RE-EMF Charger

[SkyWatcher]

Hi folks, I am having some good results from this charging circuit.
I added a 12 volt-1.5 farad car audio capacitor across the charge battery.
I will post the exact circuit i am using sometime today.
I have run many tests and have just made two consistent tests, showing efficiency above 100%.
I am using one 12 volt tractor battery, 235cca as charge battery, as my bank of 3 in parallel, takes too long for testing.
I use a cen-tech inverter with led bulb connected as a discharge load.
Then measure amperage with a 1 ohm resistor at start and end of predetermined discharge, which is based on observing previous voltage of battery under discharge, when it blips to a certain voltage value, then test is done.
Input is 19.45 volts, from a laptop power supply and average amperage is determined by again using 1 ohm resistor to check at beginning of charge run and end of charge, voltage stays the same with this psu.
The input for both tests is 5.7 watt hours, charger is run for exactly one hour.
Test 1:
Input = 5.7 wh
Output = 8.6 wh
Efficiency = 151%
Test 2:
Input = 5.7 wh
Output = 8.9 wh
Efficiency = 156%
All questions, replies, comments much appreciated.

Edit: one more thing, be sure to allow the capacitor to keep charging the battery, even when power source is disconnected, because at least with my capacitor, there is a lot of juice left to help charge battery.

Good job Sky!

Hi wistiti, thanks.
Here is the circuit and a few pics of setup.

Hi Sky, well done. it is a pity that I have packed my electronic workshop in connection with relocation, else I like to make a replication (on small scale) to check the claim of 150% efficiency.

[ewizard]

Just a quick ? What is the number of the high speed diode?

[SkyWatcher]

Hi bertoa, thanks very much, well when you do, let me know, i'll answer questions or help.
Hi ewizard, the high speed diode, is a FUR460, 420-600 volts, 4A-50Amax, 50ns RRtime.

Hi Sky.
You can try with a serie of led before the resistor (like the pic) you can use any color. the idea is to be near the supply voltage...

I have not calculate the p in vs p out but it may be interesting...

Ciao!

[SkyWatcher]

Hi wistiti, thanks.
Yes i've seen that add-on and i thought i tried it before, though i will try it with this setup i have now and see if it gives even better efficiency.
Have you tried it with the capacitor add-on i posted, it is in my opinion, what is giving the 150% or so, efficiency figures.
The idea is that the capacitor will more efficiently collect the spikes and then the capacitor can transfer the energy slower and with more real current, that the batteries like.
Though for desulfating, a switch could be added to bypass the capacitor.
Also, if one wishes to split the positives, a PNP transistor can be used, as i know matt mentioned that potential problem with work done between the negatives.

Hi Sky.
No i have not try your setup (with the added cap) yet but i will soon. i have some photo flash capacitor in stock...

Did you mean replace the npn transistor with a pnp??

thank you!

[SkyWatcher]

Hi wistiti, you can use an NPN transistor, i was only mentioning matt jones comment, where he claims splitting the negatives could cause issues with some batteries.
I would use NPN first, as that is what i used for the results i have.
I hooked up 2 blue leds in series with base resistor, it cut in half the current draw.
Though i notice it lowered the output also, charging is slower.
Question is, is it more efficient with the leds on the base.

Edit: i forgot about the recommendation in patrick kellys book, to add more leds on base circuit, until it needs to be manually jump started and then extra efficiency may be had.
So i will be playing with those tweaks.

Hi folks, Hi wistiti, i have been testing the led base modification this morning.
I'm using 4 leds in series, 2 blue and 2 yellow or gold.
With 5 leds in series, the voltage on charge battery bank starts to go down, though with 4 leds in series, it climbs at a decent pace.
Of course, the circuit has to be jump started.
With the 4 leds in series on base, with the 500 ohm resistor, the circuit is drawing 1.26 watts, into a 90 amp hour-12 volt battery bank.
Sometime today, i will switch to using only one 12 volt tractor battery for testing, to shorten the testing time and we will see if this base led modification has made the system more efficient.
Just the fact that it is charging up a 90 amp hour battery on only 1.26 watts, at a steady pace, that alone is promising.

Hi all, Hi wistiti, the efficiency when using leds on the base, results were not as good for my setup, 94% and 114%.
I am re-testing the original setup, to make sure of results again.
Then i am going to try it without the capacitor.
Then i will try with two, 1.5 farad capacitors in parallel, to lower even further, the impedance of spike collecting capacitors.
Since, i am aware that the radiant spikes like lower impedance, for better accumulation.

Hi all, i think i am mistaken about the 150% efficiency.
Somehow, my battery was plateauing at one spot and after i changed my discharge load to a couple yard bulbs in parallel, it revealed that voltage spot of battery hanging for a bit and not reflecting a true discharge of inputted energy.
At least that's what it seems like, unless i find something that proves that wrong.
I can say for sure, the capacitor increases the charge efficiency of this circuit.
Sorry for jumping the gun.

Thanks Sky
It becomes clear very quickly just how fast a battery will
go south. Keep up the good results by establishing the norm.
I am doing the same thing right now. For instance you mentioned
spikes and spike make my caps like new again. Some caps are
self healing and other caps run on heavy current bleed like stuck
pig. I always spend time conditioning both cap AND battery.

I am doing it now starting last night my batteries got this....

1) Spike mode on the Bedini SG OSC this is a solid state pulse
circuit that will reverse battery stagnation.

2) Battery discharging and forming using DC power then Bedini
Generator Mode with the warm pulses.

3) Long slow charge floating up easily to 16vdc

Once this has been accomplished (and I don't mean maybe) you
will have spent considerable time and process doing it in days
not minutes.

I can't stress enough that a battery or a cap must be properly
conditioned and cared for as these storage vessels become many
bad things if left uncared for. High resistance and irregular charging
and discharging curves will ensue. Lets face it most batteries are
in poor standing because very few do this to their batteries.

You will never know what to expect from one cycle to the next.

Good to see someone looking at the actual numbers and reporting
even when it sounds like a failure. If at first we don't succeed?

I know that Re-EMF circuit will give a slightly higher recovery result
over circuits that just pulse but I have always thought that RENE
had speed of charging in mind. It charges fast he says.

Of course the reasons for fast charging will sometimes be because
the BATTERY being charged has always been charged another way
and the new circuit with the spike will sometimes cause a diminished
battery to come alive quickly.

That is not to say that the charging rates such as C10 C5 can be
ignored once batteries have been revived or recovered from cold
storage.

Again the pulse ON TOP of a spike might be far better for a great many
batteries that were only use to raw dc OR pulsing circuits using 12vdc
to charge a 12vdc battery. The extra push in RENE'S circuit comes from
both pulsating current (Bang a spike) and higher voltages than other
designs had offered in the past such as the SSG in the beginning was
all spikes.

I ran and ran and ran spike mode and some of these batteries would
not go up after hours. Just wasted power. Then John Bedini came out
with the generator Mode and this solved all my problems on the spot.

I was there when John came out with Generator Mode and it was at a
time that I just happened to be building his early circuits.

Yes the Rene circuit will no doubt be great to charge batteries.

Keep after the data and I will also. Graphs coming.
