Here are some updated stats. A few things to keep in mind:
- It's my wifes car, she works at home, so not that many miles.
- At home, we charge it to 80% with a Level 2 charger
- Most of my Tesla Superchargers are in Dows, Iowa. My mother lives on the Minnesota/Iowa border and about 1/2 the time we take the Tesla.
- A few thousand miles are not accounted for in these calculations. I didn't run the software in the beginning, and I had a stretch where it wasn't logging and I didn't know. The 12k miles on the odometer is correct though.
- I'm surprised this software is still running. Tesla was supposed to turn off the free API a few months ago.
These are the current stats. It's currently sitting somewhere in Ankeny. The battery is at 73%, which means it has 229 miles of range left. She has the air set at 66 when she is driving, and I'm guessing she has it sitting in the sun because it's 125 degrees inside. The glass tops really bring in a lot of heat but she has white leather, which helps. If we lived somewhere warm, I would find a solution.

This gives some stats on the battery. With 12k miles on the battery, it has a 3.8% degregration. 3.8% is pretty high for only 12k miles, but that's common at first and I'm seeing it start to slow down. It sounds like if we kept it 200k miles, we'd see around a 15% degregration, which means the range would go down to 280 miles. The battery has an 8 year/120k mile warranty, which is a lot longer than we'll keep it. Once we retire in 5 years or so, I'd like to move to 1 vehicle, which will 100% be another BEV.

Total charging cost and average cost per kWh are a combination of both charging at home and at Superchargers. My home rate is 0.11 kWh and the Tesla Superchargers usually run around .40 kWh. Unlike other areas, I don't get a discount based on TOD charging, although 11 cents is pretty cheap. As you can see, 99% of the time we're charging at home.
For comparison, my Kia gets about 21 mpg overall. If I paid $3/gallon and drove 11,164 miles, it would cost me $1,594 vs. $474 in Electricity. Plus about $400 more in maintenance on the Kia. Plus the Tesla is faster than the muscle car that I had that got 10mpg and broke down every other week

This will give you an idea of what outdoor temps have on efficiency. Keep in mind that my wife probably doesn't help this stat since she'll preheat the car before she goes anywhere in the winter.
