I've been driving a 2013 Volt for the past 10 months. Today I just emailed my order for the P85+ to tesla. The Volt, when plugged in, keeps the battery conditioned at around 86 degrees the way I understand it. I asked assistant manager questions about battery conditioning when plugged in to a charger. My concern is when it is very cold out. He tells me the battery doesn't warm up until the car is turned on. He says acceleration and regen braking is limited until the battery is warmed up. This is not like the volt. The battery is keep at a certain temperature. Can anyone verify this?
I have a thought. Maybe Telsa doesn't keep the battery warm because it would take to much energy? In the Volt the battery is more or less inside the car. So it's easy to keep warm/cool. Telsa the floor pan is a giant heatsink. So when it's -5F outside the battery heater would run constantly. Which would use a lot of energy. Especially is the car sits for a long period of time.
So I have other questions. When the car is connected to utility power and one uses the phone app to warm or cool the interior does it draw off the battery or utility power. It only makes sense to use the utility power to preserve the battery energy. But I couldn't get a for sure answer on this. And I read elsewhere that the car may draw power from the battery.
Before I bought the volt I found all kinds of technical information on how all the systems work(power train, climate control, battery, etc.) and lots of videos on YouTube. On the Tesla there is pretty much nothing. I'm thinking about trying to buy a shop manual or something to learn how the Tesla works. I hate to say this...I'm buying a $125K car with the understanding that some of the systems are not as advanced technologically as I think. Someone PLEASE prove me wrong! :)
