Impact of Winter Conditions on Electric Vehicle Performance

A recent study by the Canadian Automobile Association (CAA) tested the performance of electric vehicles (EVs) in winter conditions, revealing significant drops in range and charging efficiency. The study involved driving 14 EV models in sub-zero temperatures from Ottawa to Mont Tremblant, measuring their effective range and charging times. Results showed that most vehicles performed 14 to 39 percent worse than their advertised range, with some EVs, like the Chevrolet Silverado EV and Polestar 2, faring better. CAA advocates for a standardized labeling system that includes winter performance data to better inform consumers. The study also provided tips for maximizing EV performance in cold weather.
