Can anyone confirm the behaviour of cabin/battery heating that happens in my model 3? Everytime when I start cabin heater from app the battery heater kicks in and motors pull the 7kw like they do when heating battery. Checked from scanmytesla and total battery draw can be as high as 14kw. 7kw for the motors, 6kw for cabin heater and rest for seat heaters, computers and so on. It doesn't matter if charging or not, so not even 11kw charger is able to top that and range loss before driving is very fast and noticeably.
When I was testing temperature was +10C and cell temperature was +20C, so seems like totally unnecessary and wasted energy. It also really adds the total energy consumption, especially when driving short trips at winter times. 15min of heating can now consume as much as 3.5kwh, which alone is about 20km worth of range. Now lets say you drive 10km with 200wh/km, total energy consumption is now 550wh/km! Range loss before drive could also be a problem if already stretching close to the maximum range at cold weather.
Imo this should be behind an option, and if it was, it would be a great thing to have a manual battery heater available. But is this just a fluke with my car and should I contact service center or can anyone else confirm? My solution now is to not preheat if I don't absolutely have to (frozen windows for example). I hate wasting energy so much that it nearly doubles or triples the consumption compared to only driving. Also don't like that something so fundamental basic function of the car changes without notice.
