We have a new Leaf which has just now started issuing warnings about low temperature outside. (It's been a ridiculously warm winter in Maryland so far. And ridiculously low gas prices, which makes you wonder, why get one now?). But it doesn't seem to affect its mileage estimation, which is well over 90 miles. Does it lie? At what point do you know it's not going to make it? What am i supposed to do about that low temperature warning?
This was the first time I'd driven a Leaf specifically so my experience is limited. (I belong to an electric car sharing service in Oslo and usually get one of the smaller cars, which are fine for errands around town... in retrospect I should stick to that instead of trekking out to the airport!)
It was about -6/7C and it did not seem to be anticipating the decreased range due to the cold. When I got going it said I had 130km left, and the estimation decreased faster than my distance traveled increased, despite the fact that I was driving slowly and unaggressively and I only used the heat very occasionally to defrost the windshield. When I got to the airport I'd driven about 60km and it said I had only 25km left. Whoops!
Luckily I had anticipated needing to charge at the airport because of the cold, so I arrived early and we ate dinner there to give it plenty of time. After 2.5 hours charging it was up to 55km or so, or *maybe* just enough to get home and then back to the parking/charging spot. Probably should have charged longer but I wanted to return it on time. As we got closer it was clear we weren't going to be able to make it home, so we headed straight to return it. The last few km were a bit tense and I pulled in to the parking/charging spot in Turtle mode.
Now we were "stranded" with the kiddo and lots of luggage. We thought we were going to have to lug everything over to the bus but we were saved by Louise, who was available to come rescue us. Lots of lessons learned. :-)
