Hi All noobie Tesla owner here.

I woke up this morning and was surprised to find that my battery range had fallen 14 miles overnight. This was the first time I've seen such a drastic drop in range in a 8 hour period since taking delivery of the Vehicle this late September. Confused I took at look at the data from the Stats dashboard I'm working on.

From the dashboard I saw this rapid decline:


So I looked at the data behind it which I pasted below. Notice how the Battery Level remains the same at 23% overnight but the Usable Battery Level drops rapidly due to the cold. In the end I'm only able to use 78% of my battery. It's been getting chilly here this week but it's still fall. I dread to think how much range I'll be losing during the actual winter...

I'll be sure to add additional data on how climate affects Usable Battery Level tothe dashboard.

On another note, if you're also interested in a free stats dashboard I am looking for a few beta testers for the dashboard before I open it up to the public for use. You can find my post about it here: Gauging interest in a free tesla stats desktop dashboard
