One thing that got me really exited about Tesla S is the fact that via an app I could start the heater and get out into an nice warm vehicle. No stress getting frost and ice covered windwos clean. Just sit 5 more minutes at the breakfast table sipping hot coffee waiting for the heater to clean all windows.
To my surprise I discover that even when plugged in to a charger heating the car before driving will actually drain power from the batteries rather from grid. Why is that? Does it even make sense to drain battery power heating the car as long as the car is connected to the power grid? Why not just drain power for the grid to heat the car - that way you can squeeze a little extra driving range from the batteries.
Also I have read that Tesla has developed some smart software that manage the charging process. Always taking care of of batteries durability to maximize battery life. Yet reading this forum it seems people are not too sure about this software. Is there any glitches or have people found it to be faulty? What is the best way to care properly for the Tesla? Park it as much as possible plugged in to the grid? What if I go to travel and stay away for 2 weeks. Can the car stay plugged in all that time without "cooking" the batteries - or does the smart software regulate so well it is not even a problem?
