No, range is significantly impacted in cold conditions even if you do not use the heater. When you first power up a cold-soaked car, it will consume 6 kW for the pack heater alone. Once the pack is warmed up, though, there is still significant impact.
Yea thats what I've found as well. In these cold temps, not only do I "prewarm" the car by turning the heater on, but I also flip it to "range charge" mode so that I can start up the charging to pre-warm the battery pack up. Using the cabin-heater doesnt warm up the battery or anything. Only "charging" the car will warm up the battery pack as well as make sure I have full regen ready. If you can time your charges to complete every morning at the time you leave for work that would work too, but it varies too much for me. When I wake up, I turn on the heat and switch to range charge mode (note: I don't actually range charge the car, I only charge to 80% daily and having 40 amps for 30 minutes is only going to get me a 1-2% up to 82%, but its way more than enough to warm up the battery pack and not have limited regen either.) So the other result is obviously I don't consume that 6kW of energy either as soon as I leave the house. That was always a killer that annoyed me until I found that if I started charging first for 30 minutes that went away.
