"PSOC walk down does not mean this capacity loss is permanent, just that sulfate has formed and is not allowing the same amount of "usable" energy to be stored in the battery at the same charge rate and duration as the cycle before."
Wouldn't this indicate that we are all being distracted byissues like high-amperage 100% charging
, when the real solution is to pay attention to desulfating? Which in turn means looking again at concepts like high-frequency pulsing, perhaps at higher voltages than are normally used in obsolete 3 or 4 stage charging
, and crossing the line into equalization
, and in general, re-examining the conventional simplistic charging strategies?
Since microprocessors and MPPT
systems can vary voltage and amperage and frequency on the fly and about as easily as flipping a light switch...Perhaps it is time to examine the real factors and some novel (or at least, not currently accepted) ideas about how charging should be done in the first place.
Oh, and the feds are looking at a zinc-manganse battery chemistry that everyone thought would be useless fifty years ago. Except, now they've tweaked some of the molecular issues, and their quiet murmurs are that IF it works out, lithium will be a has-been as well. FWIW. (There's a shortage of news on the topic, so don't place any bets yet.)
