Solid State Bedini

Slightly OT

Is there a timer/switch circuit that will allow me to automate, charging/conditioning with discharging? So that when a battery is at max charge a sensor will trip relay attached to a resistor that will discharge it at c20 to a set point and then the relay will de-energize and power up the charging circuit again?

I think Mart built a circuit like that... though it seems a bit complex...

alternatively there is the ocd circuit just a simple timer circuit switching a relay.

I agree the battery swapper I built was VERY complex for most people.

The best setup I have found is to work with larger batteries, and go for 24 hour period of times. With either a Solar charger on your source batteries or wall current. I rotate my batteries from conventional charge to Radiant charge.

One thing I HIGHLY recommend is if you run these 24 hours a day like I do is to get yourself a 1 amp and and a 5 amp breaker ( something just over the range of draw you are pulling ). Things can go very wrong quick with these circuits and if you are not there to take care of it it can mean you burn your house down. So play it safe put a breaker or solder in some low amp fuses on your primary battery.

Cheers!

That's what I want to do exactly!

My only issue is how to take AC through a FWBR and filter it down to 12V DC. At this point I'm about ready to just throw a cheap computer PSU at the problem, but I really don't want to do that.

Dang it! Where is my audio books. Am I wrong? Do you have to use multitap transformer? Sigh, I guess I could put 150-160 filtered DC through the circuit, but what will come out the other end!

Can we say battery bomb.

Edit: Errr, I don't think that circuit is hard at all. On the contrary

... 24 hours a day like I do is to get yourself a 1 amp and and a 5 amp breaker ( something just over the range of draw you are pulling ). Cheers!

Already ahead of you. It will be out in the shed 50 feet from the house. I have 8 MJL21194's (250V/16A max) attached to a fast blow 250V 10 amp fuse. Hoping I can adjust it to pull 1 amp each. All put in a 1/8'' aluminum box which will be grounded.

psu power supply

I got an old atx psu it works great. Using the +5 volt and -12 volt
wires getting 16.5 volts powering my quad coil solid state.

I also made a cheap and crude low voltage disconnect ciruit using a
relay, 200 Ohm resistor and a 25 Ohm pot. it shuts the load off around 12.4 volts.

And after getting my solid state up and tuned. I am happy to say
my 4 starter batteries are starting to show improvements. Hopefully
soon I will be able to pair them up and start uping the voltage..

I charge for 24 hours on each battery, so I spend my morning
coffee switching batteries and starting the load, and I'm done with
my bedini chores. LOL....

earth ground

Ok I was messing with my solid state and I taped into the earth ground
that I have been using for a few charges now with what seems like
improved results. still early to tell.

when I set my meter to a/c and attach it to ground and then the charge
battery I get over 60V and over 20V to a battery not on charge.
could not get a amp reading or if I did it was .001mA.

anyone got a reason?

Hi folks, hi blackchisel97, reposted here which is a more appropriate thread. Not sure if you've noticed this as I have with J.B. solid state circuit. I'm charge/conditioning a 6 cell nicad 1700mah pack and drawing 400 milliamps input using 13.8vdc supply and when I try the 1 ohm test the input drops to 140 milliamps and volts across 1 ohm show .6 volts and i notice the frequency decrease when making the 1 ohm test and when charging the battery the frequency is at least double if not triple. Does anyone know if when put back on charge battery, is it still seeing the same overall output watts with maybe a reduced voltage due to lower impedance, so as to be in the safe region as per the 1 ohm test. This confuses me since I thought with the blocking flyback diode it was supposed to be independent from input, transistor off collapsing field. It's charging well though and bringing the battery back to life. Any thoughts appreciated.
peace love light

Hi Tyson,

Depending on battery used and connecting wires, impedance being seen by the circuit is less than 1 Ohm. I consider 1 Ohm test just being rough and helping to determine if we operate in the proper range. Of course during this test you'll notice some changes mainly due to the impedance of your load. I understand battery impedance as being dynamic thus, changing. I did notice circuit "tuning" itself accordingly. There is no need to adjust anything during charging/conditioning process. Resistor impedance is quite stable and may slightly change due to the temperature. As long as you're within half a volt over resistor it should be fine (maybe more Jules) with connected battery. I believe, that fine tuning should be done with scope or similar device allowing to see the waveform. I did mention this before in other thread, there is a PC software - Visual Analyzer. Program is free and has a scope, spectrum analyzer, voltmeter, wave generator and frequency counter. Works great and you can't beat the price
I'm playing today with my new toy - Radiant Charger. Similar to solid state but triggered by rotor. I use cap pulser built the same way as J.B Solid State. Different timing, different capacitor. I have a coil with 6 windings but using three at the moment and thinking what to do with remaining three

Where the ground connect to, at charged battery positive or negative? Panacea John Bedini Technology.pdf explain some of the reason for earth ground.

Nicad has low internal resistance. Seeing your result I guess 6 cell nicad still have lower than 1 ohm resistance.

I think that only ok for battery with high internal resistance such as NiMH or Lead Acid. nicad has lower resistance than both about a quarter of them. Based on pdf, 1 ohm resistor test need to be performed on lead accid charging where input current is more than 1 amp.

the negitive was to my earth not connected to my solid state
and the positive was to the positive of battery being charged

I don't think that input current matters. Test is mainly recommended for SSG, on Monopole3 Group. Those simplified circuits draw less than 0.5A. Usually between 0.15 -0.28A depending on setup. My SSG test was 0.15V.

I see. If there is no current then it can not be used to charge the battery or it may surface charge it. The suggestion was to attach earth ground to positive of the battery.

I don't think that input current matters. Test is mainly recommended for SSG, on Monopole3 Group.

I think the purposes of 1 ohm resistor test is to avoid having too much current going to the battery. Agree that it would not be a problem if the circuit draw less than 1 amp.

I wish I could make the wheel version too some day .

I can't find anybody locally "capable" of making decent rotor! I'm stuck with bicycle wheel for now I can send you one
