I find myself a bit of an outcast in my social groups. My conservative friends dislike EVs, but I very much love them and will be buying an EV next. I'm holding out for a solid state battery generation. When it's -40c and you're running the video security systems. It only drains about 1% a day. Yes you have less range, but so does gasoline. About the same amount of loss. Turning it on... harder for gasoline. Better plug in those block heaters! Blackout at your house because the grid failed because renewables arent generating? Your car is your house battery backup. Very poor traction? Better put sandbags in the bed of your truck. Oh wait not a problem for heavy EVs. Not to mention traction control is next level in EVs. The cherry on top... 0-60 for EVs is amazing!

> When it's -40c and you're running the video security systems. It only drains about 1% a day. At least with Tesla, it isn't this good. Running sentry mode will cost a lot more than 1% a day. Best to leave it off if the car will be sitting at the airport for days, for example. Otherwise, I agree. EVs in the winter work great for many (but, of course not all) use cases.

My only experience with -40C was in Harbin where my cell phone and camera battery died quickly. This was back in 2006 though, and I’m guessing the batteries were just not ready for it.

> Yes you have less range, but so does gasoline. About the same amount of loss. This is absolutely not the case. The worst case scenario for ICEs (cold starts, intermittent short trips so the engine block doesn't get heat) is 15%. The average for EV in subfreezing is about 24% loss. And up to 39% when you're on longer trips and heating the cabin for extended periods.

  you say 'average ev' to include the 1st generation evs that are trash and had no cold weather capabilities. Yes -50% range can be expected. Terrible! The kia soul for example, which originally had 150km range has been upgraded now. I believe the cold weather package is standard now? Today in 3rd generation evs, you have to cross the heat pump temp limit of -25c for there to be worse then ICE range losses. There's obviously always going to be rough losses. Afterall, the colder it is, the more I want to jack up the heat. Ford, chevy, and vw I believe are still in 2nd gen? Though honestly I havent heard how well the new ultium are doing for chevy? I believe 3rd gens, jaguar, audi, and tesla at -20c will be around -5% range loss or so? Personally I'm waiting on 4th gen with solid state batteries in hopes/expectations they handle the cold weather better. afterall it is -15c right now for me. Toyota has all the patents and might be first to market?
