David Bowling's Continuous Charging Device

[Dbowling]

Guys, I actually was done here, but someone on our thread pointed out an error to me, and I need to pass this info along. I showed a video of my razor scooter motor running another razor scooter motor pulling 11 amps. I assumed since my generator I am running with a DIFFERENT razor scooter motor was heavier, that it would pull more amps. Someone pointed out to me that their motor unloaded was pulling less than ONE amp and no matter how much pressure they put on the shaft they could not get it to read 11 amps. I went back and tested the motor running my big generator and it is only pulling slightly over 2 amps. The razor scooter motor running another motor is a disaster. I get different readings with analogue vs digital from 11 amps to 6 amps. When i try to run the motor at the other end of the shaft, it won't even run, and I was using it as a generator. So there are definite issues with these two motors. Luckily I have two more on order. There may also be issues with my meters. I will spend some time this weekend calibrating them.


Obviously this throws all my calculations out the window, so I am shutting my mouth until I get everything calibrated off a known voltage and amp supply. Then I will be back here. I still think I am correct, but at this point I lack the accurate data to support my conclusions.

Still doing that other test though, and I can still run my GOOD motor with the generator, which is what I have been running all along...only assuming 10 amp load when it is only just over two.

David,

A motor draw of 2 Amps as opposed to your meter reading of 11 Amps is much more in line with your previously quoted 18+ hours run time. A robust testing procedure is clearly called for making sure that all run times and rest times are accurately recorded and test equipment is fit for purpose and calibrated. In addition to taking SG readings as suggested by Profitis to get an accurate state of charge, a battery analyser would also be helpful to remove guesswork as to actual battery capacities, especially for those not using FLA's.

Good for you, David. It would be great if everyone would report their problems and errors as well as their successes and positive results.  Criticism from others is often valuable in pointing out problems that we ourselves might miss. Learning comes from analyzing failures, more than from celebrating successes, in my opinion.
I wish you happiness and peace.

backspikes will probably blunten the 4ward reading of ammeters somewhat i guess.depends where the energy of the bakspike is going.

@David
The journey is more important than the result.
I applaud you for looking ore carefully at your instrumentation and your methodology. There are many wise, experienced and qualified people here who can assist with advice and experience.
In majority of  cases I have personally seen and been part of testing it came down to measurement errors or poor instrumentation.
The other is making assumptions what a motor or generator is drawing unloaded.


It is good you acknowledge mistakes, that is how we learn and move on.


One suggestion I always make to inventors ....track and try to explain the energy cycle. Where does it come from?


Many of us who you were thinking were criticizing were actually trying to help, some of us  lack diplomacy skills




I wish you the best
Kind Regards
