Feawin Gallente Northstar Cabal	Posted - 2010.09.14 15:27:00 - [1] 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?
Lady Ayeipsia	Posted - 2010.09.14 15:30:00 - [2] Ah, but doesn't a rechargeable battery (as these would have to be) have a 1/2 life were after a period of time, the max charge held decreases? A capcitor does not face this issue I believe. That said, whatever the terminology, it doesn't matter. It's a measure of the availble energy your ship has. You could call it Fred and it would still function the same way.
Tigobitty Caldari Australian Mining and industry Corp Intergalactic Exports Group	Posted - 2010.09.14 15:51:00 - [3] Ok, thats it... from now on my ship's power core will be referred to as Fred. Yes.. yes.. I think I like that. -------------------- "A good skirmish is one you can live to fly away from... a Great skirmish is on where you can still use your ship afterwards.."
Gunnanmon Gallente The Scope	Posted - 2010.09.14 15:53:00 - [4] 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. Signature locked for discussing moderation. Navigator

Mr SmartGuy	Posted - 2010.09.14 15:56:00 - [6] It's embarrasing enough that you are using Internet spaceships to amuse yourself. Don't make them Internet spaceship toys that runs on batteries.

Quite what charges the capacitor up escapes me. Uhh, your ship's power reactors? The reactors on your ship power life support, thrusters/subwarp engines, keeping the warp drive online (in a ready state), basic systems, essentially anything that absolutely positively has to be running at all times, anything extra gets funneled to the capacitor for your "non-essentials".
Axemaster	Posted - 2010.09.14 16:04:00 - [10] Capacitors are used because they can output a very large amount of energy very quickly. They are charged up by batteries or the ship's reactor. Learn basic science people!

Tigobitty Caldari Australian Mining and industry Corp Intergalactic Exports Group	Posted - 2010.09.14 16:07:00 - [11] 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. To use a water analogy, I see a capacitor as more of a single giant resevoir with a very large in and out pipe vs. a hundreds of smaller cells networked through small tubes. As far as what charges it, our ships are equipped with some sort of reactor that runs on... something... installed in the ship by .. someone... at ... some point.. and are apparently very efficient. -------------------- "A good skirmish is one you can live to fly away from... a Great skirmish is on where you can still use your ship afterwards.."
Thremill	Posted - 2010.09.14 16:23:00 - [12] 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'
Windows ME State War Academy	Posted - 2010.09.14 16:30:00 - [13] I'm sure they just picked capacitor because they want to have a more scientific sounding word than batteries, and one that common people can understand. To all physics*** here: there is no physics in eve. - Windows ME, defragging your harddisk since two thousand.

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.
Daedalus II	Posted - 2010.09.14 16:52:00 - [16] As others have stated, the reason they use a capacitor is because they are way better than a battery when it comes to discharging and recharging power. Just look at the crazy amount of power a carrier can use up in a matter of seconds with all modules running, no battery could handle that. As for what recharges the capacitor: T2 components Look under each race and you'll see they all have their own reactor technology (just like they have their own sensor and propulsion technology). Amarr use antimatter reactors. Caldari use graviton reactors. Gallente use fusion reactors. Minmatar use nuclear reactors.

John Comer	Posted - 2010.09.14 18:34:00 - [19] its barney that charges up fred, wilma is discharging him
King Dave The Collective	Posted - 2010.09.14 18:43:00 - [20] Some minmatar ships still use 20th century solar panels. --------- "Evil Edna > just get director roles, put child **** in the corp bio and then petition ccp"

The Crushah Gallente The Python Cartel. The Jerk Cartel	Posted - 2010.09.14 18:48:00 - [21] Come on guys! Its all done with capacitors these days!
Kendon Riddick	Posted - 2010.09.14 18:56:00 - [22] my sweet '86 vauxhall Nova with twin 15" subs that i like to play Rap out of full blast, i havnt upgraded any of the car parts and my lights dim when the bass notes come in, do i need a big capacitor?

CCP Greyscale	Posted - 2010.09.14 20:17:00 - [23] 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.

Sig Sour	Posted - 2010.09.14 20:31:00 - [24] 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.
Rewind12 Heaven's Army Fidelas Constans	Posted - 2010.09.14 20:41:00 - [25] Edited by: Rewind12 on 14/09/2010 20:41:30 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.
andeira	Posted - 2010.09.14 21:19:00 - [26] well there are things called capacitor battery's in eve you can fit on your ship. But since almost everyone agrees they suck and are almost never used why would we want to use them on our ships? So we decided to drop the battery part and keep the capacitor part. Would that explanation do it for you? ----------------------------------------- Tengu's: is there anything they can't do?
Berikath	Posted - 2010.09.14 21:37:00 - [27] Originally by: Tigobitty As far as what charges it, our ships are equipped with some sort of reactor that runs on... something... installed in the ship by .. someone... at ... some point.. and are apparently very efficient. The reactor is actually a pocket-sized universe the ship draws power from. It's filled with nothing but hamsters running on wheels to generate all that power. My universe is named Fred. (At least, this is my working assumption.) *** Wish list for PI: One-click input routing Copy product, inputs & outputs in factories *Launchpad upgrades: twice the space, twice the cost, half the hassle!
Feawin Gallente Northstar Cabal	Posted - 2010.09.14 21:43:00 - [28] 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?
Ghoest	Posted - 2010.09.14 21:50:00 - [29] Its because capacitors can charge and discharge much faster than batteries. additionally as noted above batteries wear out. Capaciters are better suited to being used a buffer between generation and load than batteries, which is basically whats supposed to be happening with EVE ships. Wherever you went - Here you are.
Berikath	Posted - 2010.09.14 21:52:00 - [30] 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. Capacitor batteries have some things going for them. They give a static increase to capacitor instead of a %, so under certain circumstances they can give far more benefit than a cap recharger (much like shield batteries can be used to make a completely passive shield tank). Problem is, they're only really useful for cap-stable setups. AFAIK, PVP generally uses injectors since you won't be fighting long, and PVE... well, in PVE you're probably flying Caldari so need the mid slots for your shield tank. Also, you need to be fighting for quite a while before batteries are more useful than injectors. * Wish list for PI: One-click input routing Copy product, inputs & outputs in factories *Launchpad upgrades: twice the space, twice the cost, half the hassle!
