You’d need an EV with a pretty large battery to drive a total of 200-300kms without charging over a few days in that cold. It would be an expensive model to achieve that.
If that was truly your driving situation, as an avid EV proponent, I’d suggest you not get one. At best, you’d barely manage it. At worst it would end up costing a fortune for tows, additional electric set up (adding a plug at your destination), or tons of hours waiting to charge. It would be an overall shitty experience.
