EV Road Trip in Winter: Why Your Range Estimate Lies

Electric vehicle range estimates assume ideal conditions. In cold weather, battery chemistry reduces capacity, cabin heating draws significant power, and regenerative braking efficiency drops. The result: real-world winter range can be 25–35% less than what your dashboard shows.

TripCaptain calculates weather-adjusted effective range based on actual temperature, precipitation, and wind conditions along your route. Charging stops are placed at 80% of effective range to maintain safety margin, and charge time estimates account for cold-weather charging speed reductions.

The platform distinguishes between Tesla Supercharger and public CCS networks, with different charging speed assumptions for more accurate planning.
