Increasing Usable Powerboost Battery storage capacity

[HammaMan]

It's easy to monitor how much "power" the electric motor is providing during ICE-on driving. The PID for Amps/in-out of the High Voltage battery is a direct correlation to what the motor is drawing. However a small percentage of the draw is the portion being used to maintain the 12V battery-system, but if you sat idling for an hour and watch the draw on the High Voltage battery when the ICE is off, you would get an idea of how little that draw is compared to the electric motor being used for propulsion.

In other words, if you are driving while the ICE is running, and you see +2 or 3 amps being pulled from the battery, that's NOT the electric motor providing even 1% of the torque request.
But if you have the truck set to cruise control at 30mph and you are in EV mode, you KNOW that the 20amp draw on the High Voltage battery IS what is propelling you along at 30mph.

When the ICE is running, the 280a generator starter handles the 12v system. The AC compressor is still HVB only though

Thanks.
I know it's there, but I have never been clear about how it's leveraged. (starter generator)

Just out of curiosity, could this OBD reader also be used to make changes via Forscan?

Yes

Some home work shows the starting is handled by either a regular geared 12vdc starter or a 12vdc starter/generator driven by the serpentine belt. As to the AC power source it is a high voltage source and either comes from the motor-generator in the transmission or the HV battery depending on whether the motor-generator is driven or not, EG its plugged into the HV bus.

I would be perfectly willing to give up an inch or two of payload capacity for a drop in Aux Battery that fit right into the truck bed.

I'd be perfectly willing to give up some cargo "space". I'd be hard pressed to give up any more "cargo capacity". I tow a lot with my Power Boost machine. I need all the cargo capacity I can get.

As many have said, it'd be perfect if Ford offered the HDPP package with the PB.

I monitor the SOC, as well as the Rate of charge/discharge in Amps.

Mine operates on a consistent basis between 42%<>63%

It's true that some unique circumstances can bring it below 42%, and some circumstances can bring it above 63%, but after many many miles of flat-landing, I consider it NORMAL to be 42<>63

Based on the circumstances that occasionally gets it above 63%, I would assume folks that live in hilly conditions are far more likely to see a SOC in the 63<>70%. I say that because the one circumstance that it appears Ford doesn't squander, is regenerative braking. If my truck is already at the typical threshold of 63% and I have an opportunity to apply regenerative braking, THAT is when I have seen SOC above ~63%

I would LOVE to be able to "tune" the factory parameters to expand what on my truck is 42<>63 to 30<>70

Here are the PIDs I watch for the Hybrid SOC and Rate of charge/discharge

Snakebitten, What exactly (brand, model, and where did you buy) are you using to get the above info? I'd like to do the same and want to be sure I get the right hardware. Nice choice of truck BTW, I also have a 2022 King Ranch.

I think this thread has the most information regarding.
