This is interesting.
What is your take on this concept?
Here is what Polar Power has to say on the subject.
Super-Caps can deliver more cranking amps than any automotive battery and in any weather. We suggest using super-caps in extreme weather installations, helicopter and remote access sites, and where battery theft is a problem. Super caps have a long life of between 15 to 20 years and up to 1/2 million start cycles. The long service life helps eliminate the problem of maintenance crews installing cheap batteries of poor starting reliability. Super caps have plenty of energy to operate glow plugs and crank diesel generators in temperatures as cold as -50°C or as hot as +65°C with multiple cranking attempts. Excellent for LPG/Propane generators too.
Be even better in a hybrid, when you want to jump on the pedal to get moving quickly without having to kick in the gas engine.Super Caps are a good choice in electric cars to supplement the main battery.
They provide lots of power at take-off, charge fast in the coasting mode & regenerative braking, weigh very little, stay charged a long time.
Not necessarily. What would the battery industry have to say about it? recyclers? Still using 1950's technology on wet batteries.The car manufacturers would have implemented this decades ago if it were truly viable.
Since caps are additive in parallel, It should be feasible to manufacture something like this in the future.Actually capacitors of that size !
Will hold a substancial charge,
And for more than a few seconds !
I once made the mistake of shorting out a 10F gold cap bank !
To say the fireworks where impressive would be understating it !
completely vaporized all the copper tracks in an instant !
So the charge from 350F would be enormous !
Dont under estimate it !
And no F is not a typo ! I mean FARADS not MICRO FARADS !
I'll give it a stab:
A 500CCA battery that was run for 10 seconds would put out 60k joules.
That capacitor will supply 1.09k joules, so it wouldn't provide nearly the same cranking time.
If he had a 12V 833F capacitor, he could get 60kJ.
