solar pulse charger?
« on: November 30, 2007, 06:05:11 PM »
still not available and not even conceived of by anyone to my knowledge :-(

If you don't mind the 9W max rating, here's one smart charger www.tunecharger.com

They also sell a pre-programmed chip that allows anybody with enough electronic skills to make their own scaled projects.

It seems there are two schools of thought one is to set pulse width modulation to  effect the lead and one  set the pulse width to effect the electrolite .

The main point about the PWM is to avoid wasting power in the electronics, IMHO.

My current circuit on the bench is a base Half wave rectifier from high energy single phase It kicks in at an Rpm that matches battery impeadance ( or a harmonic ) untill the battery reaches a mis match and kicks out to regulator .I working on sampling now any help would be big time Beuno .Here's the base circuit to a 12 24 bank .

pulse width modulation from solar panels

Morningstar's method of charging seems to be a secret. If they charged at 2 to 4 MHz then it would qualify as the first charging/desulfating 'controller'. maybe I'll give them a call and report back.

talked with Morningstar tech support

Their chargers use 300 Hz and do not apply this until the battery is over 75% charged. They do not anticipate making a charger capable of desulfation or a charger that will pulse charge a battery through its entire cycle at this time.

implication: anode and cathode/different pulses
« Reply #8 on: December 05, 2007, 10:17:11 AM »
Efficiency could get iffy on a solar powered pulse charged system as mentioned above.


Then the problem of treating the anode and cathode differently (after the above was accomplished) should be considered.


pushing the envelope here......so I'll probably try D. Denhardt's 100 amp beta prototype desulfator and tackle the pulse charging later.

question...frequency/impedance
« Reply #9 on: December 05, 2007, 10:25:18 AM »
So, the resonance point of the electrolyte/plates could be sensed, pulsed at 2-4 MHz and then would drop out when voltage became too high or the charging/desulfation was no longer needed?
