Cranking a Car with Super Capacitors (Supercap)
HTML-код
- Опубликовано: 13 июн 2016
- Supercapacitors can deliver a lot of power. But can they crank a car? There is also some good information on cranking current and behavior good to understand J1113-11 standard.

"No no, this expensive, I careful" haha pure gold 🤣
And the very next thing that happens is that he burns himself when shorting one. I guess the capasitor was fine but he still wasn't careful
Krizseiger 2002 that was the joke
Can’t say the same about his daughter
Hahahahahahahahahahha

- Are you okey?
- YEES
Thumbs up for ElectroCUTE
The channel name is murder.
yes, adorable, lets hope she doesn't inherit her dads uni-brow :)
The kid got sulphuric acid on her hands and then wiped her eyes. The hospital did eye surgery because the government subsidizes those procedures and the crooked doctors took advantage of the situation. The complexities of the operation caused them to remove the surrounding tissue. Now, we'll never know if she'll inherit the unibrow.
+Kirk Nelson lmao
darker than...
3:37 he was obviously talking to the scope
omg lol
Yeap
lol good one
Lol
3:33
I'm just impressed how well ElectroCUTE follows instructions. She held the contacts exactly as told and just watched that scope fall.
Now he can show her all the times he failed so she knows what not to do. Edit:Nevermind, she has nearly 45k subscribers. Now if the stupid RUclips Kids crap wasint in the way, we could appreciate Electroboom touching something and getting zapped while she evily laughs in the background.
"Can you digest that? Of course not, its filled with chemicals" Does anyone else notice this genius???
TheJoker1432 *I*
I like how subtle it is. If you zone out for a moment you will miss the joke completely.
Dang, I didn't catch that at first :P
they're like dad jokes and cheesy science jokes rolled into one, yet still comedy gold lol
TheJoker1432 hell yes
When you sprinkled the hearts I lost it! LMAO.

Your comment like is now 666, coincidence?!
4:43 RIP that one heart that fell into the engine...
F
"into" the engine
It fell into the engine bay and is easily retrievable. If it fell into the engine it could start some major damage

I didn't flinch at the first jump scare but when the scope started to fall I tried to catch it though the screen and had a heart attack
Same here!! ;-)
good to know I wasn't the only one
I put my hand in front of it touching the screen in a quick reflex, i guess when you work with these things and know how valuable they are and how easy they break you cant help it! hahaha
those things are $15k...
You know, it's not easy to take God and shove him in a plastic box and give him a touch screen. Or to make it ooze with power.
*starts the car* "Are you ok?"
"YEAH"
I like how she barely blinked when the oscilloscope fell off and Medhi started cursing. She's clearly familiar with her Dad's work habits.

03:25 ElectroCUTE understood her assignment and decided to stick with it at any cost 🤣🤣
"Can you digest that? Of course not, it's filled with chemicals."
I hate and love you at the same time.
"Oh, you thought this cap gonna blow, oh no, no, this expensive, I careful!"

I love ElectroCUTE's surprised face at 4:13. She's picking up her actress side.
I never really noticed it and watched it again after seeing your comment. That is pretty good acting for a kid! The raised eyebrows and then the slow head turn towards her father.
He should do more video with her she is cute
"Expensive." Buys six
Anything for his experiments
Those are 25$ each on ebay. They're expensive compared to regular capacitors.
That sounds exactly as me. :)
that oscilloscope is 15,400$
Well, he is an electrical engineer and probably uses it all the time, so good investment for him.
4:28 That's why the manual says disconnect the negative first.
1:14 that jump scared me so hard I almost fell out of the chair
"Coincidence? I think not" lmao

Pure gold. One of the best videos -- From ElectroBOOM and on RUclips. Only better one I can think of is maybe the one about Graphite's properties. Would love to have him as a teacher :)
lmao. ElectroCUTE. That look on her face. You crack me up man.
That name was provided by all the comments on his other videos haha, he finally adopted it
dan428 Hahaha. That makes it even better. XD
thats a cute nickname...
or does he CRANK you up?
his wife shocks him way more than actual electricity😂😂😂😂
1:48 probably the most satisfying wound in yt ever
Thank you for such informative tests. I did notice that the original battery supplies a higher cranking current and a shorter time in startup the car when compared with the ultra capacitor setup. The first peak of the cranking current should correspond to the current when the engine is stationary and sub-sequenced peaks would correspond to the compression stroke of the engine. An 4-cyclinder engine would have one compression stroke in one revolution. It seems the engine starts after 3 revolutions with the original battery and 4 revolutions with the ultra capacitor setup.
I did use an commercial 300A batteryless (ultra cap) jump starter to start an 1.8L gas car and obtain similar results.
1:21
I was expecting the cap to kiss back and discharge all its current.

Thank you for existing, I really enjoy watching your videos
Thanks for showing the scope images of the cranking load. I never got around to doing that myself 👍
I love the part with the 13 and 666. "Coincidence? I think not." And explains with the formula :D 0:58
666 💀💀💀

you and your uni-brow deserve a shit ton more subs!

Thumb up for the helpful and informative demo. thank you ElectroBoom.
"can you digest that? of course not, it's filled with chemicals." i am dying hahahahah
Great job Mehdi, another entertaining and informative video!
A hero of a engineer that hurts himself to make his science videos appealing for all ages. Thank you for your service Mehdi.
I just go through all your videos and hit like. Awesome.
3:16 ElectroCute has that look my daughters have in pictures of us when we are doing something way coool.
That is the "try not to smile too Much" smile
"Can you digest that?.. Of course not, is full of chemicals!" LOL..
ElectroBoom is frickin hilarious! I really enjoy your videos!
Bro you are one of the smartest/funniest people I have ever had the pleasure to watch
The thing about this guy that is so SO great is that he is consistently hilarious in new and original ways in each video. To be fair also hilarious in familiar unoriginal ways ways too *cough* electrocuting himself *cough*
You, sir, deliver what's expected every time!
You have one of my favorite channels on RUclips, and you might be one of my favorite humans, ever.
Amusing! In my day, getting a cap to start a car was unheard of. We all knew it was possible, but knew it would take a warehouse filled with the things.
really wished you uploaded more often :c still enjoyed seeing another video!
0:33 xD the best line i have ever heard
I'm glad someone else caught that, so smooth.
Anti-joke at its best xD
Can you write what did he say please? i didn't understand
The Butcher He said "can you digest that?", which is another way of asking if you can understand what he's saying
He then follows it up by saying "Of course not. it's filled with chemicals", taking the literal meaning of his previous statement
+d3athblad3 Thanks!
0:24 when you are making a video without your mom permission
Man, that was one great video! Your humor and facial expressions were awesome. I wish I knew just a fraction about electronics as you. Keep up the good work.
Why didnt you use a FULL BRIDGE RECTIFIER ?
Damn, I read it with his voice in my head :D
Exactly, it can not be unheard :D
Because a lead acid battery outputs DC VOLTAGE. FBRs are used to "rectify" (convert AC to DC) voltages
You just have to ruin all the fun dont you...
Thor Wald Seems like he is used to it :\
He is not only a good engineer but also a very good actor and advertiser 😀
Your family is really very supportive 👍👍
I don't know anything about electronics, but whatever you're doing sure does sound cool. Love the comedy!
keysight oscilloscopes are the only ones that have nice colors for the channels.
Thanks!
If you could sell some to the US Navy that would be great......

What a cute assistant! I love that he’s such a good dad
Your assistant? nice, didn't know that underage employment was legal in Canada.
Yeah, they call them children here
lmbo you mean. Children read this stuff.
Go ahead and moo for us like a cow
I figure they have the same loopholes they have here in the states. Close relatives are exempt from some of those restrictions in family owned and operated businesses. It's how Chinese restaurants get to employ their kids for simple tasks like processing pea pods.

Well at least I pay my daughter for her work. She usually asks for toys though instead of money... need to develop her financial sense!
ElectroCUTE: *builds robot* "Daddy look at my robot."
ElectroBOOM: "Cool. ill check it out when i wire up this light *ZAP* OWW [BLEEP]"
First time watching his video and my mind just overloaded!
Thank you @ElectoBOOM
This is old, but I think the bigger question is if it makes sense to run the supercapacitors in parallel with the car battery to help with cold starts and extend battery life. Though the capacitors would actually cause the battery to drain fast if you didn't use the car for a week or something. Maybe a shut off switch to disable them if the car battery drops below a certain voltage?
"...can you digest that? Of course not, it's filled with chemicals."
ElectroBOOM has some of the funniest minutiae in his videos. Right after he burns his finger, the next scene flashes "A few days later..." for the briefest of moments... but it adds so much humor to the video!
I've had a good laugh and learned about supercaps and scopes. Well done.
"With 400x more charge, Can you digest that? Of course not it's filled with chemicals." hahaha
Wiring super-capacitors in series without balancing or management is generally a bad idea. Because of the difference in series resistance and capacitance variations, not all caps will charge to the same voltage. This can mean that if you charge your bank of 6 caps to 12V, not every cap will have 2V over it. Some will have 2.2, some 1.8 etc. You can imagine this forms a problem when you are pushing it up to the theoretical maximum (6x2.7V) or with bad caps.
When designing a capacitor bank for a hydrogen vehicle dc dc boost converter (20x2.7V in series, so 54V in theory but in practice limited to 49.5V) I have seen variations of up to 0.8V(!) between caps.
don't worry, he sometimes learns from his mistakes
I know, he knows what he is doing most of the time :) It was more a note to people wanting to copy him without knowing what they are doing.
How do you balance your capacitors?
There are two main methods of doing it, active and passive balancing. In passive balancing you just waste excess power by having a mosfet in parallel to each capacitor that dissipates power when the voltage exceeds a certain threshold (can also be a relative voltage to other capacitors).
Active balancing works by having a DC-DC boost converter in parallel with each capacitor. When a capacitor exceeds the threshold, the converter is turned on which boosts the voltage up to the capacitor bank voltage and dumps it back into the capacitor bank.
There are some more methods and variations on the above methods but these two are the most common ones.
It depends on the application which is the most efficient/cost effective. Generally the first is the cheapest to implement in the short run, there are even dedicated chips for this.
+ultort
If your caps are all the same (and preferably even from the same production batch), you can get away with putting a high value resistor in parallel with each cap. Of course this will slowly drain the caps as well, but depending on your application that might not be a problem. You could also put diodes in parallel, for example several silicon diodes (in series). Just select the forward voltage of the diodes so that they will start conducting when the voltage on the cap would exceed its limit.
You are the best comedian/teacher in the world even i learn something every video
Alright you earned the like with that scope kiss with hearts.

I like that when he put the kid to act "So you weren't sure!", it wasn't just the final reaction, she also acts surprised earlier at the moment he says "I suspected".
dude you are amazing but please make more videos
Thanks for the video and my special greetings to your super-charming assistant ElectroCute!
Is there a protection circuit recommended when using a supercap array as a starter?
You have the nicest test equipment
Your videos are extremely entertaining
3:20 - Haha, yeah, he's not gonna do that!
3:26 - O.O .... I guess he is raising his kid to be fearless.... O.O
