Powerboost reliability.

[imnuts]

It would be interesting to know what SOC the HVB is considered too dead to recharge via the trucks normal systems. I've seen mine as low as ~35% and no issues other than ICE running longer. I'd guess the HVB is at like 10-15% or less for "emergency" charging. It's also wonder how the dealer charges a ~385VDC battery manually.

I'm also interested in why @SportsTechnology can't remedy his own issues being so educated. I fixed all my own software/firmware problems myself with FDRS and I only have a bachelor's in engineering...

@imnuts Why? ?

They have chargers for handling both cell modules and batts. This is what happens when a cell group is replaced in a battery. It's got to be charged to match the rest of the battery. The PB's batt is only ~275v though. The lightning / mach-e are ~380v (varies depending on battery size, higher capacity = lower voltage pack, more in parallel, less in series ie: 94s4p vs 96s3p)

Based on this perhaps?

NFPA 70E, Standard for Electrical Safety in the Workplace

Nothing electrical or safety in that Standard at all. smh

Get serious, there is no requirement for a bonded neutral in the generator. The NFPA will allow either setup. As to the "workplace" that is specifically citing the issue that OSHA adresses. If it is a "workplace" then OSHA applies. If it is a home powering generator, then bonded or floating are both in compliance with the NFPA.

So after being towed to a dealer with the correct charger and charging for a day and a half, it's done, they say. I'm not waiting until Monday--I'm heading to get it now. Thanks for all the advice and for letting me gripe.

Off topic but high five for Wyoming. I'm just East of Cheyenne.

The fact that the engine fired up and ran with a drained HVB. That tells me the traction motor was disengaged via the clutch mechanism or the ICE was turning it from a dead stop. I'm still just beginning to understand how the PB functions.

I'm basically thinking out loud at this point in the learning process and disturbing others lol.

The main 12VDC battery powers the starter motor.

I'm surprised that your ICE can run but the traction motor/generator can't charge the HV battery.

Ford must have some software parameter that blocks charging if the HV battery SOC is below some threshold?

Bizarre to me. But maybe there's something being protected that I'm not aware of.
I do know the Service Manual calls for the HV battery to be discharged for certain repair tasks.

If I understand the traction motor generator, it is a 3 phase unit that requires excitation. The 12VDC battery cannot provide this excitation (actually it could but they didn't set it up that way) and if the HV system cannot provide it, then it just won't get it on. That doesn't mean the truck can't go since the 12VDC battery powers the starter and other engine run system. Many emergency diesel generators can have their field "flashed" with a battery setup... You just need to know where to hookup the battery.

The truck bed and tailgate are clearly designed to be a workplace, which was my point.

Yes. Very good. The Auxiliary Battery Isolator opens during that operation.

Having skimmed over the comments (and avoided the crossfire between some fairly emotional souls here, yeesh!), just a gentle reminder or 3:
1. I think EVERY truck has issues. I followed a Duramax forum (when I was shopping for 3L Duramax trucks) and it was the same. Grown men nearly in tears of rage, usually electrical related: DEF tank level, sensors, etc. Also the long-crank/no-start issue. No parts available. Etc etc
2. Not sure you can really compare historic hybrids to PB. I’d say it’s an order more complex due to the generator mode & additional Hx. All needing more sensors, more connections, more wires. Even my “simple” 5L XLT has easily 10x the wiring/connx compared to our 04 Element. All of which can glitch/fail/not get connected perfectly…
3. It’s 7pm here on a Friday. Let’s all take a breath, crack open a cool one, smoke a joint if you want (hey, I live in BC!), enjoy a weekend doing cool stuff, and appreciate the good things in life. Have a good weekend!

If I understand the traction motor generator, it is a 3 phase unit that requires excitation.

I wonder if the ICE can spin the Traction Motor rotor generating 3 phase current flow which can then be converted to HV-DC for the DC/DC converter even with the HVB fully drained in an emergency. In order to sustain that operation without draining both batteries the BDSG would have to charge the batteries. If the engine fired up and didn't just turn over, it indicates to me the ignition system was powered up.

BISG, my friend.
Integrated rather than Drive

And you are right about the tailgate work surface. In fact we have had a debate in the past regarding Ford EVER marketing the Powerboost as a power source for powering a residence. (Like they have with the Lightning)

Ford has marketed the Powerboost considerably as a power source, but almost exclusively for camping/fishing and contractor tools on construction sites.

Belt Integrated Starter Generator not Belt Driven Starter Generator. I think at this point I just make up believable acronyms on the fly lol. Thanks for that.
