Hmmm.....
This EESU is supposed to be in the realm of a capacitor but why does it rate discharge at 20Ah? Maxwell capacitor as well as others are in the 2800Ah to 3200+ Ah discharge rate ranging from their 100F to 500F 16v products. This sounds more of a battery to me. Maybe they're trying to come up with a new coined fancy name for a battery?
I'm sure they have "something" there but I think it's nothing more than a higher density "Battery".

Anybody see this. Low-cost oil from leftover coffee grounds. "The researchers report that the exhaust actually smells like coffee." Not sure what Starbucks would think? For some reason a think sitting in traffic smelling all that coffee...just can't be good for the brand. Hahaha.

I believe the actual capacitor operates at a higher voltage and the current rating is for the conversion devices.

Yes ! Excellent, i agree.

 

[Jake]

I was wondering about the discharge rating as well. 20A continuous from a 26 Ah device is...not much. 80A burst is not much either. I'm not sure what Mike756 meant by "The current rating is most likely a function of time at current." Of course it is a function of time...and for either "infinite" time or short bursts, this particular device falls far short of the Li-Ion batteries being considered for use in the Volt. The equivalent capacity Li-Ion battery could supply 20 or 30 times the continuous current.

However, I'm not going to write off EEStor just for this reason. I just couldn't help but notice the seemingly low current rating.

I’m temped to jump on his train and be right about this. But…as Tim says, Im still wondering why Lockheed would spend time on this, unless it were valid. Perhaps the military gets the “A” version, and statik will be driving the “C” version?

=D~~~~

We do not need to view the Lockheed Martin deal with EESTOR as proof of anything. LM is a diversified and decentralized company. I suspect a mid-level manager somewhere has some funds in his budget he was willing to take a chance with. No figure is given, so there is no reason to think the deal was scrutinized by the LM board.

This is similar to the well known scam artist who is in the business of promoting licenses to mfgr compressed air driven cars. He has a deal with Tata Motors, part of Tata Industries, a well respected conglomerate out of India. Tata has held a lisence for 8 years now, but still no car.

How many small companies have brought game changing technology to energy storage ? Esp. ones who behave like EEStor does ....

 

[Joshua Bretz]

Many posts above noted the limited current specs (which should be much higher since this is a capacitor). My take on this is that the current specs come from the fusing alone. The electric vehicle EESU described in all their patents operates at a much higher voltage (up to 3500V), presumably to keep the current required for fast charging to a resonable number.

"Do the math - your odds of being struck by lightning are greater than the odds that you’ll be scammed. People see one or two companies out of 12,000 caught doing something wrong and stupidly assume they all are crooked. Then look at the percentage of citizens who cheat on their taxes. The number is staggering, yet these folks also assume the average Joe is honest. Their beliefs are pure dumb."

In the 1980's I was at Ft. Leonard Wood, Mo learning to use US Army comm. equipment that had Li Ion batteries. The batteries had a tendency to overheat. Funny how the USA can get advanced tech going when folks are committed to it. Shortly there-after I went to Ft. Belvoir, Va to train to work on field erected bridges. I was walking out of the barracks area one day and a light rain started.

Having been raised in Southern California I thought weather was a benign thing and wondered why everyone was running so deliberately to get out of a light sprinkle of a warm rain. Then about ten feet to my left a cypress tree crackled, exploded and dropped a limb from a lighting strike. Go figure. I guess getting hit by lightning is a lot more likely if I do dumb things based on my ignorance of what's likely to occur next.

If EESTor's 24V package is not a scam, the peak current constraints come from the DC-DC power conversion device that steps down 3200 volts to 24 volts.

A Volt run on an eestor ultracap would have a different and more robust converter.

[big gumby]

I hope that EEstor is for real. Why don't they just put it in a car or in a static display? They wouldn't have to give away any secrets.

On another subject, how about some more info on the VOLT mules?
Maybe GM could put another video on Utube. Better yet let Lyle drive one!

 

[Jay_Wells]

There is no such thing as a "trademark patent."

 

[Dick_G.]

Volume: 9.44 x 10 to the 5th mm cubed does not equal 106.6 mm cubed.....It equals 944,000 mm cubed.....a cube about 3 7/8"
Did I convert correctly, if I did something seems to be way off.

Ditto That

Electric Cars + Nuclear Power = American Energy Independence!

This solution has been available to us since the 1970s. It's astounding but Pogo said it, "We have met the enemy and he is us."

Maybe EEstor is 'green' Cheese?

#54 Tim Says: "1) I believe that only 50% of the Volt’s current (pun intended) 16 kWh li-Ion battery pack will actually be used in order to keep from damaging the pack.

100% of the EESU capacity can be used without damage therefore it will only NEED to hold 8 kWh for the 40-mile E-REV “sweet spot” range. "
--------------------------------------------------------------------------------------
Not true!

When the engine comes on, you still need significant charge in the battery to get up long uphill grades. This is a basic part of the series hybrid (a.k.a. EREV) design. 4.8kwh may be overkill, but you still probably need something like 3kwh for long uphill climbs.

Also, if you happen to live on the top of a mountain, and you start your way down with a full charge, then you need somewhere for the regenerative braking energy to be stored, maybe another 2kwh for that. So even with a perfect electrical storage device, you'll still need about 13kwh to make the Volt work well in all conditions.

But this may be all mute, since the EESU specs in the article indicate you would need a 160 kwh pack to generate enough power for the Volt's 120kw electric motor. See post #18 for details.

I disagree, for many reasons:

1) Only 45% of oil consumed is gasoline. We import around 66% of our oil. Even if all gas engine cars changed to electric, we would still be importing around 20% of our oil.

2) Most of the fuel sources for electricity in the U.S. are already domestic, so Nuclear isn't mandatory for energy Independence. We could just burn more coal.

3) Plug-in cars are not good for long distance travel. To make long distance travel without oil viable, you'll need to either:
a) EVs with huge batteries and trillions of dollars for a new fast charging infrastructure, or
b) a combination of EREVs and ethanol for longer distance driving.

4) Nuclear power plants are not great at meeting variable or peak demand. They tend to be best at providing a steady amount of electricity. For this reason, nuclear power plants are generally only used to supply base usage (i.e. the minimum amount of electricity used around 3am). Peak power will have to come from somewhere else. Solar is an excellent candidate to cover peak power usage.

Bottom line: There is no magic bullet that will solve our energy problems. We'll need a combination of Nuclear, Solar, Wind, Geo-Thermal, Cellulosic Ethanol, Bio-diesel from Algae, and Energy Conservation to become energy independent.

Sooner or later they have to put their product out there to be seen. If not, we can write them off pretty quickly. Time will tell. They seem not to be in any hurry to open up to the public. Maybe they have good reasons and maybe it is just an excuse to not let us know how unsuccessful they really are. Who knows at this point. Not me for sure.

France has 80% base load?

Nuclear units only can be built in one size?

You can't move the control rods?

I think we should surround the country with aircraft carriers and use their nukes for our energy needs. LOL

Good luck with more coal - apparently we have a different perception of present political realities and physical surreality. We in Roanoke VA just had a 30% rate increase for pollution equipment on coal fired plants. I can breathe better already and the oceans are receding.
