So today it's 34 degrees in Boston, with ~1" of snowfall. I figured it was a perfect time to stress test the heat pump and see what the car can do. I turned preheat on HI and have kept it on for a bit over an hour and made the below observations. I'm not sure if this is normal or not, so I could use some help:
- 1 Hour of preheat on HI, while plugged into NEMA 5-20 drained 7% battery. I'm ok with this, but I believe it represents ~7kw draw for both cabin heating and battery conditioning. (7%*74kw)+1.760kw
- The interior maxes out at 80 degrees on HI. Which is about 45 degrees above ambient. I'm wondering if that means the interior temp will max at 60 degrees when is is 14 degrees out, and 46 degrees when it is 0 degrees....
- The glass roof turns into a rainforest due to the humidity inside and the snow on the roof, the rear headliner is moist from the condensation dripping towards the rear of the roof
- The windshield defroster is terrible. It defrosts about 80% of the driver side and 50% of the passenger side, pictures below, you can see where the condensation remains fogging the view. Also, the defrost heat did not feel warm compared to the 80 degree interior temp, it was actually cold.
