Don't sweat it, don't let your life be ruled by a report card. The Volt's AC will typically use 4 - 7 % of your battery to keep you and your passengers comfortable. When the weather turns colder is when you have to decide whether using the electric heat is worth the loss of EV range. Depending on the outside temperature and climate control setting the Volt's resistance heat can use more than 20% of your battery to warm the cabin. For short trips this may be acceptable. There are smarter ways to keep warm in the Volt: 1)Precondition the Volt, while plugged in, for 10 or 20 minutes before you leave, the cabin will be nice and warm. 2) Use the heated seats and steering wheel if equipped. 3) Understand how Engine Assist Heat works. When set to to On (when temperatures drop below 35) the Volt will cycle the gas engine to generate heat for the cabin or else when set to Deferred (when temperatures drop below 15 degrees then Engine Assist Heat will cycle automatically. 4) Use Hold mode for part of your trip to conserve EV range and generate heat for the cabin. 5) Dress warmly.In the energy section there's a "report card" that shows your energy efficiency which includes, terrain, climate controls, and driving style. I've noticed that if I run the A/C the "climate controls" bar is in the red, whereas if I leave it in fan only, it stays in the green.
The Gen2 has a big fat AUTO button that controls both the heat/cool and fan.Was driving home and didn't have the A/C on... (just outside air).
Then I noticed that the A/C came on by itself. It was *really* hot outside (prob close to 100).
Anybody else ever experience this?
