So ass we know the gen 1 battery pack for 2014 has I believe a 10.7 usable size of the batter to get the 38 miles at least rated. So today in NY its been oh about 10 degrees all day. I was able to get 24miles out of what the monitor showed 11.3kwh. How can this be? Now my 4yr old volt has been averaging 10.3 for the last few seasons which is expected after being 4 years old so degradation is great. But how is it possible to get 11.3 on such a cold day? Note I did preheat the volt for one iteration of 10 minutes or cycle. Is it possible the 11.3kwh includes the extra amountt consumed while plugged in and preheating/pre conditioning?

Probably preheat while plugged in and it didnt charge fully?

Edit: I think that would show you using that electricity, and it will burn about 1 kw in 10 min at max power, so if it didn't quite charge up all the way to full after preheating it would mean you used a little more than a full charge. I get similar if I charge at lunch, but I haven't noticed with preheating, but I don't watch that closely.

In ERDTT mode the electricity generated by gas is generally not added to the total (the car measures current in and out of the battery as far as I know, so is able to account for most of it generated by engine or not), although I think the accounting gets off sometimes. For example, my latest run with ERDTT showed this, my usual number is 9.4 kwh and this shows 9.2 kwh, so none of the electricity was added in (a whopping 29 MPGe or so):

I think the less trustworthy numbers are miles on gas and electric as those get accounted strangely in ERDTT mode in my 2012, especially if I put the car on "Fan only" climate with very cold temps (like single digits F or less). This is why I think the OP was credited with using some electricity that was recharged before he left, but not recharged all the way to reset the counter.

The fan only mode might cause the gauge to get off as the engine might run a lot more putting energy into the battery, but not sure, I think that just messes with your EV vs Gas miles, not so much the kwh used display.
