How to survive cold weather in your Leaf when stuck

With the recent news of drivers stuck on the I-95 in snow and freezing conditions, I thought why not create a topic about cold weather survival in your Leaf for emergencies. I was quite concerned when I asked my friends and family what they would do, most of them had no idea how to extend out the heating as long as possible to my surprise.

To start, if I was stuck like those drivers and just became stranded on some road in the middle of a snow storm with no way to get anywhere, I know some of the first steps I would take.

1) Immediate shut off all non-essential power loads like lights, radio, etc.
2) Set the heater to re-circulate air (not worried about foggy windows at this point)
3) Change the vent pattern so all heat is blown into the bottom/face vents and not on the windows since they will conduct the heat away quickly
4) Set the climate control to the lowest value of 60F heating, I would rather feel chilly than to be actually freezing
5) Not sure if I would use emergency flashers or just the parking lights during the night time. The clicking of the flashers would probably get annoying real quick

Some preparation steps before winter for your Leaf (this is probably a given for our Northern neighbors, but the rest of us probably make no winter preparations)
1) Have some small blankets packed away in the back
2) Have some high energy snacks packed away in the back
3) Have some small bottled water packed away in the back
4) Buy one of those "winter emergency kits" for cars

Some other stories from the I-95 freeze about a Tesla driver.

Re: How to survive cold weather in your Leaf when stuck

I think that the best way to stretch out the heat in an EV like the Leaf is to run the heat twice an hour, but leave the seat warmers on continuously - on Low if possible. The car would have to stay in Ready mode. It would probably be worth running the radio, with its negligible power drain. I know that I'd be regretting the legal requirement that all vehicles - even EVs - have no Off setting for the ventilation fan. EVs don't produce carbon monoxide...

With the rare exception, none of the people replying to the Twitter post have figured out that the Tesla is way better than the ICE cars for getting stuck in traffic- even with a small amount of battery power left it should be able to heat for hours. Seems like the owner should know that also, and should be able to contact Tesla to get it figured out....

I think the best mode for heat in that situation is in the floor mode...heat rises.

Agreed. Cold feet make a cold car worse. Occasional switches to Hi/Lo vent mode, and the blower on the lowest setting. Recirculate on full if visibility not needed, partial, aka "auto" if it is needed.

I was thinking the same thing, but imagine you were on your way to a QC station and low battery charge... and then you get stuck there. :o

I think that if one was to survive 24 hours in that situation, minimal heat settings should still be enough to keep you from freezing for a day and still have enough to turtle to the nearest QC station at a low speed. If you could just get the EV power consumption down to a minimal 500 watts for example, then 24 hours of heat would cost roughly 12 kWh of capacity. It would be a touch stretch for a Gen 1 Leaf (with a 24 kWh battery), but I think any of the Gen 2 Leaf, Tesla, Bolts, etc. could swing that without much issue provided they didn't get stranded with less than 33% SOC when it happened.

I choose the Tesla over any of the ICE vehicles, partly because the heater is so efficient compared to running a motor and partly because it is unlikely that the Tesla is REALLY low on battery, although at least as likely as that the ICE vehicle is really low on gas.

Re: How to survive cold weather in your Leaf when stuck

Another interesting bit of the news on this subject. Social media rounds blaming EV for road blocks but it was all untrue.
https://news.yahoo.com/fact-check-traff ... 51578.html
“Roads are jam-blocked by electric cars with dead batteries from idling to keep occupants warm all night,” claimed a Facebook post dated Dec. 29, 2021. “Snows falling, road crews can’t plow due to hundreds of dead battery cars stuck in road blocking everyone else.”
