Irrelevant. You're still limited by supply rates and feed wire heating.
LOL. No, you most certainly are not. Supply for the vehicle is from local storage, charged slowly over time, ready for fast discharge when needed
LOL yourself. You were crediting ultracapacitors with fast charging. Now your "counter" is saying that no, you're talking about slow charging. Well, make up your damned mind.
As for feed wire heating, that's absurd. At these lengths, and these voltages, it's simply not a problem.
At the *thousands of amps* needed to surpass the charge rate capacity of li-ions, yes, you bloody well are talking about wire heating problems.
I know that with multiple high energy motors, motor peak current demands can be very high, particularly in the case of high power motors that batteries aren't good for, and that semiconductors can be arranged for very high parallelism.
Oh, please, get real. The supercar-performance Tesla Roadster uses a 215kW motor peak, max 100kW sustained. To drain the whole pack with the pedal to the floor constantly (which, as noted, the car doesn't support) would take over 15 minutes. The fastest you can actually drain it without overheating the car is about 45 minutes. And this is for a car that does 0-100 in 3,7 seconds.
Learn to admit when you make a mistake and move on. The concept that there's sort of car performance limitation from not being able to instantly discharge the whole pack is utterly absurd.
Oh heck no, not even close.
Then follow the instructions in the very next sentence that you ignored. But given that few car parts last longer than 10 years, and most ultracapacitors don't last that long, I think that's an unreasonable demand.
Montana's not a great environment for batteries at times. I'd have to rig a cover for it all, probably lose 6 inches of depth in the bed. Hmmm. :)
Montana? You did see that one of the supercap info sheets linked showed that they're only rated down to -25C, right? Why would you choose that over good li-ions which go down to -40C (some varieties go even lower)? Are you fond of getting stuck out in the cold?
It's only when they are unused for long periods of times that they don't.
In fantasyland, perhaps. Check the specsheets for actual real-world ultracaps, like the ones I linked. They explicitly state that capacity declines from having energy stored in them. So unless your plan is to fully discharge your car after every use, yeah, good luck with that.
The idea that their lifespan in use is ten years is a complete myth.
Yeah, what do those stupid nuthead supercap manufacturers know about their own products? fyngyrz, you tell them what's what!
Yes, yes, of course you can break them if you misuse them
You can break them by precisely the same method you said that you can't, as per the spec sheets of the manufacturers.
UC won't overcharge if a continuous supply is applied to them that is under their rated voltage.
The spec sheets explicitly contradict that.
Show me one in continuous, low cycle rate use that needs to be.
The spec sheets all explicitly describe the exact same internal resistance rise with time. There's tons and tons of peer-reviewed research on it. But no, no, we have fyngyrz here to correct all those stupid boffins!
According to all manufacturer information out there, the primary loss mechanism is not cycling but energy storage. You can cycle them tons without problem, but each second you leave them charged raises their internal resistance. The higher you charge them and the further the ambient temperature is from the optimal, the faster they die.
Look on EBay. Search for them. Look at all the used ones pulled from equipment. Why do you think that is?
For the exact same reason I can do that for batteries?
All of mine are; my initial curiosity resulted in a buying spree, and that eventually turned into the DC supply for my radio station, which requires about a kilowatt and a half when fully dialed up. I get a solid hour of runtime there, more without the linear running. Not a battery in sight. That's been working flawlessly since it was put into service just before 2000.
Whoopee. Because I'm sure you're storing full power in them continuously when you're not using your station, right, and they're operating and being stored at outdoor temperatures? Surely that's the case, because otherwise you'd be making a stupid analogy, and I know you wouldn't do that!
Well, you can say anything you want, but I don't think you've demonstrated any of this
Yeah, damn the manufacturer spec sheets!
Yes, that's exactly what I was talking about. Are you actually ignorant of the rate of technological disruptions we've seen pop up in tech after tech?
And your reason for presuming that they'll apply to supercaps but not to batteries, when the trend is precisely the opposite, is...?
