Hybrid 12-V battery settings and options - used or not?

[HeyBales]

I don't have a constant monitor on - but the drop I get shows it's about the same.
Seems like bad battery too that just can't hold a charge above a certain amount, like a bad cell.


My theory that I may not have expressed in a post yet - but related to that hourly thing.

Sprint had 3rd parties with modem only hardware - Sprint didn't allow maintaining a constant data connection like WiFi does if no actual data being used, because it would use up a limited resources channel and assigned bandwidth - used or not.
So the 3rd parties would get around this by pinging their monitoring server once an hour - just to keep connection up anyway in case modem needed to be reached remotely. Or maybe the monitoring pinged the modem.
Either way, it had to fully wakeup to transmit, that meant full power. Not alot in the scheme of power usage, but more than nothing.

I have no idea if ATT has similar requirement, or if current LTE has same limit on resources.
But you don't want a modem that's going to allow a potential remote start to give up it's access and not allow a remote connection.
I thought current cellular systems were beyond that - but then again, talking potentially older cheaper hardware modems here!

And then the issue the SSM talks about - draining the battery so much it can't start, could be a bad loop where it's not waiting an hour, but constantly awake - maybe it doesn't get an Ack back from the Ford server, so it says lets try that connection again ... and again .... and again.

Ok, back to seeing if those Forscan changes effects the charging rate - nice and thanks, good idea.

Hadn’t thought about that rather obvious cellular possibility! I’ll try just turning off the connectivity, and see if hourly voltage dip still happens……..Bill P
update 1/17-
Graphing before turning Connectivity off:

After turning off: still slight variation, but no constant 1 hr dips

So, this tells me, what we’ve known all along, it’s an ongoing draw on the battery
And because the PCM isn’t telling the DCDC to charge at a rate between 4.5 and 13.5 amps…….., the battery never is able to achieve a high SOC !
Of course you could always take a 12 hour ride, as Ford suggests “ drive more”, to allow that 1 amp charging to do something over a longer time! Bill P
