My car spends the night in my garage which recently has been about 5C. When I leave for work there is, not unexpectedly a regen limit even though I turn the climate on 30 minutes before I leave and I try to end my nightly charge at 7am. But after about 15 minutes the regen limit goes away. My drive to/from work is typically 30-45 minutes. I get to work without a regen limit and park in an underground parking garage - usually 3 levels underground. When I leave the garage in the evening my Tesla says that the "outside" temp is 10-12C. So my car has "cold" soaked at roughly 10-12C for about 9.5 hours. So shouldn't my battery be warmer than the ambient temperature in the garage? The surprising thing is that on my drive home I have a regen limit, again for about 15 minutes or so. This must mean that regen limit kicks in somewhere around 15C - is that correct? I would have thought that regen limits would only kick in under 10C.
