Fast Charging Ultracapacitors and Supercapacitors using 66.7A LED Power supply 

Jesus, the damn bird.

the parrot did not agree ;-)

That's very cool. I love supercapacitors!

You can charge your cap bank to 12v in a few seconds from a car battery, but make sure you use at least jumper cable sized wires.

Thanks! I will use the light bulb limiter to charge my caps to 5v.

You can minimise your charging time by putting a constant current circuit between your PSU and your supercapacitor bank, set to limit the current to la little less than the PSU can supply. You can do this with a simple transistor circuit using an n-channel mosfet. However, this will require good heat sinking and maybe a fan to cool it too! A much simpler way is to continue your approach with an incandescent lamp. I used 55 Watt halogen car headlight bulbs. Their resistance is low at zero volts - under 0,1 ohms, but rises to a bit over 4 ohms at full voltage. So putting a lamp in series with the capacitor will limit the current when the capacitor voltage is low (and the lamp voltage is high) but not limit it much when the capacitor voltage rises. Exactly what you want! You may have to choose a different lamp, or do as I did which was to use a number of lamps in a series - parallel arrangement to get the characteristics you want. It won't be as good as the constant current circuit, but it does approximate to a constant current circuit without requiring too much thought .I was after a cheap rugged unit that could be used 'in the field' by ordinary workmen and charged either from a car battery or mains in under five minutes. Incidentally running these lamps in a series parallel arrangement means they are all underrun which hopefully means they will last indefinitely! You might also consider buying a bench supply which allows you to set the voltage and current yo want. I recently bought a switch mode 20Amp one for about £130 which does the job a treat. It cheerfully pumps 25A into a dead short! The nicest way would be to modify your 66.7A unit to limit the current to - say - 60 Amps without triggering the overload protection. This would require some reverse engineering of your unit, and a bit of redesign and modification. I have so far been unable to get hold of a schematic for these led drivers which would make the task a lot easier!

Dear happy new year

THANKS

if the LED power supply is rated at lower wattage, will the starting voltage necessarily be higher?

Capacitors have a linear discharge curve. The Harrison Labs (www.hlabs.com or www.hlabs.com/products/fluxpower/) FluxCap tm is a step up high current 50, 100, or 200 amp (all stackable) power supplies that make up for voltage drop in power wiring and will provide much more output from a capacitor since it will provide the full output voltage until the input drops below 11 volts! Also, perfect for dragsters that have no alternator.

Hi! Could you make a test of the capacitor? Charge of up to 14.4 volts, then connect to the car lamp 55W. And measure the time for which the voltage drops to 10.8 volts.

THE PARROT IS MAKING NOISE LIKE HIGH FREQUENCY DISTURBANCE ON THE CHARGING PROCESS JAJAJAJA FUNNY BIRD🤣🤣🤣🤣🤣🤣🤣

hw do i make an adapter that can reserve power for abt 30 min after the electricity switches off

Thank you sir ! do you have some balancing circuitry for each ultracap?

Hey man, thanks for the video it's very helpful! I'm looking at charging a bank of 6 Maxwell K2 Caps and trying to acquire a power source for charging. What is the minimum current power supply you can get away with to charge the Caps?

I'm wondering where did you get the circuit ?

Maybe you could make an experiment with them. You can replace a car battery with it. Maybe you can remove the Ignition wires from your Engine and place the BoostCaps intead of your car battery. than you can try cranking the car as long as the starter no longer rotate the engine. than you should check the voltage of the boost pack. it whould be very interesting for me to know how long a car starter can work with the boost cap's.

Would an inductor not work to prevent the initial high current draw? Once the transient has occurred it would act as a short, meaning the supply wouldn't cut out initially and there would be no need to remove it, or would it have to be impractically large to do any good?

thanks to the power of "constant current circuit". i hope you know.

sound cool )))))))))

I have been searching for a comprehensive evaluation between lead acid batteries and a bank of capacitors of the same Amp Hour rating. It seems to me (example): a 100 Ah lead acid battery should be equal to a 100 Ah bank of capacitors with the difference being weight. Next: Why do I see capacitor users charging their capacitors independantly from their vehiches? Does this mean the vehicle's alternator (while driving) cannot recharge the capacitors? This far, I cannot find a video ditectly engaging in these comparisons.

So those balancing boards won't be damaged when charging a bank at 200amps? They just might not be able to drain the higher voltage caps fast enough correct?

I am a student working on a project using supercapacitors. Can you explain why the initial charging required a light bulb? I didn't understand what you said in the video. Thanks.

Use nichrome wire (e.g. Constantan etc.) as a current limiter instead of light bulbs. It's dirt cheap and you can easily have any resistance for a particular need by cutting the appropriate length: 1m with 0.1 thickness is 170 Ohm, 1/2m would be 85 Ohm etc. The lower the resistance of the limiter the more efficient the charging. Power supplies are happy with very little resistance, a 55 W load is way too wasteful. I used to experiment with 0.5 Ohm 500W etc. beefy resistors but they need heatsinks and stuff. Whereas plan nichrome works the same and you can dump it in water for simple heat dissipation. Or leave it in the air, its what toasters use anyway.

I have a question to ask

Excuse my parrot :D

Isn't better/easier to get current limiter ?

after full recharge can you short these caps? to make sure there is enertgy storage .. lol

Hi. What are you using these ultracapacitors for? Where did you buy them and the balance board? And how much?

Bom dia amigo percebi q vc eh BR pelo seu azeite kkk!! Onde vc conseguiu esses capacitores?

That's not a parrot, that's a fucking banshee

dear Billywhizzy, well movie! pls let me know where to buy 3 balancers for the SuperCap. I got 6 pcs of the caps. Charging w/o balancers by regulator is ok, but I would be like to follow the rules:) thx in advance. Karol

What kind of beast do u have in that house ????

From where did you get the capactor bank?

How much did the super capacitor pack cost off of eBay?

it seems that the same as our company

我買500F黑色超級電容充飽2.7V不到1小時自放電為2V左右，過一天 只剩下1.5v左右在過兩天0V是個重大缺點!

where did you get those caps?

I have 6 super capacitors. Each are rated at 2.85 volts 3000 farads. They are completely discharged and I'm unable to charge them using a SKYRC iMAX B6 mini. I will buy a light bulb soon to try charging. What settings do I use on SKYRC iMax because mine can't be adjusted on the fly...I think? I have multiple volt settings 2V, 4V, 6V, 12V... I'm guessing 12 volt if I use a 12volt bulb. The max amps the charger is capable of is 5 amps. I'm looking to charge each super cap to 2.4 volts x 6 to equal 14.4 volts which is the voltage in my car. After I charge them to 2.4 volts each they will be assembled or is it simpler to charge the whole bank like you did. I do not have balance boards and probably do not need them because I'm not exceeding 2.85volts. After I successfully charge the capacitor a bit can I use a EVERSTART 750 Amp Jump Starter to fully charge the caps so it will be faster?

You could use a vehicle alternator too, right? 6 caps in series can handle 16.2V?

Dear lord why do people have birds as pets.

That is a bird ,,,, lol

free that poor bird

Yor bird es sachs dud.

you have tryng discharge time , i thing is very fast

ياعمي صوت الببغاء صرع 🍌

stinger

Most of all, I've leaned to never buy i bird

Unwatchable
