Powerboost reliability.

Powerboost Envy is a powerful force.
I know, because I once was afflicted.

Powerboost > all other F150 engines


My truck made me post this.

I think that is to minimize any difference of potential between items(power tools for example) and the truck chassis.

No, it's an OSHA requirement, not an electrical safety issue.

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

Well, they finally got the fuel pump, and the engine now fires up and runs. However, the hybrid battery requires an emergency charge, and my shop can't do it. If the Ford technical advisor doesn't get back to the service manager, they are going to tow it to a dealer that can. ?

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.

What? Could the BDS have gone into BDS-G mode due to low HVB?

Demand a fresh HVB now! They can emergency charge some out of warranty battery. You want a new HVB!

I'm sorry--bds, bds-g? I'm not familiar with all the terms yet.

Belt Driven Starter Generator. It looks like an alternator but is used to start the ICE under certain conditions. We were discussing in a thread whether the Powerboost actually uses the generator function of the BDSG to charge the battery. The scenario you described is a strong maybe lol.

That's interesting. I have no doubt I drained the HVB as I needed to get over 2 lanes of traffic when the engine died.

Based on this perhaps?

NFPA 70E, Standard for Electrical Safety in the Workplace

Nothing electrical or safety in that Standard at all. smh

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.
