No. The cold will cause battery heating and less regen. Short distances when cold are big energy drains, as the energy used to warm the pack and the cabin isn't amortized over a long enough distance to average down.
Neither short trips nor preheating will cause any harm at all. The car is just using more energy per mile than you'd see if your trips were longer, because it's using all that energy at the beginning to warm things up, and as you are moving less miles that'll show up as large Wh/mile.And is that causing the battery any harm? Presumably I can also use pre heating and that’s fine as well?
I believe the car calculates based on battery to motor and misses all charging losses. I expect those to be a minimum of 10% and quite possibly higherA weird ascertainment:
I note precisely the kwh as indicated on the display of the Tesla after each charging session at home. When I compare with the kwh as displayed by my home electricity meter I see a significant difference: almost 20% more on the meter! These measurements are spread and averaged over a period of 2 months.
No other devices or wall outlets are connected with this electricity meter: the outlet for the Tesla is the only device connected to it.
Does anyone have a similar experience? Or an explanation?...
Thanks in advance!
Does anyone know what the usable battery capacity is for the MX 90D? I recall it being lower than 90kWh, but I can't remember the number.
For "90" packs things are even worse. There are about 3500 cars with 90 packs showing < 500 miles with an average usable capacity of 83.2 kWh (or 87.2 kWh total with the 4kWh buffer). Just over 1000 "90" pack cars reporting between 500 and 1000 miles on the odo with an average usable capacity of 82.8 kWh.
Average usable capacity for all ~65k "90" packs in the data: 81.3 kWh with an average odometer of only 11k miles.... that's an average drop from new of almost the same capacity on the 90 pack in 11k miles vs the 85 packs in 37k miles. Pretty crappy.
