Vehicle not sleeping during cold weather?

[jime_r1t]

Has anyone noticed that their vehicle doesn't reach sleep state when the temps are below 40F? The last few days have been cold-ish here (25F-35F) overnight and the truck seems to never get into sleep state. It seems to bounce between Ready and Standby every 20min or so. I thought it was PAAK / proximity issue, but once the temps around here went above 40F, the truck goes right to sleep...

See below.
White: Ready state
Blue: Standby
Purple: Sleep
Pink-ish: Charging
Green: Driving

Another day.. still not sleeping until the middle of the day when it got warmer. I managed to throw together a temp graph with the vehicle states for the last 2 days..

Apparently I need to add code to smooth the weather observations from NPS, it's a little choppy. It's the first time I've actually looked at the temperature data I've been collecting.

Same state color scheme:
White: Ready state
Blue: Standby
Purple: Sleep
Pink-ish: Charging
Green: Driving

I asked the service department about the higher battery drain below ~45F and they confirmed that this is expected behavior. Anything below 5% over 12 hours is acceptable battery loss to them during colder weather.

I also managed to smooth out that temperature graph for those who like data...

10% a day loss in cold weather is acceptable?? More than 10kwh in a day is simply indefensible.

They didn't confirm it's a battery heater, but I'm betting it's a battery heater.

^ If your truck sits a lot... maybe consider this:
