Some way to heat the car without killing the battery would be amazing. Let it warm the batteries at the same time. I don't care if it is some crazy technology.
The Chevrolet Volt has a heated and cooled battery pack similar to the FFE. I am not sure about the FFE, but, on the Volt, if the system was heating or
cooling the pack, you could siphon some of the heated or cooled air into the passenger cabin. I seldom used my climate control in mine. If hot, I would
put fan on low and when the the A/C kicked on for the pack, the air was cooler, I would then turn the fan up. Same when it was cold. In almost 20K miles,
I don't think that I used the climate control more than a few times. Pretty draconian measures living in Las Vegas, but, I have other vehicles to use if
climate is an issue.
I have only had my FFE since the beginning of November. Other than preheating the cabin on colder days, I have not used the climate control on
it either. Have to play around and see if there is a similar option with it.
