Yes the autonomy was short ! ( I doubt I would have made more than 40 miles)

BUT...

Pre-heating gave me a nice warm car
The driving was soft
The car stayed warm and the windows unfrosted using A/C..

Proof is made... That car is still usable in deep cold ! :P

So, -25C / -13F should have turned on the battery warmers at -20C. Was the car "cold soaked" at that temperature (did it sit outside all night in that temperature) ?

Was there any indication on the dash (or anywhere) that the battery heaters were on ?

Did you happen to get a look at the energy consumption page ? I'd like to see what that heater is using for power !!!!!

I think you may win the prize for the lowest temp so far but we may possibly match it later this winter ... how much range do you think you had as the comment on not being able to get 40 miles?

Did you drive 10 miles or 35 miles to make that guess?
Was it still 100% after the preheating?

Just curious. My Leaf will be lucky to ever see 40F.

Can you tell us what the battery temp gauge was reading during the drive (how many bars) ?

Bienvenue!
That's my question also, how many battery bars did you see and was it garaged the night before or did the Leaf sit outside? Personally I have not seen lower than 18F this winter yet (4 battery bars).
Thanks

We were down to 9 F (at night) and still had 4 bars on the battery temp so not sure when it would drop low enough to activate the battery warming system. Of course, when we left our (heated) garage whose air temp was around 60 F the battery was warmed enough so even though the outside temp was very low it would probably take several hours to have any effect. This I would guess is also the beauty of being able to preheat. I noticed that it showed an indicated 1 F in Nashua, NH but not many LEAF's are out that way yet (most have been reported from MA).

My wife just took our new LEAF (picked up 2 days ago) to work in negative six degree (-6 F) weather.

It was garaged with climate control while plugged in. Used 3 battery bars for the 11 mile drive to work. We'll see this afternoon when it is more cold soaked but hopefully much warmer outside (also more downhill)...

I am happy to have our LEAF finally, but the range has been less than stellar with temps below 10 degrees at all times (lower than normal.)

The dismal 2.6 miles/kWh reported on the dash will hopefully improve soon as the temperature rises (also soon).

I thought the leaf disclosure form said the battery warmer kicks in if temp is -4 F degrees. But, it will stop if the battery power is less then 30% (I think).

Lot of questions !!!

The battery temparture indicator was showing 1 bar at the beginning, then, 5 minutes after went up to 2 bars !!!
Yes the car was preheated for 15 minutes prior to my departure.
Yes the car slept outside and was frosted before I started to heat it up.
I checked for an indicator that the battery heater was on but didn't see anything. (only the "cold outisde temp" at startup)
The A/C system was using aroung 4,5KW

Drove around 30 miles and was having only 3 bars left ! Should say that I charged at 80%, not 100%

The short range available was not only created by use of the A/C. I guess the battery was to cold to work properly.
