3 Battery Generating System

[altrez]

Hello All,

I have started my logging test on the 3 battery system.





We will see how it goes. The plan is to run it down to 10.5 volts and let that charged battery rest 24 hours and then test it.

Hello,

The pretests are still going on lol. I am testing the logging with the moooshimeter and verifying its readings with other meters to make sure its close.





As you can see it looks to me almost perfect with my clamp meter.

I am also testing for heat and I am finding nothing over loaded but my hot hand print left on the table as you can see from my Flir igm amp clamp.



I am getting close to my first 3 battery test that I have ever fully logged. I have tested the 3 battery system 100's of times but I have never logged every aspect of the test. So this time I am going to try to do just that.

Hello Everyone,

I am very close to my 3 battery test. I have setup my Fluke connect logging, my usb logging and my mooshiemetter logging. Its all been tested 14 different ways.

The 2 battery's are as charged as I can get them and I am only waiting for a few more meters to come in tomorrow to start the test.

One thing that i have found interesting is that I tested the split on the 3bs with my Analyzer and it showed this:



That's basically saying that there is less then 40% battery capacity on the split. However it does show the very heavy resistance with the dead battery 3 in place. It will be interesting to see how long it goes before the 10.5 shut off and whats the final charge on battery 3.

Hello,

My test went well on the 1 battery. It matched everything perfectly. Now I am going to let it rest 24 hours and start the 3 battery test.

Talk to Bob French

We know from experience that you want to have voltage higher than the battery to charge it, (a dit over 16 volts is what I set my charging at most of the time, but you can use high voltage at NOT amps or milliamps, but microamps to achieve that charging, as long as you PROPERLY PULSE the batteries.

Hello All,

I have did tons of testing this weekend on my battery's and feel like I have got everything very close to being calibrated to spec.

My first test was with 1.5v D-Cell batteries. In the 3 battery setup I did charge a D-Cell battery just fine and tested it before and after with a battery load tester. It worked! The other batteries did drain of course but it worked.This is the tester I used to verify my results:



I could not hold the tester and take a pic at the same time so you will just have to trust me lol.

My test I am currently running is a load test on what will be my battery to charge on the 3bgs setup. I am running a 20 hour C-20 test.

Here is a pic of the DC load tester please notice it is at around 0.250ma



This is because I added an automatic shutoff circuit to kill the test at 10.5 volts and there is around a 100ma draw with that circuit.



Here is the true current from the battery.



Everything is in spec with theses tests. I am also logging the test battery's voltage.

Lots more to come.

Thank you.

Thank you Chet,
I’ve been following this topic since about the end of 2008.
I don’t think there’s been much,if any, progress since then.
Skywatcher seems to share the idea of pulse changing to the 16v. mark.
I believe the idea is that,with a series of pulses, the higher voltage can be
applied without over heating the electrolyte and “boiling “ it off.
I found that LTO. battery had an anode with crystals that had a surface
area of around 100 sq.mtr. per gram compared to a normal li-ion which
had 3 sq.mtr. per gram.
Domestic storage starts to look feasible when you’re going to get 20+ years
life from a battery coupled with dramatic increases in the performance of
solar panels.
I would very much like it if someone could show me where there’s some
documented evidence for running LA’s at higher voltages. Even if it did work
I would imagine it would be impractical because of the time factor.
John.
PS. I was trying to think of a word and it’s just come to me. “Empirical “

a very cool fellow

Over here post number 98

Experimenter and builder Skywatcher is pursuing what seems to be
a gain mechanism with similar format albeit unique to the claimant .

as always I will remove this post if too off topic

Impressive.

Wow! I could hardly believe this, could it be true?

1. Extremely Long Lifetime

As discussed above, the advanced nanotechnology consisting of lithium-titanate nanocrystals and their increased surface area are especially designed to enhance the lifetime of these batteries. With an over 30 times larger surface area, this technology is able to recharge substantially faster than its more traditional alternative, the Li-Ion battery. The cycle count of a Lithium Titanate battery is 20,000 in comparison of only 2000 in a regular lithium battery, marking a revolutionary approach to energy storage.

[Iamnuts]

New to me.

Apparently these have been around for a long time but they're ne to me.
They look to have a lot of good points, really impressive is the number of
cycles and fast charge ability.

altrez,

probably much better not to think the batteries are literal storage of energy..

the charger applies current to the batteries in order to reverse the chemical process done by discharging..

I came to this realization after charging my battery a few years back by about a week by a small pulsing circuit @ 2amps, only to find it not full at the end (13.8v).. it is a bad 70ah battery that is still usable for small loads.. I always wondered where all the energy went to..
Then I thought maybe I wasn't hitting the battery enough with high voltage so I built a larger pulsing circuit and charged the battery again @ 4 amps, overnight It went up over that..
after that I concluded that the battery will not charge no matter how much amperage your charges uses unless you hit it with a certain higher voltage... that it is a 100% chemical process.. and in no way related to the energy you use to charge it..

after reading this thread I see people telling the same thing..

your charger probably is designed only to charge at a certain voltage..
and your batteries though all new, have different conditions..

nice equipment btw..

good luck with the documentation..

ricards,

Thank you so much for the post. I do agree with you that its all about the battery's chemistry makeup and finding the right voltage. I am not sure how to test part of it yet so I am trying to get as close to I can of some type of starting point for solid documentation.

The 4 battery's all came from the same supplier and are the same type.
