    just use some 3M crazy velcro on the edges and carpet tape for the center to mount a sheet of 10mm neoprene to the underside
    it might help some

    Was the car plugged in? If so, I would have thought that it would keep the battery at optimal temperature. Sounds like the 10 minutes of driving was needed to warm up the pack.

    I think it keeps the battery warm and cold enough to avoid degradation. I don't think it keeps it within, say, 10C. That would take a fair bit of energy to do.

    Makes sense. I probably wouldn't want to pay for unneeded kWhs with the car plugged in for extended periods.

    I believe Tesla is working on the ability to "schedule" drive times to pre-heat or pre-cool the car while still plugged in so that you don't waste battery power and range starting out very hot or cold. Perhaps in this scenario they'll optimize the battery temperature too.

    It was not plugged in. The roadster would keep the pack heated when cold out and plugged in. It used a fair amount of power to do so. No idea what the model s does. I'm in a garage and no plug at work so I doubt I'll get the chance to find out.

    I'll be in the same boat (no place to plug in at work) when I get my car.

    A newbie question, why is there a limiter when it is cold?

    The chemistry changes when the battery is cold. The lithium tends to precipitate in metal form on one of the electrodes, I think. Anyway, the batteries will degrade rapidly if charged when very cold.

    What, Toronto businesses don't have block heater plug ins for employees? Out here there are 110v plugs all over the place, since an ICE can have a hard time starting after sitting for 8 hours or so on a cold day. One reason Manitoba should be great for EV's; we're used to plugging in our cars all winter anyway!

    Keep in mind a full charge on lowly 110 takes about 65 hours.
