[First Edition]

Yeah, that's not aging well for some folks.

Yes, and it looks like a lot of folks. Not just a one-off problem.

How it started:

Darren Palmer: "The days of surprise flat 12V battery are consigned to history!!!

How it's going:

Dead 12V battery

Deep Sleep Mode - Drained 12V battery

This is really the finest use of the internet. Now if I could just find the right meme.... I feel like I vaguely recall a movie scene or two about "the days of ____ are over" but this is the closest I could get. There must be others.

(And we all know how things ended for poor Jonas...)

I must be missing something here - If the 12V battery is maintained by the HV battery - suppose the HV battery goes dead for whatever reason, then the 12V battery goes dead. Why not just plug the car into a charger? Won't that start charging the HV battery, thus charging the 12V battery?

Yes. This feature goes a long way back to the Toyota hybrid system that Ford pays/paid a royalty for when selling the Escape and CMax hybrid.

I think the LVB has to be alive to sense the charger and connect it to the HVB.

When my LVB died I tried connecting my home EVSE to the Mach E. No lights, no action.
