I love my maxwell super capacitor. 1800 cca it lessen the heavy draws on my batteries. Let the capacitor do the cycling. Like bass hitting on a car stereo. Add the super capacitor and your headlights don't dim when bass hits. The hard cycle is not placed on your battery. I couldn't run my skill saw all day off the solar and lead acid batteries without the super capacitor. The charge time is great within minutes of sun rise and I can be sawing. I use mine more as a soft start. The car stereo is the best way I found to explain of how super capacitors fit in and work. I believe they help extend life of batteries and other solar equipment. You might have one in your car if you have a big amplifier.

Like others have pointed out, using this tech for regen braking is the better goal in mind. A lot of energy is wasted in regen braking because you can't charge the battery quickly enough, but to capture all that energy in an ultracapacitor, and then, release that energy to accelerate would make a pretty dramatic difference in range. Then, the battery can just be used for cruising and operating all the instruments.

The problem with using ultra-capacitors in passenger vehicles to assist in capturing energy from regenerative braking is that they take up too much space. And they add some weight that reduces range, although that might be cancelled out by the additional energy that can be recaptured by regen braking. But the space needed to have them in enough quantities to make a difference is not negligible in passenger vehicles. They might make make sense in electric vans or other bigger vehicles if the cost isn't to high where there's a foreseeable return on investment.

@android04 2 роки тому

@@buildmotosykletist1987 On Model 3 you want regen and the capacitor voltages to be around 384V in order to be able to charge the battery pack. Skeleton Technologies SCH3400 ultra-capacitors are 2.85V. We would need 135 in series to match the voltage (could do multiples of 135 to increase storage). Based on their datasheet, 135 of them weigh 71.55 kg and take up 52.65 L of space (that's just the capacitors with no threaded posts and no electronics needed to manage them). That's 157.74 extra pounds and 1.86 cubic feet. As for the energy storage capabilities, the math on that is a bit more complex because a capacitor's voltage drops as it is discharged and if their voltage drops below a certain amount above the current high voltage battery pack voltage, it won't charge it. You also have to take time into consideration for those calculations, and regen usually lasts from a few seconds to probably not more than 10 seconds.

Dad died and I wasn't able to complete the application. Basically I used a 1-1/2 volt cell battery to fire a 1967 Chevy starter solenoid via a capacitor controlled by a resistor. The 555 timer allowed me to change the rate of charging the capacitor so that it would open the drop doors to the hay feeder, every day or every other day. in the interim of charging on the road.

Fwiw, the start up of most electric motors above the US 110 volt standard is accomplished with capacitors already. These "ultracaps" may reduce the size of the current ones but not make any impact on energy consumption. What this could do for EV charging times would do much to shorten the days before the electric auto is thoroughly on the ground. Further, using them to help with momentary spikes in power demand would go a long way toward making renewables like wind, solar and geothermal a better fit within out existing systems. No matter what we do, Big Oil and Big Utility aren't going away- engineering to better use renewables matched with the resources of those entities is the shortest time frame to the goals of 2030 and beyond.

@matthewhuszarik4173 2 роки тому

Where Ultra capacitors would benefit BEV is in the longevity of the battery. Rapid charging and discharging batteries builds up heat in the battery that damages it. If ultra capacitors could eliminate or at least minimize those surges this damage to the battery could be greatly reduced. It could also allow for a significantly reduced cooling systems. They could also allow faster charging of BEV you rapid charge the battery to 80% and the ultra capacitors slowly finish charging the battery.

Semiconductor efficiency is running into a hard limit in silicon based transistors. A lot of the improvements in semiconductor performance came from shrinking the transistors so they use less power and can operate faster. But further gains are becoming harder and harder. Current most modern components are manufactured at a lithography of about 7nm varying on the manufacturer. You can get that to 3, maybe 2. The improvements from that are not that big anymore and beyond that it becomes really pointless. With graphene semiconductors can be built a lot smaller and they can be more efficient too. Graphene coated Li Ion batteries might increase battery capacity by quite a lot, also reduces the wear by a ton. There are so many applications for Graphene once we figured out how to mass produce it costeffectively.

Very nice presentation, thanks for your input. I'm using EDLC super capacitors in my projects from 2007. They help the battery, which has great capacity but high internal resistance and they last for years. First ones had a tendency to leak. Also their rated voltage is low, about 2.5 to 2.8V. So there must be at least five in series for 12V and they must be balanced. Since their principle of working is electrostatic, they have completely different charge/discharge characteristic then batteries. So their usage as a main power source isn't very plausible, but together with batteries is where their synergy really comes to life and is very useful. I look at graphene capacitors as a next step in evolution, mainly getting smaller and more power dense. Definitely a way to go.

@rcpmac 2 роки тому

@@bnjmnwst Dr Yiwei Sun, lead author of the study from Queen Mary University of London, said: "Graphene owes its thickness to an array of chemical bonds sticking out above and below the 2D plane of carbon atoms. Hence graphene is really a 3D material, albeit with a very small thickness. "By applying conventional 3D theory, which has been used for around 400 years, to 2D materials such as graphene, which have been known for 15 years, we show that similar arguments apply to other so-called 2D materials, such as boron nitride and molybdenum disulphide. In that sense, 2D materials are actually all 3D." Graphene is often called the world's first two-dimensional material. It was discovered in 2004 by peeling off graphene flakes from bulk graphite (used in pencil leads and lubricants) using sticky tape. It is regarded as part of a new class of 2D materials and it is currently modelled by scientists as a sheet of atoms with very little depth, hence the name 2D material.

From past presentations for the supercapacitor for battery storage, I thought the main benefit was the length of time to charge was instantaneous, as compared to chemical stored batteries. This would be very impactful for Electric vehicles where the wait for charging is a major disadvantage over filling up with gas. My understanding of the problem was that they also discharged instantaneously. Without strong engineering knowledge, I thought it would be possible to have many supercapacitors that could be charged instantly and consumed in series, just like gasoline that has the energy density that is released instantly when the spark ignites the explosion. The higher the power requirement, the more of the stored capacitors would be consumed. It is great to see these new possibilities. Thanks, Matt, for keeping up on the latest developments.

@chrisjacobsen1659 2 роки тому

Physics of conductor sizes and connector design dictate the current and voltage you can charge something at, whether battery, or supercapacitor. We probably won't be able to build the infrastructure everywhere to be able to charge a supercapacitor car "instantly" as that would require HUGE currents or voltages to push the energy a house consumes in 3 days into a car. If you can wait 5 minutes from empty, then that would only require an average charging of 1000V at 500A. Something we can definitely do. But from there it starts to get a little crazy, 2.5 minute charge would require double the 500kW 5 minute charge of 1MW. Yes 1MW, that's on the order of power generation stations today. Double that to 1.25 minute charge and that's 2MW, or enough to power 1,600 homes. Let's keep going, a 45 sec 0-100 charge would require 4MW, 22.5 sec 8MW, 11.25 sec 16MW, and finally just under 6 secs would require 32MW, in other words, a direct connection to a small-medium sized power generating station. I could settle for 5 minutes.

It's not instant but thats mostly due to the limits of what can be transmited down a conductor safely (as in not making your wire catch fire) If you can get enough conductor capacity yes you can top off a capacitor in seconds although its a balancing act of what is practical to do. There's also the issue of energy density. Lion batteries that can power an EV for a couple hundred miles can fit under the floor/seat of the car. To do the same with super capacitors you'd need to be towing a trailer to carry them. Chargeing it fast would also be a strain on the grid. It would probably require haveing a bank of super capacitors at the charge point that charge off the grid over time and then dump it into your mobile capacitor in a minute or two depending on the current your conductors can handle.

Just gulp down a 20-second charge at certain selected stops, use regenerative braking, and you can do it all without wires! It would be a great solution for Washington DC, which explicitly forbids overhead wiring in the downtown area, but dreams of having some tram lines there. Alternately, they could wire up only very short runs of overhead wire (just a block, here and there), have the bus/tram unfold its pantograph, and gulp down enough electricity to charge up the capacitors on those short runs.

I have been invested in GMGMF since may so take what I say with a grain of salt but the CEO says that their technology will bridge the gap between battery and super capacitor. They also have a proprietary method for making graphene from methane which is cheap and can be done at scale. That also means you can used these batteries as capacitors to charge cars at accelerated rates. Just trickle charge a battery at a charging station off the grid and then output the charge to the car at 3 megawatts. Then you can charge your car to full in 10 minutes. No more range anxiety. That is just the start of the potential applications of this technology. If they are able to scale up to grid level batteries they could solve the problem of excess generation from renewable sources. Depending on how their technology scales it could end up making both lithium ion batteries and super capacitors obsolete.

Generally when you want better conductance for a wire: you just go wider. It's only when that's impractical that you consider upgrading the material. Whilst graphene beats equally thin copper, graphite isn't flexible enough to make a good wire. And it needs to be graphite because it needs to be thick. Side note on graphite's conductance: it matters how you measure it. It's much better going parallel to the layers of graphene than going perpendicular to the layers. That's true for both its electrical and thermal conductance. Some of the stuff i found while researching graphite wires after reading this comment seemed to not understand that nuance A related option, though, are carbon nanotubes. I haven't researched them thoroughly but it does seem some people are looking into using them for wires. And i don't see any reason they couldn't beat copper.

Watching this video I see a possible application for ultra capacitors in race cars for regenerative braking. Right now the EVSR doesn't generate much electircity during regenerative braking because the braking intervals are short and intense. For example, at Thunderhill turn 10 (bottom of the downhill) I'm on the brakes for less than a half second, the batteries can't absorb a meaningful amount of electricity in such a short time, but an ultra capacitor perhaps could. If the capacitor could then be discharged to the motor while accelerating out of the turn then there could be substantial efficiency gains.
