    Super caps will very soon replace batteries. The issue has been internal insulation and so the voltage tends to be very low. Typical 1.5V per 500 farad cap. That’s 500 coulombs so capable of delivering 500 amps in one second. Multiplied by voltage gives 750 watts per second. If you then divide that by 3600 (seconds in an hour) you’ll get Kwh of around .2 for one small cell. No doubt these will be much larger.
    It’s all about to change. You have also overlooked weight. They are much lighter than batteries.

    I think the new equation will be super capacitor + dry battery and not current Pana battery. Dry batteries are supposed to be charging more quickly more like and hybrid battery+/super capacitor in conjunction with capacitor that will be even better.

The idea might be patentable. I need to meet with people interested in the subject to develop the idea. I will provide more details in further communications. I live in Atlanta, Georgia USA.

    2019 where people with poor science knowledge attempt to explain science.
    Batteries aren't bad at sudden loads and charging they have internal resistance as current flows though them, this internal resistance at large currents causes a voltage drop. First year science stuff V=IR.
    Capacitors are shit at storing lots of energy for a long time because they store the energy as charge and not chemically.

    You call AAA and they show up in their gas driven van and charge you car with their gas driven generator.
    You are NOT going to get "more regenerative braking" you may capture more energy from "regen" however the braking will basically remain the same unless you change the resister which is used to dissipate the energy into heat.

    • Hope4Today9 Now
      Hope4Today9 Now 9 days ago

      @Kirk Summerwill what I 'm getting at is that their two different aspects ... the ability to break, and the ability to capture and reuse stored energy. Yes, you could get more saved energy with better batteries ~ you can never stop faster ie "more braking" with better batteries. It takes four time constants to charge a capacitor. Resistors have no time constant. In DC drives this is dynamic breaking and in AC drives this is pulse breaking. True Regenerative breaking pushes power back into the line ~in industry it's not a clean sin wave. So it really it's just bucking the power being supplied.

    • Kirk Summerwill

      You really would get more regen braking power of the battery could absorb power faster...

    • Javier Hernandez
      Javier Hernandez 9 days ago

      @TheOrganicartist I'm not talking about having capacitors in phones since they're so low capacity. I'm talking about implementing the dry cell batteries that have up to double the capacity and lifespan of normal lithium.

    • TheOrganicartist
      TheOrganicartist 9 days ago

      capacitor + battery hybrid systems are amazing for so many ideas, but mostly for systems that have large fluctuations in power draw/demand, so I don't think it would help cellphones much (because they have a rather constant power power draw). However, if super-capacitors get more capacity, a cellphone with a 36hr high use lifespan using super-capacitors would charge blazingly fast and as long as you aren't away from a power outlet for 36 hrs (remember just 1-2 minutes to charge, and that is likely a massive time over estimate, capacitor charging would likely be less than 60 seconds depending on thermal loads and safety) and THAT would be amazing and i would very much like to buy one. Another idea would be a capacitor pack for a laptop so that if users rarely use it unplugged for a long duration they would have a more convenient charge/mobile use cycle.

      I think the best use of battery + capacitor hybrid systems are for smart home power systems that would learn the household's power use cycle and monitor energy pricing real-time to know when to siphon and bank power at lowcost for future use

    Maxwell makes Ultra Capacitors, not really a super capacitor... so stands to reason it'd be called Ultracharger. Or the Fluxcharger, the Flux Capacitor is a cool name, so a Fluxcharger would make sense.

    Toyota? Vertically integrated?? uhhh maybe in comparison to other car companies but as far as vertical integration goes, most car companies are just about as horizontal as possible.
    Also, a super capacitor cache would be much smaller than 1kw probably

  • papparocket
    papparocket 13 days ago +1

    Commenting on the hybrid supercap/battery storage system, Maxwell's 3V/3000 Farad cell has a specific energy of 7.4 Wh/kg. Thus even a 1 kWh supercapacitor pack would weigh 135 kg or roughly 300 lbs for just the cells. Assuming a 30% pack factor, the weight in the car would be in the 390-400 lbs range. A 5 kWh supercap pack would then be 1,900 -2000 lbs. So unless the energy density of supercaps gets a lot higher, storing even 1 kWh of energy would be a pretty heavy and 5 kWh pretty much out of the question.
    However, I don't think you will need even 1 kWh of supercaps to make a big difference in acceleration and especially in regen braking. Assuming a Tesla 3 with two passengers weighs in at 4400 lbs (1996 kg) is traveling at 60 mph (26.8 m/s), the kinetic energy of the vehicle is only 718 kJ or 200 Wh. Assuming 93.6% kinetic to stored energy conversion efficiency (97% generator, 97% rectifier, 0.5% other stuff) the supercaps would need to store about 188 kW to capture all of the kinetic energy. The weight of a supercap pack to capture all of the 60-0 braking energy would only be 33 kg (72 lb).
    Of course it isn't this simple. If you want to accelerate to 60 mph with just supercap energy, then to put 200 Wh into the kinetic energy of the car you would need 200/0.936 or 213 Wh of supercaps for a weight of 83 lbs. And you are likely to want to keep your supercaps at some mid-charge state so you can at any moment stomp the "gas" or do a maximum regen recovery. Something in the 400 Wh range would likely do and add about 150 lbs to the vehicle. If, as you say, the batteries pack size could be reduced because you don't have to size it for maximum power output, there might not be a net change in the vehicle weight.

    Great observation, though you’re missing a few things about super capacitors. Super caps do heat up when rapid discharge or charge occurs. Second super caps need to have a higher voltage tolerance. When 2 caps are placed in series to get a higher voltage you lose ½ the capacitance, 3 = 1/3 capacitance and so on. So, 5 - 5000 farad caps at 2.7 volts set up in series would be 1 - 1000 farad cap at 13.5 volts. To make super caps really useful they will need to be able to handle 250 volts or more. That would be the next technology break through. That is why they are not widely used now. PEACE

    This year a DARPA scientist patented the first room temperature superconductor, while another scientist created the first thermal diode, or Maxwell's Demon, that uses a supercapacitor to move heat from a cold source to a hot one without expending any energy in the process. In other words, it makes ice cubes at room temperature, without using any electricity. The room temperature superconductor that was patented, is made of relatively cheap materials and leverages nonlinear dynamics, meaning its quite possible to use the same trick on other materials. They basically send a signal around the wire that maintains its superconducting state.

      You can find it at Nobody is really talking about it that much, with everyone holding their breath waiting for the patents to be approved and going cross-eyed the entire time.

    2:21 - "300 Wh/kg". Nonsense. It is about 7.4 Wh/kg. (Not much more than other brands of supercaps, which usually hover around 5-6 Wh/kg). Specific gravimeter energy density isn't the main benefit of the supercaps anyway. The main benefit is very high power density. 1kg of supercaps (which is literally TWO of these supercaps), can deliver about 18kW of power (for few seconds of course only).

    You are deeply misinformed.

    They are probably going to be using supercapacitors in their EV charging stations, to help a bit with a load on a grid. Unlikely to be used in the vehicles itself much. Maybe a little bit, to improve the acceleration profiles and regenerative breaking.

    Maxwell is very well known brand. They are leader of supercapcitors for last 10 years. There are few other big players (Nippon ChemiCon, Mouser, Murata, Skeleton Technologies, Cellergy, etc), but Maxwell ones are actually one of the more recognized brands in this market.
