I was a SONAR technician like 35 years ago and was taught at college that
electrolytic capacitors are subject to short circuits so they need safety
circuits but when fully charged you might have them explode as you drive
down the bumpy road in the middle of nowhere. sort of like those airliners
are doing lately.

Energy = 1/2 x C x V x V = .5 x 350 x 2.5 x 2.5 = 1100 joules
W-h = 1100 / 3600 = .3 W-h
6 batteries = 1.8W-h.

I don't know what it takes to start a car, but let's say 500A. 1.8W-h would
supply 500A for .003 hours or about 13 secs. Plenty of time to start a car
(even if it's 1000 amps). If nothing else, I would say parallel this with
the cheapest lead-acid battery you can find, so you have both sufficient
storage and instantaneous starting energy (that won't go away if it's cold).

Battery manufacturers rate (usually) by cold cranking amps, not by W-h. I
think a typical car battery is rated for 50-100A-h, or 600 to 1200 W hours

Interesting. I would point out that putting capacitors in serial doesn't
necessarily mean that the voltage will divide evenly. If you go over the
rated voltage of the caps you'll kill them. You may want to find smaller
capacitors rated for 18V and parallel them.

Автор Eduardo Donizette da Costa Júnior ( назад)
Nice video. Just one quick correction, you don't have 350F there, when you
install capacitors in series, you get double the voltage and half of the
capacitance. Which means that now instead of 2.5V and 350F, you have 2.5 x
6 = 15V and 350 / 6 = 58.33F. Which stills pretty good by the way. Can you
make a video trying to start the car a few times in a row? With the coils
disconnected or something, to prevent the car to start-up, just to see how
long the caps are gonna last. Thanks!

Even if this is real , nobody should use this mod.The reason has to do with
Even if somehow there are capacitors that can start an engine , we need
power supply in a case of an engine failure or when we change a tire. We
need power for the alarm lights for the brake lights , for the horn and for
the head lights .
This pack(if it is real) can provide a huge current(as claimed) for a few
seconds in the begging.Then it is getting charged again , but what will
happen if we need to stop the engine with the alarm lights on for 3 hours ?

Who here believes this is working? The cranking motor in my car needs over
300A for up to 100ms and then around 100A for up to 2 seconds. These caps
(charged to 12V) are completely empty after less than 100ms while trying to
deliver 100A. This is stuff that kids learn in the 9th grade!

Автор John Hlavaty ( назад)
If you isolate the capacitor from the drain caused by vehicle's
electronics, the loss should be near zero.

Автор Victor Chan ( назад)
My car needs a 300 Cold Crank Amp battery. That is battery will discharge
at 300 Amps for 15 second while the battery voltage stays above 9.6V. No
caps can delivery that kind of power! This video is unreal!

if you want to burn your car, you can put the big capacitor in your hot
engine zone, the capacity will burn if over charge or over heat, the
electronic circuits of your car will short quickly because capacitor absorb
too much power of alternator.

Really cool stuff! played with big (for the time) capacitors when I was
younger! I can see this working for cars that has no alarm system, no
leaking current drawn and so on... so for some cars this this obviously
works as you shown... the car I'm driving now it would work, but the 5 I
own before it would not be a good solution... but with some wizard
circuitry and a lithium pack I would be an OK replacement I guess for most
cars... it would actually save fuel by weight and smaller alternator...
cheaper? for consumer maybe but probably not for manufacturer and there is
the problem I guess... Btw next step is a huge (bigger with slow
discharging circuitry) capacitor bank that charges up with regenerative
braking... then your all set and you can wave that battery good bye
forever! :-)

The part that's super-hoaxy about this is the radio part. I hooked this
exact array up to an inverter which then powered a 10 watt speaker playing
some music. And the caps lasted about 2-3 minutes by the time it dropped
from 15 volts to 10 volts. I haven't bothered to try starting a car with
this array... But I feel the OP isn't being totally honest.

Nice work, i have been checking on this capacitor as well. Instead of
replacing the batter, i hope to use the capacitor as side-by-side for the
current acid battery. Still got space to fit them in. Cause i am tired
changing car batter every 6-9 months cause of dead batter. Can you test on
this for me or share on your next video? thanks first.

A standard lithium cobolt jumper pack can start the car. its a quick
discharge & resonably small .but the capacitors cant run your light horn or
radio. if it was this easy.... highly qualified Engineers that design cars
would be using capacitors 😑 wouldn't they! instead of a back yard hack

10:30 If these super-capacitors only hold charge for a few days then they
can hardly be called capacitors at all!
Maybe they should be described as virtual batteries or superchargers.

Circa 1980 I had a motorbike (Norton Commando) which was kick start and had
an alternator. I had a dead battery and found that replacing it with a
capacitor (probably 4700uF 50v at the time) allowed it to run perfectly
well. It obviously wouldn't work with an electric start machine and I
wouldn't trust it with a computer based system on a modern bike, but this
was old school technology and was e-bomb proof.

Sounds like a great way to kill an alternator.

If this works so great, then why didn't Toyota go with capacitors instead
of nickel batteries for their hybrid? Oh yeah, because this doesn't
actually work. At all.

My research and math says that 300 farads is about 9mah. ... That's not
even 1 amp. Car batteries are generally 75 amps.

Автор William Maynard ( назад)
that voltage meter and cap pack combo would also work great to find power
draining issues, the cap will drain much quicker than batteries and charge
right back up so you could isolate the issue easier

these caps wouldnt be able to start my 12v cummins diesel in cold

Автор chris howarth ( назад)
Hoax, the voltage would decrease dramatically even for a small current flow
because the voltage decreases exponentially across capacitors when they
discharge. The fact you started the car as well, requiring 100s of amps to
start, and your voltage is still the same as you showed on your cigarette
lighter proves to me this is no doubt a hoax.

Автор Mike Hunt ( назад)
He does not have 2,300F with 6 of them in Series.. Having 6 of them in
Series on that bigger pack lowers it to around 380F without the tolerances
included.. Someone needs to learn how Capacitors work, Also it is dangerous
to put that many high end caps in Series without some kind of charging
circuit to make sure they do not charge uneven. a simple led resistive
circuit would work fine..

I've been using a bank made from 12x 350F capacitors (same as 2x small
packs in parallel) with a 12v 10 Ah lithium battery in parallel to keep it
from dying. It's in a 2002 Mustang GT with a 4.6L. I'm looking into adding
a small hold up solar panel so the devices would last indefinitely as well
as some circuits to isolate the battery from the alt and cranking. I'm
satisfied with it so far, dropped 30 lbs from the front end of my vehicle.

Автор ScorpionRegent ( назад)
A car battery's main job is starting the car, but one of the things it also
does is stabilize the voltage to help guard the computer against voltage
spikes. If capacitors don't do that you could be putting your computer at
risk if you start running without a battery. It might be a better idea to
use the capacitors as a jump starter and a reserve power source.
