Try doing a remote conditioning while still plugged, an hour before you jump in the car. It could increase your range to near 53 even if the weather is colder.
This gets me sometimes. I have a gen1 and my wife has a gen2. One blinks and one flashes all the time!If they are on a 2017 IIRC it is flipped from the Gen 1 volts. Sold green means it has finished and flashing means charging.
