Solid State Bedini

[Jetijs]

Hi Mart. It's a great setup you have there
I would go up in amperage for those 200Ah batteries. I could charge my 200Ah battery to the max in about 20 hours with 5.2A input at 13V. You have to adjust the base resistance so that each transistor handles about 0.5-0.7A, that should handle the heat. My transistors are just slightly warm, of course they are glued to a small aluminum plate, that also acts as a heatsink a bit, but I am sure, that they should work the same also without the plates.
Mart, where did you get the CBA2 new software? From their web page? Is it for free or does it cost something? And can this new software be used with the olds CBA tester?
Thank you,
Jetijs
BTW, my 60Ah battery has now improved to 18Ah

Hi guys, heres something Ive been working on for a few weeks now. Inspired by John Bedini and Erf. Its an extension of the capacitive discharge pulser in solid state form. I still have some tinkering to do with it, and it may not need all the transistors, as the caps are all connected on the positive leg, so they all charge.

Basically it is SCD, sequential capacitive discharge. I wanted to see if multiple capacitors could be used on the backend, with each one firing in sequence. This would hopefully allow for each cap to build up a higher potential without the battery having to wait for extended lengths inbetween.

So far it seems to work good. I modified a simple LED chaser circuit so that the LEDs will trigger the opto isolators. Their timing is also adjustable via pot.

I have five transistors for a 6 filar coil, I think that I may only need one however. Each transistor is connected to a bridge, which feeds 5 120uF 330v photo flash caps.

Just waiting on the SCRs and optos to fire it up. I think it could be utilised or modified for other purposes, for example replacing the charging battery with another coil or a spark plug. Anyway, heres a pic.

Thank you Jetijs,

Then new software is here...

West Mountain Radio - Computerized Battery Analyzer Software Update

Congrates on the extra amp hours out of your battery.

Hi Mart
Just tested the new software. Works great. Although still I like to discharge my batteries with the previous software version, the new version has its advantages. I like the charging monitor the most. Although it is said in the manual, that you shouldn't use a charger that has the same ground as your computer and also the radiant spikes are not the most electronic friendly stuff, I still took the risk and monitored the charging of my solid state charger. Worked good. Here is the charging curve:



We can see that at about 550 minutes of charging, we got the highest voltage, that stays the same for a while and then gradualy starts to drop dwon, I think that this is because battery heating up, because as the battery charges, there is no heat, but when it is fully charged and the charging is continued, heat starts to appear. I guess that those 550 minutes is the optimal charge time for this battery.
It is great that we have such a charge monitoring tool.
Thanks,
Jetijs

I have a usb multimeter but the software that comes with it is c##p... do you know if this software will work with any meter or is it just for one?

Sorry man this is only for the CBA .....

I had trouble this morning with mine, I tried 10 amps pull on the batteries and it reported that it was overheating Think I will create my own 10 amp load with my crock pot and then use the charging feature to measure voltage.

[Jetijs]

Seph, I don't think that this software will work on your multimeter. It is specially designed for the CBA battery analyzer.
Mart, that is a big load. I have never tried a load this big. The biggest I tried was 7A

I called CBA asking them why the unit may of shut off...

The answer was I charged the battery up to 14.06 V... and I was pulling 10 amps thus...

140.6 Watts is what I was pulling on way over the capacity of the measuring of the device. Makes alot of sense now.

Stronger testing of the Golf cart batteries.

Decided to really push them...

Pulled 14 amps for 286 min ( 4.76 hours ) so I got 66.73 amp hours out

Is anyone here getting > 1.0 cop out of their bedini chargers? My understanding is that the batteries when conditioned overtime will give more amp hours than was put into them. It seems like everyone here is aiming for a fast charging rate but what about the cop?

I'm confused as to what to expect from bedini technology. I see a lot of experimentation and variations on johns circuits but no mention of cop results. Has anyone been able to run the machine off conditioned batteries exclusively without external input, like using a conditioned charge battery to run an inverter to charge the primary closing the loop?

Also another question I have regarding scaling up I've read it can get expensive but I'm wondering if someone can give me a better idea. Where's the expense come from and how much are we talking about?

Here's what I have in mind in terms of cost for a modest but hopefully practical system, correct me if I'm wrong. I could be way off here. This is just off the top of my head..

Off Ricks site he's got 10 MJL21194 transistors for $55, 1 ten pound spool of magnet wire for about $100. I think there's 1000 feet of wire on those 10 lb spools but I could be wrong. So let's say I can build 2 coils of 4 strands each at 120 feet, 4 transistors per coil, and say 6 coils. That's $300 for magnet wire for the coils, let's say $150 for transistors, and maybe another $100 for diodes and resistors, total is about $500 to $600, lets say the rotor is made from wood and the batteries are surplus so maybe total we're looking at $1000.

I thought I read somewhere that John's big 10 coil machine cost like $30,000 to build, I'm assuming that is including R&D costs to get to that point, or am I missing something?

What really got me into this Bedini thing was energy from the vacuum #2 where John showed his big 10 coil machine and the other machines with high cop and he said we show people how to do this on the yahoo group. Since then I've been reading and reading on forums and posts on the group but it seems like he's given just a very basic starting point and its not at all easy to replicate his cop performance specially for a person with little to no experience in electronics such as myself.

I guess what I'm looking for here is either encouragement or a reality check.

Hi Mate,

The machines themselves are not COP>1, the batteries are where the extra energy is to be found. I have been able to get more out of my batteries that it took to charge them, sometimes up to 2 times the amount. (Not capacity, just energy out compared to conventional energy in) I am sure others have too. If I can, anyone can.

As far as the expense goes, I have almost completed a 20 circuit charger and so far it has cost me about AUD$750. By the time it is complete it will be just over AUD$1000. That is just for the charger, not the batteries. Most of the expense is in my coils. I couldn't be bothered winding them myself so I get them done by a professional. They are five strands each and cost AUD$150. I have four of them on this charger. The rest is cheap as. I ordered my 20 transistors (MJL21194) from the states before the dollar went to crap for AUD$6 each (and I've only blown 5 of them )

I think the majority of JB's costs were his batteries. Would have been hard to find 24 surplus batteries in good nic. I'm sure some would have been got at full price.

Cheers,

Steve.

Fast Charging

@Jetijs,

I'll like to thank you for your sharing circuit ... work well for me and charging very fast..., I use 2 tri-filla coil and draw 2.5Amp
Bit hot at the coil and resistor.... I used little fan to help as cooler...
I have check with my old oscilloscope showing the "h" waveform like yours.
Sorry I can't attach the picture right now ... "camera problem"

Hello
Could you try this with your circuit and see if it helps any.
Unhook one of your transistors so you have an empty winding on your coil.

Then run your BEMF back thru your coil going in the positive and then comming back out the negative.

Heres a video showing what I'm talking about.
It incressed my voltage from about 16v to to about 150v after going back thru my coil.

Ok,

Can you take a standard Bedini schematic and show us where you are moving the wires around to?

Thanks for sharing, does it increase the charge rate?

@ Theremart

I dont have a coil wound for the Bedini circuit.
I was woundering if it would work the same as the setup I have.

The setup I'm using now is the same as in the pulse generator thread.
But it should work the same.

If you have a coil with more than one winding.
Send your BEMF thru the positive of your second coil winding(it should be the start of your coil)then it just comes back out the negative side of your coil(the end of your coil)

Lidmotor allso made a Very Nice video of it on youtube.

YouTube - Slayer007 Back Energy Booster---My replication

There is a circuit of it in the pulse generator thread its a little differant setup than the Bedini but it should work the same.

Here is another video sowing the differance in voltage and amp draw after a load.
The load was a 110v nightlight.
The amps shown in the video is the current going to the light.
Then after going thru the coil it show more current and voltage going to the light.
