If you have followed the battery issues for any time - you've seen reference to Forscan says the Hybrid is setup to use an AGM battery already, and charging scheme, with an 80% SOC setting also seeming to be meaningful.
Some that get new batteries (AGM or FLA) change that setting to 95%, with comment it works great.
Of course that just changed 2 variables - so which was the improvement - setting or new battery?
Several with scanning systems also report that despite that setting change, 80% seems to be the top level SOC seen.
Some of us see nothing better than 65%.
Some report new battery issues down the road.
The default charging scheme seems to be the same that many makes/models use with alternator controlled by PCM/ECM - high charge level during starting run time, backing off to lower charge level as time goes on - sooner as you get closer to 80% SOC (65% for Maverick). That will change if the system load is high to higher Voltage charge (not on Maverick as DCDC-Converter supplies 12V system separate from battery charging Amps).
So I'm hoping someone with computer Forscan can really look at that setting, and these other settings.
I've only got Forscan Lite on android, and when I show any of the PIDs that are specific to battery - while they have a setting to use, they don't display that any is used. I'm thinking the whole batch isn't used.
So I'm wondering if it's a batch of settings left over from the software in other models, or included for potential use and then didn't use it, or figures are set, but nothing seems to care about them?
Here's what the PID's display during running. I'll mention other hard set PIDS (like reference Torque value, or user setup for TCU comm) do display correctly with their setting, whether options are available in it or not.
This is not an issue of scrunched screen not showing the selected value - there is no value to show.
Here are the options available to display for those PIDs, if one was actually checked. The example check mark you can discern happens to be in the middle merely showing an option could be selected. Battery Capacity and CCA has no values in them, nor are any displayed.
This is where I'm curious if the computer Forscan merely shows AGM at top of list because alphabetical order, and it's not actually checked to be used. I've not used that program to change any settings, so I've got original data.
With as many reporting that their scan gauges never showed being at 80% either, I'm wondering if that's a setting actually used by the charging logic.
Especially when ones have changed it to 95% and fail to see a change to the max charging level.
I'm really wondering if the values used by the system are totally based on what's seen during the 8 hr relearn with doors locked, and either that is coming up with bad figures, or sensors are bad for really calculating Amp flow, and micro usage to determine SOC by the end of the 8 hrs.
Because these values do change regarding Battery Charge/Discharge, mine are at 6 now for top 2, still only 1 (Ah perhaps?) for Discharge during sleep mode. Which I've never gotten a warning about on Fordpass app.
Any takers on Forscan program, with pics of the options displayed for these PIDs regarding Battery?
