Skeleton Ultra Capacitors | Fully Charged

[@stevenhiller2253]

When I first say the title of the video I expected wild claims about supercaps replacing batteries. Pleasently surprised, the guy was very honest and provided clear explanation about the strength and weakness of his caps. Very well done.

[@ClockworksOfGL]

Steven Hiller - Elon Musk started out thinking super-capacitors were the ultimate energy story solution, but the physics just don’t pencil out. They’re very seductive and definitely have huge advantages over batteries in many applications. But for cars....not so much. People don’t seem to realize how much power modern LiOn cells can pump out. Obviously, super caps will blow away any battery technology, but LiOn cells are good enough to throw a 4000 pound vehicle forward at an amazing rate.

[@stevenhiller2253]

Bryan Noga Yeah, even using caps for Regen seems like you'd need at least 1kwh to absorb braking energy and provide acceleration. A bank of ultracaps to do that wouldn't weight that much but they'd take up a lot of space.

[@fredivory4304]

Bryan Noga I think the whole point was a mixture of both in a car. The caps to accelerate quickly and store the regen power as quickly then let the lithium basically cruise. That way the batteries will provide much more run time since acceleration really eats their power.

[@ClockworksOfGL]

Steven Hiller - It probably depends on the car. I believe Ford hybrids have a 0.6 kWh (?) LiOn battery, but I’m not sure exactly how much capacity is actually used by the vehicle. A super cap would be a good alternative, and also have the advantage of being less sensitive to temperature & storage.

[@fredivory4304]

Bryan Noga A mix is best. Caps for the start and stop spikes and batteries for cruising. The batteries will last much longer if the don't have to pull the car up to speed.

[@Dave-in-France]

In my opinion - this is the best video blog/story you've ever made ! Estonia - beautiful country, educated people, great national philosophies (broadband for everyone). Ultra capacitors (EC's) - HOW BRILLIANT are these ???!!! Sucking in massive amounts of power in seconds and stuffing it out again. Brilliant for taking out peaks and troughs of grid demand but also using them in combination with lithium-Ion batteries in automotive applications, EC taking all that regen energy, delivering it during phases of acceleration - just a brilliant concept. As you may have guessed, I lurved this video - just off to watch it again !!!!!

[@fullychargedshow]

Thanks so much for commenting David and we're really happy to hear you enjoyed it.

[@jur4x]

Nice country. But dirty dirty electric power. Most their power comes from oil shale, which apparently is even worse than coal. not only it outputs outputs over 1000g CO2 per KWh (compared to coal's 800g), but also 46% of fuel turns into highly alcaline ash. www.electricitymap.org/?page=country&solar=false&remote=true&wind=false&countryCode=EE

[@willdarling1]

ent Estonia brilliant !?

[@jur4x]

They kinda are. Especially since they managed to do better then neighbour Latvia. They didn't loose 10% of country's population due to emigration. And it is much easier to do business in Estonia then in Latvia.

And sadly it (energy coming from oil shale) is not improving any time soon, though some renewable energy is being added.

[@Buzzhumma]

The ceo is a wonderfully bright and focus individual and kudos to him . Every thing he discussed about the benifits was what I realised 15 years ago on an electric bike I set up. It had and underpowered Lipo battery so I intergrated some supercapacitors to negate the voltage drop under high acceleration . It would cause the electronic speed control to shut down due to low voltage cut off but the super caps solved the problem so I went the next step with regen braking and so forth. Cheap and amazing efficiency gains . Around 15 -20 % estimated gain and obvious battery longevity gains too . Good luck to this company and good forward thinking . Regards Andy from Australia !

[@allaneves180]

Hello Electron Proton Neutron Mouron Quite the name I must admit LOL's. I was wondering if you could send more detailed information of what you did to modify your e-bike 15 yrs ago. I have an e-bike now (60 Volt, 20 AmpHr battery power system. No regen capability. On 2nd set of batteries now. In need of 3rd set and considering Li-Ion packs. I'm learning though that the charger will likely have to be changed also. Current pack type is 12 volt 20 amphr x 5 packs in series. Sorry right now drawing a blank on type of battery pack. "Gelcell" is all I can think of right now Could you forward specifics of your modifications to set up the Capacitors and also the regen arrangement. Send an email to [e-mail] and we can start communicating on this subject Thank you

[@metamorphicorder]

Yes please provide contact info to be able to get your plans for this set up if you have them. You had lipo 15yrs ago? Factory bike or self built? Brand of bike if it was factory built.

[@Buzzhumma]

metamorphicorder they were just cheap Chinese 10amp 24 volt lion for this bike but the output power requirement from standing start was more than what the battery could give due to voltage sag and the motor controller would shut down due to low voltage cut off . I got around this with the super caps in parallel . The initial power draw would come from the super cap and after depletion the batteries would become the supply but the initial higher power draw has dropped of by 30% or so and allow the low voltage cut out to be ok

[@Buzzhumma]

Somnath Roy haha no but I did learn from his venture about being careful what you get involved with as it might become your whole life . I don’t envy his life at all . Far to much for one man to be responsible for !

[@AleksandarStefanovic]

Combining batteries with capacitors to split different types of loads is a very good idea!

[@arkatub]

I'm pretty sure they already do this, but usually put the capacitor just before the load.

[@ayuminor]

Yea it's one of the most basic concepts of electronics, but to be able to apply it to high power applications is a big deal.

[@LoanwordEggcorn]

It's not needed. If the battery pack is large enough, it can give and take lots of power by itself.

[@aeonturnip2]

Loanword Eggcorn: I think they said that, but with BEVs there is always the issue of weight and size of the pack. These capacitors provide a small and light way of both "absorbing" and providing a large amount of energy quickly - i.e. for regen braking and acceleration. They also avoid the need to pull and push a load of current in/out of the battery which can cause degradation through heating.

The presenter should be given an award or something . As a renewable energy advocate my self , i found this very entertaining and informative as well.

[@maxtorque2277]

Three points of note need to be made whenever talking about batteries vs capacitors: 1) Batteries do not "store" electricity, they convert electricity into (and out of) chemical energy. ie the energy is stored by change in chemical balance within the cell. This is why they are "slow" but "energy dense" Capacitors directly store electric charge, the lack of chemical reaction required therefore makes then fast but fundamentally poor energy density 3) The charge held on a capacitor is inversely proportional to the separation of the charge carrying elements ( C = ( E X A ) / d ), however the maximum voltage a capacitor is capable of withstanding (before charge "leaks" across between those elements) proportional to that separation distance. Why is this important, because Power = Voltage x Current, so high power requires high voltage, which means large separation distances, which means a smaller capacitance value. The current drive for higher system voltages for eMobility applications, which is likely to continue (as both efficiency and cost fall with increasing voltage), tends to start making capacitors bit players in the energy storage game (And if you think "hey, i can just put some capacitors in series, well, sorry, but physics has got a limit there too, as capacitance is the opposite of resistance, so put two capacitors in series and their effective capacitance halves not doubles!) 3) The energy stored in a capacitor is directly proportional to the voltage across that capacitor (U = 0.5 C x V^2). Unlike in a battery, where the chemical reaction is driven by the voltage difference, a capacitor therefore has a voltage across it's terminals that is highly dependant on the charge stored. This means that practical capacitor based energy storage systems require an active voltage converter (DC/DC converter) in order to maintain a reasonably fixed output voltage at all energy levels. That means the power limit of the system is not actually the capacitors themselves, but the power transfer capability of that converter (who's ultimate performance is inversely proportional to the voltage ratio required). Therefore, any meaningful cost comparison with battery storage MUST include the cost of that vital voltage converter, ie you cannot just compare the cost of a capacitor with a battery, and say "capacitors are cheaper". Today, significant capacitor energy storage has been only realised in high cost systems (buses, cranes, motorsports etc) simply because the cost and complexity of the necessary voltage matching infrastructure has made such systems un-competitive with chemical battery storage systems on small, or cost sensitive applications (ie passenger cars). And while chemical battery costs continue to tumble, driven by huge investment in massive volume production, that situation is not going to change any time soon imo..

[@janvrto4822]

Max Torque questions is why do we need capacitors when will coming soon solid state batteries ?

[@LoanwordEggcorn]

More importantly, chemical batteries can provide more than enough power for typical use in an EV without capacitors, particularly for large capacity packs.

[@LoanwordEggcorn]

Yes, the video said they're using it for regenerative braking on buses.

[@SvenOllino]

well said!

[@rfldss89]

In day to day use, this can very useful for regen breaking, since batteries heat up the quicker you charge/discharge them, and heat damages them. So by implementing a capacitor along with Li-Ion batteries, you're charging up the caps, then transfering the power back the wheels when needed, or charging up the batteries at a slower rate. Think of caps as an energy buffer when regen breaking.

Ultra capacitors have only a small stored energy/weight, but huge power/weight. Consider that, energy/power = time. Amount stored / how fast you use it = how long you can use it for. Small/large = tiny. So they are great for short duration high power applications. But used in combination with batteries they are fantastic! Great idea for commuter trains too. I love this channel!

Hello from Estonia.

[@bruceforster3709]

Let me pose this thought to you: High-End Car Audio Systems incorporate Super-Capacitors in them for large power spikes, because if powered by batteries alone, the amplifiers can't handle some of the peak spikes in power. The capacitors provide the extra stored energy to keep this from happening, smoothing out the few of power. This is an understood fact and has been for many years. So, why then, do you think incorporating this into larger scale power generation facilities is a stupid idea and/or a waste of money? One SMALL scale practical application I can see for large capacitors would be for lighting systems. The Goal Zero lite A Life 12 Volt 350 Lumen light could burn continuously for WEEKS on just one supercapcitor, and when the Supercapcitor is exhausted can be recharged in 90 seconds, and then run the light for weeks more. Yes, this technology IS in its infancy, but don't dismiss it out of hand. I'll take this over a Coal or Nuclear Plant, thank you very much.

Kwh without /

[@MrVelociraptor75]

​@@simonecipriano You can use both. The slash represents (and is usually said, when spoken out loud) as "per". Meaning, "every" or "over" (as in "over time", in this case). So something that is rated at 2kW, will consume 2 kW/hours over an hour period, (or 1kW/h every 30mins etc etc) - same usage as kilometers (or miles) per hour kWh is shorthand. For best practices too, you want to use is a capital "M" (for Mega) - to diferentiate from "milli" and if you want to get technical, a capital "W" for Watt, as that's its letter. (plus if you want to get even more technical, use a lowercase "k" (for 1000), as an uppercase "K" is usually to represent a binary "Kilo" (for 1024)

[@marcovoetberg6618]

@@MrVelociraptor75 Hmmm, nope sorry, but you misunderstand. kWh is *not* kW per hour, but unstead is kW * (times) h. If something is rated 2kW it means it consumes 2kW or 2000 J/s. If you do that for an hour you get 2kWh. Another device which is rated 4kW run just half an hour will also have consumed 2kWh (4kW * 0.5h). As you can see you have to multiply the energy consumption in W (= J/s) by the amount of hours run to make the units work.

[@marcovoetberg6618]

In other words: 1 KwH = 1000 W * h = 1000 (J/s) * h = 1000 (J/s) * 3600s = 3.6 MJ

​@@marcovoetberg6618 I'm hoping English isn't your first language and you've just had issues reading what I wrote. Because you're trying to argue against me, by saying THE EXACT THING I SAID! Although a slash "/" is usually used as a divide symbol in math, in physics it's used to represent "every" as I said in my first post. Mathematically, yes, you (often) multiply, when trying to work out how much power something is going to use, or has used. But that's not its meaning. Like I said, it's the same usage as speeds and distances. km/h is kilometers per hour. If you're travelling at 100km/h speed, you'll have moved 100km from your starting point after an hour. Same as light year, the distance light will travel after a year...

Fully Charged rocks. I've watched and been a fan right from the early days and I never fail to learn something from your fascinating, well-produced and thoroughly enjoyable videos. Thank you Rob and FC team.

[@DazeDream]

Love the tidbits of history at the end, great video!

This is a good rational explanation without the repeated hype about the technology!

Look how beautiful that country is. Wow just walking down the street looks amazing!

[@EliteClinicalResearch]

Shane Semler what made you leave America?

[@Suralin0]

I visited Estonia in my early teens; the first street Robert was walking down looked like one I went down back in 1999. The country was still at the tail end of recovering from the Soviet era at that point; I'm glad to see the Estonians are doing well these days.

[@RazsterTW]

Lot of graffiti.

Agreed, I was just about to ask if you had ever visited Europe!

Gorgeous Camera Images. And handles the contrast range so well on those outdoor shots

I love this video: Lots of explanations and more importantly lots of demonstrations. No shiny computer graphics or "artist renditions". So keep it up.

[@uwemuller2944]

Fascinating! Thanks for this very interesting and astonishing information. I visited Tallinn last year and it was nice to see it again. I loved the historical town centre. But I didn't know these incredible facts about Estonia.

[@chadj.w.anderson5473]

Mad props to your camera person who seems to have an amazing ability walk backwards for roughly .5km.

[@jeschinstad]

Did you know that if you turn around and walk in the same direction, you're going forward? :)

[@SxWerks]

Much can be accomplished when you have a leadership focused on advancing the common welfare of the country. Thxs for the primer on super capacitors.

[@EnglishTurbines]

Ben....agreed, unlike Britain's group of EU led rabble we call our "Government"

[@jrusselison]

The internet = knowledge = progress 😃 Notice the new and expensive cars amidst well maintained environment and ancient buildings 😃

[@justsomeguy934]

Sounds like an excellent engineering proposal. The description of using capacitors for immediate storage/discharge is exactly what CPU chips do with an on-board memory cache. A cashe will store, say, a megabyte of memory cache so that the CPU doesn't have to go off-chip and wait on a memory request for information. That cache, while small compared to the total memory capacity of the computer, saves countless delays in getting a request completed. If, as the company states, such a cache of energy in an EV would double the service life of the battery, it's a win-win for everyone.

[@karlp8484]

This is the very first productionised use of graphene I've seen, and I'm so glad it's cheap to produce. Solid state has arrived.

[@johntheux9238]

Two times the specific power and 3 times the specific energy of skeleton ultracapacitors: www.nawatechnologies.com/en/products/

[@malbrownie]

That was a great episode. I like the way that young man described the blend of the two storage systems. We have literally only started this trip to energy storage. Of course, when I say “we” I obviously don’t mean we in Australia. Regretfully, we are still talking about building new coal power stations. My embarrassment is overwhelming.

[@mururoa7024]

Amazing technology. Makes me hopeful for the future.

[@aws47]

It's great to listen to articulate people talking knowledgeably about things they're good at!

[@aws47]

and I enjoyed listening to Taavi too...

[@mizizhere]

This red head was awesome, he gave such good explanations of everything! One criticism which is for you, it would of been nice to actually introduce him, his name, his position. Seems strange to interview someone and not to give the audience the basics of the interviewee. Overall a very good video, thumbs up!

[@thewolfdoctor761]

8 out of 10 Estonians are redheads.

[@8Ugri8]

Thank you for kind words about Estonia

Estonia: "Internet is a basic human right" Uganda Gov't: "People must pay a special Tax to use Social media after paying highly for the internet"

Australia: we're going to build next generation fiber to every household. Actually nvm, lets just make a frankenstein network of 30 yrs old copper, coax etc and call it a day.

Tallinn is a great city to visit and the people are lovely. Been many times winter and summer. Great episode thanks!

Wow another great video guys. Keep it going.

[@DickyChap]

What a wonderful place! Inspiring. Brilliant episode too, thanks Rob and the whole FC team!!

[@johnknight9150]

If you can do this for acceleration in cars, could capacitors help in home circumstances of sudden load, such as in hair dryers and toasters?

[@TS-jm7jm]

not necessarily because the load compared to the mains(in a properly wired house) is not much.

[@dirkworldwide]

Thank you for your wonderful impressions about this little country ... we heard about so small. The future battery technologies coming from there ... unbelievable! Thanks

[@Paxmax]

That discharge with the heavy duty cables was probably in the range of 1-4kA... Even stiff thick cables start to do weird stuff above 1kA.

[@Markle2k]

That looked like the 170v/53F module that they have on their buy me page. That would be quite a bit of power.

[@redshift3]

I guess they discharged it through a resistor. I would expect a much more dramatic (dangerous) cable movement with a short circuit

I remember watching this show two years ago. Amazing information

You always seem to find the best people to interview! And the best hosts aswell of course.

not just great talk about tech, but great talk about Estonia as well by this guy..

very informative and inspirational for the future ..more videos like these please..

Wow, Estonia really does sound like a nice place to live. Thanks for the insight!

[@zapfanzapfan]

Cool, didn't know Skeleton was made in Estonia.

[@shbhu270]

Can't believe they exactly working on the concept that I was thinking about last two years. "Storing the breaking energy to the capacitor alongside hybrid battery and using the power from capacitor to launch the car".

Oh the production quality. Brilliant video and beautifully shot.

Red hair is a Neanderthal genetic trait. Must have been a smart type of human.

[@OmniSzron]

This is all fantastic. I'm also thoroughly impressed with how many ladies work in that lab. Estonia really turned their fates around after being a soviet satellite state for all these years. Their development model seems somewhat enlightened compared to what we currently have in Europe.
