3 Battery Generating System

Never said that

Post# 4047 clearly said MATT is lying, but has since been changed.

Everyone can view that post and see there is no edit. I could not have altered it without an edit being recorded and displayed. Here is a copy of the post where I say that you are incorrect, which is distinctly different than saying you are lying.

Hello Altrez,

PWM motor controllers are buck converters and operate efficiently employing current multiplication through a freewheeling diode. Matt is incorrect. They do not waste 50% of the power at half voltage. Please don't believe me and look up buck converter or PWM DC motor controller.

Regards,

bi

BTW, where might I buy one these PWM motor controllers which are not buck converters? I've been working with DC motor controllers since before they started using mosfets. I've never seen a PWM motor controller without a FWD.

To All, Norm and Bi

That's the second time I try the 2 batteries setup, this time under load, after Dave's advise. My batts are fairly new one year old, 74Ah each and so I have 2 parellel on each side.
I used the small boost converter but in less than a minute I burned it. Then I used a 400watt one which was volt and current adjustable. I confess that being afraid of burning this convert as well, I didn't open completely the current. Also trying to be on safe I put small load also on the generator attached to motor, counted it and was 10watts. So I didn't follow the advice of David to the fullest.
The motor had to use around 35 watts to keep the 10 watts on the gen. Run it for two hours. 20 min on, 40 mins off, few rounds totally 2 hours. Then left them to rest. After 30 hours the two group of batteries where all higher. 41 hours later both are still higher than started. One is 0,02 volt and the other is 0,05 volt. Totally, I used like 70wh and still all 4 batts show gains. I wonder how much better could it be if I had not limited the current, if i have used deep cycle batts instead of car batteries and the modified motor would not get that hot.
I think also the effect is improving by the long intervals in between runs.
Relatively small loads but still clearly shows the potential. Doesn't it?

Reality

liber63,
Once you have built it and seen it working on your own bench, it becomes more difficult for people to convince you that this doesn’t work. The proof is not in how much voltage or current moved from here to there. The proof is in the batteries. As you run this you will see increased capacitance in the batteries, and that they do not lose their charge. How is that possible when you were running loads the whole time if there is “Nothing to this”

Now you know it works. Don’t let anyone tell you it doesn’t just because they believe they are experts. Go slow and keep good records. I found that a battery analyzer is a pretty important tool to give me good data as I experiment with different circuits. At times I found my voltage might go down .01 volts during a run but the analyzer showed the capacity of the battery had gone UP, meaning, when you do the math, that it would actually hold MORE power. Resting helps these changes take place.

See just by taking the time to look you have found something. These things happen and there is no explanation why. Its just proof that running these collection systems yields gains.
Your equipment is quality too, big batteries, big wires everything thats needed to make it work.
The only advice is no matter the explanation thrown at you keep your eye on the ball and keep your mind open, keep looking. Don't discount anything.
If you find an effect and you can modify to make it better then your on your way.
I am really happy for you. I know how good it feels to watch stuff like this happen. Contrary to what the "Facts" say.

Yes, it's really very exciting. I knew the truth of that by reason, having done similar experiments but not with the right stuff. Now I see it with my own eyes. Nobody can take that from me.
One more thing, I was wondering if all this experiment would do better if the voltages for all was higher, say 24volt for the batteries and 40 for the boost or even 36 for batts and 52 for the boost. I think it's been said here before. Of course, there is no need for that really. Maybe it becomes more complicated.
With my previous setup, I had the batts before start around 12.80 and the boost at 29,2volts, if anybody is wondering.

Higher voltage

One of the biggest losses in the system you have to make up for is the boost modules, and they are MORE efficient at higher voltages. But high voltage DC is deadly, so there is always that risk when you get TOO carried away. And we were trying to show an inexpensive system that WORKS and proves what we have been saying. I’m not going to talk about something I have not run myself. Matt has done way more work running on potentials than I have, so maybe he will comment. All my time has been devoted to the generator side.

Ya the problem is the boost converter start draw too much current at higher voltage and then exceed themselves pretty easy. I've burned a crowd of them up, I know.
Thats one thing I want look at building specifically for this experiment, so we can get plenty of current without worrying about exceeding the parameters of the converter.

I'm pretty sure Matt knows of much better tutorials.

[altrez]

I was wondering is someone could please post the most current schematic of the 3bs with boost converters?

Thanks!!

Hi Altrez
Here is the basic one.

Hi Altrez
Here is the basic one.

Thank you! What voltages are the boost converts set at?

Latest Circuit

Post #3931

This is the circuit we have been talking about for a couple weeks now at least. But it only requires ONE battery. If you HAVE more batteries than that, just put them all in parallel. If you don’t remember what we said about the wires when using parallel batteries, you have some reading to do.

I understand now. The parallel battery's were confusing me.

Thanks!

Just a little progress. Hopefully running by Sunday. Start the tuning process.
