But if I read the article right, the car IS adjusting its display for temperature. When the temp went down, the calculated available miles went down also -- and almost accurately, that is, the car went dead about when the miles-left display went to zero.
The question I'd have is, how much current would they have to divert to keep the batteries warm? It seems like the juice expended to hold the battery pack at 20C might be less than the capacity lost by letting the batteries go down to an ambient -5C.
Or, they could provide what a lot of east-coast cars have, a built in engine-block heater that you plug in to a 110V extension cord overnight. Except in this case it would be a battery pack warmer, but the same idea, keep the important bits toasty over a cold night.

Showing that the range is zero when the battery is dead is not hard. The problem is when the displayed range drops faster than you're traveling, and if that wasn't the problem, he wouldn't have been stranded. If it was adjusting its display for temperature, it wouldn't have been wrong. Or, they could provide what a lot of east-coast cars have, a built in engine-block heater that you plug in to a 110V extension cord overnight. Had he plugged the car into a 110V outlet overnight, the battery would have been charged in the morning.
