pumps charge in and out very rapidly, it makes more sense to more people to call the storage device a capacitor than a battery.

Or you could point out a cap is in fact a battery, and seeing as this is the future, we can say we have better caps than now (as it would take a HUGE cap to hold a simple AA batteries charge) and... cap makes perfect sense... in fact a battery for how the cap works (while unstable) would be wrongà and the fact it is always recharging only makes it more like a cap, and less like a battery.
You could not fire any energy weapon without a cap.

Edited by: daddys helper on 15/09/2010 03:35:17 also in RL we use caps not only as short term storage but as power conditioners (short term is misleading, a capactor can hold a charge for years or till its discharged)
most electronics that plug into the wall actually run on DC (direct current) power and not the AC (alternating current) that comes out of the wall, so we run the AC (a wave that goes from a positive voltage to a negative voltage and then back again) through a bridge rectifier that converts the AC sine wave into a fairly flat constant (or DC) voltage. The caps come in after that to buffer out the ripples left in the DC to give a nice flat stable voltage. So in effect the cap uses its fast charge and discharge properties to absorb the left over ripples in the power.
caps are so much more then batteries with caps you can turn 110 volts into 10,000 volts or more(voltage doubling) and a charged cap from a radar set will effectively wake a room of sleeping engineering students when discharged with an insulated probe

Originally by: Feawin Edited by: Feawin on 14/09/2010 21:45:09 So, the Capacitor is actually a collection of capacitors, which makes it possible to discharge it partially and add more "capacity" in the form of "capacitor batteries" :)
I'm glad we worked that out. I've been pondering this question for several days now.. Now I can finally sleep. Yes, seriously.
EDIT: No dammit, then why does it recharge nonlinearly?
Capacitors don't charge linearly, the charge faster at low charge and decrease in a nonlinear way as the capacitor gets full.

Err ... A battery is not a capacitor. A battery relies on an electrochemical reaction to produce electrons. A capacitor simply collects electrons and is incapable of producing them.
Fun fact: you could power Las Vegas for a little over 51 minutes on a summer day for the same energy cost as it takes to run a 100mn mwd for ten seconds.

Not entirely true, a few years ago a Japanese firm (I think it was Japanese anyway) developed a slow charge releasing capacitor aimed for use in an electric car, was only in the research stages but they had managed it. Problem was it was difficult and expensive to produce for car-sized version.
Unfortunately as it was a few years ago I have no idea where I read the article. But some googlenerd will probably find it.

One should understand the differences between a capacitor and battery before one openly discusses them.
A quick trip to wikipedia should alleviate any confusion. When you say "fanboi" try to picture a fat man doing burlesque with 2 big ass fans that say CCP on one and HTFU on the other. Because that dude is me. |

But then, as far as i can see the game doesn't use the natural logarithm for the recharge of the capacitor. As capacitors recharge fastest at 0% in reality and not at 30%. Explain your science please Yes i know, it's a fictional universe. But come one!

"In reality" you'd have various parasitic inductances, capacitances and resistances, conceivably overload prevention devices, and battery or power source output characteristics that could well result in a different shape of curve for the capacitor recharge.
But it's also because of Science.

Possibly a highly focussed stream of charged particles to cause dieletric breakdown in the capacitor?

So Feawin might as well be correct. What is the recharge rate based on? And what do you actually display with the percentage of the capacitor? Voltage would change based on the natural logarithm. Energy would change linear.

Ya know.. charging a capacitor with a constant current will cause it to be filled linearly with electrons?
