If you prefer a video overview, jump to this short YouTube video on the topic:

Even with cabin preheating, the Tesla Model S and X does not preheat the battery by default during cabin preheating unless the battery temperature is extremely low.  The result is that regeneration is limited (see picture) and in some cases, …
