If it can draw 6kW and you're doing about 0.2 kW/mile then every hour of operation at that level takes away about 6/0.2 or 30 miles of range. Of course that's only at extreme temps, the closer to room temperature it is the less the load on the climate control.

6 kW is just about 8 hp btw, I think that was the figure discussed for an auto AC earlier in the thread..

I think that most if not all heat the seats and steering wheel rather than the air in the vehicle madokie Mar 2012 #6

You aren't going to get away with cooling the seats only in the south.. Fumesucker Mar 2012 #7

Most of the time you'd pre-heat or pre-cool the EV before unplugging it txlibdem Mar 2012 #8

Taxing the batteries. PamW Mar 2012 #12

How is it taxing the batteries when the car is still plugged in? txlibdem Mar 2012 #13

You said the EV's would only have cooling for the seats and wheel.. Fumesucker Mar 2012 #15

Draw well under a kilowatt. Heat is the main killer. Even AC isn't too bad. nt dmallind Mar 2012 #17

The average blow dryer is about a kilowatt.. Fumesucker Mar 2012 #18

Well jeez I can believe you or my car's specs and consumption data dmallind Mar 2012 #26

Have you actually had it in really hot and humid weather yet? Fumesucker Mar 2012 #28

In Feb-Mar? No - but try this dmallind Mar 2012 #29

It looks like 11 miles is cut from your range if I'm reading the display correctly.. Fumesucker Mar 2012 #30

The guessometer is called that for a reason. I get 4.6m/kW. dmallind Mar 2012 #31

Ah, some numbers to work with.. Fumesucker Mar 2012 #33

EXACTLY!!! PamW Mar 2012 #35
