In winter your range will be less, perhaps 40% less. You need to let go of the ICE paradigm of filling up the fuel tank and driving until the fuel gauge is near empty. In an EV you will stop more often to charge but the charging stops will be short, usually much less than 30 minutes. You won’t want to charge above 80% when on the road (takes too long once the state of charge is at 80% to charge to 90% or more.)
Take the time to learn how to use A Better Route Planner (ABRP). This is available on the internet and also as an app for your phone. ABRP will help you by showing, in detail, recommended charging stops along a route.
With the CCS charging adapter (available in S. Korea and coming to N.A.) you will have more charging options when on a trip.
