A few folks have observed the fans coming on when plugged in at 120v, so I think we can presume the battery cooling system does function even at Level 1. It would make sense that charging would take noticeably longer if cooling (or heating) were needed while charging at Level 1, since the overall incoming current is limited.davideos said:I think it does...but not 100% positive. In the summer when I was plugged in at work, there were 2 observations I made.
- On hot days when plugged into work outlet at 120v, it took longer to charge. Either the car was charging slower or it was using some power to cool the battery.
- Again, on hot days at work, when I unplugged before charging was complete, I'd get a message indicating that the battery was hot and needed to be plugged in.
TMS is not active when the vehicle is turned off and and not plugged in.pwebb said:By this experience it would seem that level 2 is needed to activate the TMS even when the battery is charged. I have a email out to Ford and will post their response. Any thoughts?
Its off: I cannot plug in at work and I see no battery degradation (either battery) when it sits at work for 8 hours. So far its been fine in temps as low as the 20s F. (I have yet to take it to work this year due to the REALLY cold weather--will most likely tomorrow and it will sit all day in 10s F temps not being plugged in and complaining about it!)GladeStorm said:I'm not convinced that TMS is totally shut down when the car is unplugged- my 12V battery never got drained until the overnight temperatures dropped below 40 degrees last Nov; then it happened multiple times until I decided that I needed to leave it plugged in on cold nights. (Might be part of TSB 13-9-19 that I haven't gotten around yet)
Btw, I mentioned TSB 13-9-19 when I took my 2013 in to get all the recalls applied. When returning my car, the service tech was kind enough to follow-up and explain that the TSB was superseded by the recalls. So, I'm not sure sure if that TSB even applies if you car is otherwise up-to-date.GladeStorm said:my 12V battery never got drained until the overnight temperatures dropped below 40 degrees last Nov; then it happened multiple times until I decided that I needed to leave it plugged in on cold nights.

Yeah I was talking about the dash--I only have 1 MFM notification texting me (charge fault) and none of them e-mail me.dmen said:BTW, you may already know this, but you can disable the complaining about the cold, at least the text complaints. Use "notification settings" under "my account" on myfordmobile's website. Since I can't do anything about it at work, and it's usually obvious that the weather is particularly hot or cold, I don't see a reason for my car to bug me about this. Wish I could disable the instrument panel complaining too.
I wonder why they use so much power?jeffand said:I know that the cabin heater has two 5 kilo watt heating elements. Since level 1 charging can't supply this level of power the difference has to come from the battery pack.
