Ford REALLY doesn't want you to kill it.

Polarization is why you see a battery shut down, but if you turn it off and back on, it will work a little longer. The voltage will rebound (either up or down depending on if you were charging or discharging) and a voltage based BMS will allow operation again.

This is VERY bad for an NMC Li-ion cell. You are effectively over discharging the cell. Because the BMS designers KNOW people will try this, the Ford BMS will have a buffer to keep you from going into the abuse area.

While your truck will not allow you to go below 0% SOC (yes I have taken cells below 0%) those very low SOC levels WILL cause some damage to the cells.

Interesting aside; some of the standards call for taking a cell to 100% negative Vmax, i.e, take a cell down to -4.2 V.

Got mine down to 9% yesterday. Something weird I noticed is the difference between the guess-o-meter when you have a nav route active vs not. Seems if you have the nav active it makes a lot of assumptions about your route, whereas if you have no destinate set, it just uses the current efficiency per mile to guess how far you could go at the same speed and conditions. On the highway this is kind of annoying, it must assume I'm gonna drive 75mph, even though I was purposely driving slow to make sure I get home. The whole way on my trip the nav said I'd be at negative 20 miles at my destination, I made it home with +17.

You’re only up to 326?!?

No, this isn’t a new reason. There have been others discovered after this one.
