Powerboost Propower and locking/double-honking/starting/parking/camping

Ah! Thanks for digging into the gritty details, I have not messed with Forscan at all, I'm afraid I'd go down the rabbit hole and want to reverse engineer everything.

So that must explain why even at light light loads, it can still do a few engine starts within short times of each other. i.e. it doesn't automatically charge until full, which is surprising!

I turn on Eco Idle so that the battery charges faster. But I guess it still decides "eh, I've had enough for now" and stops charging.

What I wouldn't give to be able to see HEVBAT_PWR_REMAIN in the dash and on Fordpass, it would help let us know how long we have before the engine kicks on, and can manage quiet hours better. Like I may want to sit in the driver seat and put it in tow/haul or sport and have it charge to 100% just before generator hours end and quiet hours begin.

That's where it gets even more interesting. Even when the battery was at nearly 50%, it wouldn't charge while I let it idle in tow haul mode, or even when I held the gas to maintain 1,500 rpms. The truck decides whether it charges or not whether the battery is low or not. Very intriguing.

What??? Why would it stop charging? Man, we have a lot to learn about these things. Perhaps that is just how it operates in generator mode, only 50% capacity. Whereas the higher charge capacities are used for driving?

I'm guessing you cannot use forscan while driving, and not requesting that. But I'd love to know what ford's reasoning is here.

That's how my Hybrid RAV4 behaved while it idled. It would get to about 40% charge before ICE kicked in, battery would charge a bit more than halfway, then it would go back to battery only.

I can't say why it's done that way, but it's not just Ford. If I were to speculate, it likely has to do with battery longevity and health. Keeping batteries healthy and long lived requires a complex balance of circumstances, some of which includes temperature and charge rates. I suspect that the engineers have vehicle behavior dialed in quite tightly to ensure that the batteries discharge what they are supposed to, when they are supposed to, for how long they are supposed to, within the boundaries of our stated warranty.

Here's some reading that can shed light on how complex of a topic this is:
