  • Circuit to Automaticaly Swap Batteries on the SSG?

    Wondering if anyone has seen (or can come up with ) a circuit that can swap the batteries on the SSG when the primary gets to a certain voltage... the simpler the better!

    I don't have any experience with a 555 timer though from what I understand it might be able to do this.

    I heard Bedini had a motor running automatically using some kind of relay.

    Cheers in advance!

    yes I also would be interested in this,

    But also a voltage regulator controller like a solar panel controller ,

    ie if im charging lets say a 50ah battery it will disconnect the battery from over charging , also disconnect the load if battery voltage drops below say 11 volts , I want to try my solar panel controller , but im afraid the high spikes will blow it up .

    I have tested that I can charge a battery on the sg and also run a load ( light) directly from the battery , with the light only being turned on intermittantly battery is always charged ,

    but also Ive found that I tried a 10 watt light bulb ran the light for ten minutes and checked the volatge drop , I then hooked up the Sg , ran the light again off the battery while connected to the Sg for ten minutes and the voltage drop was 1/4 of the drop without the sg , so therefore can last 4 times longer ??

      Auto Swap circuit

      Directory:Bedini SG:Replications:Monsieur Bonheur-SG - PESWiki

      See Battery Swapper schematic .


      I have been debating doing this or getting a usb device that you can program to control the batteries. ( have seen such on other forums )

      I currently have a servo that I can control from my computer via USB. I was thinking doing this or using X-10 ( I could use it to control a relay circuit after X amount of time. )

      Someone has made a pic curcuit over on yahoo groups that will shut off the batteries when it hits a programed voltage.



      From what I understand from Rick, the new device from r-charge.com will be able to hook up to a computer to get readings ( but that is still in development)

      But for me, My golf Cart batterries run for over 24 hours pulling 1 Amp, so once a day switching is not bad at all.
      See my experiments here...

      You do not have to prove something for it to be true. However, you do have to prove something for others to believe it true.

        Thanks for the find!

        Though the schematic looks way over my head I expected it to be a challenge but that looks too much! Looks like you have to program the chip as well and run the circuit from your computer? Way over my head! Shame, since it sounds ideal... sparkfun are selling the complete boards in case any one else wants to give it a try!

        I like the servo idea... i used to have manual switches in the circuit to swap the batteries that could probably be automated by servos...

        I m sure there is an easy way to use a 555 timer to swap the batteries every 12 hours (for example) though I haven't used one before so don't know where to begin! Been looking at zener diodes as well but I don't think they would work

          You can do this with a FPDT relay really easily. I was just thinking of this recently as a matter of fact. I don't have a schematic but basically you just set it up to switch routes from one position to the next, leaving the batteries on the neutral terminals.

          However to sense the voltage of the batteries and switch them you would need an additional circuit to do that. However there might be a way with some transistors etc. All you have to figure out how to do is to have it switch when the main battery drops below 12v.

            Tesla Switch

            I think what you guys are looking for is a Tesla switch. It is used exclusively for swapping batteries. Since there are so many links out there on the subject you should Google *Tesla Switch* and find one you like.

            Good luck to y'all.

              That battery swapper schematic is not that hard, and the principle is simple. I would extent that further though and instead of a RS232 have a USB connection so that a "log" stored in a separate EEPROM could be dumped to the computer if user desires and an application could plot the data into a meaningful graph.

              One could monitor half a dozen batteries connected and log their behaviour across set period of time and many other things. It's really your imagination that's the limit here.

              Oh, and you would not need a computer to run this, the PIC chip is a micro-controller and has everything you need.
              Are the ravings of a lunatic signs of a genius?

                I aggree that using Pic or even other micro controllers are a good idea, but not every one will be able to implement this and it's not exactly an entry level programming/electronics project. I've been looking into programming microcontrollers and plan on going into it when I have a little more time/money.

                Still, this can be done with basic electronics without having to have a micro controller set up for it I think.

                  Tesla Switch

                  Here is the link from the man himself, JB!

                  Link; THE TESLA SWITCH

                  I've also got a .pdf on it.

                  Aaron has done a video on Google with his reel-to-reel motor.

                  Also; The D3 document from Patrick Kelly's site has lots on the subject.

                  I have a ton of info on it but how do I get it to y'all?

                    tesla switch looks interesting but I can't see how to hook the SSG to it? It looks like it runs a regular dc motor...

                      No no no, the Tesla switch is a whole different Opera and is not usable for SSG battery swapping needs. I have some experience with the Tesla switch and there is far easier ways to swap batteries for your SSG.
                      It's better to wear off by working than to rust by doing nothing.

                        a modification of the tesla switch might be able to do it though i'm not sure what the trigger is to swap the batteries... all the schematics I see are designed to swap the batteries hundreds of times a second which looks like is done with a pwm so wouldn't that be timed rather than triggered?

                        mrbreau... have you seen a schematic for a tesla switch that can swap the primary for a secondary when the battery voltage drops to a certain point?

                          Tesla Switch Revisited

                          Some may remember that this topic was discussed at another thread here in August of last year. Here is the link to that topic.

                          Link; http://www.energeticforum.com/renewa...la-switch.html

                          There are links in this thread to take you to schematics and other information.

                          And Sephiroth, the schematics I've seen use a 555 so they are NOT triggered, as you said. I personally don't see the need for triggering the swap of batteries. Then again, if I knew so much why am I doing all this research?

                          BTW, you video showing how to build an SG is fantastic. It cleared up some of the mystery for me. I am in the process of assembling two right now but progress is very slow since I have to think out every move I make. One is a twenty inch plastic bicycle wheel and the other is a VCR capstan. Because it is a learning process for me there have been mistakes which had to be corrected.

                          I'll have some pictures to post when something positive happens......like I get to charge a battery or two.

                            sorry, I still don't understand how to use that schematic to swap the batteries on the SSG...

                            I was thinking something along the lines of this:

                            batteryswapper3.jpg

                            though, like I say, I don't really understand how to use a 555 properly so if someone with a bit more experience can finish off the circuit (or tidy it up) I would be really grateful!

                            It should work in principle.

                            basically the zener diodes are 12V so as long as the voltage in the battery is above 12V the current should flow through the zener diodes and bipass the 555.

                            But when the voltage drops below 12V the current is diverted into the reset of one of the 555s and the trigger of the other one.

                            this (should) turn one pair of relays on and the other off so the batteries swap their position in the circuit until the other battery drops below 12V and then it swaps again...

                            I have marked where we would hook the SSG schematic to this circuit (primary positive, secondary positive, etc)

                            Anybody got any ideas or can help tutor me?

                            Jetijs... did you say there was a simple way to do this? lol

                            EDIT : Just noticed the grounds should probably be connected... have editited the schematic

                              Circuit to Automaticaly Swap Batteries on the SSG?

                              Well, actually such a circuit does exist. At least the most important part of it.
                              I'm using such a circuit with wonderful results but using a conventional charger .That situation will change soon.
                              Remember that when John Bedini talks about his work, you'll encounter in his speech an almost magical word: flip-flop. Ring a bell ???
                              SG, SSG and Tesla switch are based on it.
                              Then why don't we use it for everything else?
                              To keep it simple: almost every inverter or UPS has an alarm circuit that triggers when your battery is discharged below 10.4V. Some models will ring at 11V. From Mr. Bedini's point of view, the higher the alarm voltage on your UPS, the better (because of the C20 rate). Right?
                              Use that signal from the alarm circuit (can be a buzzer or an LED, or both) and drive a simple 555 flip-flop circuit with it, wich in turn switches your battery banks via relays. Here is an ideea for your inspiration: FlipFlop
                              One bank to SSG for charging and one bank to your inverter. In that split second, your inverter won't see the swap. Even if it does, it will keep its mouth shut until battery discharge happens again. And then, flip-flop again . And so on.
                              That's what Mr. Bedini expect us to do and as soon as I finish my SSG, this is what I intend to do.
                              I currently own two APC 1200W (sine wave), two 350W 3Com's rack mountable (triangular wave) and an 1000W (sine wave) Blazer UPS. Those 3Com's will light my house because a light bulb does't care about the triangular wave and those 700W are more than I need.
                              I also have a bunch of auto batteries taken fron the scrapyard and half of them are dead. Won't take the charge with a conventional charger. As long as an SSG revives dead batteries, I'm on the right path. Anyway, I intend to scale everything up and run at least half of my house needs (if not entirely) almost for free by using only the inverter part of my UPS rack.
                              An another "free" advice. Stop spending top $$$ on solid state relays and the rest. All you'll do is empty your pockets. Use scrap materials like I do. Instead of using a 200$ SSR I use a simple relay wich cost me nothing. Figure the rest.
                              Remember that we were not supposed to change the schematics wich Mr. Bedini shared with us until we understand what those circuits really do. And why change something that works? What exactly do you expect to improve? Charging time? What for, as long as it happens almost for free? Why use an expensive FET instead of a humble 2N3055 built in 1979? It does the job? Then it's good for me if it helps me to reduce my bills down to zero.
                              Regards, and take care.
