And don't panic that the car needs to be plugged in all the time. My car is parked outside each workday (not plugged in), and no issues last winter or this winter with the 12V battery.Robert123 wrote:We haven't had the car long, and it's rare when it isn't used every day. It just so happened that I had to get a load of poulty feed one day (drove the truck), got the daughter's car lined up the second day, and snow hit on day 3 (very rare event here) so i drove the AWD vehicle. Wasn't cold when this cycle started, so I had never seen the message before. I live in SC. It doesn't get into the 20's here very often at all, let alone approach single digits . BURRRR. I live down here for a reason
Software update is definately on the horizon. Car reminded me again this morning when I got to work. No outlets around here, so I'll probably take it out at lunch to insure the 12v stays topped off. High is only supposed to be 32 F today, but southern weather returns tomorrow . Looking to take it in on Thursday. Thanks again.
My FFE sat out in the cold northern Ohio from before Turkey day until after Christmas. I was getting rid of my old car so I parked my FFE and used the old car full time until it was scheduled to be my nephew's first car. My FFE was not fully charged when parked and left unplugged outside the whole time. I kept waiting for the dreaded "12v low" text that never came.scottt wrote:And don't panic that the car needs to be plugged in all the time.

I don't think I would trust this 12v battery without getting it checked out (load test, etc.). Very little juice is required to start the FFE compared to cranking an ICE. I had a very sick 12v battery for a while that still managed to start the car most of the time. It eventually degraded to the point of, apparently, having <1 amp-h capacity remaining. If it had been recently topped up by the DC-DC converter from driving around, or topped up with an external charger, it could start the car just fine. OTOH, if the car was off for more than a little while, the 12v would be too depleted to operate the relays to hook up the traction battery. The voltage drop while starting was ridiculous.Robert123 wrote: Got a voltage meter. 8.5 volts on the 12v battery. What the heck????
Went back to barn and got the jump box. Hooked it up and the car went back to normal. Level 2 charger kicked in. Battery charger shut down after about 4-10 min saying battery was charged. Apparently, the level 2 charger was now charging the 12v battery based on the voltage at the battery.
