I noticed that my range had dropped by 3 miles every time I parked my car when out running errands. This is in Wisconsin with 30 degrees and wind. I don't understand why the range would drop that much just for being parked. Any help would be nice. I am seeing average mileage to be around 165 when full now that it is cold.

It is probably a result of the short trips. Running the heat at low driving speeds, and then parking means low average speed with constant heater use, so the moving efficiency drops. Just ignore the GOM if it bothers you. All that matters is how many bars you have left anyway.

My guess would be passenger compartment heating. Every cycle the car is shut off, if it sits long enough it measures outside temp and passenger compartment set point and calculates how much energy will be needed to reheat the cabin.

Try this:
start the car with the Heat/AC on
Observe expected nominal range
turn off the heat / AC
Observe the new nominal expected range estimate

I have actually seen my range go up after leaving it parked for a while.
This happened to me today. Left the house at 32F and when I parked the car at my destination it had six bars. 3 hours later, the outside temp was 60F and the car showed seven bars of charge and an increase of range on the GOM. Definitely a function of temperature.

Right kind of like a big air compressor tank. Fill it up to 160psi, then after it cools down its 150. Or charge your RC batteries up to 4.2 volts a cell in a cold shed at night. Then the next day at the field they are 4.3 volt.



IIRC my car tends to go up in miles as I let is sit.
