FWC that graph does not show the current and Bulk vs Absorption. The battery voltage rises all the way through both stages in LFP and FLA.
Looking for more examples like in previous post showing when Bulk ends with 1C. One is 70% and the other says 60%. I saw one where they said at 0.5C, Bulk ends at around 90% or so. 97% would have to be at a lower rate than 0.5C.
To run a race against time :) we need a start line and a finish line. since the FLA looks bad for the last lap, FLA wants to make the finish line at 90% SOC, but the LFP guy insists on timing to the last electron into the FLA.
Also the LFP guy says he is full when amps taper to 5% of C. The AGM wants 0.5a/100AH so that is going to take a while. BTDT-watching paint dry.
Starting line is another issue. the graphs seem to be using "depleted" to "full" as the course. The FLA guy says to start at a higher SOC so the LFP 4x has less time to run before Bulk ends, and the LFP guy wants to start with zero%.
for this exercise we could pick some sort of finish line that is not extreme--after all Absorption goes to infinity, so you have to declare it is over somewhere. and use zero% for the start.
Then we could do another one with more real life examples such as 20%-90% or whatever. If we are doing this to compare gen times (seems to me that would be the reason to get faster charging) then you always stop the gen at 80 or 90% with FLA. Silly to waste time and gas on the 90-100. OTOH you don't usually run the FLA down so low as 20%. But if you don't use a low SOC, the LFP guy says no fair, because he does better the longer the Bulk stage goes.
