My 2014 Chevy Volt pulls almost 6kW initially in comfort mode when you turn on
the heat. It will ramp back to about 3kW if you keep the heat cranked up
(which I do on cold days) This takes a big hit on my range since the usable
pack is only about 11kW anyhow and I have a 21 mile commute that takes 35
minutes. On the colder days (below 30F) I run out of battery and drive on gas
for a mile or two. That's the price of comfort I guess!

My son has a Bolt in Alaska and he has a short 3 mile commute but
has to go to max heater energy just to keep the windows
defogged. I notice that too down here in Marland.
Humans put out a LOT of breath andhumidity and in the cold
that is all going to condense on the window. So he uses pre-heat
and conditioning Fully HALF of his battery energy goes to
defrosting and heat.
But with p re-heat, it does not affect range that much.
But is certainly a contributor to EV design
