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.

lets put a flamable sock over these capacitors to make them hotter than
they need to be....why? 😐 because he's an idiot!

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
like this guy.....

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.

Nice but wouldn't they get hot & explode?

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.

Hi, It's just wonderful to see useful R & D effort from your-side. Did you
also make the car a Hybrid-one by adding the LI-Ion battery ? How are the
results ? How much it would cost to turn my Honda Civic 2011 to be a
Hybrid, in your suggested approach. I appreciate your inputs and would like
to participate in your research efforts.

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.

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..

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.

Yeah this is no good, capacitors discharge completely the instant the
circuit is closed, and after that, unless they are recharged by the
alternator, they're useless... The only way this would be practical is if
there were a method for regulating the discharge, and to my knowledge
nobody has figured out a way to do that yet.

Rather than a capacitor. How about a lead battery desulphator. Instead of
getting 5 years out of a battery I think you could get 8 or more years. I
am using mine for it's second year. I have learned you cannot do anything
with a swelled (frozen) battery but sometimes I am able to save a battery
that will no longer start a car. I have stopped fooling with the really bad
ones and am doing all my batteries every 2 years. This seems to keep them
clean and more powerful. I desulphate mine for 3 weeks.

Автор Robert Applegate ( назад)
Besides being the source of the energy to start the engine, the battery is
the stabilizing element that insures that the system voltage stays in a
reasonable range. In addition, the battery is effectively the same as the
capacitors in that it provides pretty good filtering of the electrical
noise. Taking is out of the system in a car full of high tech 12 DC
electronics is not smart. Remember, stupidity is nearly always expensive!

Автор Devin Williams ( назад)
Lead battery is already obsolete in every aspect except cost basically.
Comparing to that type of battery is a stupid way to see if capacitors make
batteries obsolete

Автор Zyle ( назад)
Super capacitors have been around for a long time, they are not new. This
is not new technology, and there is a very good reason why they are not
used in place of a standard battery. Mainly the overall capacity, not the
voltage. Sure you can get enough voltage to kick the startermotor around,
and enough current. But the battery does a lot more than just provide power
to the starter motor.

Yes you can start a car with capacitors, you can start a truck with a
lithium battery pack from a drill.. does not make it a viable long term

Автор Markus Haefner ( назад)
Do you think parallel connection of supercaps and car battery is possible
without any troubles ? .. This could give you both advantages

Автор Michael Beeny ( назад)
Might be interesting to find out what the stand by current is when the
engine is off. This will decide how long you can not use the car between
start ups. Even a 50mA drain will soon drain the cells. One great advantage
of capacitors over battery's is that they will re charge after only a few
seconds, where a battery will need 20 minuets or so.

Автор Pepe Perro ( назад)
Capacitor discharges after 24hrs of sitting if not sooner. In cold climate
this would not work. If this Scion motor is already warmed up of coarse it
takes very little effort to start. You can also start the car with 36
pieces of AA batteries connected in 12V series and then parallel to
increase the amperage. It works better than this capacitor start with a lot
less cash to assemble

but went online and said on there Peugeot will not start on 11v so bought

Ffs people, it did start the car, those capacitors can deliver a lot more
than 12v, the car will draw what it needs, so those capacitors are only
delivering a fraction of what they can actually put out, if they discharged
instantly they could kill you

Автор turboslag ( назад)
Ok, this demo doesn't really surprise me, all that is needed is to look at
the science behind it. They are 350 farad caps, but in series the
capacitance is divided by the number of caps, so total capacitance is 58
farads. Charge on the caps at 14 volts is approx 5700 joules. 1 joule = 1
amp, through 1 ohm for one second, so this pack can deliver 5700 amps,
through 1 ohm for 1 second. Starting current for that vehicle would be
about 150 amps, so that means a starter motor resistance of about 0.1 ohms.
So this pack should theoretically deliver 570 amps for 1 second through the
0.1 ohm starter motor load, which should equate to about 4 starts, without
any recharge.
So, a test to determine the number of starts possible without the
alternator connected should prove the theory.

BU-209: How does a Supercapacitor Work?

Discover how the supercapacitor can enhance the battery.

The supercapacitor, also known as ultracapacitor or double-layer capacitor,
differs from a regular capacitor in that it has very high capacitance. A
capacitor stores energy by means of a static charge as opposed to an
electrochemical reaction. Applying a voltage differential on the positive
and negative plates charges the capacitor. This is similar to the buildup
of electrical charge when walking on a carpet. Touching an object releases
the energy through the finger.

There are three types of capacitors and the most basic is the electrostatic
capacitor with a dry separator. This original capacitor has very low
capacitance and is used to filter signals and tune radio frequencies. The
size ranges from a few pico-farads (pf) to low microfarad (μF).

The electrolytic capacitor provides more farads and these larger units are
used for filtering, buffering and signal coupling. Rated in microfarads
(μF), this capacitor has several thousand times the storage capacity of the
electrostatic capacitor and uses a moist separator. The third type is the
supercapacitor, rated in farads, which is thousands of times higher than
the electrolytic capacitor. The supercapacitor is used for energy storage
undergoing frequent charge and discharge cycles at high current and short

Farad is a unit of capacitance named after the English physicist Michael
Faraday. One farad stores one coulomb of electrical charge when applying
one volt. One microfarad is one million times smaller than a farad, and one
pico-farad is again one million times smaller than the microfarad.

Engineers at General Electric first experimented with an early version of
supercapacitor in 1957, but there were no known commercial applications. In
1966, Standard Oil rediscovered the effect of the double-layer capacitor,
which makes the supercapacitor work, by accident while working on
experimental fuel cell designs. The company did not commercialize the
invention but licensed it to NEC, which in 1978 marketed the technology as
“supercapacitor” for computer memory backup. It was not until the 1990s
that advances in materials and manufacturing methods led to improved
performance and lower cost.

The supercapacitor has evolved and crosses into battery technology by using
special electrodes and electrolyte. While the basic Electrochemical Double
Layer Capacitor (EDLC) depends on electrostatic action, the Asymmetric
Electrochemical Double Layer Capacitor (AEDLC) uses battery-like electrodes
to gain higher energy density, but this is affected by a shorter cycle life
and other burdens shared with the battery. Graphene electrodes promise
improvements with supercapacitors and batteries but such development is 15
years away.

Several types of electrodes have been tried and most are based on the
electrochemical double-layer capacitor concept, which is carbon-based, has
an organic electrolyte that is easy to manufacture and is the most common
system in use today.

All capacitors have voltage limits. While the electrostatic capacitor can
be made to withstand high volts, the supercapacitor is confined to
2.5–2.7V. Voltages of 2.8V and higher are possible but they reduce the
service life. To get higher voltages, several supercapacitors are connected
in series. Serial connection reduces the total capacitance and increases
the internal resistance. Strings of more than three capacitors require
voltage balancing to prevent any cell from going into over-voltage.
Lithium-ion batteries share a similar protection circuit.

Автор jay kallionosio ( назад)
This is too cool

Автор Frank Magowan ( назад)
That's a neat trick, but the cost + more frequent replacement would
probably add up to more than a battery would have over a 2 year period
(maybe less)
