How much money would a capacitor-based car battery save you?

An often-quoted number is that hauling 100lbs around in your car adds 1% to
fuel consumption. If you remove a 30lb battery then you save 0.3% of your
fuel bill. If you are spending $50 per week on fuel (the average for
Australian drivers), this adds up to $2600 per year. 0.3% of $2600 is
$7.80 per year in reduced weight leading to better fuel economy.

Capacitors can be recharged hundreds of thousands (to millions) of times,
unlike lead-acid car batteries which will be dead after one (or two)
thousand cycles (at the most). If you replace your lead-acid car battery
every 4 years, you would have to change the equivalent capacitor-based car
battery every 400–4,000 years. So, in effect, you would never need to
replace it (nor would your children, or their children, or their
children...). Since a car battery might cost you about $100 every four
years, you are spending $25 per year on lead-acid car batteries.

A capacitor-based car battery would thus save you $25 + $7.80 = $32.80 (on
lead-acid battery replacement costs and in improved fuel economy) each and
every year.

Over the course of a 50-year driving career (20–70), you will have saved 50
* 32.80 = $1,640. If, on each anniversary of installing the
capacitor-based battery, you added the $32.80 you just saved in the
previous year into a bank account earning 5% interest, when you retire from
driving you would have about $6,900 sitting in the account. Give the
battery (and the account) to a grand-child and get them to do the same, and
they would retire from driving with $85,600 in the bank. If your
grand-child does the same thing, then your great-great grand-child will
retire from driving, with the exact same battery, 150 years after after you
built it, with $989,000 in the bank... Great-great grand-dad sure was a
smart fella.

Moving away from lead-acid batteries makes sound financial sense, provided
you think ahead far enough.

Do they store enough current to restart the engine after the systems such
as clock and radio memory and alarm / imobiliser have drained a little
overnight. Also for how long can they hold a good charge. I have experience
of small electrolytic capacitors and they dont hold charge for more than a
few hours. I would be interested in substituting my leisure batteries for
some super capacitors if it would work well enough.

Автор DJ Dragon (2 месяца)
Has anyone actually done the math to replace a battery with super
capacitors? For the record it would take a super capacitor bank of (let's
use the maxwell 3,400 farad 2.85v at around $70 each) 43 super capacitors
totaling over 146,000 farads to equal a small 12v 40 amp hour battery.
(Most of today's cars use between 60ah and 80ah battery so basically double
my example) That's about 9 parallel circuits of 5 supercaps in series.
That's a lot of money. That's not even counting the extra circuitry needed
for proper charging, discharging, and voltage stabilization. Sure in the
old days when a car only had a starter and and ignition coil and some
lights this would be useful but not in today's cars. Cap banks are good for
jump starting a car with a dead battery. I have one from Snap-On that fits
in my pocket.

I was looking at this video, because I wondered if I could use a super
capacitor bank with a Goal Zero Yeti 400 watt power pack. On the Goal
Zero site, it says you can not jump start a car with their Yeti power
packs, but with a Super Capacitor, I think I could jump start a car, that
has a dead battery. Also a Super Capacitor could help with surge current,
that could kill a Goal Zero Yeti power pack without the capacitors. If I
am out at a camp site with a dead car battery, it would be cool to get out
the Yeti 400, that was charged up on solar, then with the Super capacitor
connected between the Yeti 400, and the car, it should start up.

Capacitors are great for producing good cranking amps. They're not quite so
good if you need a little more - like the thing doesn't want to start and
needs 20 ~ 30 seconds of cranking over. As long as the engine fires up
straight away, it's great. Don't listen to the radio for an hour and then
expect it to start though... Make sure the switch for the light in the boot
works... and I have some doubts about how long it will stay charged for.
Old style batteries can also go flat over time, but I have a feeling it's a
bit worse with capacitors. His sat for a weekend, but those capacitors are
brand new, and I would hope he made sure there was no electrical drain
while it was switched off. Many cars do have at least one thing on all the
time which draws current, some have several. Many modern radio / music
player things will need a PIN to restart after all current is removed -
they think they've been stolen. But keeping them powered up takes current.
What about a car alarm?

In other news today, a couple of guys at Stamford University have
discovered how to make an aluminium battery, which doesn't quite give the
same voltage / energy density as a Li Ion battery, but it's in the
ballpark. In every other way, including cost of manufacture, weight /
density, safety, it's massively better. It is flexible, and unlike a Li Ion
battery, it can't burn if there's an internal short. And it can be
recharged very quickly.

Ultracapacitors (which are also more expensive per energy unit than
batteries), can store only about 5 percent of the energy of comparable
lithium-ion batteries.

when the engine runs, the battery acts as a damper and a reference for the
alternator regulator.
If you disconnect the battery when the alternator is charging, the
regulator sends full current to the alternator field coil and the
alternator delivers as much voltage than it is dynamically possible well
over 14 volts and every component not bulletproof will fry
it is a cheap insurance to keep a good battery in the charging circuit

Maybe sound good, the less weight, and some starts in cold weather. But,
the reality is, the charge is too short than regular car batt., you now,
the car need to supply the current no have in the capacitor pack, mean,
less current retention than regular batt, = MORE FUEL SPEND to run the
alternator. When the accessories consume manies ampers, the current in the
batt., give the necessary supply to the proper function in the car & the
alternator don't work hard to supply ampers to the batt. to charge it; the
cap. bank, supply the ampers, but DO NOT hold to much charge in the bank to
give the opportunity the alternator to charge in low demand, because the
accessories of the car DEMAND to much current. Cap. bank = more fuel

Replacing My Car Battery with Capacitors! 12V Boo…:

Автор TheLuismondo (6 месяцев)
Capacitors in series divide the value of 1 of them by the number of
capacitors (if they are the same value)
Capacitors in parallel multiply the value of 1 of them by the number of
capacitors (if they are the same value)
So if each one of them is 350Fs and you have 6, you can either have 2100Fs
in paralel (you need them to be rated at more than 16 volts) or 58.3Fs in

Low end lead-acid car battery
= 12V x 24 Amp Hours.
= 0.15 cubic foot
= 18 lbs
= $65

Lead acid cannot be discharged below 1/3 (33.3%) without damaging battery.
Therefore effective amp hour ~= 16 Amp Hour @ 12V.

Compared with
12 V x 1 amp hour
= 5 x 2.4V (overvoltaged at 2.7V) x 3600 amp seconds
= 5 x 3600 x {1 Farad 2.7V boostcaps}
= 36 x { 500 F 2.7V boostcaps}

That is presuming we overcome the series capacitance being reduced by using
a regulator/switching circuit.

12V @ 16 Amp hour
= 36 x 16 x { 500 F 2.7V boostcaps}
= 576 { 500 F 2.7V boostcaps}
= 576 x 0.0028 cubic ft + spacing allowances ~= 576 x 0.003
~= 1.73 cubic ft
= 576 x 0.15 lbs
= 5.4 lbs + 2 lbs of harnessing frame + 1 lb of charging/discharging
regulator / switcher
= 8.4 lbs
= 576 x $15
= $864 + $50? homemade regulator / switcher + $?? homemade frame.

Without the regulator / switcher, you would have to multiply the number of
boostcaps by 5, which would make your supercapacitor battery-replacement
array heavier than the battery being replaced. Not to mention the size.

The regulator would be a 2.4 V - 12V step-up / step-down charge /
discharge. Efficiency of regulator = 90% ? at most ?? So you have to add
10%, 15% more boostcaps to compensate.

The alternative without the efficiency loss is an intelligent
parallel/series charge/discharge switching circuit.

Also, you SHOULD NOT charge boostcaps in series without a balancing circuit
across them, to ensure their 2.7V individual threshold is not violated. The
balancing circuit will cost you either efficiency (passive cct) or extra
money (active circuit).

You seem to be oblivious, not only to the reduction in capacitance but also
to the damage you are risking in charging the supercaps, when placed in

Hours of happiness constructing an expensive over-sized battery replacement
= priceless.
Damage due to charging boostcaps in series = ???

Now compare with $350, 150 Amp Hour, 100 lb, 0.75 cubic ft high end

UPDATE Please, after you test and how long is this capacitor pack tested?
is it safe to put in the car now? I have a Honda Odyssey 2002. Is it safe
to put this in the car without damage to the electronic mother board etc..
? the cap to to 16.2 volt. while car battery only 12.5 volt right? is the
high voltage damage car electronic ? ( I have to get new battery every 3-4
years max on this Minivan which I want to buy capacitor but worry about it
damage my car electronic. thanks a lot guys. Professional please email me:
mcviethieu at yahoo. thanks again a million.
I saw ebay people sell circuit board for protection to the capacitor? do I
even need it? because capacitor not go over 14.5 volt right, from the
alternator? and the Capacitor x6 = 16 volt?
