Was driving an EV in freezing / snowy conditions the other day, up a mountain, with a blinking battery light. I couldn't believe how much running the heater and AC (required for demisting), the cold and going up a hill sucked the battery. In the same car only a week before in much better weather, I did a similar trip, twice.
