Super capacitor 500F 2.7V Charge and Discharge Testing 

i have to agree with a lot of the other comments, that the music is not in any way enhancing this video, it's a fook'n educational, informational...

Theoretical Capacity=375mAh Actual Shown=~290mAh Current during charge 15Amps Thank you EasyTech. Sadly, the experiment is slightly flawed, because the meter is not hooked up properly during the charging, so we don't see what goes into the 500F capacitor. Additionally, the poor power supply is dropping way below it's rated 3.3V output, so many, many amps were flying during the charge up. To calculate how much is stored, we can approximate it based on the output power. The motor is just a big resistor/inductor, regardless if the label says 12V. The current out of the capacitor is 2.7v @ 0.30amp at start and slows down to 1.4V @ .25amp (less power output) by the end. The average between the two is mAh equivalent into this motor resistor. If we run for one hour at 2.7v @ 0.3 amps that would be 810mah, however the motor actually ran for 1/2 hour, so 405mAh consumed. At the end of 30 minutes, it was using less power at 1.4V @ .25 amps, so that would be 350mah, but running at only 1/2 hour, that is half at 175mAh consumed. The average between the start and end mAh consumption is very roughly 290mAh used in 30 minutes by the motor and might be slightly higher if the voltage/current drop is not linear. If we calculate the max storage based on the Super Cap Ratings (credit goes to RuggedCircuits over at Arduino Forum) 500F x 2.7 v = Q = 1350 Coulombs of charge. Now 1 mAh is 0.001 Columbs per second (0.001A) multiplied by 3600 seconds or 3.6 Coulombs. So I think the capacitor is equivalent to 1350 / 3.6 = 375mAh (Pretty Amazing and close!!) #Danger Risk#, if you push 10+ Amps into a super cap, it may exceed the max input current and heat up, melt, explode (high voltages) or short internally, check the manufacturer sheet first! If we want to know how much that very sad power supply had to source into the Super Cap over only 1.5 minutes, we again use average voltage of 1.1V to 2.7V over 90 seconds. The power supply was hopefully being current limited during the charging, so that it would not melt internally. The average voltage was 1.9V during charge and lets assume 375mAh went into the Super Cap, which is the calculated rated max above. That would be 60min / 1.5min total = 40 times more than the one hour capacity went in within 1.5 minutes, which works out to 40 * 0.375amp/hr = 15.0 Amps exactly. That is a lot of current from the poor power supply!!! The total power into the super cap was likely 1.9V x 15 amps = 28.5 Watts instantaneous Hope this helps. If people repeat this, consider adding a power resistor between your charger and the SuperCap, so that neither your charger nor the SuperCap die. A number to keep the current below 3.3 amps @ 3.3V would be a 1 Ohm 20Watt Power Resistor in series

The music is very annoying, much too loud and the spoken text is impossible to follow!

A lot of critics out there. Nice job Easy Tech. Keep up the good work.

Background Music is distracting my attention and I am not able to listening what you are saying properly. By the way nice informative video definitely worth of hitting a thumbs up

Very helpful bro thank you so much bro

Great full information u shared sir nice for exploring it talent practically. Sir my 1 question is - 1)How to measure the capacitance of the capacitor if the readings are not given on the capacitor without using multimeter??? 2)How to measure the voltage in the AC 's (home applying current)???

If you turn the captions on, this is just insanely funny! Thank you for the video. I have to pick one of these caps up and play around with it.

Nice experiment

super expt. bro tq

Wow lasts for so long!

You are the best

Nice video 👍👍👍👍

thank for your vidio

That was a huge vibrator motor! Lol!

Please modify your video without any background music then re-upload.

Nice

is there any pbm when we are charging with 3.3v input...?

What if u leave the 6 capacitors always connected in parallel with battery? you ll never have to worry about car not starting?

Super bro

Super Kapasitor Elco 500F kuat sekali SahabatQ ❤️👍👍👍🙏🙏🙏

What is the name of that song playing in the background?

background music is too loud. please tell me the spec of the motor you used. i couldn't hear

nice informative video..but you scared me with your music

Increase current please. May be 5A. This is 500F not 1000uF.

Kya super capacitor par soldering karna safe h ya fir usme risk hota h . pl. Tell me . I want to make power bank with it

This motor voltage and amb?

I'm new to electronics. What is difference between normal capacitor and super capacitor?

What is the input voltage and current given the capacitor during charging... for the smps

Can I charge 12v 20ah car motorcycle charger on that thing?

esse full charge karne per power bachup time kyaa hogaa

i have 6x500F supercapacitors in series on board and i want to build a Lead acid replacement for my 4cylinders 750cc motorcycle. How should i connect 6 x18650 batteries i have, to charge the supercapacitors? Thanks!

What is the link to the music that we heard?

I liked what you were presenting but I did not care for the music or the constant changing of the volume.

Hello! If the capacitor do not keep the charge is faulty? I change the capacitor with a 18650 lithium battery. Thank you

Está escrito certo? Capacitor de 2,7v por 500F ??????

12v motor and 2.7v capacitor wah

That ammeter, is that battery operated?

Congratulations ! You just have proof to whole world as your music taste is disturbing questionable...

So 5 of those in series would get you 13.5 volts. Another 20 of those (25 all together), 5 sets in series of 5 parallel would get you 13.5 volts, 5 times as long. As long as the drop is the same as that motor. Thats not bad.

How check esr using ossiloscope of super capacitor

What was charging current...

what difference 500f with 500uf, 500nf 500pf. If 500f more 30minit. How about this 500uf, 500nf 500pf

You charge and measure only with one pair of clamps. shouldn't we see the voltage of the power supply instead??? i don't get it...

Wat kind of motor you use????

What is the name of the music that we heard

What is prise of 2.7volts500f

note that the ammeter is not giving proper amps ....... i charged mine with 0.2A @ 2.5V and it took around 2.5 hours ...... so more current is needed to charge it

How much amp you will give to charge the super capacitor

Amp/sec doesn't make sense. Farad is Coulomb per Volt, so F*V is equal to Coulombs, not A/s!

is capacitor ko 12v DC motor se charge kiya jata hain, plz comment kijiyea

what is charging currant.

Please help, I need the charging and discharging curve of a super capacitor of 3000f considering the charging amps is the same as the amps drawn by the load and same with the voltage

Hi, I am from a computer science background and I don't have much knowledge on electrical and electronic things. I have drone which was built by assembling all the drone essential requirements. I have a battery which is 5200 mah, 11.1v 35C. I think I can continuously fly the drone for 10-15 minutes. Now I am thinking of another power source , which is tethered drone. I don’t mind drone tethering I have an idea in my mind to build the tethered drone. I am not sure whether it will work for me or not. Please help me on that. On the Ground I use AC power supply which is 230 volts and use some 14 - 22 gauge wire for 100 feet and at the drone end convert AC 230 volt to DC 12.5 volt. I mean some kind of adapter(AC to DC , 230 volts to 12 volts 1 amps) I will use. Now I am worried about is the amps which is required by the drone motor. I have a 180000uF 50V Electrolytic Capacitor which weighs about 700 grams. So when the capacitor gets charged from the source side and discharges at the other end. Will the discharge side able to run the drone motors? Please help me on this. And I also have some super capacitors, Can I use those capacitors. I am providing you some link on the capacitors which I have already purchased. www.electronicscomp.com/180000uf-50v-electrolytic-capacitor-pg-garde-india?search=capacitor&sort=p.price&order=DESC www.electronicscomp.com/1.5-farad-5.5v-super-capacitor?search=super%20capacitor

2.7v500amp super capistir ka kya rate h market m ye to baitri ka kam krega

Intha capacitor Enga kitaikum please . How much

what is charging voltage

What practical use can you do with that capacitor?

How much prices bro....?

How Much is the Charging Power?

How many amps these capacitors hold?

Connect a joule thief circuit!

Charging votes???

The music too loud, the phone timer isn't necessary because you can just turn off the power when it reaches 2.7 volts as written on the cap. Also SPEAK UP, we cant hear you over the music which isn't even necessary.

1capacitor ka price kya hai??

the motor run test must be done with some load to determine the actual run time this test is inconclusive

From where did u purchased this cap??????

Which is capacitor rate

Учёные высчитали, что ёмкость в одну фараду имеет планета Земля.

Quase uma bateria 👍👈

From were does the energy comes from??? You fill it with 200mA in 1.5 H and refill it in over 30 houres with 300mA. Fake or?????

tụ sao nạp điện lâu như ac quy vậy .

Price kitna h

You are charging at only 20mA>? why>

Supper capis48volt 1000 each prize

How moch prize

Sir, I need 25v or 50 v 4700uf capacitors in bulk quantities. If you are having the same please send me the prices, if not please send me the address of the suppliers n Mobile immediately

Bro how much price...?

i don't UNderstand When I Connect a 25V Capasitor to a 20V Step up Converter The Capasitor Charges up to 20V Instant!

I think motor shaft is bent

Your background music is too loud to understand your LOW speech volume

Hmmm. How much amps do I need to charge? you don't mention that.

I don't understand why there needs to be music in these videos.

I need for the capacitor

why need to background music

CEPASITOR

Music loud and irritating

Where I can buy?

Said.muwgik..apande

RS775 is a 12v dc motor a 2.7v capacitor can never run that motor

Is crap music drowning out the voices compulsory for these types of video?

1 capasater rate

Terjemahanya kacau😆😆

Almost unintelligible; unfortunately too difficult to watch with the so-called distracting music.

Why the music, thumbs down.

FAKE VIDEO banaya hai dc12v volt ki DC MOTOR 2.7v dc pe chal rahi hai.

bod bod bod bod bod ... even we don`t listen because he keeping the music so high i think he want do dancing not talking about the capacitor

I'm sure ir's fake
