The EV Association of Norway took 5 electric car models for a road trip in the middle of winter to see how they would perform in cold, snowy conditions. Cold temperatures are tough on batteries. Their range is reduced, charging takes longer, and those problems are made worse by using the battery to heat the passenger compartment. The folks at the EV Association of Norway decided it was time to find out if electric cars are ready for prime time in winter driving conditions. The route went from Oslo to Hemsedal, a popular ski resort 3,000 meters above sea level, and back, for a journey of about 700 kilometers.
