Eaton’s new supercapacitor offers increased voltage

Power management company Eaton has released a next-generation XLR-51 supercapacitor module, extending the MLR module line to 51.3 V and 188 F. Designed for rugged applications, each module includes integrated cell voltage management circuity, over-voltage alarm, and a temperature output. The XLR supercapacitor modules are comprised of 18 individual XL60 supercapacitor cells.

The 48 V and 51 V modules of the XLR line received UN-ECE Reg. 10 & Reg. 100 certifications, which determine provisions for wheeled vehicle electromagnetic compatibility and environmental requirements for integration into electric power trains.

Nick Stone, Eaton’s Product Manager for supercapacitor modules, said, “Eaton’s new XLR-51 supercapacitor module is designed for environments that demand rugged construction while also being able to meet the high-power, high-energy needs.”

    It is designed for people dumb as a box of rocks. Who wants something that has 30x costs, weight, space of a lithium version?
    Maxwell was going bankrupt as no one in their right mind would buy them, sold to Tesla for the dry battery process.

    • Taco Bender

      Supercaps have different roles than lithium batteries. They aren’t ‘versions’ of the same thing, caps are for extremely fast charge/discharge which they are considerably better at than any chemical battery.

      I read somewhere recently that adding a supercap as a buffer in an EV would allow more energy recovery during regenerative braking which could then be used to drive the motors without using the battery (momentarily at least). The net increase in range worked out to ~30%.

      So yeah, YOU must be dumb as rocks to think that supercaps are somehow a bad thing.

      • freedomev

        You only show your ignorance dude, reread my post and think about it some more until it sinks in why you are the dumb as a box of rocks one.
        If you can think that well as you blew it the first time.
        You read somewhere vs someone dealing with them for 40 yrs.

        • Living in the Mountains

          Super Caps haven’t been out for 40 years…..

          • freedomev

            Sure they have.
            Sorry you’ve been living under a rock but Maxwell has been around since I was young and that was 40 yrs ago plus. And others before Maxwell. Always touting but rarely selling as people see the numbers and gasp and then think, I’m not that stupid, no thanks.

          • raydiak

            Nobody cares how old you are. Can we stick to the facts? If your position has merit, it will stand on its own without your attempts to scare people away from reasonable analysis with an unwarranted rude and belittling attitude. You should know better by your age. It’s a kindness that anybody engages your vitriol at all, much less with any sort of respect.

            The assertion is that a supercap is much more efficient than a battery at buffering the occasional bursts of power provided by regenerative braking, which makes the otherwise lost power beyond the battery’s charging limitations available even after the brakes are disengaged. This allows the battery to continue to receive the rest of that charge even after the brakes are released, to better cater to the inherent physical limitations of battery chemistry and geometry. Additionally, how about the idea that supercap technology is much younger than chemical batteries and may some day exceed their capabilities, but only if the technology is pursued by those with the courage to fail just for the chance to succeed? We couldn’t know right now whether that is that case or not. Even if it eventually went nowhere, isn’t it worth exploring to see how deep the supercap rabbit hole goes, and what we can learn along the way, just like many of your favorite technologies which have or will become outmoded?

            You got into this position by trying to defend the original fallacious assumption that people meant to replace batteries with these supercaps, a defense comprised nearly exclusively of emotional attitude and irrelevant subjective estimate of relative intelligence. Probably because you realized your error, felt embarrassed and vulnerable as is natural, but responded to that with an attempted show of strength like an animal. As an assumedly civilized human, you are held to a higher standard. That’s why you’re not getting the respect you expect.

            What say you to the actual assertions at hand? More slander and hatred, perhaps even degenerate to personal attacks? That’s not getting you the respect you want, though. Try to prove that your experience exceeds us all with a coherent rebuttal? But you’ve kinda painted yourself into a logically undefendable corner at this point. The best you could do is try to pick at my wording or try to twist it into a statement I didn’t make. Maybe bow out with whatever shreds of dignity you retain, even just the dignity of silence? But your ego can’t allow for that kind of weakness, even if it may be the move that loses you the least respect, can it? Maybe just tl;dr this whole load of crap (or at least pretend you did)?

            Your move. Show us all how we’re “dumb as rocks.”

            Again what does 30x the weight, space, cost than lithium to do the same job better don’t you
            understand.
            Why are you so easily fooled by marketing propaganda when someone puts the facts in front of you, you defend the lie?
            Do you have a clue about the limitations of space charge? What are they?
            How about the expensive special electronics to make them work? What re they and why are they needed?
            And that shows you are dumb as a box of rocks, easily fooled and can’t admit facts when put in front of you.

          • Munix

            The Swinbourne University BEST polymer graphene supercaps are light weight and under 30 cent’s a wh 10 times energy density of Maxwell tenth the cost.

          • freedomev

            LOL!!! Keep believing if you want dude. SCs can blow up rather spectacularly far easier, more often than EV lithium.

          • Munix

            No super capacitors being made from graphene, dissipate heat well, there’s been no issues with any reaction leading to any exothermic reaction at all.

          • freedomev

            Wrong. The insulation degrades over time and becomes resistive. When that drops low enough, shorts, superheating happens exploding them. BT, repaired that mess. Unlike you I have actual experience with them . I know the numbers because I costed out Maxwell ones from their data, was not pretty.
            The insulation is so bad they are mostly limited to 2.2- 2.5vdc cells and why it’s life isn’t that long. And need power electronics to keep them in spec. And expensive power electronics to work from full voltage to 0 volts to get it’s full capacity.
            If you want to pay, weigh, space 30x as much, be my guest. Others are not that stupid after looking at the data, specs, cost.

          • Munix

            Who’s insulation? So magic, it works at 4.2 volts but not at 4.2 volts. Wow

          • freedomev

            Again showing your ignorance.

          • Munix

            No moron uses Maxwell, First Graphene supercaps are 55 wh/litre and 15kw/litre at under $0.30 wh.
            That’s 10 times cheaper for 10 times the density of Maxwell.
            They self charge from vibration.

          • freedomev

            You lie. Show the $.30/wthr?
            Assuming it is 10x Maxwell which it physically can’t be , that is still 3x li-ion.

          • Munix

            With li-ion you have thermal issues, you have to model them using the spmet, single particle model including electrodes and thermodynamics. Limited thermal range and efficiency varies over the SoC.
            Maxwell only achieve 5.8wh/litre and they’re heavy, fixed cylinder format only.

          • Munix

            Some of us are not that stupid, under continuous testing, real experience reveals otherwise, it’s cooling of the power electronics that’s the issue, having to use a Graphene enhanced heat transfer nano fluid, 40% better than straight water.

          • freedomev

            What are you talking about? Never mind you are too biased to reason with.

          • Munix

            Solvay provide the insulation polymers, these work very well.

          • freedomev

            Yet fairly short life, high weight, cost , space still. You can have my share.

          • Munix

            If being charged from ultra lean MiLD low temperature combustion IC engine operating at high efficiency, same regimes used in Formula One, achieving over 50% thermal efficiency. Motorcycle where mass equals greater death rate due to handling dynamics, entering corner with rear wheel in the air and front suspension bottomed out is not safest way around corner nor fastest. EV motorcycles never address this issue, fat floppy fork tubes, worse they’re telescopic. Big battery pack just blocks air flow destroying any clever aerodynamics potential.

          • Munix

            Please explain the reaction process for this to occur.
            The thermodynamics and rate coefficients

          • freedomev

            I did dude. I’m done as I have to go build an EV.

          • Munix

            You do realise supercaps are always rated per volume, not mass. These are developed in Australia, printed on a flexible polymer using graphene inks. Two years testing.

            They’re very light weight, 100,000s cycles. flexible polymer allows non conformal packaging, 100 layers typical. High power density 50kw module.

          • Munix

            You sound like an amateur, your EV only going to catch fire. Any idea how much heat your needing to remove? Degradation modeling?
            Aerodynamics modeling?

          • raydiak

            Wikipedia says “Supercapacitors are used in applications requiring many rapid charge/discharge cycles, rather than long term compact energy storage — in automobiles, buses, trains, cranes and elevators, where they are used for regenerative braking, short-term energy storage, or burst-mode power delivery.”

            Do you dispute the validity of that practice across the entire industry?

          • freedomev

            I dispute they can do it cost, weight, space effectively. We actually built a drag race car with them and it did terribly, barely getting through the 1/4 mile .
            What about 30x the weight, space, cost don’t you understand?
            What don’t you understand that most any hybrid battery would easily beat SCs at 3% of the cost.
            And the pitiful numbers deployed prove me right and you, others believing propaganda by Maxwell, now gone, other SC makers..
            You should be embarrassed being so easily fooled

          • freedomev

            Why didn’t you answer my questions? Scared or can’t?
            There is almost no industry in SCs dude.
            It’s why Maxwell went under. If they were so good, why did Maxwell die?

          • Francisco Shi

            When you need to charge and discharge a few times per minute (like for power factor correction or load balancing on power systems) a battery would not last very long. In this case the capacitor is a better choice and weigh and size are irrelevant for this application.
            Capacitors do not use chemical reactions to store the energy so they do not loose capacity when cycled.

          • freedomev

            Yet hybrid EV batteries have been doing just that for 25 yrs now at far less cost,
            weight, space. No?
            You are giving SC abilities they don’t have. They are not long lived as rather fragile, tend to explode, have flammable liquids, etc, you are either ignorant of or ignore.

          • Francisco Shi

            Hybrid batteries only last about 8000 cycles. Capacitors last millions of cycles. I do know about this. I design electronics that use capacitors instead o batteries for this very reason. Super capacitors are not suitable for cars. They are suitable for uses where weight and size is not important and cycle life is. Power stations do not use batteries for power factor correction. They would only last a few weeks if used for that purpose. They use capacitors instead. Super capacitors are the same thing. They are built differently. That is why they have more capacitance than standard capacitors.
            In the long term a battery would be far more expensive because it wouldn’t last very long under those conditions.
            For cars super capacitors are not viable and are very far off before they could come near what batteries can currently do.

          • freedomev

            Hybrid taxis see 8k cycles in 6 months, buses in 3 months dude. They have near unlimited cycles between 20 and 85% charge as their duty cycle clearly shows, No?
            I’ve been in electronics for 50 yrs , heavy power conversions for 40 yrs and NO ONE is using SCs more than once, if at all.
            Power correction is 120x a second and they still don’t use SCs but normal caps. Please show those that do use SCs.
            If so great, where are they all? A few Chinese test buses and other 1 off projects is about it.
            Why did Maxwell die?
            Why won’t all of you answer my basic questions instead of spewing SC maker’s propaganda?

          • Francisco Shi

            Because super capacitors are more expensive than normal capacitors and for that application the extra weight and space used by a standard capacitor is not a problem.
            Hybrid vehicles do not discharge the battery completely every time they start and stop. So they do not do 8000 cycles in 6 months.
            Just because Maxwell went broke doesn’t mean that SC are not useful. They are used in lots of electronics instead of batteries. Mostly for memory retention. They last for the life of the product. Just as any of the other capacitors.
            SC work the same way as standard capacitors. They just use a material that has much more surface area then standard electrodes. More area more capacitance. There is nothing special.
            Also as far as I know SC do jot catch fire. Also consider that the more energy density you have the more energy you have to dissipate in case of failure. No matter how you store it. The main reason Li batteries catch fire is the electrolyte is flammable. And NiMH batteries also catch fire if you do the wrong thing.

          • freedomev

            Just digging yourself deeper dude.
            That batteries don’t have to run 100%-0 volts is a plus dude, not a fault.
            And why do you ignore that 3x the capacity of SCs in a lithium battery weighs, space, cost 10% of a SC in the same job running between 20-85%?
            Memory doesn’t need any power so a normal cap can store the needed amount, SC not needed. Interesting you picked a load of less than 1ma to hang your hat on. Something Metal/air cells have been doing 6 decades now and they don’t need to be recharged all the time.
            Talk about cherry picking.
            Again the insulating liquid in a SC is flammable. Why don’t you know that?
            Fact is you know near nothing about SCs in power service, especially the economics.

          • Francisco Shi

            Here is a perfect example of where SC are a better choice than battery. Fuel injected motocross bikes use a super capacitor instead of a battery. If the battery was cheaper they would be using them instead of SC.
            The requirement is as follows:
            Must be able to run fuel pump to pressurised fuel system for a minimum of 10seconds and a maximum of about 30 seconds.
            The pump uses 6A at 12v. When the bike is kicked the pump needs to run for long enough that the engine starts. Once the engine starts the engine generates the power.
            So we need to store 36 watt secconds. That is 0.01kwh. Or about 1mAh. From those numbers you would need a C rating of about 6000.
            A 1mAh battery would not work. So let’s use a 3Ah 1860 cell. So put 4 of those and you have the problem fixed. Except that if you leave it without keeping it charged in the shed during 6 months of winter at -10C by the time summer comes you have a totally dead battery. So you have to go and buy a new one. The SC will not have a problem being left with no charge for 6months at -10C. When summer comes a few kicks and the bike with a SC starts the one with a battery is dead and it will not start.
            So why do Japaneese manufacturers keep using SC on motocross bikes when a battery is superior? Motocross bikes are all about weight. So why keep using SC instead of a lighter cheaper battery? Are you saying the bike manufacturers are wasting their money and providing a more expensive lower performance product? Why not use batteries like the other bikes they make. It would certainly be cheaper to use something they already use on other models. And by the way they don’t seem to have a BMS on the SC in the bikes. Clearly for this application the SC is a better choice. They have been using SC since about 2012 and they still do. In 2012 SC would have been far more expensive than now. So why no battery?
            I have some friends that have electric start enduro bikes where they have replaced the battery that keeps dying with SC. You just need 3 seconds at 40A and the bike starts. After that a SC recharges in a few seconds and is good to go again. A dead battery does not recharge a flat battery takes 20min before it is charged and if you keep trying to start the bike and you let the battery run flat like every one does when they get stuck you are up for a new very expensive battery and you have to kick start it for the rest of the day. If it doesn’t have a kick starter like many of the new ones do then you have to push start it every time for the rest of the day until you get back home and replace the battery.
            I suppose you have not seen this case have you?
            This is just but one case where a SC is a better choice than a battery. There are many more if you look. Clearly you have not been exposed to enough situations where a SC is a better choice.
            The fact that SC are still being made means there is a market and a need. You just are just too narrow minded to see that there are situations that you are unaware of where SC work better than a battery.

          • freedomev

            Your numbers are very bad. A single 3ah x 4v cell puts out 12watts at 1 c. So 3 will put out the needed 36 wts at 3c, not 6000C silly rabbit.
            You’ll need 5 SC cells and a lot of electronics to keep them alive and able to work with declining to 0 volts power and won’t have 5% of the capacity ..
            Not only that but li-ion will put it out much longer in case it doesn’t crank right up. Fact is with a SC you are going to be push starting it a lot.
            How do the run the FI pump once the SC is used up in 6 seconds?
            As for why, who knows as fads happen. That it is a better choice or hype just look at cost, capacity.
            My 20c cells recharge completely in 3 minutes but for the same energy of a SC that is minute, 5 seconds.

          • Francisco Shi

            It seems a very long lasting fad I they have been doing it for the last 7 years and do not have any sign of changing. The Japanese will not spend 1 more cent if they don’t have to so I guess they keep doing it because it is the right choice and it works. Did I also forget to mention that the batteries go in the air box near the engine which is the only place you can put the battery where it gets well over 45°C on a regular basis especially when you boil the bike which happens often on enduro races.
            The bike I have has a round cylinder about 50mm diameter and about 75mm ling. It certainly is not a battery because you can discharge it to 0 volts. Has two thick wires going in and when you charge in the bike it goes to 14 volts and it holds charge. It always has zero volts after a week of sitting in the garage and it starts after 3 or 4 kicks. After it starts once it fires up every time on the first kick. There do not seem to be any electronics in the cylinder and in 7 tears I have never had to replace it.

          • freedomev

            They do it because they did it and doesn’t have to make sense. For instance Toyotas, Hondas refusal to make BEVs only means they are stupid.

          • Francisco Shi

            They did it because it works well. My brother has had to change his battery more than 3 times in two years. He doesn’t ride the bike much. When he comes to try to start the bike the battery has gone below the safe limit and the battery is dead and needs a new battery. The bike with the SC has never had that problem and it works fine after 9 years. Even after sitting in the garage for 2 years without being starters when I went overseas. Certainly much cheaper and more reliable. I do not see how putting a battery in the bike that uses the SC is going to be cheaper or more reliable. In fact it would give it a bad reputation for unreliability which is probably why they keep using SC on those.

          • freedomev

            If the battery had a tiny amount of the SC protection electronics and pick a decent battery, he wouldn’t have that problem.
            Hint, don’t use MC batteries as they suck big time. Use E bike batteries for it. Even better get rid of the loud smelly polluting POS and get an E motocross that is the big thing now.
            BTW it is easy, fairly cheap to convert yours or one with a dead motor.
            And you can use it near anywhere legal, even early Sunday morning without bothering sleeping people, unlike your bike.

          • Francisco Shi

            Unfortunately the E bikes do not have the range for trail rides. They are good for a 30min motocross race where you go back to the car and change batteries but not for a 6hr 150km ride far away from anything and they are still too heavy. The target weight for an enduro bike is under 110kg. E bikes are 130kg and 2 strokes which is what most people use in racing are about 98kg. Unfortunately before you can get an E bike to be viable you would need over 1kwh/kg for the battery pack.

          • Francisco Shi

            The last battery was one of those Li replacement batteries for MC. Really light and about 3 times the price of the original battery. It has some electronics inside I guess for balancing the cells. And it still died the same way. Left the bike without starting it for 3 months and when he came to start it the very expensive battery was used only once when new and was dead and had to be replaced again. He sold the bike because he wasn’t riding it enough. If we had replaced the battery with SC the first time it would have cost us less money and it would still be running. The SC from the factory doesn’t have any extra electronics visible so it can’t be that much if it can be hidden inside the can. If we wanted to make a replacement for the battery on my brother’s bike we would have to do more work because we would have to make one up but the bike that had the SC from the factory is a great solution. Totally maintenance free. Never had to touch it. By the time you go to the trouble of adding the extra electronics and some routine to keep the battery charged so it does not discharge when you don’t use it then you may as well ditch the battery put the SC and be done. It will last the life of the bike. The bike will be too old to be worth keeping it before the SC will need to be replaced. And also the SC is smaller and lighter than the battery. Not because of energy density but because the battery needs to have substantially more capacity to ensure you do not run it flat by mistake and to make sure it will not go flat between rides which is probably why they used a SC in the motocross bike in the first place. The SC in this case is a far superior solution. Replacing it with a battery would be stupid. It is a solution that has worked flawlessly for the last 7 years and will continue to work for at least another 10 by which time the bike will be too old to keep running. By contrast the other bike went thru 3 batteries In only two years. Every single dirt bike I know of that has a battery has had to have the battery replaced more than once in 2 years. The common cause has been from running flat by not riding the bike often or stalling it too many times and running it flat trying to restart. I am sure some have also died from overheating. A few have been the expensive lithium replacement batteries and they don’t last any longer.

    Dear friends, Super capacitor is very good for energy storage as well fast charging and high current supply capacity. It can fullfill high current demand and receive regenerative braking better than other storage steup.
    These properties of supercapacitor make non-user friendly and safe.
    Everyone talking about fast charging but can anyone has considered capacity of charging station. A vehicle will need same energy to travel a particular distance and that amout of energy to be recharged either in few hours or few seconds 10kWH supercapacitior or li-ion battery ( efficiency considered same) may need 720000 Amp current capacity for a second at 50V or 20 Amp for 10 hrs. Whatever fast charging, energy needed will be same. What will be condition of connectors for carry 720thousand Amp current. Similarly in discharge of @ 1 lakh Amp for 10 second will be like numb highly dangerous to life..
    Dear experts, What will be your primary choice between mains power and storage power?
    There are some limitations in supercapacitor use in public areas and were unable to replace fuel vehicles.

      Except energy density is in the next to useless for transport use. There’s a critical wh/litre volume they need to reach to be useful. Since they should be extremely light weight, energy is always in volume unlike batteries. 50 wh/litre is where the Graphene need to be, none are except the Swinbourne BEST polymer graphene supercaps.
      Maxwell are one tenth of this.

        This not reply of point raised. If charging station having capacity 10kWH, so whatever fast charging Supercap of capacity 100kWH will take 10hrs to be charged fully. Consider transfer of energy from grid to storage

    I forsee the use of supercapacitors in conjunction with storage batteries to power a wide range of EVs. Fast switching and high current electronics will enable a plethora of innovative solutions to both charging and powering EV systems in our near future.
